For the first time in six years, the bitcoin hashrate, the total computational power securing the network, fell during the first quarter. It is currently down around 4% year to date, hovering around 1 zettahash per second (ZH/s).
Over the past five years, the rate has surged from roughly 100 exahashes per second (EH/s), a 10-fold increase, according to Glassnode data. Each year, the metric rose during the first quarter and ended with strong full-year growth in excess of 10%. In 2022, the figure almost doubled.
The AI Pivot
The shift in 2026 reflects changing economics across the bitcoin mining sector. With production costs near $90,000 per bitcoin and the spot price closer to $67,000, margins are negative. In response, many publicly listed miners are switching to artificial intelligence and high-performance computing infrastructure, where returns are higher and more predictable.
This transition is being funded through debt issuance and bitcoin sales, reducing reinvestment into bitcoin mining. As a result, hashrate growth is becoming more sensitive to the cryptocurrency’s price, with weaker prices likely to trigger further declines as smaller operators exit.
While a falling hashrate may raise concerns about network security, decentralization may matter more than absolute size. Publicly listed U.S. miners have accounted for over 40% of the global hash rate, and a reduction in their influence could lead to a more geographically distributed network. In that sense, the current shift may ultimately support decentralization.
Despite the slowdown, CoinShares still forecasts hashrate growth to around 1.8 ZH/s by the end of 2026, conditional on bitcoin recovering toward $100,000.
