## Market Behavior & Price Dynamics

The price for this market has been entirely static, holding at a 99.0% probability for a "YES" outcome since trading began. The chart displays a completely flat, sideways trend with no significant price movements, spikes, or drops to analyze. Despite news context indicating that economists forecast continued high inflation driven by energy prices for the May 2026 CPI report, this information has had no apparent impact on the market's price, as no trades have registered a reaction.

The most critical feature of this market is the complete lack of trading activity, with a total volume of zero contracts traded. This indicates the market is illiquid and that the 99.0% price does not reflect an active consensus or any level of trader conviction. As there has been no trading, standard technical analysis concepts such as support or resistance levels are not applicable. The chart suggests that while the nominal price indicates extremely high confidence in the outcome, this is not supported by any market participation. The price reflects an opening position rather than an active sentiment derived from buying and selling.

## Contract Snapshot

This market resolves to "Yes" if the Gasoline (All Types) in U.S. City Average Consumer Price Index for May 2026 is above 377, based on FRED series CUSR0000SETB01. If the index is 377 or below, the market resolves to "No." The market opened on May 29, 2026, and will close early upon the release of the economic data, or by June 10, 2026, at 8:29 am EDT, with payouts projected 30 minutes after closing.

## Market Discussion

Prediction markets are actively trading the May 2026 U.S. gasoline CPI, with contracts speculating on thresholds ranging from 365 to 390 cents as of June 9, 2026 [[^]](https://kalshi.com/markets/kxusgascpi/us-gasoline-cpi-in-month/kxusgascpi-26jun10)[[^]](https://www.coinbase.com/predictions/event/KXUSGASCPI-26JUN10)[[^]](https://www.predictionnewsnetwork.com/p/gasoline-cpi-may-2026-no-kalshi-whale)[[^]](https://pdata.world/events/kalshi/KXUSGASCPI-26JUN10).

## How might Federal Reserve monetary policy announcements in early 2026 influence economic activity and consumer demand for gasoline ahead of the May CPI reading?

FOMC Target Range | 3.5% to 3.75% (early 2026) [[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260429a.htm)[[^]](https://www.federalreserve.gov/monetarypolicy/fomcminutes20260429.htm)[[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260318a.htm)[[^]](https://www.federalreserve.gov/newsevents/speech/files/jefferson20260326a.pdf) |
Policy Rationale | Elevated inflation and Middle East uncertainty [[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260429a.htm)[[^]](https://www.federalreserve.gov/monetarypolicy/fomcminutes20260429.htm)[[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260318a.htm)[[^]](https://www.federalreserve.gov/newsevents/speech/files/jefferson20260326a.pdf) |
Gasoline Price Impact | Regressive economic pressure on lower-income households [[^]](https://www.bostonfed.org/publications/current-policy-perspectives/2026/reassessing-us-economys-vulnerability-oil-shocks.aspx)[[^]](https://libertystreeteconomics.newyorkfed.org/2026/05/same-shock-different-roads-a-k-shaped-pattern-at-the-pump/) |

**FOMC maintained cautious monetary policy due to inflation and global events**

FOMC maintained cautious monetary policy due to inflation and global events.
Throughout early 2026, the Federal Open **Market** Committee (FOMC) held its federal funds target range at **3.5%** to **3.75%**. This cautious and data-dependent policy stance was primarily a response to elevated inflation, which was partly attributed to global energy prices, and persistent uncertainties stemming from developments in the Middle East [[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260429a.htm)[[^]](https://www.federalreserve.gov/monetarypolicy/fomcminutes20260429.htm)[[^]](https://www.federalreserve.gov/newsevents/pressreleases/monetary20260318a.htm)[[^]](https://www.federalreserve.gov/newsevents/speech/files/jefferson20260326a.pdf).

