NVIDIA be the largest company in the world by market cap on October 31, 2026 priced at 76.4% on Polymarket

Polymarket priced NVIDIA’s chances of being the world’s largest company by market capitalization on October 31, 2026 at 76.4%, according to the supplied market update published Oct 23, 2026 at 3:54 PM ET. The probability rose 9.7 points, with $239K traded.

The move reflects a higher market-implied likelihood of NVIDIA taking the top spot on the specified date. It does not establish NVIDIA’s current market-cap ranking or identify what prompted traders to revise their expectations.

Reading the repricing

According to predictionbubbles.net, its movers board measures changes over 24 hours using probability points rather than relative percentage gains. On that basis, the NVIDIA update represents a 9.7-percentage-point increase—not a 9.7% relative rise.

The site refreshes its data every 15 minutes using prices from Polymarket and Kalshi. The supplied source records a venue snapshot taken on 23 Oct 2026 at 19:41 UTC. Its rankings depend on the size of probability changes, while trading volume provides separate context.

What the figures leave unresolved

The $239K traded helps describe activity accompanying the move, but the supplied material gives no order-book depth, competing companies’ valuations or NVIDIA-specific news catalyst. Those gaps limit what can be concluded about the reasons for the repricing or its durability.

The contract concerns a market-cap ranking on October 31, 2026, rather than a standalone NVIDIA share-price target. The available update therefore captures traders’ expectations about that outcome, not evidence that it has already been secured.

What it means for prediction markets

• A stronger market favorite: The 76.4% price puts NVIDIA’s specified outcome above an even chance, while leaving uncertainty.
• Movement and activity are different measures: The 9.7-point rise describes the shift in expectations; $239K traded describes activity, not available liquidity.
• The catalyst remains unverified: The provided material documents a repricing but does not explain it or supply the contract’s detailed resolution rules.
