- Bitcoin mining difficulty has fallen below year-ago levels for only the second time, dropping 19% from its all-time high as miners pivot to AI and face low hashprice.
- Texas miners helped the grid avoid blackouts during record demand, but the shift toward AI data centers is eroding that flexibility, prompting a state audit that makes approved energy capacity more valuable.
- Russia bans mining in Moscow and Kursk from August 2026 to 2032, while Kazakhstan launches a voluntary program where miners give 10% of BTC to the state in exchange for cheap electricity.
- Major mining firms like Core Scientific and Ionic Digital are rapidly transitioning to AI hosting, with Core Scientific now generating 83% of revenue from co-location rather than mining.
The Bitcoin mining industry is navigating one of its most turbulent periods in history. A combination of falling difficulty, shifting energy economics, and a massive pivot toward artificial intelligence is reshaping the landscape. Meanwhile, regulators in key regions are imposing bans or creating new incentives, adding another layer of complexity for operators worldwide.
Over the past few months, the network’s mining difficulty has dropped below its year-earlier level for only the second time ever, signaling a significant reduction in computational power competing for blocks. This decline is driven by weak mining profitability, low Bitcoin prices, and a growing exodus of capital and energy toward AI infrastructure. At the same time, Texas miners—once hailed as grid stabilizers—are losing their flexibility as they convert facilities to serve AI workloads, while Russia and Kazakhstan take opposite regulatory approaches.
Bitcoin Mining Difficulty Plunges as Economics Shift
The difficulty metric, which adjusts every 2,016 blocks to keep block times around 10 minutes, now sits at 126.23 trillion—about 1.1% below the 127.62 trillion recorded a year ago and 19.1% below the all-time high of 155.97 trillion from November 2025. This marks only the second year-over-year decline in Bitcoin’s history, the first being after China’s 2021 mining ban. According to Luxor’s Hashrate Index, the current drop is rooted in mining economics: falling Bitcoin prices, reduced revenue per hash (hashprice), and a diversion of resources toward AI and high-performance computing. The hashprice hit a low of $27.66 per petahash per day in late June, just a cent above its February minimum, before recovering slightly to $31.7. Futures markets suggest miners expect little improvement for the rest of 2026, with average hashprice contracts at $31.85 per petahash per day through December.
The hashrate has fallen 12% from its peak of 1 ZH/s, and an estimated 15–20% of the global mining fleet is operating at a loss. Miners sold over 32,000 BTC in the first quarter of 2026—a record that surpassed all of 2025 and the Terra-Luna crisis—as companies like Riot Platforms, Core Scientific, and MARA liquidated reserves to cover costs and debt. This capitulation is the longest in Bitcoin’s history, extending 287 days, and reflects a structural shift rather than a temporary dip.
Texas Miners: From Grid Saviors to AI Converts
In Texas, Bitcoin miners have played a crucial role in stabilizing the state’s isolated power grid. During two record demand days in July—peaking at 91,308 MW on July 22—ERCOT avoided calling for conservation thanks to miners quickly shutting down operations. These facilities participate in demand-response programs, earning credits for reducing consumption during peak hours. Riot Platforms reported $21 million in such credits last year. However, the tide is turning as many mining sites convert to AI data centers. AI workloads cannot tolerate sudden shutdowns, turning flexible loads into rigid ones. This shift erodes the very buffer that helped Texas avoid blackouts.
Governor Greg Abbott recently ordered an audit of all data center projects in the state, prompting ERCOT to pause its “Lot Zero” interconnection process. Bernstein analysts note that this will slow speculative development and make already-approved energy capacity more valuable. Companies like Cipher Digital, CleanSpark, and Core Scientific are seen as beneficiaries, while Terawulf, Riot, and IREN also gain from their existing approved capacity. The audit could create a scarcity premium for megawatts already connected, as new projects face delays and political headwinds. Bernstein gave “Outperform” ratings to several miners, highlighting that the 8 GW of energy capacity contracted by miners with hyperscalers and AI firms represents over $160 billion in potential value.
Regulatory Waves: Russia Bans, Kazakhstan Embraces
Russia is taking a hard line on mining. Starting August 15, 2026, a ban will be in effect in Moscow, the Moscow region, eight districts of Kursk, and the city of Lgov, lasting until December 31, 2032. The government cites risks to the power grid, including uncontrolled energy consumption and strain on infrastructure. The move follows a broader trend of regional restrictions in Dagestan, Chechnya, and Irkutsk. Violators could face criminal liability as the Duma advances a bill on illegal mining. This forces miners to relocate to more permissive regions or countries.
In contrast, Kazakhstan is rolling out a voluntary program that turns miners into state partners. From August 1, 2026, qualified mining companies can hand over 10% of their monthly Bitcoin production to the government. In return, they get access to regulated electricity tariffs guaranteed for 10 years. The National Investment Corporation will manage the assets, aiming for a sovereign reserve of $500 million to $1 billion in digital assets. This model aligns mining with national energy policy, providing predictability for both miners and the grid. The success hinges on Bitcoin’s price and miner participation, but it could set a precedent for other resource-rich nations.
Meanwhile, Malaysia continues its crackdown on illegal mining. Authorities dismantled three clandestine operations in Perak, arresting two men and seizing 73 ASIC miners. The facilities were stealing electricity from the national grid, a recurring issue that costs the state utility millions annually. Such enforcement highlights the ongoing challenge of unregulated mining in regions with subsidized power.
Mining Companies Pivot to AI Infrastructure
The most profound transformation is the industry’s pivot toward artificial intelligence. Core Scientific, once a pure Bitcoin miner, now generates 83% of its revenue from co-location services for AI clients. A recent deal with AMD includes warrants to buy up to 30 million shares at $23.47, and the company’s contracted capacity has grown to 1.1 GW, representing over $24 billion in potential revenue. Core Scientific’s mining revenue plunged 66% year-over-year to $21.5 million in Q2, while co-location brought in $136.7 million. The firm also resolved a chip purchase agreement with Block, taking a $41.9 million charge.
Ionic Digital, born from Celsius Mining’s bankruptcy, debuted on Nasdaq under ticker IOND. In Q1 2026, it earned $44 million from leasing digital infrastructure and only $7.4 million from mining. Its 234 MW facility in Texas is leased to Nscale for high-performance computing under a 126-month contract. The company holds $34.9 million in cash, $192.1 million in crypto, and no debt, but faces the challenge of convincing Celsius creditors to hold shares in a firm transitioning away from mining.
Other miners like Hut 8, TeraWulf, and IREN have signed multi-billion-dollar AI contracts. TeraWulf now generates more revenue from AI than from mining. These deals offer predictable, long-term income (up to 15 years) but require heavy upfront investment. Analysts warn that firms underestimating these costs could get caught between a declining mining business and an incomplete AI infrastructure.
All these developments point to a fundamental restructuring of the Bitcoin mining sector. The combination of low hashprice, high energy costs, and the irresistible pull of AI is driving miners to abandon their original business model. Regulators are responding with bans or incentives, while Texas’s audit could further concentrate value in the hands of operators with approved power. The industry is no longer just about mining Bitcoin—it’s about who can best leverage energy assets for the highest return, whether that’s securing the grid, hosting AI, or selling hashpower. The next few years will determine whether mining remains a standalone industry or becomes a stepping stone to something else entirely.
