On Polymarket\u2019s \u201cWhich company has best AI model end of July?\u201d contract, traders still price Anthropic as the dominant favorite despite a recent dip in implied odds.<\/p>\n<h3>Key Takeaways<\/h3>\n<ul>\n<li>Polymarket prices Anthropic at 86.5% to have the best AI model at the end of July, versus Google at 11.1% and OpenAI at 2.5%.<\/li>\n<li>Traders are weighing policy and availability risk around Anthropic\u2019s top models while keeping the market heavily concentrated in the Anthropic outcome.<\/li>\n<li>The contract resolves on 2026-07-31, and the leading outcome\u2019s implied odds are down 2.5 points over the past 24 hours.<\/li>\n<\/ul>\n<p>Anthropic has kept its Mythos-class models offline for two weeks after a Friday evening ultimatum from the Trump administration, sending executives to Washington as talks dragged on without a clear resolution. The administration\u2019s June 12 export control order required Anthropic to suspend access by \u201cany foreign national\u201d to Mythos 5 and Fable 5 on security grounds, covering non-US citizens inside and outside the United States, including company employees. Anthropic has repeatedly declined to comment on the status of negotiations, and the report said it remains unclear when or whether the company\u2019s most powerful models will return. The standoff reflects a broader problem of applying export controls to AI systems without an established framework, a process that can take months or years for dual-use products. The report also described a claimed method of bypassing Fable 5 guardrails that was reviewed by security executive Katie Moussouris, who argued the issue was overstated and that the behavior is central to defensive security workflows.<\/p>\n<h2>Polymarket Odds and Volume: $1.92M Traded as Anthropic Holds 86.5% vs Google 11.1% and OpenAI 2.5% (Down 2.5 Points in 2<\/h2>\n<p>On Polymarket, the multi-outcome contract has $1,920,608 in volume and remains tightly skewed toward Anthropic, with Anthropic Yes at 86.5% and No at 13.5%. Google is a distant second at 11.1% Yes versus 88.9% No, while OpenAI sits at 2.5% Yes and 97.5% No. The long tail is priced as near-zero: xAI is 0.25% Yes and 99.75% No, and several others including Microsoft, Meta, Amazon, and Alibaba are marked around 0.15% Yes and 99.85% No. The latest pricing implies the market is treating any change at the top as a low-probability event, even after a 24-hour move of -2.5 percentage points in the leading outcome\u2019s odds.<\/p>\n<p>Traders will be watching whether the contract\u2019s implied odds continue to drift ahead of the 2026-07-31 resolution, and whether liquidity remains concentrated in Anthropic versus Google and OpenAI.<\/p>\n<h2>Beyond the AI Leaderboard: Other High-Volume Polymarket Contracts Traders Are Watching Today<\/h2>\n<p>Elsewhere on Polymarket, flow is spreading across fast-moving tech and headline-driven geopolitics, with 88.55% pricing on \u201cGPT-5.6 released by&#8230;?\u201d and a hefty $21,882,124 in volume on \u201cWhich company has best AI model end of June?\u201d (98.95% on Anthropic).
