Brazil has developers. We don't need to copy anyone.
On the shores of a city once defined by Olympic ambition, Rio de Janeiro has placed a half-billion-dollar wager on becoming a nerve center of the artificial intelligence age, announcing a vast data campus where the Olympic Park once hosted the world's athletes. The investment by American firm Elea reflects a global scramble for the physical foundations of AI — electricity, water, connectivity, and human talent — resources Rio's leaders argue the city possesses in rare combination. Yet even as the infrastructure takes shape, Brazil's broader struggle to author its own rules for artificial intelligence reveals a familiar tension: the machinery of the future being built faster than the wisdom to govern it.
- The global race for AI computing infrastructure has become so urgent that cities are now competing the way ports once competed for shipping routes — and Rio is positioning itself as South America's essential node.
- A $550 million data center campus announced at Web Summit Rio promises 3.2 gigawatts of capacity by 2032, but the announcement lands against a backdrop of unresolved questions about who will truly benefit from this infrastructure.
- Brazil's proposed AI law, the Marco Legal da IA, is drawing sharp criticism from leading tech voices who say it blindly copies an already-outdated European framework, bypassing the public scrutiny that made Brazil's earlier internet governance a global model.
- Experts are urging Brazil to pursue open-source AI development as a path to technological sovereignty, warning that building data centers without building independent AI capacity risks making the country a permanent consumer of foreign systems.
- Web Summit Rio's 20% annual growth and 40,000 attendees from over 100 countries signal that international attention — including rising Chinese interest — is converging on the city, raising the stakes of getting both the infrastructure and the governance right.
At Web Summit Rio, South America's largest technology conference, Mayor Eduardo Cavaliere announced a $550 million investment from American firm Elea to build Rio AI City — a data center campus anchored in the Olympic Park, designed to reach 3.2 gigawatts of capacity by 2032. The announcement was a declaration of intent: Rio wants to be a critical node in the global AI infrastructure race.
The city's argument rests on geography and preparation. Its Atlantic coastline connects to submarine cable networks linking it to global internet infrastructure. It has abundant water, essential for cooling data centers. And the municipal government has been building a talent pipeline — robotics and coding programs now run in 312 schools, with the mayor stressing that students need not only mathematics but the language skills to communicate effectively with AI systems.
Web Summit founder Paddy Cosgrove drew a parallel between Rio and Lisbon, two cities hosting his global conferences that serve as regional gateways — Lisbon to Europe, Rio to Latin America. The Rio event has grown roughly 20% annually since its launch four years ago, with this year drawing around 40,000 participants from more than 100 countries. Cosgrove noted growing Chinese corporate interest in the region, a sign that Rio's ambitions are registering on the world stage.
But the day's conversations also exposed a deeper tension. On the same stage, OpenAI's Bruno Lewicki and technology lawyer Ronaldo Lemos debated Brazil's proposed AI law, the Marco Legal da IA. Lemos was pointed in his criticism: Brazil had once authored the Marco Civil da Internet, a landmark internet governance law that other nations studied and adapted. Now, he argued, the country was simply importing a European AI regulation that Europe itself had already revised — and doing so without adequate public deliberation.
Lemos pushed for a different path: open-source AI development that could build genuine technological sovereignty, reducing Brazil's dependence on foreign platforms. The legislative process, both men agreed, was moving without sufficient transparency or public input.
What Rio's announcement ultimately reveals is a city constructing the physical and educational foundations of an AI future, while the country around it has yet to settle the rules that will determine who shapes that future — and who it serves.
Rio de Janeiro is betting half a billion dollars that it can become a critical node in the global race for artificial intelligence infrastructure. On the stage of Web Summit Rio, the city's mayor Eduardo Cavaliere announced a $550 million investment from American firm Elea to build the first phase of Rio AI City—a sprawling campus of data centers anchored in the Olympic Park with the capacity to eventually generate 3.2 gigawatts of power by 2032. The announcement came at South America's largest technology conference, where thousands of investors, entrepreneurs, and technologists had gathered to discuss the future of the digital economy.
