- Lisa Murkowski leaves the Republican Party in 2026?12¢12%
Sen. Lisa Murkowski remains a Republican member of the U.S. Senate from Alaska with her current term extending through January 2029. Recent reporting from mid-October 2026 highlights her anticipated rise in Senate GOP committee leadership on panels such as Health, Education, Labor and Pensions or Appropriations, reflecting institutional positioning within the party rather than any move toward independence. Official records and voting tallies continue to list her as Republican, with participation in majority roll calls and no public statements or filings signaling a party switch by year-end. Earlier 2025 comments about hypothetical independent caucusing were followed by her explicit rejection of a full party change, and no comparable developments have emerged in 2026 to alter that stance. Traders’ 93% probability on “No” aligns with this continuity in her official affiliation and Senate role.
Rules
This market will resolve to “Yes” if Lisa Murkowski leaves, or announces that she is leaving, the Republican Party by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. An official announcement from Murkowski that she will leave the Republican Party, join a separate party, or become an independent within this market’s timeframe will be sufficient to resolve this market to “Yes”, regardless of when the announced party switch is intended to take effect or whether Murkowski intends to continue caucusing with the Republican Party. The primary resolution source for this market will be official information from Lisa Murkowski; however, a consensus of credible reporting may also be used.
