US prediction market operator Kalshi has executed its first international expansion, launching in Brazil through a partnership with local brokerage XP International. The move puts Kalshi ahead of B3, Brazil’s stock exchange operator, which secured regulatory approval in February but has yet to bring its competing platform to market.

Clients of XP’s Clear Corretora brand with international investment accounts can now access Kalshi’s platform to trade contracts on real-world events. The initial Brazilian offering focuses on financial and economic outcomes, a narrower scope than Kalshi’s US markets, which extend to sports and entertainment.

Strategic Timing and Market Entry

The announcement represents a significant first-mover advantage in a market with considerable growth potential. Brazil’s B3 received regulatory clearance from the country’s Securities and Exchange Commission to operate prediction markets two months ago, with industry sources indicating a planned March launch.

Kalshi’s early entry establishes immediate brand presence and market share before the local incumbent arrives.

Kalshi co-founder Luana Lopes Lara, a Brazilian national, telegraphed the expansion in December 2024, projecting an early 2026 announcement. The accelerated timeline suggests operational urgency, likely driven by competitive intelligence regarding B3’s progress.

Regulatory Ambiguity Creates Opportunity

Brazil’s prediction market sector operates in what legal practitioners describe as a regulatory vacuum. Worth knowing: while the country’s online betting industry came under formal oversight on 1 January 2024, those regulations apply exclusively to licensed fixed-odds operators. They impose substantial requirements including mandatory Brazilian headquarters, rigorous KYC standards, certification protocols, a BRL 30 million ($5.8 million) licensing fee, and considerable tax obligations.

Prediction markets fall outside this framework entirely.

Andre Santa Ritta, partner at Pinheiro Neto Advogados, characterised the situation as a “regulatory grey zone” that creates both opportunity and uncertainty. Unlike the United States, where prediction markets operate under derivatives regulation, Brazil has yet to classify or govern the sector.

This ambiguity presents a double-edged commercial proposition. Operators willing to accept regulatory risk can enter the market with minimal barriers, establishing operations before formal rules materialise. However, the lack of clarity also raises consumer protection concerns and potential competitive distortions between regulated betting operators and unregulated prediction market platforms.

Market Implications

The partnership with XP International, one of Brazil’s largest financial institutions, provides Kalshi with immediate credibility and distribution infrastructure. By integrating with an established brokerage platform rather than launching a standalone operation, Kalshi gains access to XP’s existing client base and compliance frameworks, potentially mitigating some regulatory exposure.

The success of this model could influence how other international operators approach Latin American expansion, particularly in markets where prediction markets occupy similar regulatory grey zones. Brazil’s evolving stance on these platforms will likely set precedents across the region.

Whether Brazil’s authorities move to clarify the regulatory status of prediction markets, and how quickly they do so, will determine whether Kalshi’s early entry proves strategically prescient or simply opportunistic. For now, the company has secured a meaningful head start in South America’s largest economy.
