CoworkingCafe (which you may remember we introduced as Yardi's new booking platform in w29/22) shares who the largest US operators are according to their data/listings based on number of locations.

The top 15 are: Regus (832), WeWork (246), Industrious (135), Spaces (117), Premier Workspaces (87), Office Evolution (81), Workstyle Flexible Workplaces (60), Intelligent Office (45), Expansive (43), Venture X (42), LocalWorks (31), COhatch (30), Carr Workplaces (27) and Serendipity Labs (27). They also share that they'd say there's 5,723 locations nationally.

I'm not sure about these results given I've not seen the data, but the national number seems very low, and Regus + Spaces are the same operator, but different brands, but interesting nevertheless.
