Best AI Model Leaderboard

Not just the nearest resolution date — every real period Polymarket runs this "single best AI model" contract for, combined with a real volume-weighted average that also discounts each period by how far out it resolves (a period backed by more real trading pulls the score toward it more, but a heavily-traded contract months away still can't fully outvote a thinly-traded one resolving imminently — the score stays anchored to who's actually favored right now). A lab genuinely closing on the leader fast — a real, rising 1-week change in the soonest tracked period — also gets a small, capped boost toward the leader before the blend runs, so a fast-moving real challenger doesn't score as far behind as a flat one sitting at the same raw probability; it can never fabricate a lead or overtake the real leader on trend alone. The period-by-period table below shows the same underlying real contracts broken out one date at a time, unadjusted.
