When OpenAI announced Stargate in January 2025, the headline number was $500 billion.
That was never $500 billion already spent. It was a four-year investment plan for U.S. AI infrastructure.
By 2026, however, Stargate had moved far enough that the more useful question was no longer whether anything had been built.
What is actually live?
OpenAI said in January 2026 that its first Stargate site in Abilene, Texas was already training and serving frontier AI systems. It also said multiple Stargate sites were under development across Texas, New Mexico, Wisconsin and Michigan.
In April 2026, OpenAI said it had surpassed the 10GW U.S. infrastructure milestone it originally set for 2029, with more than 3GW added in the previous 90 days.
Capacity is not the same as spending
Those updates still do not mean the entire $500 billion has been spent.
Gigawatts describe planned or delivered power and compute capacity. Investment figures describe capital committed or expected across land, data centers, chips, power systems, networking and other infrastructure. They are different measurements.
The project also expanded beyond the U.S.
OpenAI later announced Stargate UAE, including a planned 1GW cluster in Abu Dhabi with an initial 200MW expected online in 2026.
That expansion does not replace the original U.S. Stargate commitment. It shows that “Stargate” evolved from one financing headline into a broader infrastructure strategy.
The Robius takeaway
The 2025 article was right to flag the difference between a headline commitment and delivered infrastructure. In 2026, we can go one step further: OpenAI says real capacity is now operating, while the $500 billion figure remains a multi-year capital ambition rather than a completed spend.
