Most arenas lock their plazas behind event-day turnstiles, but Chase Center's 11-acre Thrive City operates as a public square with its own calendar of free basketball tournaments, live music, fitness classes, and sports watch parties. The outdoor space in Mission Bay hosts year-round programming—some tied to Warriors games, much of it independent—and the September 5 Hoop It Up 3x3 Basketball Tournament marks one of the biggest draws on the fall schedule. Kevin Garnett's touring event brings age-bracketed competition to the plaza courts, with recreational and Pro-Am divisions running from 9 a.m. into late afternoon. Between tournament weekends, Thrive City streams football Sundays on San Francisco's largest outdoor video board, books local musicians for Tuesday lunch concerts, and partners with Kaiser Permanente for drop-in yoga and HIIT sessions. It's the rare arena district that functions as a neighborhood gathering spot whether or not the building itself has a ticketed event.
Karpo tracks Thrive City's rotating schedule of tournaments, watch parties, and drop-in fitness classes so you never miss registration deadlines or free event RSVPs.
The 11-acre plaza that runs year-round
Thrive City surrounds Chase Center with an 11-acre open plaza that operates independently of arena events, hosting more than 500 free community programs since July 2023. The space sits in Mission Bay between Third Street and the bayfront, anchored by Kaiser Permanente's partnership focus on health and wellness. You'll find rotating restaurant patios, a central lawn, and San Francisco's largest outdoor video board broadcasting everything from March basketball to September tennis finals.
Programming runs Tuesday through Sunday most weeks, with heavy concentration on weekend mornings for family fitness classes and Saturday tournament blocks. The video board handles split-screen feeds during multi-game college basketball days, and the plaza stays open for walk-up viewing even when Chase Center hosts ticketed Warriors or concert crowds inside. Harmonic Brewing and other Thrive City tenants keep outdoor seating available during watch parties, though you're welcome to bring lawn chairs for non-tournament days—just no coolers or outside alcohol.
Hoop It Up brings Kevin Garnett's 3x3 format west
The next Hoop It Up 3x3 Basketball Tournament lands at Thrive City on Saturday, September 5, 2026, with tip-off at 9 a.m. and divisions running through late afternoon. Kevin Garnett's tour, launched in 1989 and revived under his ownership, books Chase Center's outdoor courts twice per season—fall and spring rounds—with age brackets from 10-and-under through 18-plus adult recreational and Pro-Am tiers. Each roster holds five players maximum: three on court, two substitutes. First team to 21 points wins, and every squad is guaranteed four games regardless of bracket results.
Registration costs $250 per team and closes Wednesday, September 2, at 11:59 p.m. through hoopitup.com/sanfrancisco. The Men's Pro-Am division winner earns a travel voucher to the Hoop It Up National Championship, while recreational brackets award medals and on-site gear. Spectators register for free tickets through the same portal—capacity is first-come, so RSVP early if you want guaranteed lawn access during peak mid-morning games when the September sun hits the plaza hardest.
Courts occupy the western end of Thrive City near the Third Street Muni stop, with bleacher seating and standing-room perimeters. The video board streams live bracket updates and replays between games, and food trucks typically supplement the plaza's permanent restaurant lineup on tournament Saturdays. Parking at the Chase Center Garage (99 Warriors Way) opens at 7 a.m., but spaces disappear by 8:30 a.m.—T-Third or N-Judah to King Street, then a five-minute walk, is the smarter play.
Gaming launches and 2K watch parties on the big screen
Thrive City has hosted 2K gaming events and live-streamed launch coverage in past fall programming blocks, typically timed to September release windows when the plaza can handle evening crowds without conflicting with Warriors preseason. While the official 2K27 release date hasn't been announced as of August 2026, expect Thrive City to mirror its 2025 format: outdoor watch parties for reveal streams, demo kiosks on the plaza, and potential tie-ins with Harmonic Brewing or other tenants offering game-day specials. The video board's split-screen capability means simultaneous tournament bracket feeds and live gameplay demos during multi-event Saturdays.
Past gaming activations have included pop-up stations with controllers, leaderboard competitions, and giveaways coordinated with local retailers. If 2K27 follows the franchise's usual early-September timing, registration for related Thrive City events will likely open in mid-August through the standard thrivecity.com RSVP system. Check the Chase Center events calendar for confirmed dates—programming announcements typically land six weeks out, and popular gaming slots fill within 48 hours of going live.
Weekly fitness and live music between big events
Kaiser Permanente sponsors free weekly fitness classes every Wednesday from noon to 1 p.m. and Saturdays from 10 a.m. to noon, rotating through yoga, pilates, HIIT, and stretch sessions. Instructors set up on the central lawn with portable sound systems, and participants bring their own mats—though a limited number of loaners appear on a first-come basis. The Saturday morning slot runs year-round and overlaps with Little Bears Music Classes for toddlers on select Friday mornings at 10 a.m., so families can double up on programming if schedules align.
The Live Music Lunch Series books local Bay Area acts like Swami 3, Matt Bolton, and Tracy Cruz Trio on rotating Tuesdays from noon to 1:30 p.m., currently scheduled through early November. Performances happen near the restaurant patios, and you're encouraged to grab takeout from Starbird, Harmonic, or other Thrive City tenants. Seating is informal—plaza benches, low walls, or standing crowds depending on the act's draw. No RSVP required for music or fitness; just show up.
Football Sundays and tennis watch parties
Select Sundays through September and October feature free football viewings on the outdoor board, with lawn games (cornhole, ladder toss) scattered across the plaza and food service from Thrive City vendors. Specific game schedules aren't locked until the week prior, but expect 10 a.m. starts for East Coast kickoffs and doubleheader splits when Bay Area teams play simultaneously. The US Open Watch Party on Sunday, September 7, from 10 a.m. to 3 p.m. adds red-ball tennis courts to the plaza in collaboration with USTA Northern California, and Harmonic Brewing extends its patio hours for the occasion.
These watch parties don't require tickets, but arriving by 9:45 a.m. secures better lawn positioning before crowds thicken. The video board's audio carries across the plaza, so even restaurant patios a hundred feet away catch commentary. Prohibited items include outside alcohol, coolers, tents, bicycles on the plaza (lock them at Third Street racks), and amplified personal sound—the last rule matters if you're planning a tailgate-style setup.
Practical notes
Thrive City sits at Third Street and 16 Street in Mission Bay, accessible via Muni T-Third (Third Street stop) or N-Judah to King Street with a short walk east. The Chase Center Garage at 99 Warriors Way charges daily rates and opens seven days a week, but tournament Saturdays and watch-party Sundays fill early—public transit is the recommended route. Free spectator RSVPs for tournaments and select events go live at thrivecity.com; fitness classes and Live Music Lunch Series are drop-in with no registration. The plaza enforces a no-outside-alcohol policy, but Harmonic Brewing, Starbird, and other tenants serve beer and cocktails on-site. Programming runs year-round with heaviest concentration June through November. If you drink at Thrive City events, plan your ride home with Muni, rideshare, or a designated driver—enjoy responsibly.
