This market resolved against "Chicago White Sox" on 2026-06-25, verified on-chain against Polymarket's settlement — the polymax engine called it wrong, and logs the loss anyway.
On 2026-06-24, the polymax engine's echo screen flagged this market and took "Chicago White Sox" at 33¢ — the market was pricing that outcome at 33%, so a correct call would pay 3.08× the stake. 0.0 days later the market resolved on-chain, and the position settled as a loss: −$100.00, the full stake.
echo is one of the engine's ground-truth strategies: across 175 out-of-sample historical positions it hit 64% (95% CI 56.7–70.9%), a +13.3-point edge over the market's implied odds, returning +27.5% per bet. This position was sized with fractional Kelly from those numbers — not from a hunch.
The engine publishes its losses on purpose: a 64%-hit-rate strategy still loses 36% of the time, and any track record without losses on display is marketing, not measurement. This one is permanently archived on the losses page.
