The 2026 Pokémon World Championships do not begin until Friday, Aug. 28, but San Francisco's transportation plans make clear that the event's footprint will last much longer than three days.
The championships and PokémonXP are scheduled for Aug. 28 through Aug. 30 at Moscone Center, according to Pokémon's official Worlds site. The final day extends south to Mission Bay, where championship finals are scheduled at Chase Center on Sunday, Aug. 30.
For people who are not attending, the practical story is the public space around the event. A San Francisco Board of Supervisors resolution authorizes the closure of the sidewalks on both sides of Howard Street between Third and Fourth streets from Aug. 25 through Aug. 31, subject to the city's normal street-closure approvals. The resolution says the closure is intended to accommodate PokémonXP and the World Championships.
SFMTA's major-event planning list shows an even wider anticipated traffic footprint: a Pokémon World Championship closure on Howard between Third and Fourth from Aug. 19 through Sept. 1, plus daily Fourth Street restrictions during event activity. Those are planning entries rather than a guarantee that every restriction will be in force at every hour, so drivers should check current SFMTA notices before a trip.
Saturday, not Sunday, is now the biggest Oracle Park collision
The baseball schedule matters because Oracle Park sits less than a mile from Moscone Center and uses many of the same transit corridors and approaches through SoMa.
Major League Baseball's current Giants schedule lists a 1:05 p.m. and 7:05 p.m. split doubleheader against Arizona on Saturday, Aug. 29. MLB separately announced that the game originally scheduled for Sunday was shifted into the Saturday doubleheader. That makes Saturday the day when convention traffic and two baseball crowds will overlap most directly.
Friday is not empty either: the Giants are scheduled to host Arizona at 7:15 p.m. while Pokémon Worlds and PokémonXP are underway at Moscone. Sunday loses the Giants game but adds the championships' Chase Center finale to the downtown activity.
The correction to the baseball schedule is easy to miss because older event calendars may still show a Sunday game. Anyone planning around Oracle Park next weekend should use the Giants' current schedule rather than an older calendar.
The event itself is not a simple walk-up festival
Pokémon's official event information describes the weekend as both a championship competition and a fan convention. Access has been managed through advance pass and interest-list systems, so people should not assume they can arrive at Moscone and buy admission at the door.
That does not mean the public impact is limited to ticket holders. Moscone load-in, security, fan traffic, rideshare activity and the Chase Center finale create a transportation footprint around the venues even for people simply trying to cross SoMa.
What San Franciscans should plan around
If you are driving through downtown, the safest assumption is that Howard Street between Third and Fourth will be constrained around the event and that adjacent streets may have intermittent restrictions. The city's planning documents also extend beyond the convention itself, which means teardown may continue to affect the block after Sunday's finals.
For transit riders, the overlap with Oracle Park is the bigger warning. Saturday's doubleheader will put repeated surges of riders onto Muni and the same downtown streets used by Pokémon attendees. SF News Today's live transit page can be used to check Muni and BART alerts and arrivals before leaving.
For drivers, an older mental map of the weekend could be particularly misleading: the Giants' Sunday game is no longer on Sunday, while Pokémon's Chase Center finale is. In other words, the event pressure shifts from Oracle Park on Saturday to Chase Center on Sunday rather than simply stacking both venues at once.
The broader lesson is that a three-day convention can produce a nearly two-week street-management window. For residents, workers and visitors, the useful dates begin before Aug. 28 and do not necessarily end when the champions are crowned.
