Nvidia is buying an additional $1.5 billion worth of shares in SB Energy Inc., a data center developer backed by SoftBank Group, ahead of the company’s planned US initial public offering. The purchase is described as taking place before the IPO, with further details tied to the offering price.

Across outlets, Nvidia’s deal terms are presented as closely linked to the IPO valuation. One report says the shares are bought at 90% of the IPO price, and that the transaction brings Nvidia’s total backing of SB Energy to $3 billion. Other coverage places emphasis on SB Energy’s pipeline and geographic footprint, noting that it has capacity in the US state of Texas as well as Ohio, tied to contracts or projects under construction.

The reporting characterizes the investment as part of Nvidia’s broader exposure to data center buildout, while reflecting SB Energy’s development schedule and capacity plans beyond the immediate IPO timeline.
