Polymarket: Anthropic tops best AI model odds at 95.5% on $6.26M volume

Polymarket Reprices the “Best AI Model by July-End” Race After Hassabis Pushes a US-Led AI Watchdog

Polymarket traders are pricing Anthropic as the clear favorite to have the “best AI model” by end of July, with Anthropic leading at 95.5% on $6,259,514 in volume. The pricing comes as Google DeepMind CEO Demis Hassabis renewed calls for a US-led global AI watchdog, offering a live read on how the market ranks labs despite the broader governance debate.

Key Takeaways

• Prediction: Anthropic leads the multi-outcome Polymarket at 95.5% to have the best AI model by end of July (Google 4.35%, OpenAI 0.65%).
• Basis: Despite the governance-focused Hassabis catalyst, traders keep the “best model” race priced as a near-lock for Anthropic, with the rest of the field heavily discounted.
• Timing: The market resolves on 2026-07-31; recent pricing is choppy with historical_summary showing -2.5pp over both 24h and 7d and latest odds at 84.0.

Google DeepMind CEO Demis Hassabis argued for a US-led global AI watchdog that could evaluate frontier models before release and coordinate an industry-wide slowdown if systems are judged too risky. He said he hopes the institution could be running before year-end and described building support across government and AI labs.

Odds & Liquidity Snapshot: Anthropic 95.5% on $6.26M Volume vs Google 4.35% and OpenAI 0.65% (Latest 84.0, -2.5pp 24h/7d

This is a multi-outcome Polymarket, so each outcome is its own Yes/No contract on who will be judged “best AI model” at resolution, rather than a single binary. At the current snapshot, Anthropic trades at 95.5% Yes / 4.5% No, while Google sits at 4.35% Yes / 95.65% No and OpenAI at 0.65% Yes / 99.35% No, signaling a highly concentrated consensus rather than a tight three-way race. The market has attracted $6,259,514 in volume, yet the historical summary flags weakening consensus: latest odds are 84.0 versus an average of 93.2 over the last five readings, with -2.5pp over both 24 hours and seven days and moderate volatility. That combination suggests traders have been willing to pay up for the leader but are still actively rechecking the edge case where “best model” judgment could flip, which is exactly what continuously traded markets surface faster than slower narrative-driven rankings. The settlement clock is fixed to 2026-07-31, so any repricing will be about which lab is expected to look strongest on that specific end-of-month snapshot, not about general AI regulation momentum.

Watch whether the leader’s price stabilizes back near its recent average (93.2) or continues to drift toward the historical latest reading (84.0), and whether any challenger meaningfully lifts off single digits ahead of the 2026-07-31 resolution.

Cross-Market Watchlist: How “Best AI Model” Pricing Connects to Polymarket AI Governance, Big Tech, and Crypto-AI Contra

Beyond the “best AI model” tape, Polymarket traders are also cross-checking sentiment in adjacent, high-liquidity contracts where risk appetite can spill over into AI narratives. One to watch this week is 65.5% on “What price will Bitcoin hit July 13-19?” (leading outcome “↑ 64,000”) on $319,178 in volume, up +7.0pp—an example of how crypto momentum markets can become a real-time barometer for broader speculative positioning across the platform.
