Matches a pattern that lost clearly more than the plain consensus in our tests.
- Consensus side under 30¢Full year, out of sample: 0.05–0.30 lost −8.1 % a trade (n 11,568), under 0.20 −20.5 % (n 3,615). Oct 22 backtest: −29.5 % (n 1,625). The strongest effect in every test.
- Spread or totalOct 22 backtest: spreads and totals −14.5 % a trade in spring (95 % CI −27 to −1), +1.5 % in October: no edge.
- Fewer than 5 holdersEvery backtest needed 5+ holders; with fewer nothing was measured.
The rules come from our Oct 22 2026 backtest (one entry per market, held to resolution, after a 1¢ half-spread and Polymarket's taker fees). Our full-year test without hindsight (Oct 26 2026) found none of them profitable out of sample, and the plain consensus lost −3.0 % a trade. The grade describes the market; it is not a forecast, not an edge and not advice.

Consensus % is how many tracked traders hold a side, not a win probability.
3.4¢ price + 1.0¢ spread + 0.2¢ 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.
