74% — the median of 6 frontier models, resolving by 2027-10-17.

Answer

Gemini (Google): 73% — EPA deregs typically finalize unless derailed by judicial stays or major White House shifts. One year is sufficient time for EPA to conclude notice-and-comment and publish a final rescission in the Federal Register. The administration has strong political motivation and industry backing to eliminate third-party super-emitter monitoring. A procedural delay from voluminous public comments or sudden legal injunctions on underlying rule revisions could stall it.

Answer

Claude (Anthropic): 62% — Hinges on EPA completing notice-and-comment and surviving legal review before Oct 2027. EPA has already issued a proposed rule, so the main remaining steps are comment review, finalization, and possible litigation defense. Trump-era EPA has strong political will to deregulate methane rules, and a one-year window is plenty for a single rule finalization given past agency timelines. Litigation or a government shutdown/administrative delay could push finalization past the deadline, which is the main risk to this resolving yes.

Answer

GPT (OpenAI): 74% — EPA control and a full year make final rescission more likely than not, barring a court or policy reversal. EPA must close notice-and-comment, review significant comments, and publish a reasoned final rule in the Federal Register before October 2027. A year is usually enough for deregulatory EPA rules, though major Clean Air Act rules often draw delay and litigation. Odds would rise sharply if OMB clears the final rule by mid-2027; a court stay or administration shift would be the main spoiler.

Answer

Grok (xAI): 78% — EPA appointees finish OIRA review and comment response on a deregulatory priority. Administrator must sign the final by Oct 2027 after the already-open comment period and OIRA; no election intervenes. Trump-era EPA finalized most proposed oil-gas rollbacks within 12-18 months once proposed; this sits at that base rate. A court stay or midterm-driven pause would most shift odds, but neither blocks issuance itself.

Answer

DeepSeek (DeepSeek): 14% — EPA must publish a final rule in the Federal Register before Oct 2027; proposal alone doesn't count. EPA published the proposal in 2025 and has roughly 12 months left, but final rules routinely slip past a year after proposal. The Clean Air Act requires notice-and-comment; EPA must review comments, draft preamble, and clear OMB/OIRA review before signature. Congressional Review Act and litigation risk add delay, but EPA has strong political incentive to finish before the 2028 election cycle.

Answer

Qwen (Alibaba): 74% — One year is ample for finalizing a rescission already proposed; the main risk is procedural delay or reprioritization. Rescissions of existing programs typically finalize within 6–12 months of proposal since they require less technical justification than new rules. The Trump EPA has prioritized oil-and-gas deregulation and faces no congressional approval requirement, so the binding constraint is just comment review and OMB… A development that would lower this: a court stay on a related methane rule or an OIRA return letter forcing re-analysis, though neither is likely within this window.
