Shares shifted as SoftBank Group rocketed nearly 20% in Tokyo trading on May 21—its biggest single-day jump since the pandemic crash of March 2020—after back-to-back reports that two portfolio crown jewels, OpenAI and SB Energy, are headed for U.S. public listings. The rally added roughly $35 billion in market value in hours, but the real question is whether these IPOs can solve a growing cash crunch before it becomes a crisis.
Two IPOs in the Pipeline Give Investors Something Concrete to Price In
OpenAI is preparing to file for an IPO in the coming weeks, targeting a fall debut, and is working with Goldman Sachs and Morgan Stanley on a confidential filing as soon as this Friday. Separately, SB Energy, a SoftBank-backed digital infrastructure firm based in Redwood City, California, filed a confidential draft registration for a U.S. IPO, seeking to capture demand for AI data center power infrastructure. The company has raised more than $1.8 billion from SoftBank, OpenAI, and Ares Management. Two IPO filings in one week signals that SoftBank is shifting from accumulating AI assets to harvesting them.
SoftBank's ~$110 Billion OpenAI Stake Is Enormous—but It's Still Paper Money
SoftBank's total OpenAI commitment stands at roughly $64.6 billion for an approximately 13% stake.
At OpenAI's $852 billion valuation, that stake is notionally worth roughly $110 billion. Yet S&P Global shifted SoftBank's outlook to "negative" in March, citing concerns that the gains remain paper profits in a private entity while the company has taken on substantial debt. An IPO would turn illiquid shares into tradeable collateral or outright cash—exactly what Son needs.
A $32 Billion Funding Gap Makes These Listings Urgent, Not Optional
CreditSights estimates SoftBank faces a $32 billion funding shortfall, including bond maturities over the next two years and commitments like a $5.4 billion acquisition of ABB's industrial robots unit.
A $40 billion bridge loan matures by March 2027, meaning SoftBank must replace that short-term borrowing through asset sales, bonds, or refinancing. The OpenAI IPO isn't just a return on investment—it's a lifeline for the balance sheet.
Nvidia's Strong Earnings Helped, but One-Stock Concentration Is the Real Risk
SoftBank's Vision Fund investment gains in the fiscal year totaled $45 billion, nearly all driven by OpenAI, while the firm suffered losses on other holdings such as Coupang, DiDi Global, and Klarna. That lopsided dependence means if OpenAI's IPO stumbles or its valuation compresses, SoftBank has no backup engine. Today's rally is a bet that the exit will work. The next six months will determine if it does.
