Polymarket Puts Just 8% Odds on US Government Banning an Open Source AI Model by 2026

Polymarket · x · 2026-09-05

A new Polymarket market prices the odds that the US government formally bans an open source AI model before the end of 2026 at just 8%.

• The resolution criteria require federal legislation, an executive order, export controls, or similar formal action targeting publicly downloadable general-purpose models (Llama, Mistral, DeepSeek, Qwen); blocking a single channel or narrow-purpose models doesn't qualify.
• Context cited from the NYT: corporate America — including AT&T, Airbnb and Deloitte — is rapidly shifting toward open source AI for cheaper alternatives to OpenAI and Anthropic models.
• The market signal suggests an outright US ban on open model distribution remains a low-probability tail risk.
