Polymarket’s contract on whether NVIDIA will be the largest company by market cap on July 31 saw its YES price fall by 18.0 percentage points in the last 24 hours, dropping from 81.5% to 63.5%. This significant repricing reflects a notable shift in market sentiment despite active whale participation that moved counter to the price trend.
Whales contributed $46K in net flow into YES positions during this period, with $90K in buy volume and $44K in sell volume, involving 157 unique whale traders. This buying pressure contrasts with the overall price decline, signaling a divergence between large investor activity and the broader market.
The total 24-hour volume on Polymarket for this contract reached $92K, representing a substantial fraction of the lifetime market volume of $1.40M, traded by a community of 3,038 unique traders. The divergence between whale flow and price indicates complex dynamics where large traders see value even as the market reassesses NVIDIA’s growth prospects.
This combination of a sharp 18pp drop in odds alongside $46K of whale buying suggests a nuanced market environment. While the crowd is lowering expectations for NVIDIA’s rank by July 31, significant whale activity implies some investors remain confident or are positioning for a potential reversal.