Rising gasoline prices pressured consumers, raising inflation expectations.
Concurrently, rising gasoline prices in early 2026 exerted a regressive economic pressure, particularly affecting the real consumption patterns of lower-income households and contributing to a K-shaped consumption pattern [[^]](https://www.bostonfed.org/publications/current-policy-perspectives/2026/reassessing-us-economys-vulnerability-oil-shocks.aspx)[[^]](https://libertystreeteconomics.newyorkfed.org/2026/05/same-shock-different-roads-a-k-shaped-pattern-at-the-pump/). These increased prices also acted as a prominent price signal, risking an elevation of consumer inflation expectations and potentially constraining the Federal Reserve's capacity to ease monetary policy [[^]](https://siepr.stanford.edu/news/Iran-war-gas-prices-consumers-economy-affordability)[[^]](https://www.kansascityfed.org/documents/9243/EconomicReviewV107N4CakirMelekDillonSmith.pdf)[[^]](https://libertystreeteconomics.newyorkfed.org/2026/05/same-shock-different-roads-a-k-shaped-pattern-at-the-pump/).

## How does the historical volatility of the gasoline CPI index compare to the Core CPI index over the 2024-2025 period?

Gasoline CPI Volatility | Consistently substantially higher than Core CPI index [[^]](https://www.sciencedirect.com/science/article/pii/S0165176524003549)[[^]](https://fredblog.stlouisfed.org/2014/08/cpi-component-volatility/)[[^]](https://www.dallasfed.org/-/media/documents/research/papers/2022/wp2224.pdf) |
Reason for Volatility Difference | Gasoline prices respond to energy market shocks; Core CPI excludes volatile food and energy components [[^]](https://www.sciencedirect.com/science/article/pii/S0165176524003549)[[^]](https://fredblog.stlouisfed.org/2014/08/cpi-component-volatility/)[[^]](https://www.dallasfed.org/-/media/documents/research/papers/2022/wp2224.pdf) |
2024-2025 Volatility Data | Specific historical volatility data for 2024-2025 is not available [[^]](https://www.sciencedirect.com/science/article/pii/S0165176524003549)[[^]](https://fredblog.stlouisfed.org/2014/08/cpi-component-volatility/)[[^]](https://www.dallasfed.org/-/media/documents/research/papers/2022/wp2224.pdf) |

**Historically, gasoline CPI volatility significantly exceeds that of the Core CPI**

Historically, gasoline CPI volatility significantly exceeds that of the Core CPI. This substantial difference arises because gasoline prices are highly susceptible to sharp fluctuations from energy **market** shocks. In contrast, the Core CPI is specifically constructed to exclude these volatile food and energy components, thereby offering a clearer indication of underlying inflation trends [[^]](https://www.sciencedirect.com/science/article/pii/S0165176524003549)[[^]](https://fredblog.stlouisfed.org/2014/08/cpi-component-volatility/)[[^]](https://www.dallasfed.org/-/media/documents/research/papers/2022/wp2224.pdf).

Specific 2024-2025 volatility data for these indices is unavailable. While the general historical relationship between the gasoline CPI and Core CPI indices is well-established, the provided information does not contain explicit data regarding their historical volatility specifically for the 2024-2025 period [[^]](https://www.sciencedirect.com/science/article/pii/S0165176524003549)[[^]](https://fredblog.stlouisfed.org/2014/08/cpi-component-volatility/)[[^]](https://www.dallasfed.org/-/media/documents/research/papers/2022/wp2224.pdf).

## Which high-frequency datasets from the EIA and AAA serve as the most reliable leading indicators for the official May 2026 BLS gasoline CPI report?

BLS Gasoline CPI data source | Crowdsourced secondary source dataset (since June 2021) [[^]](https://fred.stlouisfed.org/series/CUSR0000SETB01)[[^]](https://www.bls.gov/cpi/additional-resources/case-study-gasoline-price-data.htm)[[^]](https://www.bls.gov/cpi/factsheets/acm-gasoline.htm) |
Most reliable EIA indicator for BLS CPI | Monthly average of weekly retail prices (EIA) [[^]](https://www.econ.iastate.edu/ask-an-economist/did-bls-consumer-price-index-new-release-july-contain-major-error-gasoline-prices)[[^]](https://www.bls.gov/opub/btn/volume-2/pdf/measures-of-gasoline-price-change.pdf) |
Reliable high-frequency gasoline tracker | AAA's daily pump price data [[^]](https://www.bls.gov/cpi/factsheets/motor-fuel.htm)[[^]](https://www.econ.iastate.edu/ask-an-economist/did-bls-consumer-price-index-new-release-july-contain-major-error-gasoline-prices) |

