NVIDIA be the largest company in the world by market cap on October 31, 2026 priced at 61.7% on Polymarket

NVIDIA’s market-cap contract moves higher

Polymarket priced the chance that NVIDIA would be the world’s largest company by market capitalization on October 31, 2026 at 61.7%, according to the supplied market snapshot published on Oct 25, 2026 at 12:39 AM ET. The probability was up 5.7 percentage points, with $258K traded.

The move signals stronger market confidence in a first-place finish for NVIDIA on the specified date. It is a price for that particular outcome, not a projection of NVIDIA’s market capitalization or share-price performance.

Reading the snapshot

According to predictionbubbles.net, its finance board reports probability changes over the preceding 24 hours and displays total traded volume where the venue provides it. The $258K figure therefore should not be read as the amount traded during the latest probability move.

PredictionBubbles aggregates prices from Polymarket and Kalshi and refreshes its data every 15 minutes, while trading on the venues continues between updates. The supplied material does not identify a catalyst for NVIDIA’s repricing or provide the contract’s detailed resolution rules.

What it means for prediction markets

• The outcome is favored, not settled: A 61.7% price puts NVIDIA above an even chance of holding the top market-cap position on October 31, 2026.
• Movement and volume measure different things: The 5.7-point increase captures a change in expectations; $258K represents total reported trading, not necessarily fresh activity behind that change.
• The exact contract matters: PredictionBubbles cautions that related markets can differ in wording, deadlines and resolution rules. Those details are necessary before treating another listing as directly comparable.
