Matches a pattern that lost clearly more than the trading costs in the backtests.
- Consensus side under 30¢Longshots (0.05–0.30) lost −29.5 % a trade pooled (n 1,625; −22 % in spring, −35 % in October): the strongest effect in the backtests.
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.
23.0¢ price + 1.0¢ spread + 0.7¢ fee (Politics 4%). 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.
