Price history
27¢ current
+22¢Contract brief
This is a market about the variation of consumer prices in Brazil over the 12-month period ending December 2026, as reported by the Brazilian Institute of Geography and Statistics (IBGE). This market will resolve according to the percentage change in the Extended National Consumer Price Index (IPCA) during the 12-month period ending December 2026 according to the monthly IBGE report. The resolution source for this market will be the IBGE Extended National Consumer Price Index monthly report released for December 2026, currently scheduled to be released on January 12, 2027. Resolution of this market will take place upon release of the aforementioned data. If no data for the specified month is released by the date the next month's data is scheduled to be released, this market will resolve based on data from the last available month. You can find the relevant figure by locating the report for December 2026 on the Press Releases page (https://agenciadenoticias.ibge.gov.br/en/agencia-press-room.html), locating the Period-Rate table and finding the IPCA growth rate figure in the column labeled "Rate" and the Row labeled “Cumulative in the year / 12 Months”. Changes in the IBGE’s reporting format will not disqualify a published relevant figure from counting. Note: the resolution source for this market will be the official monthly IBGE IPCA news release which reports inflation during 12-month periods to two decimal points (e.g. 4.26%). Thus, this is the level of precision that will be used when resolving the market. For the full release schedule, see: https://www.ibge.gov.br/en/calendar.html

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
