In a significant move, Google has secured an agreement allowing them to purchase a 5.4% stake in Cipher Mining, a New York-based cryptocurrency data center firm. This deal, linked to a long-term infrastructure commitment, could potentially generate $7 billion for Cipher if all conditions are met.
The arrangement is connected to a decade-long leasing agreement between Cipher and Fluidstack, a UK-based company. Google has guaranteed $1.4 billion of Fluidstack’s obligations under this lease. This guarantee provides Google with the option to acquire equity in Cipher, valued at approximately $1.4 billion.
This marks the second collaboration between Google and Fluidstack within a two-month period, reflecting the increasing demand for high-performance computing needed to support rapidly expanding artificial intelligence models.
While Google invests heavily in its own data centers annually, spending billions, it has also begun to explore external options, similar to Microsoft, to secure additional capacity. This includes partnering with emerging AI cloud infrastructure providers like Fluidstack, despite their relatively short history and recent entry into the market.
Cipher Aims to Leverage Google’s Guarantee for Borrowing
Cipher has indicated that the guaranteed payments from Google will enable them to obtain additional debt financing and accelerate their expansion plans. Originally designed for cryptocurrency mining, Cipher’s data centers are well-suited to support the growing demands of AI, thanks to their infrastructure, including power, land, and cooling systems.
According to the contract, Fluidstack will pay Cipher $3 billion over the next ten years. Furthermore, the agreement includes options for two five-year extensions, which would generate an additional $4 billion in revenue. This could potentially bring Cipher’s total earnings to $7 billion, assuming all aspects of the agreement are fulfilled.
Following the public announcement, Cipher’s stock experienced a premarket trading surge of 24%. It subsequently stabilized at $14.14 by the market’s close on Wednesday. Impressively, the company’s share price has more than tripled during 2025 alone.
This is not Google’s first foray into this type of agreement. The company previously entered into a similar arrangement with TeraWulf, another former crypto-mining entity now adapting its facilities for AI hosting. That deal also involved Fluidstack and incorporated warrants allowing Google to acquire up to 14% of TeraWulf. These agreements underscore Google’s strategy: secure Fluidstack’s leases, gain equity in the hardware providers, and obtain priority access to cloud resources without the need to construct additional data centers.
Earlier this year, Fluidstack announced its participation in a €10 billion ($11.8 billion) supercomputer initiative in France. While the project’s progress remains to be seen, Fluidstack is clearly aiming to become a prominent supplier of AI computing power, despite its limited history in the field.
Alphabet’s Focus on AI Drives Stock Value Upward
Alphabet, the parent company of Google, holds a strong position near the top of the technology market. The company’s current market capitalization is just under $3 trillion, placing it behind only Nvidia ($4.3T), Microsoft ($3.79T), and Apple ($3.74T). Shares have seen an increase of over 30% in 2025, representing a rise of over 70% since April. This growth has surpassed the Nasdaq 100 Index, which has risen by 17% year-to-date.
Analyst Michael Nathanson from MoffettNathanson suggests that Alphabet should be considered a serious contender for the top spot. “The convergence of market dominance, diversification, and scale positions Alphabet not only as a leader in the GenAI revolution but as a company that should rightfully be considered for the title of most valuable company in the world,” Nathanson stated. He increased his price target for Alphabet’s stock from $230 to $295, close to the $300 Street-high, while maintaining a buy rating. He emphasized the company’s strengths in multimodal search capabilities and its ability to rapidly deliver innovative AI tools.
Investors are also experiencing greater confidence following Alphabet’s successful navigation of a significant antitrust challenge earlier this month. A U.S. judge declined to mandate the sale of its Chrome browser, thus eliminating a major legal threat that had loomed over the company for years. This legal victory complements a positive second-quarter earnings report, in which revenues were boosted by sales of AI-related products.
Nathanson further commented that Google’s overall GenAI strategy has shifted to a more proactive approach. “No longer cautious, Google has accelerated its GenAI product cycle, aggressively launching new products. We see this as a turning point: moving from reactive to proactive, and now dictating the pace of innovation.”
