The probability that Apple will be the largest company in the world by market cap on July 31 surged 30.6 percentage points in the last 24 hours on Polymarket, climbing from 11.4% to 42.1%. This significant repricing reflects a notable shift in market expectations within a single day.
Whale activity aligned with the price move, as 66 unique whales contributed a net $8K inflow into YES contracts. Whale buy volume over the period was $16K, double the $8K in sell volume, indicating concentrated buying interest from larger traders. Total 24-hour trading volume in this market reached $21K, representing a meaningful portion of the market’s $218K lifetime volume and involving 410 unique traders overall.
This coordinated rise in the YES price alongside whale buying suggests growing conviction or new information influencing market participants to reassess Apple’s chances of maintaining the top market capitalization spot by the end of July. The combined flow and price action signals a material change in sentiment rather than isolated speculative bets, highlighting the market’s responsiveness to underlying fundamentals or external developments.
