Polymarket’s prediction that NVIDIA will be the largest company in the world by market cap on July 31 saw its YES contract price fall sharply by 18.0 percentage points in the past 24 hours, dropping from 76.0% to 58.0% as of the July 17 snapshot. This significant decline in market-implied probability signals a notable shift in trader sentiment or new information influencing the broader market.
Contrary to the price movement, whale activity diverged from the tape, with large traders increasing their net exposure to YES by $40K over the same period. Whale buy volume totaled $80K, against $40K in sells, across 154 unique whales. This divergence between price and whale flow indicates that while the crowd trimmed optimism on NVIDIA’s market cap dominance, substantial whale interest remained or even grew.
Overall 24-hour volume on this market reached $84K, contributing to a lifetime market volume of $1.41M and involving 3,069 unique traders.
This combination of a sharp price decline alongside increasing whale YES bets points to a contested market narrative around NVIDIA’s prospects as the largest company by July 31, highlighting divergent views among retail and large-scale traders alike.
