SoftBank’US$36.7B data centre group slows IPO
SoftBank’s US data-centre developer SB Energy — targeting a ~$50bn IPO despite no operating data centres, and backed by SoftBank, OpenAI and Nvidia — has slowed its listing timeline amid market fears about AI demand, and also faces lukewarm interest in a potential ~$4.9bn debt sale (investors pencilling ~10% yields / junk-like pricing). It becomes the second AI-infra hopeful in a week to stumble after Holtec International delayed its IPO ≥3 months citing a “perfect storm” of adverse AI data-centre sentiment. Investors worry Anthropic/OpenAI safety slowdowns could cut compute demand even as Anthropic prepares its own IPO, plus political backlash and possible new regulation. SB Energy still intends to list and is watching conditions; NYT first flagged the delay. Filings show Nvidia spent $1.5bn in August buying shares at a 10% discount to eventual IPO price and will buy another $1.5bn at the IPO price ($3bn total). Heavy OpenAI customer concentration is flagged as a risk given OpenAI’s listing delay and talks for a ~$1.2tn private round — SoftBank has committed >$60bn to OpenAI. Nvidia’s up-to-$105bn Ohio campus backstop (OpenAI 20-year lease) remains central; prospectus warns fulfilling contracts needs ~$174bn investment, mostly project debt, with equity holders subordinate and no cash dividends before 2029.
Why it matters
Live capital-markets stress test for European and US AI-infra sponsors after Holtec: SoftBank’s SB Energy ~$50bn IPO pause plus junk-leaning ~$5bn debt colour, Nvidia’s $3bn pre-IPO stake and OpenAI-tenant concentration show whether the AI power/build story still clears public markets — a direct read for Dealroom-tracked infra IPOs and SoftBank/OpenAI funding cascades.
Executive takeaways
Timeline slip: SB Energy slows ~$50bn IPO waiting for AI data-centre sentiment to steady; still intends to list (NYT first). | • Peer chill: Holtec delayed ≥3 months last week — second AI-power/infra float wrongfooted in a week. | • Debt colour: talks on ~$4.9bn debt with ~10% expected yields (junk-like); company says focus on IPO then debt after. | • Nvidia skin: $1.5bn Aug purchase at 10% IPO discount + $1.5bn at IPO price = $3bn. | • OpenAI knot: customer concentration + OpenAI IPO delay / ~$1.2tn private talks; SoftBank >$60bn OpenAI commitment; Nvidia ≤$105bn Ohio residual support. | • Capex warning: ~$174bn to fulfil contracts; mostly project debt; covenants bar cash dividends before 2029.
What Financial Times may be missing
No on-record SoftBank/SB Energy confirmation of the slowdown beyond anonymous sources; limited detail on exact revised IPO window, bookrunner status, or how much of the ~$4.9bn debt was soft-circled vs abandoned. Thin Europe/Asia LP allocation angle; little modelling of how much an Anthropic/OpenAI safety slowdown would actually cut contracted MW vs PR. Equity-vs-project-debt waterfall for IPO buyers left mostly to prospectus caveats.
