This market will resolve according to the person who is appointed as the next permanent manager of the Philadelphia Phillies. If no permanent manager is appointed by January 31, 2027, 11:59 PM ET, the market will resolve to "Other." Appointments of 'interim,' 'caretaker,' or other non-permanent managers will not impact this market's resolution. An announcement of a new permanent manager's appointment before this market's close date will immediately resolve this market to the corresponding option, regardless of when the announced appointment goes into effect. The primary resolution source for this market will be official information from the Philadelphia Phillies; however, a consensus of credible reporting may also be used.**The Philadelphia Phillies' managerial situation stems from Rob Thomson's mid-April 2026 dismissal after a 9-19 start, which prompted president of baseball operations Dave Dombrowski to offer the role to Alex Cora (freshly fired by the Red Sox).** Cora declined to prioritize family time, leading to bench coach Don Mattingly's interim appointment. Mattingly engineered a sharp turnaround, guiding the club to a 66-58 record and NL East/wild-card contention by late August. Mid-August reporting from Bob Nightengale established the prevailing trader consensus: Mattingly must deliver a deep playoff run—ideally a World Series appearance or title—to earn the permanent job, positioning Cora as the frontrunner otherwise due to his proven track record and prior ties to Dombrowski. Internal or external names such as Ryan Flaherty, Will Venable, and others reflect broader speculation around coaching staff or available candidates, but the market reflects the high bar for Mattingly's retention amid the team's strong recent form and the front office's preference for an experienced external hire like Cora barring exceptional on-field results.
