Nvidia recently bought an additional $1.5B in shares to support the offering, though SB Energy remains substantially dependent on OpenAI, which leases the Milam County and 8GW PORTS-Pike campuses. The developer currently has 8.8GW of capacity contracted or under construction involving $178B in capex and a projected $439B revenue backlog over roughly 20 years starting in 2028.
