Why US A.I. Capital Is Choosing Paraguay Over Brazil for Compute

RioTimes Deep Analysis | Series: Latin America Energy and Tech Guide

A landlocked South American country of seven million inhabitants is quietly being treated by Washington and by Silicon Valley as the next strategic node of the global AI supply chain. The shift is not a marketing claim. It is the visible consequence of three converging facts: a 1973 treaty inflection that liberates roughly half of one of the world’s largest hydroelectric outputs, a tax regime that taxes industrial value added at 1%, and an investment-grade balance sheet that Brazil no longer possesses.

The Itaipu 2027 Inflection

The Itaipu Binacional hydroelectric dam, jointly owned by Brazil and Paraguay since the 1973 treaty signed under Emilio Garrastazu Medici and Alfredo Stroessner, will enter a new tariff regime on January 1, 2027. Under the prior arrangement, Paraguay was obligated to cede its unused share of the 14,000-megawatt plant to Electrobras at a compensation of around 12 dollars per megawatt-hour, well below market price; under the post-2026 framework, Paraguay can negotiate prices freely with Brazilian regulated and unregulated buyers and, increasingly, with offtakers anywhere in the world.

The numbers underlying that pivot are large. Itaipu generated 72.9 terawatt-hours in 2025, up 8.6% from the prior year, and Paraguay’s treaty allocation entitles it to 50% of total production. Local consumption ran at roughly 25 to 30 terawatt-hours in 2024, equal to 38.8% of the plant’s output.

That leaves 7 to 12 terawatt-hours of immediate surplus and a much larger pool if Paraguay redirects the share historically ceded to Brazil. Royalty and cession transfers to the Paraguayan government totaled 462 million dollars in 2025, down from 549 million in 2024 on hydrological variability. Itaipu’s Brazilian director general Enio Verri said this month that 2027 will bring “the lowest tariff in the country,” a public framing of the same transition Rio Times analyzed in coverage of Brazil’s cheap-power hope meeting Paraguay’s hard line on Itaipu after 2026.

The Brazilian negotiating team wants the post-2026 tariff stripped of “discretionary costs,” targeting roughly 9 dollars per kilowatt-month versus the current 19.28 dollars. Paraguay resists, arguing the higher tariff funds socio-environmental commitments worth around 650 million dollars per year. The arithmetic of that argument is changing fast: every megawatt Paraguay redirects from Brazil to a domestic compute customer captures the full retail margin instead of the cession compensation, and once the surplus is fully channeled into local industrial demand, the cession line disappears entirely.

The X8 Cloud Anchor and the AI.gov Strategy

The X8 Cloud Commitment

In December 2025, Los Angeles-based X8 Cloud announced what could become the largest committed foreign direct investment in Paraguayan history: an initial 250 million dollars in 2026 to install 6 megawatts of capacity and 4,000 Nvidia H100-class GPUs, scaling to 250 megawatts and over 165,000 GPUs in a second phase, and reaching a total capex envelope of 10 to 50 billion dollars over 30 years. The company’s chief executive Juan Carlos Duenas told BNamericas the project goal is 5 gigawatts of AI capacity, anchored to the Itaipu transmission corridor and a 500-kilovolt line near Asuncion. Construction begins in Q2 2026 pending regulatory sign-off, with commercial operations targeted for early 2026 at 50 megawatts and expansion to 500 megawatts in 2027.

The Washington Framework

The deal sits inside a broader Washington framework: Secretary of State Marco Rubio told the Senate Foreign Relations Committee in May 2025 that “someone smart is going to go to Paraguay and open an artificial intelligence facility,” explicitly citing the 50% Itaipu allocation no longer destined for Brazil. The Trump administration’s AI.gov initiative, the US Trade and Development Agency, US private investors and unnamed sovereign wealth funds are listed as financing partners. X8 Cloud has separately discussed an Nvidia AI factory in Paraguay, mirroring the architecture Nvidia is replicating in Saudi Arabia, the United Arab Emirates and South Korea.

The Riquelme Doctrine

Paraguay’s Industry and Commerce Minister Marco Riquelme traveled to Silicon Valley in March 2026 and met executives from Nvidia, OpenAI, Crusoe and Lambda; on his return he framed the policy thesis as a national income strategy. “Every 100 megawatts of energy has the capacity to attract 4 billion dollars in investment,” Riquelme told reporters, putting the country’s 5-gigawatt available ceiling within sight of Paraguay’s entire 45 billion dollar GDP. Hive Digital Technologies is separately expanding its Yguazu hydro-powered facility to 400 megawatts, and the Inter-American Development Bank is financing 130 million dollars in sovereign cloud and Tier III government infrastructure.

The Macro Snapshot Behind the Pitch

Paraguay’s competitive stack is real and recent. The country secured its first investment-grade rating from Moody’s in 2024, joined by S&P and Fitch within 18 months, and central bank inflation runs at 1.9% with a policy rate held at 5.5%. The macro contrast Rio Times documented in Paraguay’s 6.6% GDP outperformance is now translating into investor mandates that did not previously consider South America’s smallest mainland economy.

