Cipher Extends Texas AI Data Center Leases to 20 Years
A $5.2 billion agreement extension locks in long-term compute capacity and shared infrastructure costs in Texas
Cipher Digital has extended its lease commitments with AI cloud provider Fluidstack and an unnamed AI laboratory at its Barber Lake data center campus in Colorado City, Texas, stretching site commitments to 20 years. The expanded agreements add $5.2 billion in contracted revenue, bringing total campus value to over $9 billion as demand for gigawatt-scale AI infrastructure accelerates.
Key details
The revised agreements cover the entire 300 MW power capacity and 207 MW critical IT load at the Barber Lake facility. Fluidstack amended its initial lease commitment, while an unnamed AI lab signed a binding agreement to enter a second ten-year lease immediately following Fluidstack's term.
Handover of individual data halls is scheduled between Q4 2026 and Q1 2027, driven by design updates to accommodate high-density AI rack configurations. To handle rising infrastructure capital expenditures, the deal establishes a cost-sharing framework: Cipher will absorb the first $359.3 million in cost overruns, after which the tenant will reimburse half of additional expenses through adjusted rent over the 20-year lifespan.
Why this matters
Long-term 20-year leases reflect how hyperscalers and AI cloud providers are rushing to secure multi-megawatt power capacity amidst severe grid bottlenecks across North America. By locking in site access and structuring cost-sharing provisions for capital expenditure overruns, developers and AI operators are insulating themselves from volatile hardware and utility supply chain inflation.
Context
The Barber Lake campus originally contracted 168 MW of critical IT load in late 2025 before expanding to 207 MW. Across Texas, utility operators and ERCOT are managing unprecedented interconnection requests from AI data centers. With power availability becoming the primary constraint for model scaling, long-term capital guarantees and behind-the-meter infrastructure planning have become essential for securing utility-scale compute.
What happens next
Cipher expects to commence hall handovers and rental income streams starting in late 2026 as initial site construction completes. Industry observers will monitor whether similar 20-year lease structures and cost-sharing models become standard across Texas and other high-density AI data center markets.
