Data: The four major Bitcoin mining pools control over 70% of the hash rate

As of June 23, 2026, Foundry Digital, AntPool, ViaBTC, and F2Pool collectively control over 70% of the Bitcoin network's hash rate, accounting for approximately 31%, 18%, 13%, and 10%, respectively. Foundry Digital is a U.S. mining pool supported by Digital Currency Group, primarily targeting large institutions and publicly listed mining companies.

D-Central provided a Nakamoto coefficient of 3 for the first half of 2026, meaning that only 3 mining pools are needed to exceed the majority of block production.
