**Jacob Coxon, a former Anthropic and OpenAI researcher, resigned in early September 2026 and posted a viral warning on X that AI companies are racing toward self-improving superintelligence, with many insiders privately believing it could pose an existential risk to humanity by the end of the decade.** His statements drew immediate bipartisan attention on Capitol Hill, prompting calls from figures including Sen. Bernie Sanders for briefings and potential legislation to pause or regulate advanced AI development, alongside statements from other lawmakers urging hearings or a special session. No public hearing with Coxon has been formally scheduled or announced as of mid-September 2026. Congressional committees move deliberately, and the short window to October 31 overlaps with competing legislative priorities, potential partisan divides over the scope of any AI oversight, and procedural steps such as committee approvals and witness coordination. While the episode has accelerated discussion of AI safety and prompted references to future investigations or select committees, trader consensus at 59.5% for “No” reflects the absence of confirmed public testimony plans and the typical lead time required for such appearances.
