As of June 23, 2026, four Bitcoin mining pools — Foundry Digital, AntPool, ViaBTC, and F2Pool — collectively controlled more than 70% of the network's hashrate, according to a snapshot from miningpoolstats.stream. The concentration marks a two-tier market that increasingly favors institutional clients, leaving independent miners quietly reconsidering where to point their machines.
The 70% threshold
The data snapshot shows the four pools holding a combined share above 70%. That's a lot of control. The source, miningpoolstats.stream, tracks real-time hashrate distribution. No other pool came close to the top four's combined dominance. The numbers are from late June, so they're about a month old — but the trend has been building for a while.
A two-tier market
The facts describe the market as two-tier, and it's easy to see why. Large pools like Foundry and AntPool offer institutional clients stability, lower fees, and predictable payouts. Smaller miners, by contrast, face higher variance and less favorable terms. The gap isn't just about hashrate — it's about access. Institutional players get the best deals; independents get the leftovers.
What miners are doing
Independent miners are quietly reconsidering which pools to point their machines to. No mass exodus yet, but the calculus is shifting. If the big four keep tightening their grip, smaller pools could see a slow bleed of hashrate — or a sudden one if a major miner decides to switch. The decision isn't just about fees; it's about network health and who calls the shots.
It's unclear whether the concentration will increase further or if miners will migrate to smaller pools. The snapshot from June 23 is the latest available. Observers will be watching miningpoolstats.stream for the next update to see if the balance shifts — or if the top four tighten their hold even more.
