Brazil’s Exchange Courts Small Savers as Lula Targets Betting Apps

Brazil’s exchange wants to sell small savers a contract on the next inflation print. Its government wants to shut the apps those savers currently use.

B3 is evaluating taking its event contracts to retail investors, Finsiders Brasil reported from a panel on 15 September, investors. Two days later, Estadão reported that the finance ministry had drafted a measure to ban online casino apps.

What B3 Has Already Built

B3 is Brazil’s only stock and derivatives exchange, based in São Paulo. A forerunner product on rate decisions dates from 2020.

The event-contract line itself began on 27 April 2026, when six contracts started trading. Those six reference the Ibovespa index, the United States dollar and bitcoin.

Contracts on the IPCA inflation index and on quarterly GDP followed. Luiz Masagão is B3’s vice-president for products and customers; he said the launch followed the evolution of prediction markets abroad.

Masagão said the contracts deliver a simplified experience for investors. He added that they keep the safety parameters of B3’s regulated environment.

The exchange publishes the product list on its own website. Twelve contracts across seven underlyings are listed there now, including ether and solana.

How an Event Contract Works

Each contract asks one question with a yes or no answer. An example is whether the dollar closes above a set level that day.

Prices move between R$0 and R$100, so the ceiling is about US$19.41. A holder who is right receives R$100 and a holder who is wrong receives nothing.

The price therefore reads as a probability. A contract at R$70 implies a seventy per cent chance in the market’s view.

Jerson Zanlorenzi, a partner at BTG Pactual, made that point at the B3 Week event. He said a contract at 70 cents in a hundred shows the probability directly.

Zanlorenzi called it a lower-risk entry point for people new to futures. He said the gain and the loss are both known in advance.

That differs from a futures contract, which needs margin and daily settlement. The event contract simply pays a fixed sum or nothing.

The Rule That Draws the Line

Brazil’s National Monetary Council issued Resolution 5,298 on 24 April 2026. It took effect on 4 May.

The rule bans derivatives referenced to sporting, political, electoral, cultural or entertainment events. It allows those tied to economic and financial variables.

Permitted references include interest rates, exchange rates, price indices, commodities and listed securities. The CVM may bar further underlyings at its discretion.

The ban also reaches offers made into Brazil from abroad. Law firm Machado Meyer read it as covering indirect access arrangements.

That wording pushed Polymarket and Kalshi outside the Brazilian perimeter. It left B3’s economic contracts inside it.

The CVM has separately limited these products to professional investors. That means R$10 million in financial assets, about US$1.9 million, or a regulator’s certification.

Why B3 Now Wants the Retail Investor

The pitch was made at B3 Week 2026 in São Paulo on 15 September. Finsiders Brasil reported the panel the next day.

Estadão, reporting the panel on 16 September, headlined its account on how the exchange hopes to avoid an efeito bet. The phrase is the newspaper’s own.

Silvia Bugelli, then B3’s legal director, had put the commercial case in March. She said that without a broad market there is no liquidity.

Bugelli added that without liquidity a contract does not form a price. That is the exchange’s core argument for widening access.

Daniel Maeda, B3’s superintendent for legal affairs, spoke at Rio Innovation Week on 4 August. He said B3 had discussed the target audience with the CVM.

João Accioly, a CVM director, said removing the audience barrier is the watershed for this market. He also said the bureaucrat needs educating alongside the investor.

B3’s Own Words on Bets

B3 runs an education portal called Bora Investir. It published an explainer on prediction markets and bets in December 2025.

The portal says that in prediction markets people bet against other people, not against the house. That is the exchange’s own framing of the difference.

It adds that a betting firm sets the odds itself and profits when bettors lose. Prediction market operators instead earn fees per transaction.

The portal also notes that a position can be traded before the event settles. A sports bet cannot be resold in the same way.

Thiago Godoy, who runs the Papai Financeiro education project, sounded a warning on the same panel. He described users trading hundreds and then thousands of times in short periods.

Godoy said technology can track how often someone trades and how much they stake. He argued that such monitoring should come with retail access.

The Measure Against Betting Apps

Estadão reported on 17 September that the finance ministry had drafted a provisional measure. It said the text was under review at the Planalto palace.

The report said publication was expected within days, before the first round of the October election. A provisional measure takes effect on publication and then needs congressional approval.

The draft targets online casino games rather than sports betting. Estadão reported that sports wagers and club sponsorship would stay outside it if the current design holds.

