For the first time in six years, Bitcoin's hashrate – the total computational power securing the network – has declined during the first quarter of 2026. According to data from Glassnode, the hashrate is currently down approximately 4% year-to-date, hovering around 1 zettahash per second (ZH/s). This marks a significant reversal from the consistent growth pattern observed over the past half-decade.
Historically, the hashrate has surged from roughly 100 exahashes per second (EH/s) five years ago, representing a tenfold increase. Each year, the metric rose during the first quarter and concluded with full-year growth exceeding 10%. In 2022, the figure nearly doubled. The 2026 downturn signals a fundamental shift in the economics of the Bitcoin mining sector.
The primary driver is the challenging financial environment for miners. With production costs estimated near $90,000 per Bitcoin and the spot price closer to $67,000, mining margins have turned negative. In response, a growing number of publicly listed miners are pivoting their infrastructure towards artificial intelligence (AI) and high-performance computing (HPC), where returns are perceived as higher and more predictable.
This strategic transition is being funded through debt issuance and sales of Bitcoin reserves, which in turn reduces capital reinvestment into mining hardware. Consequently, hashrate growth is becoming more sensitive to Bitcoin's price. Weaker prices are likely to trigger further declines as smaller, less efficient operators are forced to exit the market.
While a falling hashrate can raise concerns about network security, analysts suggest that decentralization may be a more critical factor than absolute size. Publicly listed U.S. miners have accounted for over 40% of the global hash rate. A reduction in their dominance could potentially lead to a more geographically distributed and decentralized network.
Despite the current slowdown, research firm CoinShares still forecasts the hashrate to grow to around 1.8 ZH/s by the end of 2026, conditional on Bitcoin's price recovering toward the $100,000 level.
