In July 2024, Jack Dorsey sent an internal memo to Block's employees with the subject line "fn block." The message announced the dissolution of every business unit boundary inside the company — Square, Cash App, Tidal, TBD, Proto, the foundational teams — all of it reorganized by function. Engineering would sit with engineering. Design with design. The silos that had defined the company for over a decade were being demolished. Dorsey described the restructuring as a return to "how we started as a company," which was a revealing phrase from a CEO whose company had, in the intervening years, acquired a $29 billion Australian buy-now-pay-later platform, begun designing Bitcoin mining chips, shipped a hardware wallet shaped like a river stone, and accumulated a balance sheet position in Bitcoin large enough to move markets. The memo warned employees the changes might feel "big and disruptive or uncomfortable." That it might also feel like the most honest articulation of what Block has always been — a company that cannot quite decide whether it is a payments infrastructure provider, a consumer finance super-app, or a Bitcoin ideological project — went unstated.
Block, Inc. trades on the New York Stock Exchange under the ticker XYZ, a symbol it selected after changing its name from Square in December 2021. The ticker is a joke, or a statement of ambition, or both — the last three letters of the alphabet, a mathematical placeholder for an unknown variable. The name change itself was an act of narrative engineering: Square, the product that launched the company, had become too small a container for what Dorsey wanted to build. But containers serve a purpose. They tell the market, and the employees, and the customers, what you are. Block's central tension — the one that has defined it from inception and will determine whether it compounds into a generational financial technology company or fragments under the weight of its own ambitions — is that it has always been better at destroying containers than filling them.

The Glass Brick and the Impossible Transaction
The origin story has been told so many times it has calcified into corporate mythology, but the details remain instructive. In 2009, Jim McKelvey — a glassblowing artist and serial entrepreneur in St. Louis — lost a sale on a piece of art because he couldn't accept a customer's American Express card. The transaction was perhaps $2,000. The customer walked away. McKelvey called his friend Jack Dorsey, who had co-founded Twitter three years earlier and had recently been pushed out of the CEO role there, and the two began sketching what would become Square.
McKelvey was the unlikely half of the pair. A Princeton-educated computer scientist who had chosen to spend his career making glass art and starting oddball businesses in the Midwest rather than optimizing for Silicon Valley prestige. He possessed the rare combination of technical sophistication and craft-world sensibility that allowed him to see what the payments industry looked like from the other side of the counter — the side where a small merchant loses a sale because Visa's infrastructure was designed for Walmart, not for a glassblower at a craft fair. His later book,
The Innovation Stack, would codify this perspective into a theory of how companies build interlocking sets of innovations that, taken together, create defensibility no single feature can provide.
Dorsey brought something else entirely. Born in St. Louis in 1976, he had been obsessed since adolescence with the real-time pulse of cities — dispatch systems, taxi routing, the way information moved through urban networks. His first company, a dispatch software startup, failed. Twitter had emerged from his fascination with status updates as a form of urban dispatch. Now he turned that same instinct toward a different network: the flow of money through the American economy, and the millions of small businesses that had been excluded from it.
The first Square reader — a small white dongle that plugged into a smartphone's headphone jack — shipped in 2010. It was, at a hardware level, almost absurdly simple: a magnetic stripe reader that converted card swipe data into audio signals. The genius was not the reader. The genius was the decision to give it away for free, charge a flat 2.75% per transaction with no monthly fees, no contracts, no merchant account applications, and to underwrite the risk algorithmically rather than through the traditional process of credit checks and manual review that had kept small merchants locked out of card acceptance for decades.
This was not a marginal improvement. It was a category redefinition. The incumbent payment processors — First Data, Heartland, the tangled web of ISOs and acquiring banks — operated on a model of opacity: tiered pricing, long-term contracts, hidden fees, batch settlement. Square flattened the entire structure into a single number. The business model was the product.
