Recent US policy explicitly exempts American open-weight large language models from pre-release government testing requirements under the June 2026 executive order and subsequent White House frameworks, while promoting their adoption to maintain competitive edge against Chinese alternatives. Targeted export controls have focused on closed proprietary systems from firms like Anthropic, with quick reversals, and proposed legislation such as the Open-Source AI Leadership Act reinforces support rather than restrictions. Trader consensus at 91% for no ban reflects these carve-outs and the absence of any outright prohibition through early September. A major demonstrated misuse incident or rapid capability gains by adversary open models could still prompt narrower interventions.
Experimental AI-generated summary referencing Polymarket data. This is not trading advice and plays no role in how this market resolves. · Updated“Open source AI model" refers to a general-purpose large language or multimodal foundation model whose weights and source are publicly downloadable and usable on user-controlled hardware (e.g., Llama, Mistral, DeepSeek, Qwen). "Source available" AI models will qualify regardless of any licensing restrictions on acceptable use. Narrow or special-purpose models (e.g., embedding, moderation, or single-modality media generation models) and deprecated, research-only, or preview-only models will not qualify.
To qualify, a ban must target ordinary public access to the model across ordinary public channels within the US. A ban with the intention to remove access from a single channel is not sufficient.
A qualifying ban may target a specific model or a slate of models, so long as at least one open source model is restricted.
A qualifying ban enacted or issued by the resolution date will qualify regardless of if or when it takes effect.
Both temporary bans, including those with a defined end date, and indefinite bans will qualify.
Non-binding or preliminary actions, including non-binding resolutions, recommendations, proposed or pending legislation, investigations, and hearings, will not qualify on their own.
The resolution source for this market is official information and announcements from the United States government and the maintainer or developer of the relevant open source AI model. However, a consensus of credible reporting may also be used.
