# CPI year-over-year in Apr 2026? In Apr 2026 Updated: April 20, 2026 Category: Economics Tags: Inflation HTML: /markets/economics/inflation/cpi-year-over-year-in-apr-2026/ ## Short Answer **The model assigns meaningfully lower odds than the market for the CPI year-over-year in April 2026 being Exactly 3.6%.** The **model** sees potential mispricing for this outcome at **16.8%** versus the **market**'s **28.0%**, indicating a notable divergence in their **probability** assessments. ## Key Claims (January 2026) **- Leading rent indices predict near zero YoY growth by late 2025.** Significant shelter disinflation will pull overall CPI below **2.5%** by April 2026. Federal Reserve projects **2.2%** core PCE inflation by year-end 2025. Tightening labor supply may elevate costs, adding some upward CPI pressure. ### Why This Matters (GEO) - AI agents extract claims, not arguments. - Improves citation probability in summaries and answer cards. - Enables fact stitching across multiple sources. ## Executive Verdict **Key takeaway.** **Model** sees **1.4%** **probability** versus 1c **market** for >=**3.5%** CPI, which is strongly countered by disinflationary evidence. ### Who Wins and Why | Outcome | Market | Model | Why | | --- | --- | --- | --- | | Outcome | 1.0% | 1.4% | Model higher by 0.4pp | ## Model vs Market - Model Probability: 1.4% (Yes) - Market Probability: 1.0% (Yes) - Yes refers to: Yes - Edge: +0.4pp - Expected Return: +35.4% - R-Score: 0.04 - Total Volume: $408,343.77 - 24h Volume: $26,126.76 - Open Interest: $75,443.61 - Expiration: May 12, 2026 ## Market Behavior & Price Dynamics This market's price action is characterized by an initial drop followed by a prolonged period of stability. The price opened at its peak of 2.0% and subsequently fell to its all-time low of 1.0%, where it has remained. The overall trend after this initial decline has been sideways, trading in an extremely narrow range at the bottom of its historical price band. The most significant movement was this early drop from 2.0% to 1.0%. Given the absence of specific news or economic context provided, the direct cause for this initial, sharp decrease in perceived probability cannot be determined. Trading volume in this market is exceptionally low, with only 104 contracts traded across its history. This pattern of thin trading suggests a lack of market participation and conviction. Price movements in such a low-volume environment may not reflect a broad consensus and can be influenced by a small number of trades. The price points of 2.0% and 1.0% have acted as the clear resistance and support levels, respectively, defining the entire trading history of the contract. The price has been firmly established at the 1.0% support level for a significant period. The chart suggests that initial market sentiment, though weak at 2.0%, has soured considerably. The current price of 1.0% indicates that traders assign a very low probability to the year-over-year CPI meeting the contract's threshold in April 2026. However, the extremely light trading volume is a critical factor, implying that this pessimistic sentiment is not supported by significant market activity or capital. This could indicate either a lack of interest in the long-term forecast or a wait-and-see approach from most traders. ## Contract Snapshot This market resolves to YES if the Bureau of Labor Statistics reports the Consumer Price Index (CPI) year-over-year for April 2026 as exactly 3.6%; otherwise, it resolves to NO. The market opened on March 18, 2026, and will close either immediately after the outcome is verified or by May 12, 2026, at 8:29am EDT, with payouts projected 30 minutes after closing. The event outcomes are mutually exclusive. ## Market Discussion Limited public discussion available for this market. ## What Are the Federal Reserve's 2025 Economic Projections? Year-end 2025 Core PCE Inflation Projection | 2.2% (December 2024 SEP) [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm) | Year-end 2025 Federal Funds Rate Projection | 4.4% (December 2024 SEP) [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm) | Fed's Long-Run Inflation Target | 2 percent [[^]](https://www.federalreserve.gov/monetarypolicy/2024-07-mpr-part3.htm) | **The