Economy

Seattle's economy is driven by a mix of older industrial companies and new-economy internet and technology companies, as well as service, design, and clean technology companies. The city's gross metropolitan product (GMP) was $231 billion in 2010, making it the 11th-largest metropolitan economy in the United States. The Port of Seattle, which also operates Seattle–Tacoma International Airport, is a major gateway for trade with Asia and cruises to Alaska. It also is the 8th-largest port in the United States when measured by container capacity. Its maritime cargo operations merged with the Port of Tacoma in 2015 to form the Northwest Seaport Alliance.

Although it was impacted by the Great Recession, Seattle has retained a comparatively strong economy, and is noted for start-up businesses, especially in green building and clean technologies. In February 2010, the city government committed Seattle to become North America's first "climate neutral" city, with a goal of reaching net-zero per-capita greenhouse gas emissions by 2030.

Large companies continue to dominate the business landscape. Seven companies on Fortune 500 's 2022 list of the United States' largest companies (based on total revenue) are headquartered in Seattle: Internet retailer Amazon (#2), coffee chain Starbucks (#120), freight forwarder Expeditors International of Washington (#225), department store Nordstrom (#245), forest products company Weyerhaeuser (#354), online travel company Expedia Group (#404), and real-estate tech company Zillow (#424). Other Fortune 500 companies commonly associated with Seattle are based in nearby Puget Sound cities. Warehouse club chain Costco (#11), the largest retail company in Washington, is based in Issaquah. Microsoft (#14) is located in Redmond. Furthermore, Bellevue is home to truck manufacturer Paccar (#151). Other major companies headquartered in the area include Nintendo of America in Redmond, T-Mobile US in Bellevue, and Providence Health & Services (the state's largest health care system and fifth-largest employer) in Renton. The city has a reputation for heavy coffee consumption; coffee companies founded or based in Seattle include Starbucks, Seattle's Best Coffee, and Tully's. There are also many successful independent artisanal espresso roasters and cafés.

Before moving its headquarters to Chicago and then ultimately Arlington County, Virginia, aerospace manufacturer Boeing (#60) was the largest company based in Seattle. Its largest division, Boeing Commercial Airplanes, is still headquartered within the Puget Sound region. The company also has large aircraft manufacturing plants in Everett and Renton; it remains the largest private employer in the Seattle metropolitan area. In 2006 former Seattle Mayor Greg Nickels announced a desire to spark a new economic boom driven by the biotechnology industry. Major redevelopment of the South Lake Union neighborhood is underway in an effort to attract new and established biotech companies to the city, joining biotech companies Corixa (acquired by GlaxoSmithKline), Immunex (now part of Amgen), Trubion, and ZymoGenetics. Vulcan Inc., the holding company of billionaire Paul Allen, is behind most of the development projects in the region. While some see the new development as an economic boon, others have criticized Nickels and the Seattle City Council for pandering to Allen's interests at taxpayers' expense. In 2005, Forbes ranked Seattle as the most expensive American city for buying a house based on the local income levels. Owing largely to the rapidly increasing cost of living, Seattle and Washington State have some of the highest minimum wages in the country, at $15 per hour for smaller businesses and $16 for the city's largest employers.

Operating a hub at Seattle–Tacoma International Airport, Alaska Airlines maintains its headquarters in the city of SeaTac, next to the airport. Seattle is a hub for global health with the headquarters of the Bill & Melinda Gates Foundation, PATH (global health organization), Infectious Disease Research Institute, Fred Hutchinson Cancer Center, and the Institute for Health Metrics and Evaluation. In 2015, the Washington Global Health Alliance counted 168 global health organizations in Washington state. Many are headquartered in Seattle.
