37% — the median of 6 frontier models, resolving by 2029-11-11.

Answer

Gemini (Google): 42% — FSIS rulemaking moves slowly, leaving only ~13 months before the 2028 deadline while an ANPR remains unadvanced to a final rule. USDA-FSIS has yet to publish a Notice of Proposed Rulemaking, and the standard federal notice-and-comment process takes 18-36 months. Conventional meat lobby pressure will maintain demand for clear labeling, but political turnover can easily delay or reset priorities. A published NPRM in early 2027 would push this probability above 70%, but continued case-by-case label approvals keeps urgency low.

Answer

Claude (Anthropic): 32% — Hinges on whether USDA/FSIS finishes a formal rulemaking on cultivated-meat labeling before the 2029-11-11 deadline. FSIS has issued guidance and voluntary labeling approvals (e.g., UPSIDE Foods, GOOD Meat) but hasn't launched mandatory rulemaking as of late 2026. Federal rulemaking (NPRM, comment period, final rule) typically takes 2-4+ years, and state-level bans/labeling laws may preempt or slow federal action. Political momentum exists given state pushback (Florida, Alabama bans) pressuring USDA to standardize, which could accelerate action if a draft rule emerges by 2027.

Answer

GPT (OpenAI): 58% — USDA must convert its 2021 cell-cultured-food labeling principles into a completed FSIS rule before 2028. FSIS has jurisdiction over cultivated meat labels, but a proposed rule, comment review, and OMB clearance usually take 2–4 years. USDA has already sought input and approved product labels case by case, making a rule more likely than in a wholly unstarted area. A formal FSIS proposed rule or a congressional labeling mandate by 2027 would materially raise the odds.

Answer

Grok (xAI): 35% — USDA FSIS must issue a proposed rule then a final one in the remaining 13 months. No proposed rule exists yet; typical FSIS labeling rulemaking needs 60-90 day comments plus 6-12 months to finalize. Base rate for novel-food labeling (bioengineered, imitation) is 2-4 years from ANPR; this sits below that given 2026 start. A mid-2027 NPRM would most raise odds; continued use of case-by-case approvals would kill it.

Answer

DeepSeek (DeepSeek): 22% — USDA has no statutory hook to mandate cultivated-meat labeling; that power sits with FDA unless Congress acts. USDA's FSIS labels only inspected livestock and poultry; cultivated cells fall outside its jurisdiction, so it cannot finalize such a rule alone. FDA holds the cell-cultured meat portfolio under the 2019 joint agreement, and it has issued only voluntary guidance, not mandatory rules. Congress would need to pass legislation granting USDA authority, and no such bill has advanced past committee as of late 2026.

Answer

Qwen (Alibaba): 38% — Turns on whether USDA-FSIS publishes a proposed rule soon enough for the comment-and-finalize cycle to close by Dec 2027. USDA-FSIS rulemaking on contentious labeling (COOL, 'natural') historically takes 3–5 years from ANPR to final rule; this track started ~2019 but no proposed rule is yet… The current USDA leadership is openly hostile to cultivated meat, creating political pressure to act, but OMB review and comment analysis alone typically consume 12–18… A development that would raise this sharply: a proposed rule published before mid-2026, which would make a late-2027 final rule plausible; without that, the timeline…
