73% of Polymarket Bets End in No and Smart Traders Are Profiting From It

The most counterintuitive finding in prediction market data is also the most actionable. Polymarket publishes on its own accuracy page that 73.3% of all resolved markets on the platform end in a No outcome, meaning the event being predicted did not happen. An engineer named Sterling Crispin confirmed this independently by building a bot that automatically buys No on every non-sports market it finds, achieving a success rate of 73.4%, nearly identical to the platform's own data. The contrarian edge is not a secret strategy known only to insiders. It is a structural feature of how prediction markets work, baked in by the fact that most questions are framed around specific events that must materialize by a deadline, giving the status quo a permanent built-in advantage.

Professional bettor Domer, one of Polymarket's biggest earners with over $400,000 in winnings, has built his entire strategy around this principle. His most striking win came from betting $100,000 that Cardinal Robert Francis Prevost would become the next pope when the market gave it only a 5% probability. He had previously called Sam Bankman-Fried's 25-year sentence and Sam Altman's 2023 firing at OpenAI correctly, each time betting against the crowd's emotional read of the situation rather than following the momentum. This year's prediction market landscape has been particularly rich with overpriced absurdity, from contracts on whether the US will acquire Greenland before end of 2026 that generated nearly $33 million in volume, to polls on alien life confirmation and dollar collapse. Each of these represents a market where narrative bias has pushed odds well above what rational probability analysis would support, and where a disciplined No position has historically been the higher expected value bet.

73.3% No resolution rate being confirmed independently by a bot with 73.4% accuracy is about as robust a validation as you get for a trading edge — when Polymarket's own data and an independent replication match to one decimal place, that's not noise.