**The BLS Gasoline CPI relies on crowdsourced daily price data**

The BLS Gasoline CPI relies on crowdsourced daily price data. Since June 2021, the official BLS Gasoline CPI has used a crowdsourced secondary source dataset for its calculations [[^]](https://fred.stlouisfed.org/series/CUSR0000SETB01)[[^]](https://www.bls.gov/cpi/additional-resources/case-study-gasoline-price-data.htm)[[^]](https://www.bls.gov/cpi/factsheets/acm-gasoline.htm). This dataset provides daily, high-frequency price data that is similar to those used by private trackers.

EIA weekly retail prices reliably predict the BLS gasoline CPI. When using data from the EIA, the most reliable leading indicator for predicting the monthly BLS gasoline CPI report is the monthly average of its weekly retail prices, which shows a close correlation with the BLS index once timing differences are accounted for [[^]](https://www.econ.iastate.edu/ask-an-economist/did-bls-consumer-price-index-new-release-july-contain-major-error-gasoline-prices)[[^]](https://www.bls.gov/opub/btn/volume-2/pdf/measures-of-gasoline-price-change.pdf). While the EIA's Weekly Retail Gasoline and Diesel Prices offer key high-frequency metrics, they require careful reconciliation, such as averaging, to align with the monthly, calendar-based BLS CPI index due to their weekly release schedule and specific coverage days [[^]](https://www.eia.gov/dnav/pet/hist/LeafHandler.ashx?n=PET&s=EMM_EPMR_PTE_NUS_DPG&f=W&utm_source=newsletter&utm_medium=email&utm_campaign=newsletter_axiosgenerate&stream=top)[[^]](https://fred.stlouisfed.org/series/GASREGW)[[^]](https://www.bls.gov/cpi/factsheets/motor-fuel.htm)[[^]](https://www.eia.gov/petroleum/gasdiesel/gas_proc-methods.php).

AAA daily pump prices also track gasoline prices reliably. Additionally, AAA's daily pump price data also serves as a reliable high-frequency tracker for gasoline prices [[^]](https://www.bls.gov/cpi/factsheets/motor-fuel.htm)[[^]](https://www.econ.iastate.edu/ask-an-economist/did-bls-consumer-price-index-new-release-july-contain-major-error-gasoline-prices). Any discrepancies observed between AAA data and the BLS CPI are mainly attributed to differences in sampling methodology and the temporal nature of comparing daily snapshots versus monthly averages.

## What do pricing trends in the RBOB gasoline futures market for Q2 2026 indicate about professional traders' expectations for wholesale gas prices?

RBOB Futures Q2 2026 Trend | Bullish bias as of June 2026 [[^]](https://www.spartacommodities.com/market-outlook/bullish-bias-maintained-ta-arb-spreads-gc-cbob-rbob-july-rbob-outlook/)[[^]](https://www.spartacommodities.com/market-outlook/rbob-spreads-bullish-as-houston-re-establishes-market-share-in-latam-on-a-narrowing-ta-arb-while-prompt-e-w-spreads-rally/)[[^]](https://www.argusmedia.com/en/news-and-insights/energy-and-commodity-podcasts/summer-driving-season-outlook-podcast) |

**Overall market sentiment for Q2 2026 RBOB futures is bullish**

Overall **market** sentiment for Q2 2026 RBOB futures is bullish. As of June 2026, RBOB gasoline futures for Q2 2026 showed a bullish bias. This trend is driven by seasonal inventory draws, increased demand for US exports to Latin America, and tight domestic supply-demand dynamics that necessitate ongoing imports into the New York Harbor [[^]](https://www.spartacommodities.com/**market**-outlook/bullish-bias-maintained-ta-arb-spreads-gc-cbob-rbob-july-rbob-outlook/)[[^]](https://www.spartacommodities.com/**market**-outlook/rbob-spreads-bullish-as-houston-re-establishes-**market**-share-in-latam-on-a-narrowing-ta-arb-while-prompt-e-w-spreads-rally/)[[^]](https://www.argusmedia.com/en/news-and-insights/energy-and-commodity-podcasts/summer-driving-season-outlook-podcast).

