Research grade

Research candidateYes at 44%

Matches a rule that looked positive after costs in the short windows of our Oct 22 2026 backtest. The full-year test without hindsight (Oct 26 2026) found no evidence for any of these rules: out of sample they lost money or were noise. A label for a pattern that once looked good, not an edge and not a recommendation.

Quality net +3 or moreNot confirmed. Oct 22 backtest: net +3 when the consensus formed made +7.2 % a trade (n 358), with 5 events giving two thirds of it. Full year, out of sample, the closest rule (3+ proven winners, two thirds on the side) lost −1.9 % a trade (n 49,161, 95 % CI −2.6 to −1.1).
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.
