SoftBank rallies on OpenAI and SB Energy IPO plans; its Japanese-traded stock notches best day since 2000
SoftBank shares skyrocketed in Tokyo trading, notching their biggest daily gain since 2000, boosted by news about planned IPOs at OpenAI, in which SoftBank has a sizable stake, and SoftBank’s own SB Energy unit. ADRs of SoftBank traded in the US rallied, too.
OpenAI is accelerating the timeline to its public debut, preparing to confidentially file its IPO prospectus with regulators as early as Friday, according to The Wall Street Journal. That could set the stage for a highly anticipated public listing as early as September.
SoftBank has systematically expanded its financial exposure to OpenAI, securing a highly valuable stake in the company. As of the fiscal year-end, SoftBank’s cumulative investment in OpenAI totaled $34.6 billion, with a fair value of $79.6 billion, and cumulative investment gains totaled $45 billion, according to a SoftBank filing.
For SoftBank, a successful public debut is critical to demonstrating that OpenAI can protect its market position amid intense industry pressure. Investors have grown increasingly anxious that OpenAI is losing ground to competitors like Anthropic, which is currently in talks for a funding round that could push its own valuation past that of OpenAI.
Adding to the upward momentum, SB Energy, the digital infrastructure and clean energy development firm co-owned by SoftBank and Ares Management, confirmed its own confidential draft registration filing for a major US public listing.
This multipronged IPO pipeline has boosted investors’ confidence in billionaire founder Masayoshi Son’s high-conviction AI thesis, showcasing a road map for SoftBank to transition its paper gains into potential liquidity. SoftBank’s stock is up 37% so far this year.