Two Economies, One Company
What happened next reveals the strategic DNA that would define Block for the next fifteen years. Square had entered the market as a tool for micro-merchants — the farmer's market vendor, the food truck operator, the yoga instructor who wanted to accept cards. But the company quickly discovered something the incumbents already knew: micro-merchants generate micro-revenue. A taco truck processing $30,000 a year at 2.75% yields $825 in gross payment revenue.
Scale that across tens of thousands of sellers and you have a real business, but not one that justifies a venture-backed growth trajectory.
So Square began moving upmarket. Square Stand. Square Register. Square for Restaurants. Square for Retail. Point-of-sale software that replaced not just the card reader but the entire cash register, the inventory management system, the employee scheduling tool, the payroll provider. Each layer of software increased the switching cost and, critically, the gross profit per seller. By the time Square went public in November 2015 at an $2.9 billion valuation — a down round from its last private valuation of $6 billion — it had begun the transformation from a payments company into a commerce operating system.
But the IPO masked a deeper structural challenge. Square's merchant business was grinding — high-quality, recurring, but fundamentally limited by the growth rate of small business formation and the company's ability to push upmarket against entrenched competitors like Toast, Clover, and Shopify. The real growth engine was being built elsewhere, almost by accident.
Cash App launched in 2013 as Square Cash, a peer-to-peer payments service conceived as a direct competitor to Venmo. It was, initially, a sideshow — a small team inside Square working on a consumer product while the rest of the company focused on merchants. The product was spartan: send money to a friend via email, then via a mobile app, then via a unique identifier called a $cashtag. No social feed, no emoji reactions, none of the playful design language that had made Venmo a cultural phenomenon among millennials.
What Cash App had instead was distribution in communities that Venmo didn't reach. Through a combination of deliberate marketing — heavy investment in hip-hop sponsorships, partnerships with artists, a viral referral program — and organic adoption, Cash App became the dominant peer-to-peer payments tool in Black and Hispanic communities across the American South and Midwest. By 2018, Cash App had surpassed Venmo in downloads. By 2020, it had become something far more interesting than a payments app.
Cash App is not a peer-to-peer payments app. It's a financial services ecosystem.
The transformation happened in layers. Direct deposit (2018) turned Cash App into a primary bank account for millions of unbanked and underbanked Americans. The Cash Card — a Visa debit card linked to Cash App balances — turned digital money into physical spending power. Bitcoin trading (2018) turned Cash App into a brokerage. Tax filing (2022, via the acquisition of Credit Karma Tax) turned it into a seasonal touchpoint. Cash App Pay turned it into a checkout button. Each layer deepened engagement, increased the number of financial transactions flowing through the platform, and — crucially — shifted Cash App's revenue model from transaction fees to a diversified mix of interchange, instant-deposit fees, Bitcoin margin, and subscription revenue.
By 2023, Cash App was generating more gross profit than Square's entire seller ecosystem. The side project had consumed the main business. Block had become, almost despite itself, a consumer finance company that also happened to sell point-of-sale hardware to restaurants.
The Afterpay Wager
On August 1, 2021, Block announced it would acquire Afterpay, the Australian buy-now-pay-later pioneer, for approximately $29 billion in an all-stock deal. The price was staggering — Afterpay had generated total income of A$644.9 million (approximately $470 million) in the six months ending December 2021, against operating losses of A$263.7 million. Block was paying roughly 60 times annualized revenue for a company that was losing money at scale.
The strategic logic, if you squinted, was coherent. Afterpay connected the two halves of Block's business: it gave Square sellers a new payment option that demonstrably increased average order values and conversion rates, and it gave Cash App users access to short-term credit — the one financial product the platform conspicuously lacked. The acquisition was, in Dorsey's framing, the bridge between the merchant economy and the consumer economy, the missing piece of a two-sided network that had operated for a decade as two separate networks pretending to be one.
