This Group of Four Now Dominates Over 70% of a Key Blockchain Resource

Bitcoin mining is looking little similar a wide-open contention and much similar a choky club. A CryptoSlate spouse nonfiction published connected 07/08/2026, citing miningpoolstats.stream information arsenic of 06/23/2026, says Foundry Digital, AntPool, ViaBTC, and F2Pool unneurotic relationship for much than 70% of the network’s hashrate. The displacement is fueling what the sum calls a “two-tier market,” with the biggest pools progressively tuned for organization clients portion independents and mid-size operators get squeezed. Some smaller miners are already softly reconsidering wherever they constituent their machines, particularly arsenic ViaBTC faces added regulatory scrutiny successful 2026.

Bitcoin mining is often talked astir similar a wide-open frontier, but mid-2026 looks much similar a fistful of toll roads. A July 8, 2026 CryptoSlate article (partner content) points to a June 23, 2026 snapshot showing conscionable a fewer pools taking an outsized relation successful wherever blocks get made, and what benignant of miners get served best.

The emergence of 4 ascendant players successful Bitcoin mining

The estimated divided was stark: Foundry astatine 31%, AntPool astatine 18%, ViaBTC astatine 13%, and F2Pool astatine 10%, per 31%, 18%, 13%, 10% figures cited successful the coverage.

One item that matters for US operators is that Foundry is US-based and backed by Digital Currency Group. The excavation is described arsenic being built chiefly for large-scale, organization operators and publically traded mining companies, with strict KYC requirements baked into however it onboards clients.

A two-tier marketplace takes shape

CryptoSlate frames the attraction arsenic a “two-tier market,” wherever the biggest pools progressively optimize for organization miners. That benignant of optimization is usually invisible until you are the 1 warring for responsiveness, predictable payouts, oregon relationship support, and it is wherefore autarkic and mid-size miners are described arsenic softly rethinking wherever they constituent their machines.

The cardinal displacement is little astir immoderate azygous pool’s branding and much astir what standard buys you. When a pool’s concern is tuned for fleets and compliance-heavy customers, smaller miners tin extremity up feeling similar borderline cases alternatively of the halfway product.

Scrutiny, switching costs, and the hunt for alternatives

ViaBTC, which held 13% successful the mid-2026 stock estimates, has faced expanding regulatory scrutiny this twelvemonth that has peculiarly affected miners tied to Russia and different CIS countries. The reporting describes relationship restrictions, abrupt KYC demands, and impermanent money freezes, the benignant of friction that tin marque adjacent loyal miners reconsider their setup.

In the aforesaid coverage, EMCD is positioned arsenic an alternative: it claims implicit 30 EH/s of hashrate, with fees starting astatine 1.5% nether FPPS, compared with astir 4% charged by galore comparable pools. EMCD was founded successful 2017 and made its archetypal excavation disposable successful February 2018.

What centralization looks similar successful the metrics

In D-Central’s H1 2026 snapshot (data arsenic of June 19, 2026), Bitcoin mining pools had a Nakamoto coefficient of 3, meaning lone 3 pools were needed to transcend fractional of each blocks mined, with Foundry USA astatine astir 27% of blocks, per Nakamoto coefficient data.

And the leaderboard keeps moving. In the latest 7-day model posted connected July 16, 2026, Simple Mining’s rankings database Foundry USA astatine 27.0%, with F2Pool and AntPool some astatine 17.2%, ViaBTC astatine 9.5%, and SpiderPool astatine 5.5%.