Traders manage risks, but **market** signals hint at maturing price uptrends. Professional traders are actively managing risks associated with geopolitical news and regulatory constraints, such as the implementation of higher RVP RBOB specifications. This has led to widened gasoline spreads in specific regions, even with emergency fuel waivers in place [[^]](https://www.spartacommodities.com/**market**-outlook/bullish-bias-maintained-ta-arb-spreads-gc-cbob-rbob-july-rbob-outlook/)[[^]](https://www.argusmedia.com/en/news-and-insights/energy-and-commodity-podcasts/summer-driving-season-outlook-podcast). Commitments of Traders (COT) reports from early May 2026 indicated a buildup of managed money (speculative) long positions alongside a decline in total **market** open interest. Professional traders interpret this as a potential sign that the gasoline price uptrend is maturing or becoming exhausted [[^]](https://www.getarcresearch.com/reports/gasoline-rbob-cftc-commodity-report-2026-05-08).

Prediction markets anticipate moderate gasoline CPI for May 2026. Prediction markets for the US Gasoline CPI for May 2026 suggest expectations of moderate, rather than runaway, price levels. There is a high degree of **confidence**, approximately **99%**, that the index will remain above 330. However, the odds for thresholds like 390 are priced as unlikely when compared to earlier peak projections [[^]](https://www.coinbase.com/predictions/event/KXUSGASCPI-26JUN10)[[^]](https://pdata.world/events/kalshi/KXUSGASCPI-26JUN10)[[^]](https://www.predictionnewsnetwork.com/p/gasoline-cpi-may-2026-no-kalshi-whale).

## What potential geopolitical or supply chain disruptions between Q4 2025 and Q2 2026 pose the greatest risk to gasoline price stability for the May CPI report?

Oil Supply Loss | 10–14 million barrels per day [[^]](https://www.eia.gov/todayinenergy/detail.php?id=67424)[[^]](https://taceconomics.com/wp-content/uploads/2026/04/TAC-ECONOMICS-WP_iranian-oil-shock-BGVAR-model_April2026.pdf)[[^]](https://www.brookings.edu/articles/from-chokepoint-to-crisis-the-strait-of-hormuz-and-global-oil-markets/)[[^]](https://www.cnbc.com/2026/03/09/the-us-iran-war-is-the-biggest-oil-supply-disruption-in-history.html)[[^]](https://analysis-atlas.com/research/hormuz-oil-supply-shock-2026/) |

**The most significant risk to gasoline price stability for the May 2026 CPI report stemmed from a military conflict involving Iran, which commenced on February 28, 2026**

The most significant risk to gasoline price stability for the May 2026 CPI report stemmed from a military conflict involving Iran, which commenced on February 28, 2026. This conflict led to the effective closure of the Strait of Hormuz to tanker traffic, severely disrupting global oil supply. The disruption resulted in a reduction of approximately 10–14 million barrels per day of oil supply worldwide [[^]](https://www.eia.gov/todayinenergy/detail.php?id=67424)[[^]](https://taceconomics.com/wp-content/uploads/2026/04/TAC-ECONOMICS-WP_iranian-oil-shock-BGVAR-model_April2026.pdf)[[^]](https://www.brookings.edu/articles/from-chokepoint-to-crisis-the-strait-of-hormuz-and-global-oil-markets/)[[^]](https://www.cnbc.com/2026/03/09/the-us-iran-war-is-the-biggest-oil-supply-disruption-in-history.html)[[^]](https://analysis-atlas.com/research/hormuz-oil-supply-shock-2026/).

