US AI DATA CENTER WEEKLY | SEPT. 21–27
$SLNH $CIFR $CLSK $CRWV $CORZ $IREN $HUT $APLD $WULF
A $9 billion Texas lease, nearly $6.5 billion in debt financing and a fresh Wall Street debate over the value of AI infrastructure.
Billions continued to flow into America's AI data center expansion this week. Cipher secured another decade of contracted revenue, CleanSpark and CoreWeave closed major financings, and UBS initiated coverage of five infrastructure developers.
Meanwhile, Oracle's New Mexico project brought construction schedules and power availability back into focus, while competing analyst reports exposed sharply different assumptions about the sector's economics.
Here are the week's developments across contracts, construction, capital markets and power.
• Cipher (
$CIFR): Extended Barber Lake's contracted lease term from 10 to 20 years, increasing expected revenue from $3.8B to over $9B. A major AI lab committed to an additional decade after Fluidstack's initial term. Data hall deliveries are now scheduled for Q4 2026 through Q1 2027, with Cipher bearing the first $359.3M in costs above the original budget.
• CleanSpark (
$CLSK): Closed a $2.276B senior secured bond offering at 7.875%, due 2031. Proceeds will help complete the Sandersville data center in Georgia, reimburse previous equity contributions and fund debt reserves.
• CoreWeave (
$CRWV): Completed a $4.2B convertible note offering due 2033. JPMorgan also upgraded the stock to Overweight, raising its price target from $120 to $125.
• Oracle / Blue Owl: Oracle issued a force majeure notice related to potential delays at Project Jupiter, the planned 2.45 GW Stargate campus in New Mexico. Its gas pipeline has encountered permitting setbacks. Oracle maintains its 2028 delivery schedule, and Blue Owl says its financial commitments remain unchanged.
• Soluna (
$SLNH): Welcomed Ben Carranza, P.E., formerly of Kinder Morgan, as Director of Community Engagement. He will oversee relationships with communities where Soluna develops and operates infrastructure, adding dedicated leadership as its development portfolio expands.
• Wall Street: UBS initiated Buy coverage on five AI infrastructure developers: Hut 8 ($143), TeraWulf ($24), Applied Digital ($38), Core Scientific ($24) and Cipher ($23). Rothschild & Co Redburn issued Neutral ratings on all five, alongside IREN ($40), while assigning Sell ratings to CoreWeave ($54) and Nebius ($84).
• Core Scientific (
$CORZ): Appointed former CyrusOne executive Jay Elms as Chief Commercial Officer. He will lead customer relationships as the company expands its high-density colocation business.
• Riot Platforms (
$RIOT): Fully repaid its outstanding Coinbase credit facility, terminating the agreement and releasing its collateral. The facility had provided up to $200M in secured borrowing capacity.
• Anthropic / Akamai (
$AKAM): Announced a seven-year, $11.6B cloud agreement focused on CPU workloads, potentially expandable to approximately $20B. Akamai estimates $5.5B in related capital expenditures, with $1.7B planned for 2026.
• US power outlook: Morgan Stanley estimates a 33 GW US data center power shortfall through 2028. Its analysis highlights developers including Cipher, Hut 8, Riot, Galaxy and TeraWulf, alongside companies supplying on-site generation and grid infrastructure.
The picture emerging from this week's announcements is increasingly complex. Long-term leases are expanding, debt markets are financing construction, and analysts are assigning very different values to the same development portfolios. Power availability, construction costs and the timing of revenue recognition remain central to the sector's economics.
