NVIDIA be the largest company in the world by market cap on December 31 priced at 64.0% on Polymarket, up 4.5 points, on $1.5M traded

NVIDIA’s chance of being the world’s largest company by market capitalization on December 31 was priced at 64.0% on Polymarket, up 4.5 probability points, with $1.5M traded, according to the supplied market update published Oct 25, 2026 · 10:54 PM ET.

A repricing without a fresh catalyst

The increase signals a stronger market assessment of NVIDIA’s prospects for the year-end ranking. The supplied news-search summary, however, identified no significant new platform headline in the preceding 30 minutes. It therefore provides no fresh reporting that explains the move.

According to predictionbubbles.net, its movers board compares probabilities over 24 hours using prices from Polymarket and Kalshi, with updates every 15 minutes. The supplied page records a venue-data snapshot of 26 Oct 2026, 02:36 UTC.

What the figures establish

Predictionbubbles.net ranks moves by their size in probability points, rather than by relative percentage change. NVIDIA’s reported gain of 4.5 points should be read on that basis—not as a 4.5% relative increase.

The $1.5M traded provides activity context, but the supplied headline does not specify its measurement period. Nor does the material give order-book depth or identify the trades behind the increase. Those omissions limit conclusions about what drove the repricing.

What it means for prediction markets

• The contract concerns a specific deadline: NVIDIA must hold the top market-cap position on December 31; the price is not a statement about its current ranking.
• Price movement is not a confirmed catalyst: The higher implied probability is observable, but the supplied reporting does not establish why traders revised it.
• Volume and liquidity are different measures: The reported $1.5M traded does not, by itself, show how much liquidity was available when the price moved.
