Resolution criteria on PolyGram: 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.

Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Lisa Murkowski leaves the Republican Party in 2026? | 18% YES | 82% NO |
Lisa Murkowski, Alaska's senior senator and one of the Republican Party's most independent-minded members, could announce a departure from the GOP by the end of 2026. The 18% implied probability on Polymarket's order book reflects a relatively low but non-negligible expectation of such a move within the next two years. Murkowski has a documented history of defying party orthodoxy—most notably voting to convict Donald Trump during his second impeachment trial in 2021—and has previously considered leaving the party. Her 2022 re-election campaign saw her run as a write-in candidate after losing the Republican primary to Trump-endorsed Kelly Tshibaka, suggesting her relationship with the party establishment remains fractious.
Historical precedent offers mixed signals for interpreting this probability. Senators who have switched parties mid-term remain rare; notable examples include Arlen Specter (2009) and Jim Jeffords (2001), both driven by ideological distance from their caucus. However, Murkowski has remained within the Republican fold despite provocations, suggesting institutional loyalty or strategic calculation outweighs departure impulses. Her current positioning—respected by Democrats but not formally aligned—may serve her interests better than an official switch.
Key catalysts include the 2026 midterm cycle dynamics, Trump's continued influence over the Republican Party direction, and any major legislative confrontations. Murkowski's voting record and public statements through 2025 will signal whether ideological distance is widening. The market's current pricing suggests traders view departure as possible but unlikely given her demonstrated capacity to operate as a Republican dissident without formally leaving.
