About this venue
The 2026 meeting is held in the Arch building of the Seattle Convention Center. Arch at 705 Pike Street, the Seattle Convention Center's original building, features 61 meeting rooms, four ballrooms and six exhibit halls, as well as a number of cozy seating areas. All meeting rooms and ballrooms are fully carpeted and equipped with advanced connectivity and audiovisual support, and the building sits adjacent to Freeway Park, Seattle's largest downtown public space.
Arch has 236,700 square feet of exhibition space on the fourth floor, divided into two halls connected by a 90-foot-wide skybridge across Pike Street, with capacity for 1,105 booths or 8,000 people seated for plenary sessions. The building's main public space is a four-story atrium with restaurants, shops, and public artwork. The wider campus, combined with the newer Summit building, covers roughly 1.5 million square feet.