The government is studying a clause delaying the ban by 180 days. That would force Congress to vote before any prohibition started.

President Lula said on 14 September that betting is a disease and not a game. He said the government would announce a drastic decision soon.

Estadão said the finance ministry and the Casa Civil did not comment. Nothing has been published in the official gazette as of 18 September.

What a Ban Would Cost the State

Industry figures cited by Estadão put online casino games at about 80 per cent of operator revenue. A ban would therefore hit most of the sector’s income.

Each licensed company paid R$30 million, about US$5.8 million, for a five-year authorisation. Estadão reported that the state would have to refund part of that money.

Brazil’s fiscal responsibility law also requires compensation for forgone revenue. That is a second budget problem for the same measure.

The Receita Federal collected R$8.747 billion from gaming and betting between January and July 2026. That is about US$1.7 billion, and roughly 77 per cent more than a year earlier.

The levy on gross gaming revenue was 12 per cent until March and 13 per cent from April. A separate 15 per cent income tax applies to bettors’ net prizes.

Bettors deposited R$88.4 billion, about US$17.2 billion, in licensed sites in the first half of 2026. Estadão counted 31,821,805 unique bettors across almost 119 million accounts.

Football’s Sponsorship Problem

Eight clubs signed a joint manifesto against a ban on 17 September, and a dozen more published the text. Flamengo, Vasco, Fluminense, Botafogo, São Paulo, Santos, Palmeiras and Cruzeiro signed it.

The São Paulo and Rio de Janeiro state federations signed as well. Lance reported that betting firms pay Série A clubs more than R$1 billion a year.

That is about US$194 million at current rates. Reported individual deals run from around R$100 million a year at Palmeiras to far more at Flamengo.

The manifesto argued that the money also reaches smaller clubs and lower divisions. It said no other sector could immediately replace that investment in the interior.

The sector’s own estimate of the loss to football is around R$1 billion. Those figures come from clubs and industry bodies, not from an audited filing.

Betting associations have warned that demand would move to unlicensed sites. The sector estimates the illegal market already matches the legal one in size.

What the Household Data Shows

Brazil’s central bank published a technical study on the betting market in September 2024. It used Pix instant payment receipts from betting companies as its base.

That study found monthly transfers of R$18 billion to R$21 billion, roughly US$3.5 billion to US$4.1 billion. It counted about 24 million individuals sending at least one payment.

The CNC, Brazil’s trade confederation, put monthly spending at R$30 billion for March 2026. That is about US$5.8 billion, drawn from its own consumer debt survey.

The CNC used a difference-in-differences method comparing the periods before and after regulation. Its chief economist, Fabio Bentes, linked the outflow to weaker retail sales.

A study by the Made centre at the University of São Paulo landed on 15 September. It estimated that betting cut economic activity by R$120 billion to R$141 billion in 2025.

That range equals about US$23.3 billion to US$27.4 billion, or 0.9 to 1.1 per cent of output. The finance ministry works with a smaller estimate of around R$60 billion, near US$11.6 billion, a year.

What It Means If You Invest or Live in Brazil

Retail investors cannot buy these contracts today. Access still depends on a CVM rule change that has no published timetable.

Anyone offering contracts on football matches or elections to Brazilian residents sits outside Resolution 5,298. That applies to offshore platforms marketing into the country.

B3 itself trades in São Paulo under the ticker B3SA3. Event contracts are a small line next to its equities and futures business.

Investors holding Brazilian media or football-linked assets face a different question. Sponsorship income would be exposed if the measure widened to sports betting.

Every dollar figure here uses R$5.1521 to the dollar. That is the Banco Central PTAX selling rate for 17 September 2026.

The real has moved little this month against the dollar. Readers converting older reais figures should check the rate for the date concerned.

What Is Not Yet Known

The text of the provisional measure has not been published. Everything about its scope comes from reporting, not from an official document.

It is not confirmed that sports betting and club sponsorship will be spared. Earlier reports described a broader prohibition under discussion.

The CVM has not opened a public consultation on retail access to event contracts. No B3 executive has given a launch date for a retail product.

The size of any licence refund is unclear. Some 188 brands appear on the regulator’s authorised list, though company counts differ by source.

Estimates of household betting outflows vary widely by method. Deposits, losses and gross gaming revenue are three different measures and are often conflated.

Whether Congress would approve a ban is untested. A provisional measure lapses if deputies and senators do not vote it through.
