15% — the median of 6 frontier models, resolving by 2029-09-22.

Answer

Gemini (Google): 8% — Scaling bioreactor capacity and cutting media costs to compete on retail margins cannot happen within 15 months. UPSIDE Foods and GOOD Meat remain trapped in pilot-scale volumes, incapable of supplying national footprints like Kroger or Walmart. State bans in Florida and Alabama plus federal labeling hurdles make major retail chains hesitant to allocate valuable shelf space. A massive, low-percentage blended hybrid meat pilot contract announced with a top grocer by early 2027 would rapidly lift these odds.

Answer

Claude (Anthropic): 8% — Whether cultivated meat producers can scale production costs low enough for retail while navigating state bans by 2029. Only two US firms (Upside Foods, Good Meat) have federal approval, and both remain restaurant-only with tiny production volumes as of 2026. Multiple states (Florida, Alabama, Mississippi, others) have banned cultivated meat sales, complicating any national retail rollout strategy. Cost-per-pound for cultivated meat still far exceeds conventional meat, and scaling bioreactor capacity to retail volumes typically takes 5-10+ years.

Answer

GPT (OpenAI): 63% — The key hinge is whether at least one approved producer can scale cheaply enough for a national grocer to risk a limited launch by 2029. USDA already granted 2023 poultry inspection labels to UPSIDE and GOOD Meat, so federal retail authorization has precedent. A national-chain listing needs reliable inspected production, cold-chain supply, pricing, and retailer acceptance; these usually take years after approval. This rises sharply if UPSIDE, GOOD Meat, or a well-funded entrant announces a 2027–28 supermarket pilot with a major chain.

Answer

Grok (xAI): 22% — Retail stocking by end-2027 hinges on a producer hitting supermarket-scale output and a national chain signing a supply deal. Upside, GOOD Meat and peers must commission multi-ton facilities and lock Kroger/Walmart-level volume contracts in 2027; none have done so yet. Plant-based meats reached grocery 3–4 years after restaurant launch, but cultivated meat’s bioreactor costs and yields sit well below that precedent. A public 2027 offtake announcement from a top-5 grocer plus a USDA-inspected plant coming online would raise the odds sharply.

Answer

DeepSeek (DeepSeek): 8% — This turns on whether UPSIDE or GOOD Meat can cut cost per pound below conventional chicken and clear USDA retail labeling before 2028. UPSIDE Foods' 2024 Emeryville plant pause and GOOD Meat's 2023 Singapore-only retail pilot show no US grocery-scale capacity exists today. USDA/FDA cleared cultivated chicken in June 2023, but retail needs per-pound costs near $5 versus current estimates above $50, a gap no firm has closed. Base rate for novel food categories reaching national grocery within five years of approval is low; Impossible Foods took seven years from 2011 launch to 2019 Burger…

Answer

Qwen (Alibaba): 27% — Scaling cost and production volume must drop enough to make retail economics work within ~3 years. Upside Foods and Good Meat have repeatedly delayed scale-up targets; neither has announced a retail partnership with a national chain as of mid-2026. Cultivated meat still costs roughly $10-30/lb to produce vs. $3-5/lb for conventional chicken, making shelf pricing uncompetitive without massive subsidies. A single deal with Kroger, Walmart, or Albertsons would shift this sharply upward, but no public signals suggest one is imminent.
