Nvidia’s market cap hit $5 trillion, and the Polymarket contract for Nvidia to be the largest company by April 30 is at 99.6% YES.

The June 30 market sits at 92.0% YES for Nvidia holding the top spot, while the April 30 market at 99.6% is priced as near-certain. The second-largest market for April 30, which would require Nvidia to slip a spot, sits at just 0.5% YES. With six days until resolution, traders are pricing almost no chance of Nvidia losing its lead.

The April 30 market has $46,745 in daily USDC volume and requires $183,166 to move the price by 5 points. That depth signals strong conviction, not thin speculation.

A YES share at 99.6¢ pays $1, a 1.004x return. The real action is in the June 30 contract, where the 8-point gap from certainty leaves more room for price movement if Nvidia’s stock pulls back or a competitor closes the gap.

Watch for Nvidia’s Q2 earnings announcements and any major AI contracts. Jensen Huang’s statements at upcoming tech conferences could also move these markets.
