TOKYO, Sept 15 (Reuters) - Data centre developer SB Energy SBE.O, backed by SoftBank Group 9984.T, will sell up to $500 million in shares to Japanese investors as part of a public listing in the U.S., a filing showed on Tuesday. 
The firm will issue new shares to the Japanese investors, and the funds will be used for general operating costs for developing data centres, power generation and related infrastructure projects, the filing said.
The filing did not reveal the size of the U.S. IPO. SoftBank may seek a valuation of $50 billion for SB Energy, Reuters has reported.
Chipmaker Nvidia NVDA.O has committed to invest $1.5 billion in a private placement at the IPO price, and OpenAI has been issued warrants worth roughly $5.5 billion, SB Energy reported in its investment prospectus, released earlier in September. 
Investor enthusiasm for artificial intelligence has prompted a wave of public listings in related firms this year, with SpaceX SPCX.O listing in June and Anthropic preparing to list later this year.
Japanese investors secured $2.2 billion of SpaceX shares in its IPO.
