Bitcoin miners earn $1.08B in May as BTC falls under $66k

Bitcoin miners generated $1.086 billion in revenue in May 2026, the first monthly haul above $1 billion since January. About $1.079 billion of the total came from the 3.125 BTC block subsidy; transaction fees contributed a small share of revenue for the month, though fee income rose to roughly 1.16% of block rewards over the most recent 24-hour period.

Industry data show the hashprice — the daily dollar value earned per petahash per second — fell 17.82% over the past 30 days, from about $37.44 to $30.77 per PH/s. That decline reduced the daily revenue earned by each unit of compute.

Network hashrate also decreased, moving from roughly 1,000 exahashes per second to below 975 EH/s. At 8 p.m. ET on June 2, average block intervals were recorded at 10 minutes and 49 seconds, longer than the network target of 10 minutes.

Bitcoin’s intraday low of about $65,362 on June 2 coincided with the weaker hashprice and lower hashrate. If block production continues at the current slower pace through roughly June 13, current estimates point to a potential 7.5% reduction in mining difficulty.

A lower difficulty would reduce the amount of computational work required to find blocks and would change the distribution of rewards per unit of hashpower. Miners begin June carrying the May revenue gain, while near-term earnings will depend on bitcoin’s price movement, short-term fee levels and whether mining difficulty adjusts as projected.
