Bitcoin mining companies have signed over $150 billion in multi-year AI infrastructure contracts as of July 2026, according to Bernstein's deal tracker. The figure covers more than 7.5 gigawatts of committed capacity across binding or near-binding commercial agreements with hyperscale AI companies. The shift represents the largest capital reallocation in the mining sector's history.
The pivot is not voluntary. Hashprice — the standard measure of daily mining revenue per unit of computing power — fell to approximately $29 per petahash per second per day in July 2026, an all-time post-halving low and a level not seen since the 2020 COVID crash. According to CoinShares' Q1 2026 mining report, 15% to 20% of the global mining fleet is operating at a loss. The weighted average all-in cost to produce one bitcoin, excluding non-operational accounting adjustments, has risen to approximately $240,407 — well above the spot price of roughly $64,000. Mining as a standalone business model is, for most operators, cash-flow negative.
The result is a two-track industry. Companies that control large power portfolios and grid-connected sites are converting those assets into AI data center campuses, generating contracted dollar-denominated revenue measured in decades. Companies without those assets are shutting down. Mining stocks, paradoxically, have outperformed bitcoin by approximately 70% year-to-date, driven entirely by AI infrastructure valuations rather than mining economics.
The April 2024 halving cut Bitcoin's block reward from 6.25 BTC to 3.125 BTC. The economic consequences have compounded through 2026. According to VanEck's mid-July 2026 Bitcoin ChainCheck, June miner revenue fell to an estimated $841 million, down 25% from May's $1.12 billion. July is tracking similarly weak, with approximately $322 million through the first 12 days of the month.
The hashprice metric tells the story most clearly. At roughly $29/PH/s/day, miners earn less per unit of deployed computing power than at any point since the metric has been widely tracked. CoinShares estimates that miners paying standard commercial electricity rates of $0.08 to $0.12 per kilowatt-hour have largely moved machines offline. Only operations with access to stranded or subsidized power below $0.03/kWh are generating positive cash flow from mining alone.
Network hashrate reflects the stress. After briefly crossing 1 zetahash per second (1,000 EH/s) earlier in 2026 — an all-time high — hashrate declined by more than 25% from its October 2025 peak by mid-2026. On July 11, Bitcoin's mining difficulty decreased 5% to 127.17 trillion, the 14th adjustment of the year, driven by a 7.9% decline in hashrate over the preceding ten days.
ROI for new mining hardware has stretched beyond 1,000 days — longer than the time remaining until Bitcoin's next halving. For most operators, purchasing new ASICs for the sole purpose of mining no longer passes basic capital allocation thresholds.
The mining-to-AI pipeline exists because of a structural mismatch in the data center industry. According to Goldman Sachs, US data center power demand is projected to climb from 31 gigawatts in 2025 to 41 GW in 2026 and 66 GW by 2027. However, approximately 50% of planned US data center capacity for 2026 is expected to be delayed or canceled, according to industry tracking data. Of the roughly 12 GW of new capacity expected in 2026, only about one-third is currently under active construction.
The binding constraint is not compute silicon. It is physical infrastructure: shortages of transformers, switchgear, and batteries, layered on top of limited utility power availability. Nearly 2,300 GW of generation and storage capacity sits in US interconnection queues, with wait times in many regions stretching past five years. Large power transformers face supply shortfalls of approximately 30%.
Bitcoin miners hold an asymmetric advantage in this environment. They already control large, grid-connected power portfolios. Their sites have existing utility agreements, environmental permits, and high-voltage infrastructure. Converting a mining facility to an AI data center requires significant capital expenditure on cooling and networking, but it bypasses the multi-year permitting and interconnection timeline that greenfield data center developers face.
Bernstein analyst Gautam Chhugani has described miners as "the power landlords of AI," noting that they are "best positioned to solve 'time to compute'" — the gap between when AI companies need capacity and when new-build data centers can deliver it.
The $150 billion aggregate tracked by Bernstein is concentrated among a handful of publicly traded miners. The following deals have been publicly disclosed:
TeraWulf — Anthropic: $19 billion, 20 years. TeraWulf signed a lease with Anthropic for a planned AI infrastructure campus in Hawesville, Kentucky. The agreement covers approximately 401 megawatts of critical IT load, with capacity expected to arrive in phases beginning late 2027 and reaching full ramp in early 2028. TeraWulf simultaneously agreed to sell its 50.1% stake in the Abernathy data center joint venture for approximately $530 million to free capital for owned-and-operated development. Total contracted HPC revenue for TeraWulf has reached approximately $12.8 billion.
Hut 8 — Undisclosed Hyperscaler: $9.8 billion, 15 years. Hut 8 signed a lease covering 704 megawatts of IT capacity at its Beacon Point AI data center campus in Nueces County, Texas, doubling the existing tenant's contracted footprint. Hut 8 CEO Asher Genoot told CNBC that the company had zero contracted AI revenue approximately one year ago and now counts roughly $27 billion in contracted AI revenue and about $1.75 billion in annualized EBITDA. Hut 8 shares are up approximately 128% year-to-date and have traded between $44 and $133 in 2026.
