Rules

This market resolves to “Yes” if a written diplomatic instrument between the United States and Iran that establishes a percentage cap of 5% or less on the purity level to which Iran may enrich uranium, committed to for at least one year, has been mutually signed or otherwise formally adopted by December 31, 2026, 11:59 PM ET. Otherwise, this market resolves to “No.”

The instrument must specifically include a 5% or lower percentage cap that operates as a general ceiling on the level to which Iran may enrich uranium for any purpose. Vague, or non-specific language regarding the level of Iranian uranium enrichment which does not establish a specific percentage cap on all Iranian enrichment (e.g., “lower levels”, “civilian grade”, “maintain the status quo”) will not qualify. Caps which directly mandate a precise 5% or lower percentage cap on Iranian enrichment through reference to a publicly-recognized benchmark percentage (e.g., JCPOA-levels), however, will qualify, even if they do not specifically reference the relevant numeric percentage itself. An Iranian commitment to end all enrichment of uranium qualifies as a cap, as it establishes a 0% cap on Iranian uranium enrichment.

A qualifying enrichment cap must be committed for a period of at least one year. A permanent enrichment cap will qualify. An enrichment cap with no specified end date will qualify unless explicitly framed as short-term, provisional, or temporary (e.g., a commitment not to enrich uranium while the exact implementation terms of the instrument are being finalized would not qualify). A cap committed to for less than one year will not qualify, even if framed as permitting extension.

The enrichment cap must be expressed as a presently-agreed obligation to be implemented. A presently-agreed obligation to such an enrichment cap will qualify, even if technical or procedural details, including the implementation schedule or specific monitoring requirements, remain subject to future arrangements.
