SoftBank Group Corp. said it’s taking longer than anticipated to get Stargate off the ground, conceding for the first time that the $500 billion artificial intelligence tie-up in the US with OpenAI is bogging down.

SoftBank Group (OTCPK:SFTBY) (OTCPK:SFTBF) is the buyer taking ownership of Foxconn Technology's (OTCPK:FXCOF) electric vehicle plant in Ohio, a move intended to jump-start the company’s $500B Stargate data center project with OpenAI and Oracle (NYSE:ORCL),

SoftBank, which has struggled to create a financial plan for Stargate, approached Foxconn to get the Apple supplier on board with its plan to build data centers and related infrastructure throughout the U.S., which led to the sale of the plant, the report said, citing people familiar with the matter.