IREN — AI Developers: $2.8 billion. IREN disclosed $2.8 billion in cloud services contracts with AI developers and raised its year-end AI Cloud annualized run-rate revenue target to more than $4 billion, stating that approximately 85% of that target is already under contract.
Riot Platforms — AMD: up to $1 billion, 10 years. Riot signed a lease and services agreement with AMD covering an initial 25 MW of critical IT load, since expanded to 50 MW. The initial agreement is expected to generate approximately $311 million, with AMD options potentially bringing total contract revenue to $1 billion.
MARA Holdings — Texas Campus: up to $600 million. MARA agreed to acquire a 1,200-acre powered site in Matagorda County, Texas, from HIF USA, structured as up to $600 million in milestone-based payments. The site is expected to provide 1 GW of grid capacity by October 2027 and 2 GW by April 2028. MARA plans to develop the property alongside Starwood Digital Ventures as a dual-purpose campus for AI data centers and Bitcoin mining. The deal pushes MARA's total power portfolio to nearly 4.8 GW.
Core Scientific — AI Pivot. Core Scientific announced plans to monetize "substantially all" of its bitcoin holdings in 2026, having already sold roughly 1,900 BTC for about $175 million in January to fund its AI and HPC expansion.
The market is repricing mining companies as AI infrastructure plays. Year-to-date 2026 performance among leading public miners:
| Company | Ticker | YTD Performance | Primary AI Catalyst | |---------|--------|-----------------|---------------------| | TeraWulf | WULF | +73.6% | $19B Anthropic lease | | Hut 8 | HUT | +128% | $27B contracted AI revenue | | Riot Platforms | RIOT | +47.0% | AMD data center lease | | CleanSpark | CLSK | +25.9% | Infrastructure conversion |
Over the same period, Bitcoin has declined approximately 25% from its late-2025 peaks and traded around $64,000. The Valkyrie Bitcoin Miners ETF and comparable baskets have outperformed BTC by roughly 70% YTD, according to Bernstein.
The divergence reveals what the market is pricing: mining stocks are no longer correlated with bitcoin. They are correlated with the AI infrastructure buildout. Investors value these companies based on contracted megawatts, lease terms, and EBITDA visibility from data center operations — not on hashrate, block rewards, or BTC price forecasts.
Short interest in several mining names remains elevated, however. According to Bankless Times reporting, traders have maintained significant short positions against CLSK, RIOT, IREN, WULF, and CORZ, betting that the AI infrastructure transition carries execution risk that current valuations do not adequately reflect.
The flip side of the AI pivot is accelerated attrition among miners who lack convertible infrastructure. Industry data suggests that approximately 85% of global hashrate is now controlled by just 12 publicly traded entities or sovereign-backed operations.
Notable casualties in 2026:
The pattern mirrors what the broader crypto ecosystem experienced in H1 2026, during which approximately 70 crypto projects shut down entirely, according to industry tracking data.
The mining-to-AI pivot raises a structural question about where economic value in the Bitcoin network actually resides. The miners are not abandoning worthless assets. They are demonstrating that the most valuable component of their operations was never the ASIC chips or the mining software — it was the power infrastructure.
Grid-connected sites with utility agreements, high-voltage substations, and environmental permits represent multi-year, multi-billion-dollar assets. Bitcoin mining was, in economic terms, a placeholder use for that infrastructure during a period when no higher-value tenant existed. AI companies are now that tenant, and they are willing to sign 15-to-20-year leases at rates that dwarf what mining economics can produce.
This creates a paradox for Bitcoin network security. If the most efficient operators are rationally reallocating capacity away from mining, the network's long-term hash rate may stabilize at a lower level than peak, supported only by operators with the cheapest possible power or those who view mining as a strategic hedge rather than a primary business.
The economic value distribution is shifting: miners' infrastructure generates more value as AI landlords than as block producers. The market has noticed. Whether the Bitcoin network adapts to this new equilibrium — through fee market development, further difficulty adjustments, or protocol-level changes — remains an open question.
The Bitcoin mining industry is undergoing a structural transformation, not a cyclical downturn. The post-halving economics have compressed margins to the point where mining revenue no longer justifies the infrastructure it requires. AI demand for power has created an exit ramp that the largest operators are taking at speed.
The $150 billion in contracted deals is not speculative pipeline. It represents binding commercial arrangements with some of the most heavily capitalized companies in the technology sector. The mining companies that survive as miners will be those with the cheapest power and the longest time horizons. The rest are becoming data center landlords.
For the Bitcoin network, the implication is that security is increasingly provided by a smaller, more concentrated set of operators. Whether this concentration creates vulnerability or simply reflects rational economic behavior is a question the market has not yet priced.
