The Globe and Mail reports in its Wednesday, May 27, edition that SoftBank Group is preparing initial public offerings for its energy developer SB Energy and autonomous robotics spinout Roze, as founder Masayoshi Son intensifies the company's push into AI infrastructure. A Reuters dispatch to The Globe reports that SoftBank has hired JPMorgan, Goldman Sachs, Morgan Stanley, Citi and Mizuho for SB Energy's IPO, which could come as early as September, the sources said. SB Energy could seek a valuation of more than $50-billion (U.S.) in its market debut. At the same time, SoftBank has tapped Goldman Sachs, JPMorgan, Mizuho and Morgan Stanley for the IPO of its autonomous robotics company Roze, which will focus on building data centres and using robotics to improve the efficiency of AI infrastructure construction and is targeting a similar time frame, the sources added. It's shaping up as a major year for IPOs, with a wave of mega AI listings, including SpaceX, Anthropic and Microsoft-backed OpenAI, expected to test investor appetite for large new issues. The Financial Times reported in April that SoftBank was exploring a roughly $100-billion (U.S.) AI and robotics spinoff and taking it public under the name Roze.