Federal Reserve projects year-end 2025 core inflation slightly above target** The Federal Reserve projects year-end 2025 core inflation slightly above target. The Federal Reserve's median projection for year-end 2025 core Personal Consumption Expenditures (PCE) inflation, as published in the December 2024 Summary of Economic Projections (SEP), is 2.2 percent [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm). This figure suggests that most Federal Open **Market** Committee (FOMC) participants expect core inflation to remain marginally above the Fed's 2 percent long-run target through the end of 2025 [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm). Achieving price stability, defined as a 2 percent inflation rate over the longer run, is a key component of the Fed's dual mandate [[^]](https://www.federalreserve.gov/monetarypolicy/2024-07-mpr-part3.htm). This inflation outlook guides the projected federal funds rate. The December 2024 SEP also indicates a median projection for the federal funds rate at year-end 2025 of 4.4 percent [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm). This projection reflects the collective view of FOMC members on the appropriate monetary policy necessary to foster economic conditions consistent with their dual mandate, which includes sustainably bringing inflation back to its 2 percent target [[^]](https://www.federalreserve.gov/monetarypolicy/fomcprojtabl20241218.htm). A moderately restrictive policy aims to continue disinflationary efforts. The projected 2.2 percent core PCE inflation rate for year-end 2025, being slightly above target, suggests FOMC participants view a moderately restrictive monetary policy stance, as implied by the 4.4 percent median federal funds rate projection, as appropriate. This approach supports continued disinflationary efforts while also promoting maximum employment. Should future economic data significantly diverge from these projections—for instance, if inflation proves more persistent or declines more rapidly—the FOMC's policy path could be adjusted through more aggressive rate cuts or a more prolonged restrictive stance, respectively. ## How Will Rent Growth Affect CPI Shelter by April 2026? Apartment List Rent Growth | Near 0% year-over-year by December 2025 [[^]](https://realestateinvestingtoday.com/apartment-lists-national-rent-report-december-2025/) | Single-Family Rent Growth | Decelerate, potentially negative by end of 2025 [[^]](https://www.cotality.com/press-releases/single-family-rents-lose-steam-at-the-end-of-2025) | CPI Shelter Growth Forecast | Around 4% year-over-year by March 2026 [[^]](https://www.globalvistahomes.com/blog/Zillow--CPI-Shelter-Forecast--March-2026) | **Leading real-time rent indices anticipate significant deceleration by Q4 2025** Leading real-time rent indices anticipate significant deceleration by Q4 2025. Projections suggest some of these indices will approach flat or even negative year-over-year growth. For instance, the Apartment List National Rent Index is expected to show near **0%** year-over-year growth by December 2025 [[^]](https://realestateinvestingtoday.com/apartment-lists-national-rent-report-december-2025/). Similarly, the Zillow Observed Rent Index (ZORI) is forecasted to continue its slowing trend, with its single-family segment potentially turning negative by the end of 2025 [[^]](https://www.cotality.com/press-releases/single-family-rents-lose-steam-at-the-end-of-2025). These trends align with reports indicating that renters experienced affordability gains by August 2025, reaching a four-year high in rental affordability by October 2025 [[^]](https://www.zillow.com/research/august-2025-rent-report-35538/). This substantial cooling in real-time rents will influence the April 2026 CPI OER. Due to the inherent lag in how Owner's Equivalent Rent (OER) reflects **market** rent fluctuations, the deceleration observed in late 2025 will translate into lower year-over-year OER figures several months later. Forecasts anticipate overall CPI shelter growth to moderate to approximately **4%** year-over-year by March 2026 [[^]](https://www.globalvistahomes.com/blog/Zillow--CPI-Shelter-Forecast--March-2026). Consequently, the