**Trader sentiment strongly favors "No" (94.5% implied probability) because Sam Altman has not signed the July 2026 "Pacing the Frontier" employee statement despite nearly two months of public discussion and repeated opportunities to do so.** The statement, hosted at pacingthefrontier.com and signed by over 1,300 verified employees from labs including OpenAI, Anthropic, Google DeepMind, and Meta, requests U.S. government support for international tools to deliberately slow automated AI research if capabilities outpace control and oversight. It emphasizes competitive pressures preventing unilateral slowdowns but stops short of calling for an immediate pause. Anthropic CEO Dario Amodei signed personally, along with senior OpenAI researchers such as Chief Scientist Jakub Pachocki and Chief Research Officer Mark Chen, yet Altman has remained absent from the list. Recent developments reinforce the market view. In mid-September 2026, Altman posted detailed support for "pacing the frontier" concepts—endorsing independent evaluators with employee-like access, safety cases ahead of major training runs, and international coordination—while stressing that pacing does not mean stopping progress and that OpenAI can act without waiting for antitrust exemptions. These statements align with industry talks on standards bodies but channel his views through company announcements and X posts rather than the employee petition. Historical precedent also matters: Altman previously declined similar 2023 slowdown letters over technical concerns, and the current document targets employee signatories verified via corporate email. With only 14 days remaining until September 30, a signature would require an abrupt shift in approach. While unexpected last-minute alignment or internal pressure could theoretically alter the outcome, the combination of Altman’s established preference for separate messaging, the statement’s employee focus, and sustained non-signature since July underpins the overwhelming trader consensus on "No."
