Largest Company end of October: NVIDIA at 85% on Polymarket, Apple at 13%

NVIDIA leads, but the supplied readings differ

NVIDIA is priced at 85% and Apple at 13% in the supplied Oct. 16, 2026 · 2:54 AM ET snapshot of Polymarket’s market on the largest company at the end of October. The nine-outcome market places NVIDIA well ahead of its closest rival.

There is a discrepancy in the supplied material: the accompanying commentary from polymarket.com gives NVIDIA a 64% implied probability of finishing October 2026 in first place. That figure differs from the headline snapshot, and the material does not establish when the commentary’s probability was recorded.

Market-cap advantage underpins the lead

According to Polymarket’s commentary, NVIDIA has roughly $5.3 trillion in market capitalization, compared with Apple’s approximately $5.0 trillion. The commentary attributes NVIDIA’s substantial revenue growth to continuing demand for AI accelerators and data-center GPUs. It says the valuation gap has widened despite recent share-price volatility and Apple’s crossing of the $5 trillion threshold.

With only two weeks remaining, Polymarket’s commentary portrays the ranking as relatively stable, citing NVIDIA’s AI leadership and Apple’s more constrained opportunity to overtake it. Earnings surprises or macroeconomic changes are identified as possible forces that could shift the standings. Alphabet, Microsoft and the other contenders carry much lower odds, according to the same commentary.

What it means for prediction markets

• The latest supplied snapshot favors NVIDIA more strongly. Its 85% reading compares with 79% carried Oct. 15, while Apple’s 13% compares with 23%. That movement supports the picture of a widening market lead.
• Probability and valuation are separate measures. NVIDIA’s roughly $5.3 trillion capitalization puts it ahead of Apple at approximately $5.0 trillion; the contract prices express expectations about the end-of-October ranking.
• The probability discrepancy matters. The 64% figure in Polymarket’s commentary should not be treated as interchangeable with the 85% headline snapshot. The supplied material does not resolve their timing.
• The remaining window is short. The source identifies earnings surprises and macroeconomic shifts as potential ranking-changing developments, while assigning substantially less weight to challengers beyond Apple.
