Resolution criteria on PolyGram: This market will resolve according to “Yes” if Mike Vrabel ceases to be the Head Coach of the New England Patriots for any period of time between market creation and the specified date (ET). Otherwise, this market will resolve to "No". Temporary absences (including but not limited: to medical leave, compassionate leave, suspension, or touchline bans) will not be considered. An announcement of Mike Vrabel's resignation/firing before this market's end date will immediately resolve this market to "Yes", regardless of when the announced resignation/firing goes into effect.

Market outcomes
| Mike Vrabel out as Patriots Head Coach by Dec 31, 2026? | 22% YES | 78% NO |
Mike Vrabel was appointed as New England Patriots head coach in May 2024 after a successful tenure with the Tennessee Titans, where he compiled a 54–45 record over eight seasons. The question centres on whether he will remain in the position through the end of 2026, or whether he will be dismissed or resign before that date. The current order book on Polymarket implies a 22% probability of his departure, reflecting market participants' assessment that Vrabel is likely to retain the role through the settlement window.
Historical precedent suggests NFL head coaches face elevated turnover risk during rebuilding phases. The Patriots have undergone significant roster changes since Vrabel's arrival, and comparable situations—such as Bill O'Brien's tenure in Houston or Jeff Fisher's extended run in St. Louis—show that coaches managing extended rebuilds face pressure if early results disappoint. Vrabel's defensive pedigree and prior success provide some insulation, but the Patriots' competitive timeline remains uncertain. The 22% probability reflects moderate confidence in his stability rather than exceptional job security.
Key catalysts include the 2025 and 2026 NFL seasons themselves; sustained losses or internal dysfunction could accelerate ownership's decision-making. Quarterback development will be particularly scrutinised given the franchise's post-Brady transition. Any public statements from Patriots ownership regarding coaching evaluations, or unexpected mid-season announcements, would move the probability sharply. The settlement mechanism—which resolves immediately upon announcement of resignation or firing, regardless of effective date—means traders should monitor official team communications closely.
