Public Bitcoin miners spent $5.11 billion on capital assets during the first half of 2026 while reporting only $341.2 million in artificial intelligence and high performance computing revenue, according to an Aug. 20 analysis from BlocksBridge Consulting.
Summary
- Nine public Bitcoin miners spent $5.11 billion on capital assets during first half of 2026 collectively.
- Their directly reported AI and HPC revenue totaled $341.2 million, creating a fifteen-to-one spending-to-revenue ratio overall.
- AI and HPC revenue reached $205.8 million in Q2, rising 52% from the preceding quarter collectively.
- Fifteen miners and data center companies spent $30.7 billion in their latest 2026 reporting periods already.
- CoinShares expanded WGMI’s mandate across mining, data centers, semiconductors, power generation and advanced computing companies.
The figures produce a roughly 15 to 1 ratio between companywide capital spending and directly reported AI and HPC revenue. They show how much infrastructure miners are building before their newer operations reach full commercial capacity.
The comparison does not measure returns on AI investments alone. BlocksBridge included purchases and allocations involving hardware, property, equipment and other productive assets. Some spending may continue supporting Bitcoin mining operations.
Bitcoin miners face a costly infrastructure conversion
BlocksBridge examined nine comparable miners that disclosed AI or HPC revenue. Their combined revenue from those operations reached $205.8 million in the second quarter, up 52% from the previous quarter.
The increase implies first quarter revenue of approximately $135.4 million. Core Scientific, TeraWulf and Bitdeer were among the companies reporting higher revenue from data center hosting or AI computing services.
Mining facilities offer access to land, electricity and grid connections. However, those assets do not automatically meet the technical requirements of AI customers.
“Power contracts and available land may give miners a starting advantage, but converting those assets into AI-ready capacity requires substations, buildings, cooling systems, networking equipment and, in some business models, GPUs,” BlocksBridge said in its report.
These projects also require financing before tenants begin paying for capacity. Construction schedules, power availability and customer concentration can therefore affect how quickly miners recover their investments.
AI revenue is growing from a low starting point
Core Scientific provides one example of that growth and spending pattern. The company reported $136.7 million in second quarter colocation revenue, up from $77.5 million in the preceding quarter. Capital expenditure reached $797.5 million during the same period, according to its filing.
Core Scientific said it was billing customers for 437 megawatts of capacity by mid July. It also announced agreements with AMD that could eventually cover about 530 megawatts across five sites. The company described the contracts as carrying more than $14 billion in “potential” base revenue over 15 years.
TeraWulf has moved further toward recurring data center income. As crypto.news reported, HPC revenue overtook Bitcoin mining revenue at the company during the first quarter of 2026.
TeraWulf’s regulatory filing said HPC leasing represented most of its quarterly revenue for the first time. However, its planned facilities still depend on construction milestones, tenant demand and the delivery of contracted computing capacity.
Broader capital spending reached $30.7 billion
BlocksBridge’s wider group of 15 miners and AI data center companies spent $30.7 billion on capital assets during their latest 2026 reporting periods. The total was 42.6% above the $21.53 billion recorded across all of 2025.
The comparison includes companies at different stages of development. It should therefore be treated as a measure of sectorwide investment rather than a direct assessment of profitability.
Other miners are financing the transition through asset sales and balance sheet changes. In related coverage, MARA Holdings sold $1.5 billion of Bitcoin during the first quarter as it expanded its digital infrastructure strategy.
HIVE has followed a smaller expansion model. The company’s HPC revenue increased 94% to $19.5 million during its 2026 financial year, although mining remained its main revenue source.
CoinShares expands WGMI beyond Bitcoin mining
The transition has also reached investment products. CoinShares renamed WGMI as the CoinShares Bitcoin Mining and Digital Power ETF and expanded its eligible investment universe.
The actively managed fund now covers Bitcoin miners, data center operators, AI semiconductor companies, power producers and advanced computing businesses. CoinShares reported 29 holdings and approximately $225.6 million in assets as of Aug. 18.
WGMI must invest at least 80% of its net assets in qualifying companies, according to the fund’s official page. It does not hold Bitcoin directly or through derivatives.
The next tests will be whether miners deliver new capacity on schedule, secure creditworthy tenants and convert contracted power into recurring revenue. Until then, the expanding revenue base remains small compared with the capital committed to the transition.
