The market on whether Anthropic will have the best Math AI model at the end of July 2026 saw its YES contract price plunge 31.5 percentage points in the last 24 hours, dropping from 68.5% to 37.0% according to Polymarket Breaking data. This dramatic repricing reflects a significant shift in market sentiment against Anthropic’s chances within a single day.
Contrary to the sharp price decline, whale flow diverged from the tape: large traders bought a net $3K worth of YES contracts, with $6K in buy volume versus $3K in sells over the same period. Forty-four unique whales participated in these trades, while total 24-hour Polymarket volume reached $9K. The lifetime market volume stands at $54K with 323 unique traders, indicating a relatively active and diverse participation.
Notably, the Polymarket Breaking YES price of 37.0% contrasts with the Polydata on-chain mid-price of 54.0%, highlighting a discrepancy between the live market and aggregated on-chain data. This divergence between whale buying and declining prices suggests conflicting views among large traders versus the broader market, possibly reflecting uncertainty or differing strategies about Anthropic’s competitive position in Math AI by mid-2026.
The combination of a steep price drop and whale buying indicates a complex market dynamic where large players are increasing exposure even as general sentiment turns more pessimistic.
