Search engine giant Google has emerged as the quiet architect behind Bitcoin miners' rapid pivot to artificial intelligence (AI).
The Alphabet-owned company provided at least $5 billion in disclosed credit support behind the AI projects of a handful of BTC miners in exchange for acquiring mining companies.
Although the market often frames these announcements as technology alliances, the underlying structure is closer to credit engineering.
Google's support will help reframe these previously unrated mining companies as trading partners that lenders can treat more like infrastructure sponsors than pure commodity producers.
The mechanics of these transactions are very simple.
BTC miners contribute to energized land, high voltage interconnections, and shell buildings. Fluidstack, a>TeraWulf, has established a structural precedent at its Lake Mariner campus in New York.
Following the initial phase, the miner announced a major expansion, bringing total contracted capacity to over 360 megawatts. TeraWulf values the deal at $6.7 billion in contract revenue, which could reach $16 billion with the extension.
Importantly, the terms of the deal show that Google increased its backstop to $3.2 billion and raised its stake derived from warrants to about 14%.
Notably, Google's role was also evident in Cipher Mining's AI axis.
Cipher Mining had a 10-year, 168-megawatt AI hosting agreement with Fluidstack for its Barber Creek site.
Cipher is touting this as approximately $3 billion in contract revenue, but the financial driver is Google's agreement to backstop $1.4 billion in lease obligations.
In exchange for this credit wrap, Google received stock warrants convertible into approximately 5.4% of Cipher's equity.

The total contract value will reach $7 billion. Market sources and company disclosures confirm that JPMorgan and Goldman Sachs are structuring the project financing, a feat made possible because Google is “financially backing” the lease obligations.
Why AI leasing beats Bitcoin margin
These structural pivots of miners respond to the deterioration of the mining economy.
According to data from CoinShares, the average cash cost to produce 1 BTC among listed miners is around $74,600, with the total cost including non-cash items such as depreciation coming to nearly $137,800.
With BTC trading at around $90,000, profit margins for pure miners continue to be compressed, prompting boards to seek more stable revenue streams.
That quest now points to AI and high-performance computing. CoinShares reported that public miners announced over $43 billion in AI and HPC contracts in the past year.
Through these deals, BTC miners can gain a better position vis-à-vis financial institutions, as banks can underwrite 10- or 15-year AI capacity leases as recurring revenue and test them against debt service coverage ratios.
In contrast, Bitcoin mining revenues fluctuate depending on network difficulty and block rewards, but most institutional investors are reluctant to settle into this pattern.
However, Google's role is to fill this gap. As a credit enhancer, it reduces the perceived risk of the project and allows miners to access capital closer to traditional data center developers.
For Google, this structure improves capital efficiency. Bitcoin miners have traditionally optimized for the cheapest and most easily reduced power they can secure, instead of incurring the full cost of construction. In contrast, AI customers expect input into building AI. This approach avoids merger considerations associated with large asset purchases.
However, if this template spans multiple campuses, critics could argue that Google has created a kind of “virtual utility.” The company won't own the buildings, but it will decide who can deploy large-scale computing on those grids.
As a result, regulators may ultimately ask whether long-term control of AI capabilities, even through leases, merits increased antitrust scrutiny.
In the case of Bitcoin, the trade-off is simple. Every megawatt diverted from mining to AI reduces the pool of power available to secure the network.
The market once thought that hashrate would follow price almost linearly as more efficient rigs and more money came online.
Therefore, as the most efficient operators systematically redeploy their best sites into AI contracts, hashrate growth becomes more constrained and more expensive, leaving a large portion of block production in stranded or low-quality power assets.
