- Kalshi: 79.5%.
- Difference: 0.7 percentage points.
Luiz Inácio Lula da Silva
- Polymarket: 20.5%.
- Kalshi: 20.5%.
- Difference: 0 percentage points.

The percentages are neither official election results nor traditional voter intention polling figures.
Why Do Prices Differ Between Platforms?
Although Polymarket and Kalshi offer contracts linked to the same event, their prices can differ because each platform operates a separate marketplace.
The main factors include:
- Different participants and liquidity conditions.
- Trading fees and transaction costs.
- Variations in contract supply and demand.
- Specific settlement requirements.
- Regulatory and geographical access restrictions.
For Bolsonaro, the affirmative contract is priced lower on Polymarket, while Lula’s corresponding contract carries the same quoted value on both exchanges.
Small price differences do not necessarily create arbitrage opportunities, as transaction costs and settlement rules must also be considered.
Brazil and the Development of Prediction Markets
Brazil’s presidential election is among the international political events attracting activity across prediction market platforms.
These services allow participants to trade contracts linked to future outcomes, including elections, economic indicators and sporting competitions.
However, Polymarket maintains geographical access restrictions affecting users located in Brazil, which should be distinguished from the public availability of market price information.
The activity illustrates growing interest in using traded contract prices to examine the expectations expressed by market participants.
Next Steps and Impact
Brazil’s presidential runoff is scheduled for 25 October 2026.
Until then, contract prices may continue to change in response to trading activity and newly available information.
The Polymarket–Kalshi comparison is refreshed twice daily, providing updated information on pricing differences between the two exchanges.
For the prediction markets industry, Brazil’s electoral process provides a case study in liquidity, price formation and competition between trading platforms.
