Bitcoin's Top Four Mining Pools Control Over 70% of Hashrate

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

In the first half of 2026, D-Central reported a Nakamoto coefficient of 3, meaning just three mining pools could collectively produce more than half of the blocks. ViaBTC faced stricter regulatory scrutiny in 2026, prompting some miners to shift to alternative pools like EMCD.
