The market on Polymarket for whether Apple will be the largest company in the world by market cap on July 31 saw a significant shift, with the YES contract price rising from 13.9% to 34.9%, a 20.9 percentage point increase in the past 24 hours.
This sharp repricing was accompanied by strong whale activity that confirmed the move rather than contradicted it. Whale traders executed $12K in buy volume against $5K in sells over the same period, resulting in a net $7K flow into YES. This alignment between price action and whale flow underscores growing confidence among large traders in Apple’s chances of claiming the top market cap spot.
The 24-hour volume on this market totaled $17K, a substantial portion of the lifetime market volume of $214K across 399 unique traders. The participation of 63 unique whales in the last day highlights concentrated interest from high-net-value participants driving this rapid market adjustment.
The combined surge in price and whale net buying suggests a notable shift in market sentiment on Apple’s position relative to its competitors by the end of July. The market is now pricing roughly one-third probability that Apple will be the largest company by that date, reflecting increased optimism or new information impacting expectations.