The legislative scaffolding hardened in 2025. Law 7547/2025 modernizes the maquila regime that taxes industrial value-added at a single 1% rate, Law 7548/2025 overhauls the 1990 investment-incentive framework, and Law 7546/2025 establishes a national policy for electronic equipment production and assembly. The maquila sector now houses 320 companies, generates 35,000 direct jobs, and produced 69% of Paraguay’s industrial exports in 2025, with February 2026 exports up 26% year-on-year at 134 million dollars in a single month.

Brazil’s Position: Scale, REDATA, and Lula’s Energy Condition

The Industrial Decline Argument

The comparison Folha de S.Paulo columnist Ronaldo Lemos drew between the two countries this weekend is provocative for a reason. Brazil’s industrial transformation share has fallen from 17% of GDP in 1994 to 11% today, its Economic Complexity Index has declined continuously since 2000, and on the ECI trajectory Paraguay will overtake Brazil within the next several years. Lemos frames the gap as one of direction rather than scale: Brazil has the same assets as Paraguay in much larger dimensions, but lacks the planning, policy stability, and macro framework to monetize them.

The REDATA Counter-Bet

Brazil is not absent from the data-center race; it is approaching it differently. Finance Minister Fernando Haddad’s REDATA program reserves 5.2 billion reais (about 1.05 billion dollars) for sector incentives starting January 1, 2026, sits alongside the 23 billion-real PBIA national AI plan, and is backed by a BNDES credit line of 2 billion reais. Lula added a sharper condition on May 7 after meeting Donald Trump at the White House, telling reporters that “anyone who wants to build a data center in Brazil has to produce their own energy, because we are not going to spend money creating data centers to send data to other countries.”

The 12th Place Gap

The position protects the domestic grid but also signals a different bet: instead of competing for hyperscale offtake of existing renewable output, Brazil wants the data-center industry to bring its own generation capacity. The architecture mirrors the 9 billion-dollar Pecem complex anchored by TikTok parent ByteDance in Ceara. Brazil ranks 3rd globally in internet connectivity and 5th in mobile access but only 12th in data centers, a gap industry associations including Neo and the Brazilian Internet Steering Committee are pressing the government to close before the regional capital flow concentrates further south.

The Regional Substitution Pressure

Paraguay is not the only southern-cone competitor positioning to absorb capital that might otherwise have flowed to Brazil. Argentina’s Milei government is courting the same investor pool with a 20 billion-dollar US Treasury currency-stabilization package, a pending bilateral trade deal, and proposals to host Latin America’s first Stargate-anchored AI data center. Bolivia’s lithium triangle and Uruguay’s data-cable connectivity round out an emerging southern axis that, taken together, holds the renewable energy, the tax stability, and the political alignment with Washington that Brazil now strains to match.

What Could Derail the Paraguayan Thesis

Grid Resilience

On March 11, 2026, a single detached conductor at the Yguazu substation triggered a cascading failure that knocked out power to 90% of the country for nearly three hours, exposing the absence of a backup high-voltage corridor of equivalent capacity from Itaipu. Rio Times analysis at the time noted that Paraguay’s grid has no backup, a structural vulnerability hyperscale AI workloads cannot tolerate. The planned Yguazu-Valenzuela 500-kilovolt redundancy line is not yet complete.

The Demographic Math

Paraguay’s domestic electricity demand has been growing roughly 8% per year, and at that rate the surplus available for export or industrial offtakers could disappear within five years. Industry Minister Riquelme has acknowledged the 5-gigawatt ceiling publicly. The country needs new generation capacity, transmission redundancy, and offtake contracts to mature in parallel rather than sequentially, a coordination problem that has tripped up larger economies attempting industrial pivots.

The Political Risk

The Annex C renegotiation is unfinished and the 2024 Brazilian espionage episode that Lula publicly admitted, but attributed to the Bolsonaro administration, has chilled negotiating tempo. President Santiago Pena is contending with domestic political crises that could delay technical work. The earlier 19.28 dollar per kilowatt-month bridge agreement runs through end-2026; if no Annex C deal is signed before then, the legal framework for cross-border energy commerce enters uncertain ground.

The Sovereignty Exposure

The Rubio framing makes Paraguay explicitly a piece of the US AI supply chain, and Pena’s government has aligned with that vision. The Trump administration’s appetite for using Latin American energy and minerals to power US compute creates real foreign investment, but it also creates exposure to the kind of geopolitical pressure Rio Times has tracked across the hemisphere from Mexico to Ecuador. A future Democratic administration, or a souring of US-Paraguay political alignment, could reset the terms quickly.

What to Watch

• Itaipu Annex C signature: Brazilian Itaipu director Enio Verri targeted December 2026 for a finalized tariff and operating agreement; slippage past that date pushes the 2027 transition into legal uncertainty
• X8 Cloud Phase I commissioning: first 6-megawatt operation due 2026; site location, ANDE tariff structure and final Department of Commerce sign-off remain open
• Brazilian REDATA take-up: first hyperscale projects qualifying under the 5.2 billion reais program from January 1, 2026 will test whether Lula’s self-generation rule deters or channels investment
• Grid backup investment: ANDE’s Yguazu-Valenzuela 500-kilovolt redundancy line completion is the single most important infrastructure milestone for AI workload viability
• 2027 Itaipu base tariff: a 9 dollar per kilowatt-month outcome favors Brazilian industry; 12 to 15 dollar favors Paraguay’s investment thesis
