Amazon Cipher Mining Partnership Signals $5.5B AI Shift

Key Takeaways

• The Amazon Cipher Mining partnership represents a $5.5 billion, 15-year AI hosting deal.

• Cipher Mining is transitioning from Bitcoin mining to becoming a major AI infrastructure provider.

• The Colchis data center in Texas will serve as a high-performance computing hub for AI workloads.

• AI-focused hosting contracts now total $8.5 billion, attracting significant investor attention.

• The deal exemplifies the convergence of crypto infrastructure with AI computing needs, a defining trend of 2025.

The Details Of The Amazon Cipher Mining Partnership

The agreement gives AWS access to Cipher’s upcoming data center capacity for high-performance computing.

Beginning in 2026, the deal will deploy 300 megawatts of power across both liquid- and air-cooled systems designed specifically for AI workloads. Construction and delivery are scheduled in two phases, with lease payments starting in August 2026.

Analysts say this is Cipher’s most substantial contract to date and a major milestone in its transformation from a crypto miner to a cloud and AI infrastructure provider.

Texas Emerges As A New AI Hub

Alongside the Amazon deal, Cipher announced plans to build a massive data center complex in West Texas, named Colchis. Spanning 620 acres, the site will connect directly to the American Electric Power grid via dual interconnections.

Full operational capacity is expected by 2028, pending approval from ERCOT, the Texas grid operator.

What Makes Colchis Unique

• Ownership & Financing: Cipher will control approximately 95% of the joint venture and provide most of the financing.

• Infrastructure for AI: The facility is designed to host AI training clusters, GPU farms, and other high-performance computing systems that conventional cloud providers struggle to accommodate.

This expansion positions Texas as a new battleground in the race to supply AI infrastructure, potentially rivaling traditional tech hubs in California and Washington.

From Bitcoin Mining To AI Hosting

The Amazon Cipher Mining partnership is part of a broader industry trend. Many crypto miners are transitioning from energy-intensive Bitcoin operations to providing AI computing infrastructure.

Companies with large-scale power contracts and extensive real estate have found themselves perfectly suited to support the massive computational needs of AI platforms like Amazon, Microsoft, and Google.

Cipher was among the first to pivot. In September, the company secured a 10-year, 168-megawatt hosting deal with Fluidstack, backed by a $1.4 billion guarantee from Google, earning a 5.4% equity stake in the process.

CEO Tyler Page described that deal as the company’s “turning point,” with the AWS agreement solidifying Cipher’s position as a leading AI infrastructure provider.

Financial Highlights & Market Response

Cipher’s Q3 earnings showed a net loss of $3 million, or one cent per share, but adjusted income reached $41 million. Additionally, a $1.3 billion convertible note raised new liquidity for upcoming projects.

AI-focused hosting contracts now total $8.5 billion in lease commitments, a figure comparable to the market capitalization of many mid-tier data center operators.

Investors reacted immediately to the news, with Cipher’s stock rising over 33% to $24.81, extending a year-to-date gain exceeding 400%.

AI’s Influence On Energy & Infrastructure

The Amazon Cipher Mining partnership reflects the broader AI arms race, as tech giants compete for computing power to train large language models and generative AI systems.

For example, on the same day as the Cipher announcement, Australia’s IREN signed a $9.7 billion deal with Microsoft to provide access to Nvidia GB300 GPUs.
