Recent announcements from Anthropic and OpenAI in mid-September 2026, including Anthropic's contract with Accenture's Faculty for embedded evaluators with employee-level access and OpenAI's published principles for ongoing third-party safety assessments, established the benchmark for "vetting" in this market. The late-September White House Accord on Super Intelligence, signed by Google, Meta, xAI, Nvidia and others, added voluntary pledges for independent external auditors alongside internal controls, though specifics on permanent embedded access remain undefined and may not satisfy resolution criteria. Competitive dynamics center on frontier labs aligning with safety signaling amid regulatory momentum in California and federal proposals, while xAI and Microsoft show moderate market-implied odds reflecting Musk's and Altman's prior support. With the October 31 deadline approaching, any new formal commitments on training-process access could shift trader consensus before resolution.
