The four major Bitcoin mining pools control over 70% of the hashrate

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

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