Argentina has unveiled a letter of intent with OpenAI and local partner Sur Energy to explore a hyperscale artificial-intelligence data-center campus in Patagonia, a proposal that could reach up to $25 billion in staged investment and as much as 500 megawatts of computing capacity.
Branded “Stargate Argentina,” the plan would seek benefits under the country’s large-investment regime (RIGI), which offers long-term tax, customs and foreign-exchange stability to attract capital for strategic projects.
Officials emphasize this is an early-stage commitment, not a final investment decision, and no site has yet been chosen.
Patagonia is under evaluation for practical reasons: abundant wind and hydro resources, space for new high-voltage transmission, a cooler climate that cuts cooling costs, and multiple long-haul fiber routes connecting the Atlantic and Pacific.
The government has framed the initiative as part of “OpenAI for Countries,” a program designed to deliver sovereign AI services with in-country compute and tighter data controls for public agencies and regulated industries.
Industry watchers expect a major cloud operator to join the venture so the facility can sell capacity at scale, with OpenAI positioned as an anchor customer. The timing intersects with Argentina’s financial agenda.
Stargate Argentina Tests AI Ambition and Energy Capacity
Days before the announcement, Washington unveiled a $20 billion currency-swap framework and initiated direct purchases of pesos to steady markets ahead of Argentina’s October 26 legislative elections, easing short-term pressure but underscoring the broader challenge of financing long-dated infrastructure.
Turning the headline numbers into steel and silicon will require a long to-do list: environmental and construction permits, power-purchase agreements, grid interconnections, water and cooling solutions, and bankable project finance.
Reliable, competitively priced electricity is the gating factor for hyperscale AI everywhere, and Argentina will need to prove it can deliver at scale.
If realized, Stargate Argentina would be one of Latin America’s most ambitious digital-infrastructure projects, drawing suppliers, high-skill jobs and exportable AI services.
For users across the region, local compute would reduce latency and expand access to advanced models. The promise is large, but so are the execution risks—and those will decide whether Patagonia becomes the Southern Cone’s first true AI megahub.
