Bitcoin is about to give miners a 16% lifeline, but $19 billion in AI deals is luring them away anyway

Bitcoin could lower mining difficulty by roughly 16% when its next adjustment arrives around July 26, handing the machines that remain online a considerably larger expected share of the network’s rewards while doing almost nothing to resolve the expensive power contracts, debt obligations and strategic pressures pushing some of the industry’s largest companies away from mining.

The network already lowered difficulty by 5% at block 957,600 on July 11, bringing it to 127.17 trillion. Hashrate Index reported that hashprice, the daily revenue miners expect from one petahash per second of computing power, stood at $30.88 per PH/s/day on July 13, with a seven-day average of $30.39.

That level was at or below breakeven for many operators depending on their power costs and machine models. While hashprice had recovered from the $27.60 level recorded around the beginning of July, it remains 37% below its October 2025 peak near $49.40.

Bitcoin’s protocol can automatically lower the computational burden required to produce blocks, but it can't renegotiate a miner’s electricity contract, refinance convertible notes, restore the value of aging machines, or make volatile mining revenue more attractive than a multibillion-dollar AI lease.
