For the purposes of this market, “to introduce a domestic restriction on open-weight LLMs” means new federal action that removes or limits US citizens’ ability to develop, access, use, or modify one or more open-weight LLMs. “New” is relative to this market’s creation on June 13, 2026.

I will resolve to YES if, by the end of 2026, this occurs, is publicly reported, and is documented on this market. I will resolve to NO at the close of the market otherwise.