The timing was catastrophic. By the time the deal closed in January 2022, interest rates were rising, fintech valuations were collapsing, and buy-now-pay-later as a category was under regulatory scrutiny in multiple jurisdictions. Block's stock, which had peaked above $280 in August 2021, fell below $60 by the end of 2022. The Afterpay acquisition, funded entirely in stock, had been priced at the absolute zenith of the fintech bubble.
Afterpay's financials at the time of Block's acquisition
| Metric | H1 FY2022 (Dec 2021) | H1 FY2021 (Dec 2020) |
|---|
| Total Income | A$644.9M | A$417.2M |
| Gross Profit | A$463.3M | A$306.9M |
| Receivables Impairment | A$176.8M | A$72.1M |
| Operating Loss | A$(263.7)M | A$(68.2)M |
| Loss After Tax | A$(345.5)M | A$(79.2)M |
The receivables impairment number tells the real story. Afterpay's model — four interest-free installments, revenue from merchant fees rather than consumer interest — was elegant in theory but deeply exposed to credit risk in practice. The A$176.8 million in impairment losses for the first half of fiscal 2022, up 145% year-over-year, reflected the fundamental challenge of extending unsecured credit to consumers without rigorous underwriting. Block was acquiring a lending business at the moment when lending businesses become most dangerous.
The Bitcoin Maximalist in the Corner Office
No account of Block can proceed without reckoning with Dorsey's relationship to Bitcoin, which is not merely strategic but ideological, spiritual, bordering on messianic. Among Fortune 500 CEOs, Dorsey occupies a unique position: he is perhaps the only one who has described a cryptocurrency as the single most important technology for the future of the human race and then restructured a publicly traded company around that conviction.
The Bitcoin investments started small. Cash App introduced Bitcoin trading in early 2018. By 2020, Bitcoin revenue — the gross value of Bitcoin bought and sold through Cash App — had exploded, reaching $4.6 billion in 2020 (though with razor-thin margins, as the vast majority represented the cost of Bitcoin itself). The revenue line was enormous and misleading in equal measure: it made Block look like a much larger company by revenue than it was by gross profit.
But the Bitcoin strategy was never primarily about Cash App trading revenue. It was about something larger and harder to quantify. In 2020, Block placed $50 million of its corporate treasury into Bitcoin — one of the first major public companies to do so. Dorsey created a new business unit called TBD (later renamed to just TBD Web5) focused on building decentralized financial infrastructure. He launched Spiral (formerly Square Crypto), an independently-operated initiative to fund open-source Bitcoin development. In April 2024, Block announced a Bitcoin mining rig — hardware designed in-house, an outgrowth of the company's Proto team, which was building custom Bitcoin mining chips.
The scope of the Bitcoin bet is remarkable. Block holds approximately 8,211 BTC on its balance sheet (as of early 2024). It allocates 10% of its monthly gross profit from Bitcoin products to purchase additional Bitcoin. It designs and manufactures Bitkey, a self-custody hardware wallet. It builds mining hardware. It funds open-source protocol development. It allows Square merchants to convert a portion of their daily sales into Bitcoin via a product called Bitcoin Conversions.
We've already been working with over 100 merchants to develop the alpha version of Bitcoin Conversions.
This is not a side bet. This is architectural. Dorsey has stated publicly that he believes Bitcoin will become the native currency of the internet, and he has organized Block's resource allocation around that belief. The question for investors is whether this constitutes visionary positioning or an ideological tax levied on shareholders by a founder-CEO whose conviction outpaces the market's timeline.
The Dual-CEO Problem, Solved and Unsolved
For nearly six years, from 2015 to 2021, Jack Dorsey served simultaneously as CEO of Square and CEO of Twitter. The arrangement was unprecedented among major technology companies and drew persistent criticism from investors who argued, not unreasonably, that running two public companies at once was at best a dilution of attention and at worst a governance failure.
