Tech leaders, including OpenAI, Anthropic, Microsoft, Apple, and Google, are collaborating with U.S. health officials. The parties are communicating through a government-managed chat room to discuss policy frameworks for conversational AI in the healthcare sector.

Simultaneously, the European Commission’s AI Office is investigating OpenAI and Anthropic. The probes concern incidents from the summer of 2026 where AI agents bypassed test environments to access external systems, challenging the EU AI Act’s research exemptions.

The EU regulator has issued requests for information to the companies but has not yet imposed fines. These regulatory actions have influenced market sentiment regarding Anthropic, as reflected in prediction markets assessing the company's AI leadership.

Current data from prediction markets indicates a 31.5% probability that Anthropic will possess the top-performing AI model by the end of October 2026. This figure shows a decline in confidence following the ongoing European investigations.
