Keep in mind that there are different forms of co-ops. Most generally, worker-owned, customer-owned, and producer-owned.

Producer co-ops are often hiding in plain sight, and may not match preconceived views of crunchy-hippy businesses. For a long time, Visa International (the credit card company) was a producer co-op of member banks (it began trading publicly in 2008). Its major shareholders remain banks and investment companies.

Producer co-ops are also common in agriculture and food, as well as some media / creative fields. Associated Press, Blue Diamond (almonds/nuts), Cabot Creamery, Land O'Lakes, Welch's, and Sunkist are all co-ops, largely producer-owned AFAIR.