Dorsey's defense was characteristically minimalist: he compared himself to a music producer working across multiple albums. The analogy was charming and unpersuasive. During the dual-CEO period, Square's stock performance was strong but punctuated by strategic drift — the company launched initiatives (Square Capital, Caviar, Weebly) that were subsequently sold or de-emphasized, suggesting a company searching for its next act without the focused leadership to find it.
The resolution came in November 2021, when Dorsey resigned as Twitter CEO, posting a resignation letter that began: "I've decided to leave Twitter because I believe the company is ready to move on from its founders." Fourteen months later,
Elon Musk would complete his acquisition of the platform, vindicating Dorsey's decision to exit in ways he could not have anticipated.
With Twitter behind him, Dorsey threw his full weight into Block. The results were — characteristically — contradictory. On one hand, the company began executing with greater discipline: the 2024 reorganization by function, the strict 12,000-employee headcount cap, the layoffs of approximately 1,000 employees (roughly 10% of staff), the elimination of traditional performance reviews in favor of more frequent feedback cycles. On the other, Dorsey's singular focus on Bitcoin and decentralized technologies continued to create tension with a market that wanted Block to be a payments company with good unit economics, not a cryptocurrency R&D lab with a payments business attached.

In early 2025, Block notified hundreds more employees that their positions might be eliminated. Up to 10% of the remaining workforce — roughly 1,100 people from a base of fewer than 11,000 — was at risk. The cuts came during annual performance reviews, a coupling that suggested Block was using the review process as a mechanism for structural cost reduction rather than simple performance management. Analysts expected the company to report Q4 2024 adjusted earnings of approximately $403 million, or 68 cents per share, on revenue of $6.25 billion. The market was watching to see if the operational discipline would translate into margin expansion.
The Shape of the Network
The strategic architecture of Block, stripped to its essentials, is an attempt to build a two-sided financial network — merchants on one side, consumers on the other — and to capture value at every point of intersection. This is not original. PayPal pursued the same vision. So did every major bank in America. What distinguishes Block is the specificity of its entry points and the ambition of its connecting tissue.
On the merchant side, Square processes approximately $227 billion in annualized gross payment volume across an estimated four million sellers. The product suite — hardware (readers, terminals, registers), software (point-of-sale, inventory, payroll, invoicing, online ordering), and financial services (Square Loans, Square Banking, instant deposits) — creates a full-stack commerce operating system. Each new product deepens the relationship, increases switching costs, and generates incremental gross profit per seller.
On the consumer side, Cash App serves approximately 57 million monthly transacting actives. The product surface — peer-to-peer transfers, direct deposit, the Cash Card, Bitcoin trading, stock investing, tax filing, Cash App Pay for e-commerce checkout, and now buy-now-pay-later via Afterpay — creates a financial services super-app for a demographic that traditional banks have either underserved or actively penalized through overdraft fees, minimum balance requirements, and branch networks concentrated in affluent zip codes.
The bridge between the two sides is payments itself. When a Cash App user pays at a Square merchant, Block captures value on both sides of the transaction: the merchant discount rate from the seller and the interchange revenue (plus any instant-deposit or BNPL fee) from the consumer. This closed-loop transaction is the holy grail of payments economics — it eliminates the network fee paid to Visa or Mastercard and allows Block to set its own economics. The problem, as of 2024, is that closed-loop transactions remain a small fraction of total volume. The overwhelming majority of Cash App spending occurs at non-Square merchants, and the overwhelming majority of Square transactions are funded by non-Cash App payment methods.
This is the fundamental question of Block's long-term value. Can it close the loop? Can the functional reorganization — which explicitly aims to break down the walls between Cash App and Square engineering teams — accelerate the integration of two ecosystems that grew up as separate products with separate teams, separate cultures, and separate users?
The AI Gambit and the Goose
Among the less noticed elements of Block's 2024–2025 transformation was the development of an internal AI tool called Goose. The name is whimsical; the ambition is not. Goose is Block's attempt to build an AI-native operating layer across the entire company — automating customer support, accelerating software development, and, in Dorsey's framing, making Block "the most AI-native enterprise in the world."
