Bitcoin's flat 24 hours hide a bigger mining shakeup

Bitcoin closed roughly flat over the past 24 hours near $63,400, a quiet session by recent standards, while the more consequential shift in the Bitcoin economy played out further from the price chart: public miners keep redirecting mining capacity toward AI hosting deals rather than new hashrate.

Price action stayed contained: Bitcoin failed a recovery attempt toward $63,900–$64,010 resistance and settled back near $63,400, still inside the $62,000–$66,000 range that has held since the July CPI release. US spot Bitcoin ETFs recorded a $61.1 million net outflow, led by Fidelity's FBTC at $46.8 million and BlackRock's IBIT at $14.3 million, reversing a brief single day of inflows, according to Farside Investors data. Ether ETFs moved the opposite direction, pulling in $7.4 million, entirely via BlackRock's ETHA.

The bigger story sits underneath the price chart. Realized hashrate among a cohort of publicly traded Bitcoin miners fell from 368.3 exahashes per second in the fourth quarter of 2025 to 319 EH/s in the second quarter of 2026, a 13.4% decline, according to data from BlocksBridge Consulting. Strip out Bitdeer, whose own hashrate grew 44% to 63 EH/s over the same stretch, and the rest of the public miner cohort saw a steeper 21.2% drop, from 324.6 EH/s to 255.9 EH/s. Bitcoin's total network hashrate fell a comparatively milder 10.6% over the same period, meaning public miners are pulling back faster than the network as a whole.

• Bitcoin held roughly flat near $63,400 over the past 24 hours, still range-bound between $62,000 and $66,000
• US spot Bitcoin ETFs saw $61.1 million in net outflows, led by FBTC and IBIT; Ether ETFs gained $7.4 million
• Public miner realized hashrate fell 13.4% from Q4 2025 to Q2 2026 (368.3 to 319 EH/s) as capacity shifts to AI hosting
• Excluding Bitdeer, the rest of the cohort's hashrate dropped 21.2%, versus a 10.6% decline for the overall Bitcoin network
• Core Scientific reported $136.7 million in colocation revenue in Q2 2026, versus $27.5 million from Bitcoin mining; TeraWulf reported $31.9 million in HPC lease revenue versus $12.8 million from mining

The pattern behind those individual company numbers is now a sector-wide trend: miners with access to power and data-center capacity are finding AI hosting contracts more lucrative than mining itself, and are reallocating hardware and real estate accordingly rather than expanding ASIC fleets. TeraWulf's own $19 billion hosting deal with Anthropic illustrates the scale some of these contracts now reach, and miner stocks have rallied on the AI pivot even as the industry says it still needs tens of billions more in capital to build out the compute capacity these deals require. For Bitcoin's security budget, the tension is straightforward: less hashrate dedicated to mining doesn't threaten network security on its own, since difficulty adjusts, but it does mean a growing share of publicly traded miners' economics no longer depends on the price of Bitcoin at all. That's a meaningful change in how to read miner stock moves going forward: a rally or selloff in mining-sector shares increasingly reflects AI hosting demand and power-contract economics rather than Bitcoin's spot price alone.
