Cultivated meat becomes widely available in major US grocery supermarkets before 2028.

Question

WillHappen.ai · Accepted Answer

4% — the median of 6 frontier models, resolving by 2029-10-08.

Answer

Gemini (Google): 4% — Bioreactor scaling bottlenecks and high media costs make retail parity impossible across national supermarket chains by late 2027. UPSIDE Foods and GOOD Meat still produce at boutique batch scales, years away from the megaton output required for retail shelves. State-level bans enacted in Florida and Alabama create fragmented distribution barriers even if federal USDA/FDA approval holds. A tenfold drop in serum-free growth factor costs could accelerate pilot retail trials, but building commercial plants takes years.

Answer

Claude (Anthropic): 4% — Hinges on cultivated meat firms solving cost/scale bottlenecks for mass retail within ~3 years, which remains far off. Current players (Upside Foods, Good Meat) sell only to a handful of restaurants; retail-scale bioreactor capacity doesn't exist yet. Production costs remain far above conventional meat, and multiple state bans (Florida, Alabama, etc.) create regulatory headwinds in the US market. Base rate for novel food categories reaching 'wide' supermarket availability within 3 years of restaurant-only status is very low; no major grocery chain has announced…

Answer

GPT (OpenAI): 24% — Retail-scale production economics and supermarket chain adoption, not federal approval, are the binding constraints. USDA cleared UPSIDE and GOOD Meat poultry in 2023, but both began with limited restaurant launches rather than grocery rollout. By 2028, firms must build reliable high-volume facilities, win retailer listings, and reach tolerable prices; this usually takes years. Probability rises sharply if a national chain announces multi-region listings backed by a commissioned commercial-scale plant by 2027.

Answer

Grok (xAI): 12% — Massive production scale-up plus major-chain deals must close in under 15 months. UPSIDE, GOOD Meat and peers must finish commercial bioreactors and lock Kroger/Walmart contracts by late 2027. Zero grocery SKUs exist today; plant-based meat needed 3–5 years after restaurant launch, and cultivated faces far steeper cost/scale barriers. FL/AL bans plus retailer caution would reverse only on a national chain announcing nationwide distribution.

Answer

DeepSeek (DeepSeek): 3% — Cost per pound must fall roughly 100x and FDA/USDA labels clear for retail before any major chain stocks it. Upside Foods and Good Meat got USDA clearance in June 2023 but only for restaurant plates, not retail packaging. No US plant has demonstrated >100,000 lb/yr output; current cost is hundreds of dollars per pound versus $5 beef. Kroger, Walmart, and Albertsons would need months of supplier qualification and labeling review before shelf placement.

Answer

Qwen (Alibaba): 3% — Cost parity with conventional meat is still years away; no cultivated meat company has announced retail distribution deals with major US chains. As of late 2025, cultivated meat costs remain 5–20× conventional protein at scale; no company has reached price parity needed for grocery shelf competition. Major chains (Kroger, Walmart, Albertsons) have made zero announcements of cultivated meat retail placement; getting shelf space requires volume commitments and consumer… Even optimistic industry roadmaps (Good Food Institute, McKinsey) project meaningful retail presence no earlier than 2030–2032, and those assume faster scaling than…