Q4 2025 real-time rent trends strongly suggest that the OER component within the April 2026 CPI report will continue its decelerating trajectory, likely aligning with or falling below these forecasted levels. ## What is the CBO's Post-Election FY26 Deficit Projection? Post-Election CBO Report | The Budget and Economic Outlook: 2025 to 2035 [[^]](https://www.cbo.gov/publication/60870) | Report Publication Date | January 2025 [[^]](https://www.cbo.gov/publication/60870) | FY26 Deficit as % of GDP | Specific numerical figures not explicitly provided in research [[^]](https://www.crfb.org/blogs/cbo-releases-february-2026-budget-and-economic-outlook) | **The CBO released its initial post-election budget outlook in January 2025** The CBO released its initial post-election budget outlook in January 2025. Following the 2024 U.S. presidential and congressional elections, the Congressional Budget Office (CBO) published its first baseline projection in early 2025, titled 'The Budget and Economic Outlook: 2025 to 2035' [[^]](https://www.cbo.gov/publication/60870). This comprehensive report details the CBO's projections for the federal budget deficit, including its representation as a percentage of Gross Domestic Product (GDP) for fiscal year 2026 and subsequent years. Organizations like the Committee for a Responsible Federal Budget also provided commentary and summaries of this release [[^]](https://www.crfb.org/blogs/cbo-releases-january-2025-budget-and-economic-outlook). This outlook serves as the official baseline against which future budgetary and economic changes are measured. Specific numerical data for the FY 2026 deficit is unavailable in summaries. To determine how the early 2025 projection for the FY 2026 deficit as a percentage of GDP differs from pre-election forecasts, a comparison would typically be made between figures from the January 2025 outlook [[^]](https://www.cbo.gov/publication/60870) and prior CBO publications, such as 'An Update to the Budget and Economic Outlook: 2024 to 2034' [[^]](https://www.cbo.gov/publication/60039). While web research identifies the relevant CBO reports for both the post-election baseline and earlier comparisons, the specific numerical data points for the federal budget deficit as a percentage of GDP for fiscal year 2026, and the precise magnitude of any differences from earlier forecasts, are not explicitly provided within the titles or summary descriptions of the available research results [[^]](https://www.crfb.org/blogs/cbo-releases-february-2026-budget-and-economic-outlook). ## How Will Labor Supply Changes Impact Q1 2026 ECI? Prime-age LFPR (May 2024) | 82.8% [[^]](https://fred.stlouisfed.org/series/LNS11300060) | Net International Migration | Projected decline and continued outflows through 2025 [[^]](https://census.gov/newsroom/blogs/random-samplings/2026/01/historic-decline-in-net-international-migration.html) | Q1 2026 Employment Cost Index (ECI) | Anticipated upward pressure; [[^]](https://fred.stlouisfed.org/series/LNS11300060) | **Labor supply dynamics are expected to elevate the Employment Cost Index** Labor supply dynamics are expected to elevate the Employment Cost Index. The prime-age (25-54) labor force participation rate and net immigration flows throughout 2025 are key factors influencing the labor supply side. While a sustained high prime-age labor force participation rate could augment the domestic labor supply and ease wage pressures [[^]](https://fred.stlouisfed.org/series/LNS11300060), a plateau or decline would instead tighten it. In contrast, a projected decline in net international migration, coupled with continued outflows of unauthorized immigration through 2025, is expected to more definitively constrain the overall labor supply [[^]](https://census.gov/newsroom/blogs/random-samplings/2026/01/historic-decline-in-net-international-migration.html). Reduced immigration primarily drives labor **market** tightening, increasing wage growth. This tightening of the labor **market**, primarily driven by reduced immigration, creates a scenario where employers compete for fewer available workers, leading to stronger wage growth and increased benefits [[^]](https://www.brookings.edu/articles/macroeconomic-implications-of-immigration-flows-in-2025-and-2026-january-2026-update/). The combined effect of these dynamics points towards potential upward pressure on the Q1 2026 Employment Cost Index, with expectations of "slightly stronger" quarterly growth [[^]](https://continuumeconomics.com/a/734c6966/preview-due-april-30-us-q1-employment-cost-index-slightly-stronger-on-the-quarter-but-slower-yryr). This constrained labor supply is thus expected to be a key factor in driving services inflation in early 2026. ## How Do Economic Data Releases Influence Future Inflation Rates? April 2026 YOY Inflation Rate | Cannot be determined without access to future market data (Summary) [[^]](https://alfred.stlouisfed.org/series?seid=EXPINF2YR) | ZCIS Instrument Function | Exchanges a fixed inflation rate for the actual realized rate [[^]](https://en.wikipedia.org/wiki/Inflation_swap) | Market Expectation Proxy | Prediction markets like Polymarket offer implied probabilities [[^]](https://base.polymarket.com/event/april-inflation-us-annual) | **The precise year-over-year inflation rate for April 2026, as priced into the 2-Year Zero-Coupon Inflation Swap (ZCIS) market in January 2026, cannot be determined without accessing live market data from that future period** The precise year-over-year inflation rate for April 2026, as priced into the 2-Year Zero-Coupon Inflation Swap (ZCIS) **market** in January 2026, cannot be determined without accessing live **market** data from that future period. A ZCIS is a financial instrument designed to allow **market** participants to exchange a fixed inflation rate for the actual realized inflation rate over a specified period [[^]](https://en.wikipedia.org/wiki/Inflation_swap). While this specific forward data is not currently accessible, prediction markets, such as Polymarket, could offer real-time implied probabilities and expected values for future inflation events, serving as a proxy for **market** sentiment [[^]](https://base.polymarket.com/event/april-inflation-us-annual). Forward-looking inflation rates are highly responsive to significant economic data releases. Stronger-than-anticipated employment figures, such as non-farm payrolls, typically signal a robust economy, leading to upward revisions in inflation expectations due to potential wage growth and increased consumer demand. Conversely, weaker employment data tends to reduce these expectations. Official inflation reports, specifically the Consumer Price Index (CPI), directly influence **market** views; higher-than-expected readings drive forward inflation rates higher, while lower figures prompt downward adjustments. Other key indicators, including the 5-Year and 10-Year Breakeven Inflation Rates [[^]](https://fred.stlouisfed.org/series/T10YIE), and the Cleveland Fed's inflation expectation metrics [[^]](https://www.clevelandfed.org/indicators-and-data/inflation-expectations), consistently demonstrate this dynamic sensitivity to new economic information. ## What Could Change the Odds **Key takeaway.** Catalyst analysis unavailable. ## Key Dates & Catalysts - **Expiration:** August 11, 2026 - **Closes:** May 12, 2026 ## Decision-Flipping Events - Catalyst analysis unavailable. ## Related Research Reports - [China overtakes USA’s economy by 2030?](/markets/economics/growth/china-overtakes-usa-s-economy-by-2030/) - [Costco raises hot dog combo price?](/markets/economics/inflation/costco-raises-hot-dog-combo-price/) - [Next Fed rate hike?](/markets/economics/fed/next-fed-rate-hike/) - [US gas prices on Apr 29, 2026](/markets/economics/oil-and-energy/us-gas-prices-on-apr-29-2026/) ## Historical Resolutions **Historical Resolutions:** 20 markets in this series **Outcomes:** 1 resolved YES, 19 resolved NO **Recent resolutions:** - KXECONSTATCPIYOY-26MAR-T3.5: NO (Apr 10, 2026) - KXECONSTATCPIYOY-26MAR-T3.4: NO (Apr 10, 2026) - KXECONSTATCPIYOY-26MAR-T3.3: YES (Apr 10, 2026) - KXECONSTATCPIYOY-26MAR-T3.2: NO (Apr 10, 2026) - KXECONSTATCPIYOY-26MAR-T3.1: NO (Apr 10, 2026) ## Disclaimer This content is for informational and educational purposes only and does not constitute financial, investment, legal, or trading advice.
