Best AI model: Polymarket widens Google's lead to 73% over Anthropic at 27% for end-October

Google leads the Polymarket market on which company will have the best AI model at the end of October, but the supplied readings differ. The headline published Oct. 13, 2026, at 2:39 PM ET puts Google at 73% and Anthropic at 27%; the accompanying DeFi Rate page lists them at 72% and 23%, respectively.

Google leads across both readings

According to DeFi Rate’s snapshot, observed Oct. 13 between 9:09 AM and 2:13 PM ET, Google traded at 73c. The snapshot recorded $22K in 24-hour volume, with Google the most-traded outcome at $11K.

The supplied DeFi Rate page reports that Google made the largest gain over the past week on Polymarket, rising 5 points to 72%. Anthropic fell 7 points to 23%. The summary also describes a 5-point increase for Google, although its truncated text does not identify the comparison period.

DeFi Rate additionally lists an ask-price illustration: a $100 purchase on Polymarket would return $137 if correct, before fees. That is the payout shown in the supplied material, rather than a separately verified current quote.

What it means for prediction markets

• The direction is consistent, the exact spread is not. Both readings favor Google, but the headline’s 73%–27% split differs from the page’s 72%–23% figures. They should not be treated as one synchronized quote.
• Trading was concentrated in Google. Its $11K in 24-hour volume accounted for half of the snapshot’s $22K total.
• These are market expectations, not a technical verdict. The supplied material does not specify the benchmark or resolution criteria for determining the best AI model at the end of October.
