Lumen Field

Lumen Field in downtown Seattle is shared by the NFL's Seahawks and MLS's Sounders, an open-air bowl engineered with a partial roof that traps and amplifies the roar of its "12s." The steep, tight seating angles put fans right on top of the field, giving both football Sundays and Sounders match days an unusually intense, enclosed feel for an outdoor stadium. Sounders crowds routinely rank among the largest in MLS, and the building's design has made noise itself part of the home-field advantage. The Pacific Northwest's soccer-mad fan culture makes it a natural stop on the 2026 World Cup map.

Opened in 2002 as Seahawks Stadium (later Qwest Field, then CenturyLink Field), the venue set Guinness World Records for crowd noise twice in 2013, peaking at 137.6 decibels during a Monday Night Football game against the Saints. Seahawks fan noise has literally registered as seismic activity, most famously the 2011 "Beast Quake" triggered by Marshawn Lynch's playoff touchdown run, with further tremors recorded during Sounders MLS Cup and CONCACAF Champions League celebrations. The Sounders have drawn some of the largest gates in North American soccer history here. It now joins the 2026 World Cup host list for the first time.