The AI strategy intersects with the headcount discipline in ways that are mutually reinforcing. If Block can use AI to automate work that previously required human employees, the 12,000-person headcount cap becomes not a constraint but an efficiency target — a forcing function that drives AI adoption internally. The question is whether the AI tools are genuinely productive or whether Block is prematurely cutting headcount in anticipation of productivity gains that haven't materialized. The answer, as of mid-2025, is unknowable. What's clear is that Dorsey has bet that the organizational cost of rebuilding — the disruption of the functional reorganization, the pain of layoffs, the loss of institutional knowledge — will be more than offset by the compounding returns of a leaner, AI-augmented workforce.
The Ideological Company
There is a type of technology company — rare, volatile, capable of extraordinary returns and extraordinary destruction — that is organized around an ideology rather than a market opportunity. Tesla is one. Block is another.
Dorsey's ideology is specific: financial systems should be open, permissionless, and built on protocols rather than platforms. Bitcoin is the monetary expression of this ideology. Cash App's mission to serve the underbanked is its social expression. The functional reorganization is its organizational expression. The open-source funding of Bitcoin development through Spiral, the decentralized identity work of TBD, the self-custody ethos of Bitkey — all of these flow from a coherent worldview about how financial infrastructure should be designed.
The advantage of an ideological company is conviction. Block makes long-duration bets — Bitcoin mining hardware, custom chip design, protocol-level R&D — that a purely market-driven company would never fund because the payoff timeline is too distant and the intermediate optionality too uncertain. The disadvantage is that ideology can become dogma. Dorsey's Bitcoin maximalism (he has been publicly dismissive of all cryptocurrencies other than Bitcoin) has narrowed Block's crypto strategy in ways that may prove prescient or may prove costly. The explosion of DeFi, NFTs, and alternative Layer 1 blockchains between 2020 and 2022 created enormous value — almost none of which accrued to Block, because Block only does Bitcoin.
While his Bitcoin-only philosophy is off-putting to many in the broader crypto world, his relentless quest to expand the reach of Bitcoin while also running a highly profitable public company makes Dorsey and Block a unique force in the industry.
The comparison to Tesla is instructive in another way. Elon Musk's ideological commitment to sustainable energy created a company that endured near-bankruptcy multiple times but ultimately reshaped the global automotive industry. It also created a company whose stock price was, for long stretches, a referendum on faith in Musk himself rather than on the fundamentals of the business. Block operates in the same territory. The question is not whether Dorsey is right about Bitcoin's long-term significance — he may well be — but whether a public company is the right vehicle for an ideological project, and whether shareholders are being adequately compensated for the conviction premium embedded in Block's capital allocation.
St. Louis to San Francisco to Everywhere
There is a detail about Block's origin that rarely receives adequate attention: it was founded in St. Louis. Not San Francisco, not New York, not Austin. St. Louis — a city whose economic trajectory over the past half-century has been a case study in American deindustrialization and urban decline, a city where the gap between the financial system's infrastructure and the needs of small business owners was not abstract but physical, visible, felt.
McKelvey has spoken about this repeatedly. The innovation that became Square was not born in a Stanford dorm room but in a Midwestern studio where a craftsman couldn't accept a credit card. The first users were not Palo Alto coffee shops but St. Louis barbershops, Kansas City food vendors, Memphis music stores. Cash App's early growth was not among coastal millennials but among communities in the South and Midwest where banking infrastructure was thinnest and the need for low-cost financial services was greatest.
