Bitcoin Hashrate Nears 1,001 EH/s as Difficulty Falls 19% [2026]

Bitcoin’s mining network is closing in on a milestone that would have sounded like science fiction a decade ago: one zettahash per second. As of September 4, 2026, network hash rate data trackers put total computing power at roughly 1,001 exahashes per second (EH/s), a level that barely existed in projections even two years ago. The climb hasn’t been a straight line. It followed a sharp drop in mining difficulty since the all-time high set in October 2025, a wave of hashprice recovery through the summer, and growing evidence that electricity, not hardware, now decides who survives in the mining business.

For an industry that spent 2024 and 2025 absorbing the fourth halving’s hit to block rewards, the numbers out this quarter tell a more complicated story than “number go up.” Hash rate is climbing while difficulty sits nearly a fifth below its peak. Mining pools are more concentrated than most retail investors realize. And a growing chorus of executives is warning that AI data centers are pulling capital and power away from proof-of-work mining altogether. This is a look at what the hard numbers actually show, why they matter for anyone holding, mining, or building on Bitcoin, and where the mining economy is likely headed next.
