Blackstone files $1.75B data center REIT S-1, tests infrastructure yield appetite mid-cycle

Blackstone filed an S-1 registration statement for a new data center REIT targeting $1.75 billion in gross proceeds, the firm's first infrastructure-focused public vehicle since the 2019 carve-out of Tallgrass Energy. The timing places the offering inside a narrow window: hyperscale demand remains structural, but forward power costs and interconnect lead times now exceed 24 months in primary markets. The filing lists no pricing range or share count, standard for initial S-1 submissions, but the proceeds figure alone makes this the largest specialized REIT debut since Digital Realty's 2004 offering.

The portfolio consists of eleven operational facilities across six markets, with weighted-average lease terms of 8.2 years and occupancy at 91 percent. Two properties serve a single hyperscale tenant each; the remainder house colocation customers under triple-net structures. Blackstone acquired the anchor assets between 2021 and 2023, paying a blended $287 per kilowatt of critical IT load, below the $310-$340 range that defined 2023 transactions. The portfolio generated $164 million in net operating income over the trailing twelve months, implying a 10.7 percent unlevered yield at current book value. That sits 140 basis points above the public data center REIT average, though the privates typically carry more land bank optionality and less single-tenant concentration.

The filing matters because it confirms Blackstone's view that public equity markets now price infrastructure yield competitively with private perpetual vehicles, a reversal from the 2015-2021 period when the firm systematically took real estate private. Data center REITs trade at a median 5.8 percent implied cap rate today, 220 basis points tighter than in early 2023, driven by the AI compute buildout and a $41 billion wall of hyperscale capex commitments through 2026. If Blackstone prices this REIT inside 6 percent, it validates a new cost-of-capital regime for long-duration infrastructure and invites follow-on offerings from competing private managers. The alternative—pricing outside 7 percent—signals that public buyers remain skeptical of single-use assets with 15-year depreciation schedules and recontracting risk in the 2030s.

Allocators should track three developments over the next 90 days: whether Blackstone includes a share buyback authorization in the final prospectus, an unusual but telling signal of pricing confidence; whether the roadshow emphasizes contracted revenue or development pipeline, which separates yield buyers from growth buyers; and whether peer REITs—Digital Realty, Equinix, CyrusOne—revise guidance or accelerate their own equity raises in response. The filing also disclosed $480 million in trailing twelve-month capital expenditures, a 34 percent reinvestment rate that suggests the portfolio skews toward expansion-ready shells rather than fully stabilized boxes. That matters for underwriting: if half the proceeds fund tenant improvements, the effective equity raise drops to $1.3 billion and the yield story compresses.

The S-1 names Goldman Sachs, Morgan Stanley, and JP Morgan as lead underwriters, the same trio that ran Blackstone's $18.5 billion Bellagio REIT in 2019. That offering priced at the low end, traded down 11 percent in six months, then returned 43 percent over three years as the strip stabilized. The data center comp is tighter, the duration longer, and the embedded lease escalators—2.5 percent annual bumps—matter more in a 4 percent ten-year Treasury world. Blackstone has committed to retain a 15 percent stake post-IPO, a lower insider hold than typical REIT spinouts but enough to keep asset management fees internalized. The filing goes effective no earlier than mid-Q2, assuming a standard 45-day SEC review and two-week roadshow. Power futures in PJM and ERCOT, the two grids hosting nine of the eleven properties, are currently trading 18 percent above 2024 averages.
