Eight Polymarket markets, one per candidate company, price the live odds that each finishes 2026 as the world's most valuable company. We read them all from Allium onchain data, pulled June 24, 2026.

Nvidia is the clear favorite at 74%, and has led since November 2025 with a single five-day exception in early February, when Alphabet crossed $4 trillion and briefly took the lead at 42%. The market nearly matches the real market-cap order, but it pays the leader far more than its size: Nvidia carries 74% of the odds on about 30% of the four leaders' combined value, roughly seven times its nearest rival on a real lead of just $600B.

The most counterintuitive read: from February to April, Nvidia's stock fell about 13% while its odds rose, because the market is pricing its lead over the field rather than its share price. Inside, we break down where the field stands, how the lead has changed hands, and what the onchain holder and concentration data can and cannot tell you.
