This market resolved "Knicks" on 2026-06-14, verified on-chain against Polymarket's settlement — the rex engine called it correctly.
On 2026-06-13, the rex engine's echo screen flagged this market and took "Knicks" at 37¢ — the market was pricing that outcome at 37%, so a correct call would pay 2.74× the stake. 0.9 days later the market resolved on-chain, and the position settled as a win: +$86.99 on a $50 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.
One win proves nothing — that's the point of publishing all of them. This verdict is one row in a forward ledger that only ever grows, where the hit rate is computed over every settled position, losses included.
