Polymarket and Kalshi odds diverge on Google vs Anthropic for 2026 top AI model
Polymarket and Kalshi prediction markets are showing conflicting odds on whether Google or Anthropic will produce the best AI model of 2026. Polymarket traders price Google at 43%, while Kalshi traders price Anthropic at 41%, according to data from Shattered.io. The divergence highlights how sentiment can vary across platforms even on the same underlying question. Separately, Polymarket traders are pricing a 40% probability that Anthropic will pause its AI training by the end of October, according to a post by Polymarket's official account on X.
Split odds on identical questions expose a real arbitrage problem for cross-platform traders. No mechanism exists to converge Google-Anthropic prices across venues, so a trader long Google at Polymarket and short Anthropic at Kalshi cannot safely lock a spread without basis risk. Platform operators now face competitive pressure to explain why their consensus differs.
The divergence also tests whether tech event contracts attract enough liquidity to produce stable prices, or whether thin books amplify noise. Related coverage shows AI odds have already shifted once recently. Traders must decide if the current split reflects genuine information asymmetry or simply low participation.
