No measured edge, which here means a loss: the plain consensus (5+ holders, 60 %+, held to resolution) lost −3.0 % a trade after costs out of sample in the full-year test (n 86,296, 95 % CI −3.6 to −2.4 %).

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.
Consensus under 60 %Every backtest started at 60 %+ of the holders; below that nothing was measured.
Fewer than 5 holdersEvery backtest needed 5+ holders; with fewer nothing was measured.
Side priced 30–50¢Full year, out of sample: 0.30–0.50 lost −4.8 % a trade (n 16,830, 95 % CI −6.6 to −3.1), worse than the plain consensus.

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.

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.
