Shares of SoftBank Group jumped 11.8% to $18.55 on August 7, capping a blistering 31% rally from the July 29 low of $14.18, as investors bet that upcoming quarterly results and a broadening AI narrative will validate the conglomerate's pivot from startup casino to infrastructure powerhouse. SoftBank Hits Record Asset Values and Bets Billions on AI Infrastructure — But Is the Stock Still Cheap Enough to Reward Latecomers?
Shares of SoftBank Group surged 11.8% to $18.55, extending a 31% rally from last week's lows, as investors digested blowout Q1 results and an aggressive push into AI cloud services. The question now: whether a conglomerate trading at a steep discount to its own asset value can sustain momentum — or whether that discount exists for good reason.
A ¥72 Trillion Asset Pile Driven by a Handful of Bets
SoftBank reported a record net asset value (NAV — essentially what its holdings are worth minus debts) of ¥72.3 trillion ($445 billion) as of June 30, powered by huge gains in its Arm Holdings chip-design stake and Intel position.
Net income of ¥347.3 billion ($2.2 billion) crushed analyst forecasts of ¥120 billion, though the beat was driven by a ¥1.3 trillion paper gain on Intel stock, not by its marquee OpenAI investment. The risk: the pro forma NAV already shrank to ¥58.3 trillion by August 5 — a ¥14 trillion drop in five weeks — exposing how volatile this portfolio truly is.
The Telecom Unit Is Quietly Becoming an AI Cash Machine
SoftBank Corp., the telecom subsidiary, posted record Q1 revenue of ¥1.81 trillion, up 9.4% year over year.
Its cloud and AI division grew 31% to ¥77.1 billion, and management doubled its growth target to a 30% compound annual rate through fiscal 2027. This matters because the telecom unit generates real, recurring cash — a stabilizer against the group's paper-gain-heavy investment arms.
A New U.S. Cloud Venture Raises the Stakes — and the Spending
SoftBank is launching a new entity to rent AI computing power to U.S. companies, targeting 10 gigawatts of data-center capacity by 2030 — competing directly with specialized cloud rivals. Meanwhile, its OpenAI commitment is projected to reach $64.6 billion by October, and cash reserves shrank 34% to ¥2.3 trillion as spending accelerated.
The Discount Is Narrowing, but Concentration Risk Looms
The market currently prices SoftBank at a 46% discount to its stated NAV , partly because Arm and OpenAI alone account for roughly 65% of total asset value.
One analyst sees ADRs reaching $19.50 in a base case and $22 in a bull scenario — but that assumes markets stay cooperative and debt costs don't bite harder. At $18.55, the stock is approaching that base case fast, leaving little margin for error.
