Bitcoin Hashrate Falls Under 1 ZH/s For First Time in Months

The Bitcoin network hashrate has fallen under 1,000 exahash per second (EH/s) for the first time since mid-September, with one analyst tipping the decline to continued interest in AI. 

The Bitcoin hashrate is currently on a seven-day moving average, after dropping below 1,000 EH/s, or 1 zetahash per second (ZH/s), on Saturday, according to Hashrate Index data.

It has now fallen nearly 15% since its seven-day moving average peak of 1,157 EH/s on Oct. 19.

In a Monday post on X, StandardHash CEO and founder Leon Lyu the fall to Bitcoin miners reallocating power to in pursuit of higher profitability margins.

Last year, TheMinerMag called 2025 the for Bitcoin miners due to collapsing revenue and surging debt as major obstacles. 

Many have turned to artificial intelligence and high-performance computing, as Bitcoin mining facilities feature large-scale power access and cooling infrastructure that can be repurposed beyond SHA-256 hashing.

Lyu also speculated that some manufacturers, including Bitmain, could be deploying surplus machines through opaque or indirect arrangements, which he said might mean publicly reported hashrate data underestimates actual capacity.

“The Bottom Line: While manufacturers are plugging in their own surplus stock, the net outflow of hashrate confirms the immense pressure on miner profitability. AI isn’t just a trend; it’s actively competing for the grid.”

The fall also comes despite the dropping four times since Nov. 12, 2025, from 156 trillion to 146.5 trillion, which makes Bitcoin mining easier by reducing the amount of computational work needed to find a block. 

The has also risen from $37.15 to $40 per petahash per second per day over the last month, signaling improving
