Bitcoin ($BTC) transaction fees now account for just 0.69% of miner revenue as major players pivot to AI.
Key points:
- Bitcoin miners now rely on block subsidies more than at any time in the past decade, data shows.
- Bitcoin hash rate has declined by 33% since October 2025.
- Analysts warn that miners switching to AI could affect the network.
Bitcoin miner fee revenue share returns to 2016 levels
Data from onchain analytics platform Glassnode shows that fees as a proportion of miner revenue remain near decade lows after falling to just 0.52% in April.
Miners face ongoing pressure as declining Bitcoin prices and rising electricity costs squeeze profits and force smaller players out of the market. Glassnode co-founder Rafael Schultze-Kraft noted that fees had made up less than 1% of miner revenue for almost a year.
“Bitcoin was below $400 the last time fee share was this low,” he said on X.

When transaction fee revenue drops, miners increasingly depend on the fixed block subsidy for income — the amount of newly minted $BTC awarded for each mined block, currently 3.125 $BTC. Bitcoin’s value has fallen nearly 50% since its October 2025 all-time high, dragging down the US dollar value of the block subsidy and further squeezing miners’ profit margins.
The latest data from onchain analytics resource Checkonchain puts the estimated average cost of producing one Bitcoin at $78,254 as of Tuesday — almost 23% above the current spot price.

Bitcoin’s network hash rate, an estimated measure of the computing power securing the network, reflects a mining sector in flux. Hash rate has declined from its October 2025 peak of 1.3 zettahashes per second (ZH/s) to 861 exahashes per second (EH/s), Checkonchain shows — a drop of 33%.

Analyst: AI pivot is “concerning development”
In analysis published at the weekend, independent analyst William Clemente acknowledged the downturn, while noting that miners would have been incentivized to boost activity through automated difficulty readjustments. With difficulty itself now rising again, miners’ shift toward more lucrative AI computing has become conspicuous.
“There is no other way to slice it, hash rate has been in a decline. This has taken place as miner margins got squeezed post 2022 from more competition are higher energy prices, but more importantly the pivot of many into AI/HPC, which so far have shown to be prudent business decisions for the public names that have done it,” he wrote.
As Cointelegraph reported, Bitcoin miner CleanSpark recently refocused on AI, switching to operating data centers after missing profit targets. Another miner, Keel Infrastructure, shut down all its US mining operations after revenue fell 50% in the second quarter.
“This dynamic has been reinforced as Bitcoin has underperformed AI related assets & the rate of change in demand for compute,” Clemente added.
Charles Edwards, founder of hedge fund and AI platform Capriole Investments, directly linked the drop in hash rate to public miners’ AI pivot.
“This is the least talked about, concerning Bitcoin development in 2026,” he argued on X, noting that the trend had accelerated since April.
