About This Event
This market will resolve to “Yes” if the US federal government passes legislation, issues an executive order, issues an export control, or takes any other formal action with the intent to ban distribution to, access for, or use of an open source AI model by the general public within the US, between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market resolves "No". “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.
This analysis is awaiting a background update, so its prices may be older than the odds above.

What the contract measures
The contract asks whether a US federal action will restrict public access to an open source AI model during a defined window. Under the rules, it resolves "Yes" if the US federal government passes legislation, issues an executive order, issues an export control, or takes any other formal action with the intent to ban distribution to, access for, or use of an open source AI model by the general public within the US [1]. The rules count a ban whether it is temporary or indefinite, and whether or not it has taken effect, provided it is enacted or issued by the resolution date [1]. Non-binding steps such as hearings, investigations, and proposed or pending legislation do not qualify on their own [1].
The rules also define "open source AI model" narrowly, covering general-purpose large language or multimodal foundation models whose weights and source are publicly downloadable [1]. A ban on a single channel is not sufficient [1]. The listed end time is 2027-01-01T04:59:00.000Z, which corresponds to the December 31, 2026, 11:59 PM ET wording in the rules [1].
Reading the snapshot
The saved provider observation is dated 2026-10-19T00:00:05.826Z, and the evidence was retrieved at 2026-10-19T02:27:54.469Z [1]. This is a record of that moment, not a live reading. The single saved market shows a Yes price of 0.055 and a No price of 0.945 [1]. These are snapshot prices, not executable quotes, and they should not be read as verified probabilities. The volume and trader activity behind them are not part of the evidence.
The sample includes the one saved market for this event, and the coverage record marks it as complete for the saved event, not partial [1]. That description applies only to the provider event saved here. It does not establish that the providers list every possible real-world outcome.
What remains uncertain
The evidence does not explain why the price sits where it does, and it contains no recent news about federal action on open source models. It also does not establish how many traders hold either position. Because this is one contract on one platform, there is no comparison to draw with other platforms or other wordings. Differences in close times or resolution language between any future contracts would need to be checked against their own rules before comparing prices.

Overview
This market asks whether the US federal government will take a formal action that bans an open source AI model from public use in the country during 2026. According to the contract rules, it resolves "Yes" if the federal government passes legislation, issues an executive order, issues an export control, or takes another formal action intended to ban distribution to, access for, or use of an open source AI model by the general public within the US. The window runs from market creation until December 31, 2026, 11:59 PM ET, and the listed end time is 2027-01-01T04:59:00.000Z [1]. Otherwise the market resolves "No" [1]. The rules define an open source AI model as a general-purpose large language or multimodal foundation model whose weights and source code are publicly downloadable and usable on user-controlled hardware. The rules give Llama, Mistral, DeepSeek, and Qwen as examples [1]. Source available models qualify regardless of licensing restrictions on acceptable use [1]. Narrow or special-purpose models, such as embedding, moderation, or single-modality media generation models, do not qualify. Neither do deprecated, research-only, or preview-only models [1]. The rules also set limits on what counts as a ban. The action must target ordinary public access to the model across ordinary public channels within the US. A measure aimed at removing access from a single channel is not sufficient [1]. A qualifying ban may cover a specific model or a group of models, as long as at least one open source model is restricted [1]. A ban enacted or issued by the resolution date qualifies even if it takes effect later [1]. Both temporary bans, including those with a set end date, and indefinite bans qualify [1]. Non-binding or preliminary steps do not qualify on their own. These include non-binding resolutions, recommendations, proposed or pending legislation, investigations, and hearings [1]. The resolution source is official information and announcements from the US government and from the maintainer or developer of the relevant model. The rules also allow a consensus of credible reporting to be used [1].
Why It Matters
The contract measures whether a formal government action restricting public access to widely available open source AI models occurs before the end of 2026. The definitions are narrow. The contract covers general-purpose foundation models with publicly downloadable weights, and it excludes narrow tools, research-only releases, and actions that only remove access through one channel [1]. Because proposals, hearings, and investigations do not count alone, the contract separates formal government action from policy discussion [1]. Its resolution language also distinguishes an action's enactment date from its effective date, so a measure issued before the deadline could resolve the market even if it takes effect later [1].

Frequently Asked Questions
Does a bill being introduced in Congress resolve this market?
No, not on its own. The rules state that non-binding or preliminary actions, including proposed or pending legislation, investigations, and hearings, will not qualify on their own [1]. The qualifying action must be legislation that passes, an executive order, an export control, or another formal action intended to ban public access [1].
Would a ban on only one distribution channel count?
No. The rules say a ban must target ordinary public access across ordinary public channels within the US, and that a ban intended to remove access from a single channel is not sufficient [1].
Does a temporary ban qualify?
Yes. The rules state that both temporary bans, including those with a defined end date, and indefinite bans will qualify [1].
Does the ban have to take effect before the deadline?
No. The rules state that a qualifying ban enacted or issued by the resolution date will qualify regardless of if or when it takes effect [1].
Which models are considered open source for this contract?
The rules define qualifying models as general-purpose large language or multimodal foundation models with publicly downloadable weights and source that can be used on user-controlled hardware, and they name Llama, Mistral, DeepSeek, and Qwen as examples [1]. Narrow, deprecated, research-only, and preview-only models do not qualify [1].
