Rafael Brunati and Celso Basílio, lawyers at Silveiro Advogados specializing in regulated markets, corporate law, and competition law, analyze the recent measures adopted by Brazil’s National Monetary Council (CMN) and the Secretariat of Prizes and Betting (SPA/MF) and their impact on the iGaming and sports betting industry.

In this article, they examine how the new regulatory framework reshapes the boundaries between betting, financial instruments, and emerging digital market models, while reinforcing Law No. 14,790/2023 as the central pillar of regulation in the sector.

The set of measures recently adopted by the National Monetary Council (CMN) and the Secretariat of Prizes and Betting of the Ministry of Finance (SPA/MF) marks a new chapter in the regulatory consolidation of Brazil’s iGaming and sports betting market.

More than a targeted response to so-called predictive markets, these initiatives signal a broader effort to redefine the boundaries between authorized betting activities, financial instruments, and operations considered irregular in the country.

CMN Resolution No. 5,298/2026 prohibited the offering and trading of derivatives linked to betting, sports events, online games, and political, electoral, cultural, or entertainment themes without a financial-economic reference.

In the same direction, SPA/MF Technical Note No. 2,958/2026 classified predictive market platforms as illegal fixed-odds betting operations, leading to the blocking of dozens of platforms by Anatel.

The move clearly reinforces Law No. 14,790/2023 as the exclusive regulatory framework for fixed-odds betting in Brazil.

In practice, the government has begun to draw a sharper line around who can operate in this market and under what conditions.

Platforms that previously positioned themselves as financial markets, event-based contracts, or alternative technological structures are now being materially treated as betting operators.

The regulatory message is direct: if a product targets the same audience, uses similar economic logic to betting, and involves risk linked to future events, it is likely to fall within the SPA’s regulatory perimeter.

From a competitive and regulatory standpoint, this produces a meaningful effect for licensed operators. Companies that have invested in licensing, compliance, anti-money laundering controls, sports integrity, responsible gaming policies, and regulatory infrastructure are no longer competing with platforms operating outside these requirements under alternative legal interpretations.

This indirectly strengthens the economic value of the license granted by the SPA.

At the same time, this strengthening comes with a significant increase in operational and compliance obligations.

The recent measures also reopen an important discussion on the regulatory limits of so-called betting exchanges and peer-to-peer models.

SPA/MF Technical Note No. 2,958/2026 itself acknowledges that betting between users and the existence of dynamic pricing do not necessarily alter the nature of fixed-odds betting.

This interpretation is relevant because it brings predictive markets closer to exchange-style betting structures already contemplated under Law No. 14,790/2023.

This point could, in the future, open space for regulated betting exchange models in Brazil, provided they fall within the SPA’s authorized perimeter. However, operational rules for such formats have not yet been defined by the regulator, leaving a significant area of uncertainty for operators seeking product innovation.

From another perspective, these measures are also likely to generate substantial litigation.

There are important debates regarding the limits of the CMN’s authority to restrict certain types of derivatives, the SPA’s interpretative role regarding predictive markets, and even the blocking of platforms without judicial orders.

Regardless of the outcome of these disputes, the fact is that Brazil’s iGaming and sports betting market is entering a new phase.

Regulatory logic is no longer focused solely on formal authorization to operate, but increasingly incorporates issues such as financial integrity, protection of vulnerable users, data governance, payment traceability, and continuous operational supervision.

The sector continues to grow, but now within a significantly more sophisticated—and more demanding—environment. For licensed operators, this simultaneously creates a barrier to entry for unregulated competitors and increases compliance costs.

In an increasingly regulated market, competitive advantage is likely to depend less on the ability to offer bets and more on the capacity to operate with regulatory security, operational integrity, and rapid adaptation to new state requirements.
