Research grade
NeutralNo at 72%
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 %).
- Consensus under 60 %Every backtest started at 60 %+ of the holders; below that nothing was measured.
- Favourite (60–95¢)Full year, out of sample: 0.70–0.90 lost −0.9 % a trade (n 26,050, 95 % CI −1.5 to −0.3): the least bad band, still a loss. The Oct 22 backtest's +0.4 % (n 4,327) was not confirmed.
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.

EV Calculator
Consensus % is how many tracked traders hold a side, not a win probability.
72.0¢ price + 1.0¢ spread + 0.8¢ fee (Tech 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.
