The Tour Championship is part of the PGA Tour’s FedExCup playoffs.

The Tour Championship is explicitly identified as the final or culminating event of the PGA Tour’s FedExCup Playoffs. The tournament’s official website says the 2026 event is the playoffs’ final event, while the PGA Tour describes its field as the top 30 players in the FedExCup standings.tourchampionship.comtourchampionship.comField finalized for 2026 TOUR Championship, FedExCup Playoffs set for dramatic...pgatour.compgatour.comThe First Look: TOUR Championship+2 more

Independent coverage is consistent with those official descriptions. Golfweek identifies the Tour Championship as the finale of the 2026 FedExCup Playoffs, and Golf News Net describes the 30-player field as the final leg of the playoffs. The format has changed over time, including the use of a season-ending tournament to determine the FedExCup champion, but those format details do not alter the tournament’s status as part of the playoffs.golfweek.usatoday.comgolfweek.usatoday.comWhat to know about FedEx Cup Playoffs finale at 2026 Tour Championshipgolfdigest.comgolfdigest.comHow the FedEx Cup Playoffs work: The format, the stakes and the $100 million...+2 more

The AP also reports that the PGA Tour season concludes with the Tour Championship, and the tournament’s official announcement says the winner claims the FedExCup.
