Bitcoin's mining difficulty is set to drop by 15.3% on Jul 26, 2026 06:20 UTC, shifting from the current 127.17T to an estimated 107.71T. The adjustment takes effect at block 959,616 - the end of the current 2,016-block epoch - when 255 blocks remain.
At 127.17T and an estimated 997 EH/s of network hashpower, the daily mining revenue across the entire network is approximately $29,424,150 at $65,387 per BTC. The current cycle is 87.35% through, having completed 1,761 blocks since the last retarget at block 957,600.
What This Means for Miner Revenue
A 15.3% difficulty drop means every miner with the same hashrate earns a bigger share of the 3.125 BTC block reward. A 1,000 TH/s operation at $65,387/BTC would see daily revenue increase from approximately $29.51 to $34.84, roughly a 18% boost for the same hardware.
This is one of the largest difficulty drops in recent history. Miners running hardware that was barely profitable at 127.17T could return to positive margins at 107.71T. Use CoinWarz's mining calculator to model the impact on your specific setup.
Why Blocks Are Running Slower Than Target
Blocks have been arriving an average of 1 min 48 sec slower than the 10-minute target - a signal that total network hashpower has fallen relative to the previous epoch. This typically happens when older ASICs go offline permanently, miners exit due to low profitability, or seasonal demand shifts. The 15.3% difficulty drop is Bitcoin's automatic response to bring block times back to the 10-minute target.
