Bitcoin Mining Difficulty Drops 14% as AI Pivot Squeezes Revenue

Woofun AI reports that Bitcoin’s mining difficulty has retreated below its year-earlier level, a rare occurrence driven by weak mining economics and a strategic pivot toward artificial intelligence. This contraction marks only the second such year-over-year decline in the network’s history, with Luxor’s Hashrate Index highlighting the dual pressure of compressed revenues and capital diversion.

The metric currently stands at 126.23 trillion, reflecting a 0.74% drop and sitting 1.1% below the 127.62 trillion recorded a year earlier. This represents a 19.1% decline from the 155.97 trillion all-time high reached in November 2025. Difficulty adjusts every 2,016 blocks, or roughly every two weeks, to maintain Bitcoin’s average block time near 10 minutes. The current 14% drop from the January peak follows a 10% decline in June and a 5% fall in July. The only prior year-over-year decrease occurred after China’s 2021 mining ban, which removed half the network’s computing power before miners relocated.

Structurally, the current downturn is rooted in mining economics rather than regulatory bans. Luxor’s Hashrate Index attributes the capacity reduction to falling bitcoin prices, compressed mining revenue, and the diversion of operators toward AI and high-performance computing infrastructure.

Woofun AI data shows that curtailments in Texas and disruptions in other mining regions further exacerbated the decline. These factors collectively reduced the computing power competing during the previous adjustment period.

Hashprice, measuring expected miner revenue per unit of computing power, fell to $27.66 per petahash per day in late June, within one cent of its February low. Although it has since risen to $31.7, Luxor’s forward market prices an average hashprice of $31.85 per petahash per day through December. This modest premium over recent spot levels suggests miners expect little revenue recovery for the remainder of 2026.
