SB Energy Defers $50B IPO; Oracle CDS Spreads Triple on AI Debt Fears
The gist
Two major AI infrastructure participants are facing credit and equity market skepticism about the scale and debt-intensity of their buildout plans. The SB Energy case centers on concentrated tenant risk from a single company, OpenAI, before any operational capacity exists.
The full picture
SoftBank-majority-owned SB Energy has deferred its planned IPO at roughly $50B as investors question its $178B capital expenditure program for AI data centers. The company has no operating data-center capacity yet but has 8.8GW contracted or under construction, financed largely through project-level debt. SB Energy has acknowledged substantial dependence on OpenAI, which leases both the Milam County site and the 8GW PORTS-Pike campus. Nvidia provided a $105B conditional guarantee covering specified OpenAI lease obligations at PORTS-Pike, but that guarantee does not cover SB Energy's full construction program. Separately, Oracle's 5-year credit default swap spreads more than tripled from September 2025 through at least February 2026, with trading volumes on Oracle credit instruments surging well above prior norms, driven by concern over Oracle's highly debt-funded AI infrastructure buildout strategy, even as its core business and profitability remained strong.
