SOFTBANK Perp's 10% Bounce Follows a 12% OpenAI IPO-Delay Crash

The OpenAI IPO Delay That Cracked the Stock

SoftBank Group's Tokyo-listed shares (9984.T) fell about 12% on Friday, June 26 — their biggest intraday drop in more than three months — after the New York Times reported OpenAI is leaning toward postponing its IPO until 2027. The move wiped roughly $38 billion off SoftBank's market value in a single session and dragged other AI-linked names like Kioxia down with it.

The standoff behind the report is the real catalyst. OpenAI filed confidential S-1 paperwork on June 8 with Goldman Sachs and Morgan Stanley advising, but its bankers reportedly warned that a choppy tech tape — including SpaceX's sloppy post-listing performance — could dent appetite for a mega-listing. Advisers handed OpenAI a choice: wait until 2027 to chase a roughly $1 trillion valuation, or list sooner at a lower mark. Sam Altman has called cutting the trillion-dollar target a nonstarter. For a holding company whose stock was priced for a near-term payday, "later" is the expensive answer.

Why SoftBank Lives and Dies by OpenAI

SoftBank's OpenAI commitment is slated to reach roughly $65 billion by October, a roughly 13% stake that makes it the second-largest external shareholder behind Microsoft's ~27%. That bet is the engine behind the 2026 run: the Vision Fund carried its OpenAI position at about $79.6 billion in fair value at year-end against a $34.6 billion cost basis, and the group's market cap pushed above Toyota's last month.

An OpenAI listing is the cleanest way to crystallize those paper gains and shrink the conglomerate discount markets stamp on SoftBank. Push it to 2027 and that liquidity event slides past the financing runway SoftBank is leaning on to fund the OpenAI tranches — exactly the kind of timing mismatch that turns a paper win into a balance-sheet question. Analysts haven't capitulated; the sell-side consensus still sits at Buy. But the stock was leaning on a catalyst that just got pulled into uncertainty, and SpaceX is the cautionary tape: it debuted in June at a $1.77 trillion valuation and has since slid to around $153 from a high near $202.

The Perp Print Is a Bounce, Not a Bid

Here is the trap for anyone reading the green number in isolation: the SOFTBANK perp is up 10.27% over the trailing 18 hours, but the underlying just crashed. The HIP-3 oracle prices this market off 9984's JPY quote converted to USD, so at $41.35 the perp is sitting right around Friday's beaten-down close of about ¥6,226 (roughly ¥6,226 at a ~150 USD/JPY rate).

What the +10% actually captures is mean reversion. On a thin book — just $216k of 24h volume on this perp — the contract overshot below fair value during the panic and snapped back toward the cash close over the weekend. With the Tokyo Stock Exchange shut amid the broader AI selloff until Monday, June 29, there is no fresh price discovery in the underlying; this is a weekend bounce on light liquidity, not new bullish information. Nothing structural improved — the OpenAI timeline, the financing math, and the conglomerate discount are all unchanged. The honest read is to wait for 9984's first full session to digest the delay before treating this as anything more than a snap-back.
