Trench War

You're seeing Trench War when competitors match each other's pricing, features, and marketing spend move for move — market share barely shifts despite enormous investment from both sides.

You're seeing Trench War when an industry's profit margins compress as competitors spend more and more to maintain the same positions — everyone is fighting harder for the same ground.

If every competitive move triggers an equal and opposite reaction and your market share hasn't budged in quarters, you're in a trench war. Stop fighting harder on the same front. Invest that energy in finding a completely different angle of attack that the competitor can't or won't match.

Knight faced trench warfare against Adidas and Reebok throughout the 1980s and 1990s — competitors with similar products fighting for the same retail shelf space and athlete endorsements. Rather than continuing to escalate on the same fronts, Knight flanked the trench by transforming Nike from a shoe company into a lifestyle brand. The "Just Do It" campaign, the Air Jordan partnership, and Nike's move into apparel and culture shifted competition from product features to brand identity — a front where Nike's storytelling and athlete relationships gave it structural advantages competitors couldn't match with incremental product improvements. Founders stuck in trench wars should look for Knight's lesson: change the dimension of competition entirely.
