The greater Seattle–Tacoma–Bellevue metropolitan area attracted about $1.5 billion in venture-capital investment in the second quarter of 2026, according to the latest PitchBook–National Venture Capital Association (NVCA) monitor. The quarter was dominated by one large transaction: Everett-based fusion company Helion announced a $465 million Series G round in June, a deal that represented almost a third of the region’s total VC inflows for the quarter.
Concentration at the top and what it means locally
Helion’s financing, which valued the company at more than $15 billion, underlines the region’s continuing strength in deep-technology sectors such as energy innovation and aerospace-adjacent industries. The second-largest regional deal was Redmond-based Starcloud, which raised $170 million and surpassed a $1 billion valuation for its work on space-based data centers. Seattle companies Xbow and Gradial also made the top five rounds, raising $155 million and $65 million, respectively.
Other notable regional financings included Tukwila’s Starfish Space at an estimated $115 million, Seattle’s Endurance Energy ($54 million Series A for subsea geothermal development) and Seattle-based Vedana Therapeutics ($46 million Series A for migraine-prevention biotech).
- Top regional deals, 2Q 2026: Helion $465M; Starcloud $170M; Xbow $155M; Starfish Space $115M; Gradial $65M.
- Total deals: About 78 deals in the quarter, up slightly from 77 in the first quarter.
- Quarterly comparison: The $1.5B figure is below the roughly $2.3B raised in 2Q 2025, signaling a pullback from last year’s levels.
Numbers in context
| Metric | 2Q 2026 | 2Q 2025 |
|---|---|---|
| Total VC invested (greater Seattle) | $1.5 billion | ~$2.3 billion |
| Number of deals (greater Seattle) | ~78 | ~100 |
| Largest deal | Helion, $465M | — |
The national venture landscape grew in the same quarter: PitchBook and the NVCA reported about $143.9 billion deployed across an estimated 5,039 deals nationwide, up from $85.8 billion in the second quarter of 2025. But locally, the Seattle region’s decline from 2Q 2025 to 2Q 2026 highlights the unevenness of the recovery — a few very large rounds buoy totals even as overall deal counts and aggregate dollars dip.
“Helion’s Series G comprised almost a third of the $1.5 billion invested in greater Seattle area companies last quarter,” the PitchBook–NVCA account of the quarter noted.
For Seattle residents, these trends matter in practical ways. Large follow-on rounds like Helion’s can drive supplier demand, expand local manufacturing and create high-skilled job opportunities in engineering and operations. They also concentrate capital in specific sectors — fusion, space systems, AI and advanced biotech — which can deepen regional expertise but could leave other sectors quieter in the short term.
City and county economic-development officials, workforce groups and local investors will be watching whether follow-on hiring and supply-chain investment materialize in King and Snohomish counties. The coming months will also clarify whether the region can convert headline-grabbing valuations into broader, sustained job growth across the Puget Sound innovation ecosystem.
As PitchBook and the NVCA continue to publish quarterly monitors, the data will help Seattle stakeholders track how capital allocation shifts affect neighborhoods, employers and civic planning in the months ahead.
