Odds & Liquidity Snapshot: Anthropic 98.4% on $7.33M Quantity as Google (0.8%) and OpenAI (0.3%) Keep Sub‑1%
This can be a multi-outcome Polymarket contract, so every consequence is its personal Sure/No wager on who will likely be judged “greatest” on the finish of July—not a single binary market. Even with $7,332,456 in quantity, pricing is extraordinarily top-heavy: Anthropic is 98.4% Sure / 1.6% No, whereas Google is 0.8% Sure / 99.2% No and OpenAI is 0.3% Sure / 99.7% No, leaving little implied likelihood mass for a late leaderboard shuffle.
