PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Polymarket includes a large number of 'Person X' candidates, while Kalshi focuses on a defined set of named candidates, creating a scope divergence.Hero tip: Be mindful of the broader candidate pool on Polymarket. A less-known candidate winning could trigger resolution on Polymarket, while Kalshi focuses on the more prominent contenders.

Critical divergence points:

  • Polymarket: Polymarket markets cover a wide range of potential candidates, including generic 'Person X' options. Resolution is based on the candidate listed as the winner by a consensus of credible reporting or the official TSE results, with a fallback to 'Other' if no winner is determined by June 30, 2027. "This market includes any potential second round. If the result of this election isn't known by June 30, 2027, 11:59 PM ET, the market will resolve to "Other".
  • Kalshi: Kalshi markets are specific to named candidates. Resolution occurs if the named candidate wins the election. "If Aldo Rebelo has won the 2026 Brazilian presidential election, then the market resolves to Yes."
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Frequently asked questions

On Polymarket and Kalshi, this dashboard tracks the collective wisdom of traders predicting the outcome of the Brazil presidential election. Currently, the Polymarket and Kalshi markets show a consensus view, with a combined volume of $221,402,774 and 24-hour volume of $3,999,857. The dashboard aggregates data from both platforms to provide a comprehensive overview of the probabilities assigned to different potential winners. This allows for a broader understanding of expectations than looking at any single market in isolation. The current view of the Brazil presidential election market reflects a dynamic assessment of evolving information.

Prediction market odds, like those found in this market, often offer a different perspective than traditional polling averages. While polls capture stated preferences, this market reflects what people are willing to *stake* on those preferences. This can lead to divergences, as prediction markets incorporate not only who is currently favored but also assessments of uncertainty and the likelihood of unexpected events. Polling averages can be susceptible to biases in sampling or question wording, whereas the financial incentive in this market encourages more honest and informed predictions. It's important to consider both sources of information when forming an overall view.

Prices on Polymarket and Kalshi can diverge for several reasons. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform has its own user base, trading dynamics, and fee structures, all of which can influence price discovery. Differences in liquidity – the amount of volume traded – can also contribute to price discrepancies. Furthermore, differing interpretations of available information or varying levels of risk aversion among traders on each platform can lead to differing probabilities. Currently, Polymarket currently favors Will Flávio Bolsonaro win the 2026 Brazilian presidential election? at 80.0%, while Kalshi leans toward Will Flávio Bolsonaro win the 2026 Brazilian presidential election? at 81.0%.

This market resolves around Nov 25, 2027, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will be based on the official results declared by the relevant electoral authorities in Brazil. The outcome will reflect the candidate who receives the most votes in the presidential election. The process ensures a transparent and objective determination of the winner, aligned with established democratic procedures and widely accepted sources of truth. Traders should monitor official announcements as the election progresses to stay informed about the potential resolution timeline.

Numerous signals and events could significantly impact this market. Major developments in the Brazilian economy, such as shifts in inflation or unemployment rates, could influence voter sentiment. Significant political endorsements or scandals involving leading candidates would also likely cause price movements. Unexpected policy announcements or changes in campaign strategy could also shift probabilities. Furthermore, external factors like international relations or global economic trends could play a role. Any event that alters perceptions of the candidates’ chances of winning has the potential to move this market.
