BOO Seattle 2026: Set Times and Which Night Is Which

Insomniac emailed the day splits on September 1, and the 48 names on the BOO Seattle bill finally have a night attached. It’s 24 on Friday, October 30, and 24 on Saturday, October 31. WAMU Theater, 18+, as it has been since May.

No set times are out yet. Both nights run 5 PM to 1:30 AM on the official hours page, and nothing on the ticket page is marked sold out as of September 29.

GRiZ has the Friday. Subtronics has the Saturday. Those two were the whole flyer on May 27, and they land on opposite nights, which is the split you’d draw if you were trying to sell both.

Nothing else moved. We put the emailed graphic next to the official lineup page as it stood after Phase 3 in July, and the rosters match: 48 names then, 48 now, nobody added and nobody quietly gone. On a bill that’s been phasing since spring, that isn’t the default outcome.

The night is the only new information in the email. Both lists are above, and that’s all of it.

How the bill got here

BOO came in waves. On May 27 the flyer had two names. On July 6 the Phase 2 flyer filled in the wall: 38 names, with three slots smudged out. Phase 3 landed at the end of July and the smudges were gone.

The flyer prints alphabetically, so a blur has an address. Those addresses have names in them now. Cloonee sits where the gap between Clara Cuvé and Dansyn was. OMNOM sits between Morgan Seatree and PEDROZ. The third gap, between Elderbrook and Gramatik, came back holding two names instead of one, FRAZE and Getter, so which of them was under the blur is not something the alphabet can settle.

Phase 3 announced seven: Cloonee, Getter, OMNOM, Beebo, Usaybflow, FRAZE and Taylor Hadden. Two more names reached the official lineup page that no phase announcement covered at all: AMP and Leah York. A third, Jem.G, sat in Insomniac’s press copy back in July without ever reaching the flyer or the lineup page, and then turned up on both.

What still isn’t announced

No set times. No stages either. The day split says which night, and it doesn’t say which room, though Insomniac’s copy this year describes three.

One thing to know if you go looking yourself. The set times page on the official site is live and fully populated, and what’s on it is last year’s schedule: Zedd, RL Grime and NERO across the Grand Hall, the Bassment and the Corridor, dated October 31 and November 1, which were the 2025 dates. None of it applies to this year’s bill.

The real grid goes on this page the hour it lands, with wallpapers to match.
