Woofun AI data shows that Foundry Digital, AntPool, ViaBTC, and F2Pool collectively command more than 70% of the Bitcoin network's hash rate as of June 23, 2026. Their individual shares stand at approximately 31%, 18%, 13%, and 10%, respectively. Foundry Digital, backed by Digital Currency Group, primarily serves large institutions and publicly listed mining companies.

D-Central reports a Nakamoto coefficient of 3 for the first half of 2026, indicating that only three pools are required to control majority block production. Amid stricter regulatory scrutiny on ViaBTC in 2026, some miners have migrated to alternative pools such as EMCD.