The timing reflects something urgent happening in global tech: the scramble for computing infrastructure. Data centers consume enormous amounts of electricity and cooling water, and they need to be located where those resources exist in abundance and where talent can be found. Rio is making a calculated argument that it has all three. The city sits on the Atlantic coast with access to submarine cable networks that connect it directly to global internet infrastructure. It has water. And the municipal government is investing heavily in STEM education—robotics and coding programs now run in 312 schools across the city, starting in the earliest grades. The mayor emphasized that students need more than mathematics; they need language skills to write effective AI prompts. The city's basic education index grew by 12 percent in early grades, according to 2024 data.
Paddy Cosgrove, the founder of Web Summit, drew a parallel between Rio and Lisbon, another city hosting one of his five global technology conferences. Both, he suggested, offer quality of life that allows them to retain and attract talent. Both serve as gateways to their regions—Lisbon to Europe, Rio to Latin America. The Rio event itself has grown roughly 20 percent annually since its launch four years ago. This year, organizers expected around 40,000 participants from more than 100 countries to pass through the conference. Cosgrove noted rising interest from Chinese companies in the region, a sign that Rio's positioning as a Latin American tech hub is registering internationally.
Yet the announcement of private investment in data center capacity sits uneasily alongside a broader debate about how Brazil will govern artificial intelligence itself. On the same day, two prominent voices in Brazilian tech policy—Bruno Lewicki, head of public policy at OpenAI, and Ronaldo Lemos, a technology lawyer—took the main stage to discuss the country's AI regulatory framework. Lewicki highlighted a partnership between OpenAI and Brazil's electoral authority to develop tools for detecting AI-generated images, a practical step toward election integrity. But both men expressed frustration with the legislative process surrounding Brazil's proposed AI law, known as the Marco Legal da Inteligência Artificial, or PL 2338/2023.
Lemos was blunt in his criticism. Brazil, he pointed out, had authored the Marco Civil da Internet, a landmark internet governance law that other countries studied and adapted. Yet now the country was simply copying a European AI regulation from 2019—one that Europe itself had already substantially revised. The approach felt backward. Lemos argued that Brazil should be developing its own regulatory approach, one that could reduce dependence on companies like OpenAI and instead nurture the country's own developer community. He suggested that open-source AI models offered a path forward, a way for Brazil to build technological sovereignty rather than remain a consumer of foreign systems. The legislative process, he and Lewicki both stressed, was happening without sufficient public scrutiny or input.
What emerges from Rio's announcement is a city making a physical and educational bet on its future in AI, while the country around it struggles to establish the legal and policy framework that will govern how that technology is developed and deployed. The data centers will be built. The talent pipeline is being constructed. But the rules of the game remain unsettled, and that uncertainty hangs over everything.

The Hearth Conversation Another angle on the story
Why does Rio think it can compete with places like Virginia or Singapore for data center investment?
Water, cables, and people. The city has Atlantic access for submarine cables, abundant freshwater for cooling, and a government that's actually building a pipeline of engineers from elementary school onward. It's not just about existing infrastructure—it's about showing investors a long-term commitment to the talent side.
But doesn't every city claim to have good talent?
True, but Rio is quantifying it. Three hundred twelve schools with robotics and coding programs. A 12 percent jump in basic education metrics. That's not rhetoric—that's a measurable bet that in ten years, there will be people here who can actually do the work.
The mayor mentioned learning Portuguese for prompts. That's an odd detail.
It's not odd at all. He's saying that AI work isn't just mathematics anymore. You need language fluency to write good instructions to these systems. It's a signal that Rio understands the job has changed.
What about the regulatory stuff? Lemos seemed pretty angry.
He was. Brazil wrote the book on internet governance once. Now it's copying a European law that Europe has already moved past. The frustration is that the country has the talent to write its own rules, but instead it's letting the process happen in the dark.
Does that kill the data center investment?
Not immediately. Private money doesn't wait for perfect regulation. But it does mean Brazil might end up with world-class infrastructure governed by rules it didn't write for itself. That's a different kind of dependence.
So Rio is building the hardware while the country fumbles the software?
Exactly. And that gap is where the real risk lives.
