Tech Is Not Leaving Seattle. It Is Expanding Across the Lake.

The numbers on the Seattle side of the equation are stark. Downtown Seattle’s office vacancy rate reached a record 34.7% in the fourth quarter of 2025, a figure that reflects years of remote work, corporate belt-tightening, and a persistent public safety narrative that has made some companies reluctant to anchor their operations in the city center. Bellevue’s vacancy rate is higher in absolute terms but is trending sharply in the opposite direction and is expected to drop below 20% within a year. No new office buildings are planned for the Eastside in 2026, meaning the demand being absorbed is filling existing stock rather than waiting on new construction. That is a meaningful signal about the pace and seriousness of the shift.

What is driving companies to Bellevue is a combination of factors that have compounded over time. The completion of the Sound Transit Cross Lake Connection earlier this year linked Bellevue directly to Seattle’s light rail network for the first time, making the Eastside more accessible than it has ever been. Office rents in Bellevue remain competitive. The surrounding residential neighborhoods, school districts, and quality of life considerations carry weight for the engineers and executives companies are trying to recruit and retain.

None of this means Seattle is finished as a tech city. The infrastructure, talent pool, and institutional history that built Amazon, Microsoft, and a generation of startups do not disappear because vacancy rates rise or because a handful of companies choose Redmond over Belltown. But the geography of the region’s tech economy is being redrawn in real time, and Bellevue is no longer auditioning for a supporting role. It has already claimed the lead.

Seattle and Bellevue are forming what analysts are beginning to call a dual-core economy, with scale and established infrastructure on the Seattle side and expansion and momentum on the Eastside. For a region that has long defined its tech identity around a single city, that shift represents something genuinely new.
