In a coast to coast real estate matchup conveniently timed with Super Bowl LX chatter, CoStar is handing Boston the win over Seattle. The firm’s market face-off compares the two metros across office, industrial, retail and multifamily, and Boston edges ahead. Both cities are wrestling with pockets of oversupply, but Boston’s stronger office rebound and stubbornly tight retail fundamentals pull it in front, while Seattle is still taking hits from big tech lease rolloffs. In Boston, life science pressure is a problem, yet it has not fully erased firmer leasing in other parts of the market.
CoStar’s scorecard and the stats
As reported by CoStar, the Boston metro clocks in at about 5.03 million people, with roughly 2.8 million jobs and a median household income above $118,000. Seattle’s metro, by comparison, is shown near 4.2 million residents. CoStar’s analysts stacked the markets on size, recent absorption, completions and rent trends across industrial, retail, multifamily and office, then concluded Boston holds the stronger overall commercial real estate profile heading into 2026. The report pins Boston’s advantage on office conditions that are expected to stabilize late in 2025, along with retail fundamentals in the region that remain persistently tight.
Seattle’s big tech hangover
Seattle’s soft spot is office, where expiring big leases and tech consolidation hit hardest. Coverage in The Seattle Times notes Microsoft opted not to renew roughly 750,000 square feet at The Bravern in Bellevue and also walked away from several other large Eastside leases, moves that left significant blocks of space back on the market. At the same time, city permitting records confirm Microsoft is pressing ahead with a multi year Redmond campus refresh that adds roughly 3 million square feet as it consolidates and modernizes its headquarters, a shift that is reshaping local office demand and supply dynamics (City of Redmond).
Boston’s late season rebound
Boston, by contrast, managed a late 2025 office turnaround that lifted its score. Local reporting and market briefs summarized by Boston.com show that stronger leasing activity and several large renewals produced positive net absorption in the second half of 2025. Retail vacancy across much of the metro stayed unusually tight, another factor CoStar cites in giving Boston the edge. Analysts, however, are clear that life science submarkets remain a weak link, and elevated new deliveries mean parts of the Boston story are still fragile.
What investors and tenants should watch
Life sciences oversupply continues to drag on Boston’s fundamentals even as other sectors firm up, a problem that industry coverage says could take years to work through (Bisnow). At the same time, national brokerage reports and trade coverage indicate the U.S. office market moved toward cautious stabilization in late 2025, with demand improving for high quality buildings and a widening split between best in class product and older, legacy stock (industry reports). That divide matters, since landlords with modern, amenitized assets are seeing more traction, while owners of dated space face growing pressure to convert, upgrade or discount heavily.
The topline from CoStar’s matchup is straightforward: Boston currently looks more resilient across several commercial sectors, yet both metros still hold a mix of opportunity and risk. For tenants and investors on the ground, the real game plan is local and tactical, watching big tenant decisions, new project completions and the life science pipeline, because those moving pieces will determine whether Boston’s advantage over Seattle lasts into 2026.