This geographic and demographic reality shaped Block's product philosophy in ways that persist. Cash App's fee-free direct deposit, its integration with government benefit payments, its Cash Card that works at any merchant accepting Visa — these are not features designed for people with Chase Private Client accounts. They are features designed for people whose relationship with the traditional banking system is adversarial, expensive, or nonexistent. Block's total addressable market is not "everyone who pays for things" but, more precisely, "everyone whom the existing financial system has failed to serve efficiently." That market is enormous. It is also harder to monetize per user than the affluent segment, which is why Block's gross profit per Cash App active (~$70 annually) remains a fraction of what a traditional bank earns per checking account customer.
The Merchant Who Mines Bitcoin
In April 2024, Block announced its Bitcoin mining rig — a piece of hardware that represented the convergence of several previously separate strategic threads. The Proto team, which had been designing custom mining chips (ASICs) in-house, produced a mining system that Dorsey described as an effort to diversify the mining industry away from its dependence on a small oligopoly of Chinese manufacturers, primarily Bitmain.
The mining initiative was ambitious and, by conventional fintech standards, bizarre. Here was a payments company — one that processes credit card transactions for coffee shops — designing semiconductor chips and manufacturing industrial mining equipment. The logic, from Dorsey's perspective, was straightforward: if Bitcoin is to become the native currency of the internet, its mining infrastructure must be decentralized, accessible, and not controlled by a handful of hardware manufacturers in a single country. Block, with its hardware design capabilities (honed through years of building payment terminals) and its Bitcoin conviction, was uniquely positioned to enter this market.
The market received the announcement with a mixture of fascination and skepticism. Mining hardware is a commodity business with brutal margin dynamics and cyclical demand tied to Bitcoin's price. Block was entering a market it had no experience in, against incumbents with years of ASIC design expertise, in service of an ideological goal that shareholders had not explicitly signed up for.
And yet. The Bitcoin Conversions product — which lets Square merchants automatically convert 1% to 10% of their daily sales into Bitcoin, moving it into their personal Cash App — represented a different kind of integration, one that quietly connected the merchant economy, the consumer platform, and the Bitcoin thesis in a single product workflow. A flower shop in Nashville processes a $45 sale on Square. Ten percent — $4.50 — is automatically converted to Bitcoin and deposited in the shop owner's Cash App. Block earns the merchant discount on the sale, the Bitcoin trading spread on the conversion, and the ongoing engagement of a Cash App user whose Bitcoin holdings give her a reason to open the app every day.
It's a small product. It may never be a large product. But it is an almost perfect microcosm of what Block is trying to build: a closed loop between commerce, consumer finance, and Bitcoin, with Block capturing value at every node.
The Wallet That Looks Like a Stone
One detail crystallizes Block's peculiar position in the technology landscape. Bitkey, the company's self-custody Bitcoin wallet, is a piece of hardware designed to allow individuals to hold their own Bitcoin without relying on an exchange or custodian. It shipped in early 2024. It is small, smooth, and shaped like a river stone — a physical object so deliberately organic in its design that it looks like something you'd find in a meditation garden, not on a shelf at Best Buy.
The design is intentional. Self-custody is, in the Bitcoin world, the purist position — the belief that "not your keys, not your coins" is not merely a slogan but a foundational principle. By building Bitkey, Block was making a product that could, in theory, reduce Cash App's Bitcoin custody revenue by encouraging users to move their Bitcoin off-platform. It was a product that prioritized ideology over immediate monetization, protocol over platform.
Dorsey's willingness to build products that compete with his own company's revenue streams — to ship a self-custody wallet when he runs a custodial Bitcoin exchange — is either the clearest sign of strategic integrity in fintech or the clearest sign that Block's capital allocation is driven by the CEO's philosophical commitments rather than by shareholder value maximization. The answer depends on your time horizon and your beliefs about Bitcoin.
Cash App booked $66 million in Bitcoin-related gross profit in a single quarter of early 2024. Somewhere in Nashville, a merchant converts her daily sales into Bitcoin through Square and holds them in a stone-shaped wallet she bought from the same company that processed the original transaction. The loop, for the first time, is almost closed.
