Brazil Annual Inflation 2026

According to the latest prediction market data for the query “Brazil Annual Inflation 2026”, traders have formed a strong consensus.

Currently, 5.00-5.49% is dominating the market with an overwhelming 32.2% chance of winning. 6.00-6.49% follows in second place at 20%, while 5.50-5.99% sits in third with 19.9%. The betting volume for this specific market has already reached $65.5K, reflecting intense industry interest.

To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• 5.00-5.49% (32.2%): Currently commanding the highest probability, 5.00-5.49% is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 32¢, signaling a high degree of market conviction. This contract alone has generated $7.1K in volume.

🥈 Tier 2: The Primary Challengers

• 6.00-6.49% (20%): Positioned as the most viable alternative, 6.00-6.49% maintains a 20% chance of resolving true. Its “Buy Yes” shares currently trade at 20¢.
• 5.50-5.99% (19.9%): Sitting in third place with a 19.9% probability, the market shows measured skepticism toward 5.50-5.99%, treating it as an outside wildcard unless momentum shifts.

🥉 Tier 3: The Long-Tail Options (Combining for ~28%)

Beyond the top three choices, a wide field of macro variables and long-shot outcomes are being tracked. While their individual probabilities hover low, they represent crucial hedges for speculative traders:

• Alternative Options: This includes 4.50-4.99% (11.2%), 4.00-4.49% (5.7%), and 7.00%+ (4.4%).
• Speculative Volume: Despite low statistical likelihood, certain long-tail contracts like 6.50-6.99% are still attracting notable interest.

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

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome 5.50-5.99% currently trades at 19.9%, but our AI places its Fair Value at just 3.1%. This creates a large negative EV Gap of -16.8%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies 3.50-3.99% as the premium value opportunity on the board. While the market only assigns it a 3.1% trading probability, our AI’s Fair Value assessment sits at 18.9% — yielding an impressive +15.9% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include 3.00-3.49% (EV Gap: +7.1%) and 4.50-4.99% (EV Gap: +6.1%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
