Direct answer: As of late 2024–early 2025, a growing number of Starbucks locations across the United States have unionized, but the vast majority of Starbucks stores remain non-union. The unionizing effort has been led by Starbucks Workers United (SBWU) and spread from the first unionized Buffalo, New York store in December 2021 to hundreds of locations. Estimates frequently cited by union trackers indicate that hundreds of stores have held successful union elections and won recognition, while dozens of stores have faced election losses or ongoing organizing activities. Ongoing activity includes strikes and bargaining campaigns as SBWU and Starbucks negotiate a national contract. For the latest, store-by-store status and current unionization counts, refer to SBWU updates and union election trackers. Context and details you might find useful:

• First unionized store: Elmwood Avenue, Buffalo, NY, December 2021. This marked the initial success in the U.S. for Starbucks Workers United and sparked a broader organizing wave.

• Growth in filings and elections: By 2024–2025, filings to unionize moved into the hundreds of stores across many states, with a substantial number of successful elections. Ongoing campaigns continue in numerous locations.

• National trajectory: The organizing drive expanded from individual stores to a nationwide campaign, with ongoing bargaining and periodic strikes linked to contract negotiations and responses to corporate actions.

• Map and trackers: Several sources publish maps or updated tallies of unionized stores and ongoing campaigns, including store-by-store lists and state-level tallies.

If you’d like, I can pull the most current, store-level status from up-to-date trackers and present a concise list of unionized locations by state, plus any major recent developments (e.g., contract negotiations, strikes).
