The probability that NVIDIA will be the largest company in the world by market cap on July 31 plunged 38.0 percentage points over the past 24 hours, sliding from 84.5% to 46.5% on Polymarket. This sharp decline in the YES contract’s price contrasts with whale activity, which showed a net inflow of $42K into YES positions during the same period.
Whales traded actively, with $81K in buy volume and $40K in sell volume, involving 140 unique large traders. Despite the overall market price retreat, these whales increased their exposure to the YES outcome, creating a divergence between the price move and whale flow.
The total 24-hour volume on Polymarket for this market was $87K, a figure closely aligned with whale trading activity, which accounts for a substantial portion of the day’s trades. Since inception, the market has seen $1.39M in lifetime volume and attracted 2,979 unique traders.
This split—where the price sharply reprices lower while whales accumulate YES contracts—suggests differing interpretations between retail and large-scale traders about NVIDIA’s prospects to claim the top market cap spot by the end of July.
