   NRC issues initial COL by deadline ↑ 0 ↓ 2 direct

   By Dec 31, 2026 11:59 PM ET, the U.S. NRC issues an initial combined license (COL) to construct and operate a nuclear power plant, in an official NRC release. No amendments/renewals/partials.

Carver Signal Narrative

Since March 2026, multistate AGs led by California AG Bonta oppose federal efforts to exempt new/experimental reactors from environmental review, creating legal and political headwinds that could delay NRC combined-license approvals this year. Other listed items (Ontario securities rule and CA oil-pipeline case) are unrelated and don’t affect odds. NRC licensing timelines and any court outcomes on the exemptions remain pending.

   Attorney General Bonta Seeks to Halt Trump Administration’s Illegal Greenlight of Oil Transportation - May 1, 2026

   California AG's opposition to federal exemptions could block expedited reviews and make an NRC COL by end-2026 less likely.

Resolution criteria

This market will resolve to 'Yes' if the U.S. Nuclear Regulatory Commission (NRC) issues a new combined license (COL) for the construction and operation of a nuclear power plant by December 31, 2026, 11:59 PM ET. A combined license must be clearly identified as such and documented in official NRC releases. Only initial issuances count; amendments, renewals, or partial approvals do not qualify. Note: In March 2026, TerraPower's Natrium sodium-cooled advanced reactor received its first commercial construction permit — the first non-light-water reactor permit in years — but a separate combined operating license (COL) application remains pending. This market resolves on the full COL issuance, not the construction permit.
