Research grade
NeutralNo at 100%
No measured edge either way. The plain consensus (5+ holders, 60 %+, held to resolution) lost −4.8 % a trade after costs (n 10,051, 95 % CI −6.5 to −3.1 %).
- Side priced over 95¢0.90–0.99 was −0.2 % a trade (n 4,210); above 95¢ little is left to win and the backtests' bands stop at 0.95.
Backtest of Oct 22 2026: one entry per market, held to resolution, after a 1¢ half-spread and Polymarket's taker fees. The grade never goes above “Research candidate”: no rule passed the multiple-testing check. It is not a forecast and not advice.

EV Calculator
Consensus % is how many tracked traders hold a side, not a win probability.
99.8¢ price + 1.0¢ spread + 0.0¢ fee (Sports 5%). Win more often than this and the bet pays.
A market order pays the taker fee and crosses the spread (assumed 1.0¢); a limit order pays no fee but may not fill. The fee category is a guess from the title.
