Polymarket Returns to Brazilian Government Scrutiny Over Election Markets
Brazil.- 24 September 2026 | www.zonadeazar.com Polymarket has returned to the attention of Brazilian authorities over the offering and promotion of markets linked to the country’s 2026 presidential election.
Brazil‘s Attorney General’s Office, AGU, has requested technical and legal information from the Ministry of Finance as it considers whether additional action may be required.
TSE Involvement
Brazil‘s Superior Electoral Court, TSE, received complaints concerning markets tied to the presidential election.
The matter was subsequently referred to the AGU.
Request to the SPA
The AGU has asked the Secretariat of Prizes and Betting, SPA, for information on the regulatory measures already taken against Polymarket and possible additional enforcement options.
The review includes:
- Supervisory procedures.
- Potential sanctions.
- Administrative notifications.
- Suspensions.
- Blocking measures.
- Action involving partners or intermediaries.
Markets on the October Election
Polymarket continues to list contracts from outside Brazil relating to the outcome of the country’s presidential election.
These products allow users to take financial positions on different political outcomes.
Such contracts are not authorised under Brazil‘s current framework.
Polymarket Remains Blocked
The Ministry of Finance reiterated that Polymarket remains officially blocked in Brazil.
The restrictions also cover digital channels linked to the platform where included in existing enforcement measures.
Access Does Not Mean Authorisation
Authorities stressed that the fact some users may still be able to reach certain addresses does not mean Polymarket is authorised to operate.
Technical implementation can occur at different times across individual telecommunications providers.
Role of Anatel
The original blocking instruction was issued by the SPA and communicated to telecommunications regulator Anatel.
The agency distributes instructions to providers responsible for implementing access restrictions.
Broad Provider Network
The blocking system involves thousands of telecommunications providers across Brazil.
Differences in implementation times can mean an address temporarily remains accessible on some networks.
VPN Access
There have also been reports of users accessing the platform through virtual private networks, VPNs.
Such technology can mask or alter a user’s apparent geographic location.
Using a VPN, however, does not change the platform’s legal status in Brazil.
Deposits and Betting Restrictions
The Ministry of Finance has said that even where a webpage can technically still be opened, enforcement measures are intended to prevent effective betting activity.
The SPA continues monitoring attempts to circumvent those restrictions.
Ongoing Monitoring
The Secretariat continually reviews the effectiveness of measures against unauthorised operators.
Additional steps can be taken when new domains, access mechanisms or alternative structures emerge.
April Regulatory Action
The current framework was significantly strengthened in April 2026.
The SPA issued a technical note specifically addressing the irregular operation of fixed-odds betting through so-called prediction markets.
Technical Note 2,958/2026
SPA/MF Technical Note No. 2,958 of 23 April 2026 examined the structure of prediction-market platforms and their compatibility with Brazilian law.
The Secretariat concluded that certain products could amount to unauthorised betting when linked to non-financial events.
National Monetary Council
At the same time, the National Monetary Council tightened rules governing event contracts.
The framework limits qualifying financial contracts to economic or financial reference events.
Politics and Elections Excluded
The changes exclude contracts linked to areas such as:
- Elections.
- Politics.
- Sport.
- Entertainment.
- Culture.
- Reality television.
- Other non-financial events.
Prediction-Market Blocking
Following those decisions, Anatel began blocking a range of prediction-market platforms.
Polymarket was among those affected.
Around 27 Platforms
Brazilian authorities included Polymarket within a group of roughly 27 platforms targeted by blocking measures in April.
The aim was to prevent products considered incompatible with the country’s financial and betting rules.
Financial Contract or Bet
A central regulatory issue is the legal nature of the contracts.
Prediction-market platforms frequently structure their products as contracts linked to the outcome of future events.
Brazil has determined that where no legitimate economic or financial reference exists, financial-market rules cannot be used to offer products equivalent to betting.
Regulated Fixed-Odds Market
Brazil has operated a federal fixed-odds betting regime since 2025.
Operators must be authorised by the SPA to participate in the regulated market.
No SPA Authorisation
Polymarket does not hold a federal SPA betting authorisation in Brazil.
It is therefore not part of the authorised operator market.
Portuguese-Language Social Media
Polymarket’s digital activity has also attracted attention.
The company maintains Portuguese-language content and posts concerning Brazilian and international politics.
This has contributed to debate over whether a technically blocked platform continues directing promotional content towards Brazilian users.
Electoral Sensitivity
Election-related contracts add an additional institutional dimension.
The involvement of the TSE means the issue now extends beyond financial and gambling regulation into the electoral environment.
Not Opinion Polls
Polymarket prices should not be treated as voter-intention polling.
They are prices generated by buyers and sellers within a market.
They can change according to:
- Liquidity.
- Trading volume.
- Open positions.
- Available information.
- Participant behaviour.
They therefore do not represent a statistical measurement of the electorate.
New Tools Against Illegal Betting
Brazil recently strengthened its enforcement toolkit against unauthorised gambling operators.
SPA/MF Ordinance No. 2,750/2026 expanded mechanisms for identifying and disrupting payment flows linked to irregular fixed-odds betting.
Financial Blocking
The framework strengthens action involving:
- Accounts.
- Payment instruments.
- Receipt of funds.
- Transfers.
- New transactions.
This extends enforcement beyond domain blocking alone.
Inter-Agency Cooperation
The Polymarket case now involves several Brazilian authorities.
These include:
- AGU.
- TSE.
- SPA.
- Ministry of Finance.
- Anatel.
Their involvement reflects the cross-sector nature of the prediction-market debate.
Industry Context
Prediction markets are generating regulatory debate across multiple jurisdictions.
The central question is when a contract should be regarded as a financial instrument and when it functions in practice as a wager on an event.
Brazil has adopted a restrictive approach towards contracts linked to politics, sport and entertainment.
Next Steps and Impact
The AGU will assess the information supplied by the SPA before determining whether further measures are necessary.
The review will focus on whether existing mechanisms are sufficient to prevent the offering and promotion of election-related markets to Brazilian users.
For now, Polymarket remains outside the authorised market and the blocking measures introduced in April remain in force.
