Blackstone Digital Infrastructure Trust filed for a $1.75 billion US initial public offering, the first pure-play data-center REIT to test public markets since hyperscale AI demand separated infrastructure winners from legacy tower operators. The filing arrives eleven months after Blackstone seeded the vehicle with $16 billion in assets transferred from its private infrastructure funds, a structure that lets limited partners take liquidity while the firm retains operating control and fee streams on the underlying facilities.
The trust holds 27 hyperscale campuses across North America and Europe, with 89% of revenue tied to contracts longer than 10 years and a tenant base weighted toward the six US cloud providers accounting for 68% of global AI compute spend. Weighted average lease duration sits at 13.2 years. The portfolio generated $1.1 billion in trailing twelve-month revenue with an EBITDA margin near 74%, a profile that separates it from American Tower and Crown Castle, where margins compress below 60% and tenant churn runs higher.
The filing matters because it prices the spread between legacy infrastructure and AI-dedicated capacity. Digital Realty and Equinix trade at forward FFO multiples near 18x, but their portfolios blend colocation, interconnection, and pre-AI builds where power density averages 6-8 kilowatts per rack. Blackstone's campuses were architected for 30-50 kilowatts per rack, with power purchase agreements already securing 2.1 gigawatts of utility capacity and another 1.4 gigawatts in development. That gap—between retrofitted assets and purpose-built AI infrastructure—is what the IPO will quantify in basis points. If the deal prices at a 15-20% premium to legacy REIT multiples, it establishes a pricing floor for the $80 billion in private data-center equity raised since 2021 that has not yet marked to public comparables.
The structure also telegraphs Blackstone's calculus on LP liquidity preferences. The firm is not selling operating companies; it is syndicated a yield vehicle that throws off predictable cash while Blackstone retains the development pipeline and fee income. The trust's 4.2% projected dividend yield slots between DigitalBridge's 5.1% and Equinix's 1.8%, a middle lane designed for pension allocators who need infrastructure exposure without venture-style power delivery risk. The filing lists $640 million in near-term development capex, but none of it is speculative—every megawatt has a signed lease or letter of intent from a tenant already burning capital on H100 clusters.
Operators should watch two follow-on events: whether KKR or Brookfield file competing REIT structures within 90 days, and whether Blackstone uses IPO proceeds to acquire 1-2 gigawatt campuses in secondary markets where utility congestion is forcing hyperscalers to consider Texas, Arizona, and Scandinavia over Virginia and Iowa. Both moves would confirm that public markets are now the cheapest capital source for AI infrastructure, a reversal from the 2019-2022 period when private equity outbid REITs on every meaningful data-center portfolio.
The filing went effective the same week that Microsoft disclosed $80 billion in fiscal 2025 capex, 70% of which funds data-center construction and power contracts. Blackstone is not betting on AI. It is pricing the infrastructure already built for customers who have no choice but to expand.
