AvoidGrizzlies at 55%

Matches a pattern that lost clearly more than the plain consensus in our tests.

  • BasketballFull year, out of sample: basketball lost −4.8 % a trade (n 1,747, 95 % CI −9.2 to +0.3); Oct 22 backtest: −12.0 % and −9.2 % in its two windows.
  • 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.
  • Side priced 50–60¢Full year, out of sample: 0.50–0.70 lost −2.9 % a trade (n 23,546, 95 % CI −3.9 to −1.9).

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.
