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. Otherwise, this market will resolve to "No." 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. The resolution source will be a consensus of credible reporting.
