SoftBank Group Corp. shares rise sharply in Tokyo trading, with multiple reports citing renewed market optimism around potential IPOs tied to OpenAI and SB Energy. Bloomberg says the stock reaches a record high as investors focus on the value of SoftBank’s stakes and the possibility of large returns if major companies within its portfolio proceed to public offerings.

Bloomberg (Technology) attributes the move to hopes of big gains from SoftBank’s holdings in OpenAI and SB Energy Corp., specifically if both are listed in the future. Bloomberg (Markets) links the surge to a report that OpenAI is preparing to file for an initial public offering, which contributes to the near-term momentum in SoftBank’s share price.

Other outlets report a similar magnitude of gains, with shares described as jumping around 20%. Seeking Alpha frames the move as a reaction to the “OpenAI and SB Energy IPO pipeline.” The Economic Times also reports a sizable rally alongside expectations for IPO-related developments involving OpenAI and SB Energy. Across sources, the common factor is market anticipation of future listings connected to SoftBank’s key investments.
