Data: The four largest bitcoin mining pools control over 70% of the hash rate

According to ChainCatcher, as of June 23, 2026, Foundry Digital, AntPool, ViaBTC, and F2Pool collectively control over 70% of the Bitcoin network's hashrate, with approximately 31%, 18%, 13%, and 10% respectively. Foundry Digital is a US mining pool backed by Digital Currency Group and primarily serves large institutions and publicly listed mining companies.

D-Central reported a Nakamoto coefficient of 3 in the first half of 2026, meaning only three mining pools are needed to surpass half of the block output. ViaBTC faced stricter regulatory scrutiny in 2026, leading some miners to migrate to alternative pools such as EMCD.
