Trader consensus favoring "No" on a new joint pacing agreement in 2026 stems primarily from the September 2026 "We Must Pace the Frontier" essay by Anthropic's Dario Amodei and the subsequent voluntary White House Accord signed September 29. These steps secured public endorsements from OpenAI's Sam Altman, xAI's Elon Musk, and Google DeepMind's Demis Hassabis on embedded third-party evaluators and safety standards, yet produced only non-binding commitments without enforceable limits on model capability gains. Antitrust litigation and the absence of named evaluators or implementation timelines as of early October underscore the gap between statements and coordinated slowdowns. With just weeks remaining and labs prioritizing competitive releases, the market-implied odds reflect skepticism that a formal, verifiable pacing pact will materialize before year-end.