This substantial reduction in oil supply prompted a rapid pass-through of crude oil price spikes to the gasoline **market**, pushing US retail gasoline prices to record highs in real terms [[^]](https://www.eia.gov/todayinenergy/detail.php?id=67424)[[^]](https://ag.purdue.edu/commercialag/home/wp-content/uploads/2026/04/cpi_brief.pdf)[[^]](https://www.wichitaliberty.org/economics/cpi-march-2026-inflation-report/)[[^]](https://analysis-atlas.com/research/hormuz-oil-supply-shock-2026/). The CPI gasoline indices recorded unprecedented monthly increases in March 2026, including a **21.2%** seasonally adjusted jump [[^]](https://www.eia.gov/todayinenergy/detail.php?id=67424)[[^]](https://ag.purdue.edu/commercialag/home/wp-content/uploads/2026/04/cpi_brief.pdf)[[^]](https://www.wichitaliberty.org/economics/cpi-march-2026-inflation-report/)[[^]](https://analysis-atlas.com/research/hormuz-oil-supply-shock-2026/). The May 2026 CPI report, which will reflect April 2026 data, hinges on whether gasoline prices moderated following an early April ceasefire or continued at the elevated levels observed in March [[^]](https://taceconomics.com/wp-content/uploads/2026/04/TAC-ECONOMICS-WP_iranian-oil-shock-BGVAR-model_April2026.pdf)[[^]](https://ag.purdue.edu/commercialag/home/wp-content/uploads/2026/04/cpi_brief.pdf)[[^]](https://www.wichitaliberty.org/economics/cpi-march-2026-inflation-report/).

## What Could Change the Odds

**The US Consumer Price Index (CPI) for May 2026 is scheduled to be released by the Bureau of Labor Statistics (BLS) on Wednesday, June 10, 2026, at 8:30 a.m.** ET [[^]](https://www.bls.gov/schedule/news_release/cpi.htm)[[^]](https://www.bls.gov/cpi/)[[^]](https://www.bls.gov/schedule/2026/06_sched.htm)[[^]](https://regimeanalysis.com/economic-calendar/month-of/june-2026). **Market** consensus forecasts for the May CPI anticipate a year-over-year headline increase of approximately **4.2%** and a month-over-month increase of **0.5%**–**0.55%**, driven by energy and sticky core services [[^]](https://www.tradingkey.com/analysis/economic/indicators/261955113-us-may-cpi-preview-rising-inflation-fed-rate-hike-us-stocks-dollar-gold-reaction-tradingkey)[[^]](https://www.exponential-tech.ai/post/may-2026-cpi-forecast)[[^]](https://forex.tradingcharts.com/economic_calendar/2026-06-08.html?code=USD). The May CPI gasoline component is influenced by the lagged pass-through of crude oil prices from the first three weeks of May; although spot gasoline prices began to roll over in late May, this decline is expected to appear in later reports [[^]](https://realinvestmentadvice.com/resources/blog/the-cpi-math-driving-inflation-works-two-ways/)[[^]](https://www.exponential-tech.ai/post/may-2026-cpi-forecast).

**Prediction markets show high probability for continued inflationary pressure [[^]](https://www.tradingkey.com/analysis/economic/indicators/261955113-us-may-cpi-preview-rising-inflation-fed-rate-hike-us-stocks-dollar-gold-reaction-tradingkey)[[^]](https://www.exponential-tech.ai/post/may-2026-cpi-forecast)[[^]](https://forex.tradingcharts.com/economic_calendar/2026-06-08.html?code=USD).** A higher-than-expected CPI report is viewed as a bearish catalyst for stocks and potentially bullish for the US Dollar, as it reinforces "higher-for-longer" interest rate expectations and the potential for further Federal Reserve rate hikes [[^]](https://www.tradingkey.com/analysis/economic/indicators/261955113-us-may-cpi-preview-rising-inflation-fed-rate-hike-us-stocks-dollar-gold-reaction-tradingkey)[[^]](https://regimeanalysis.com/economic-calendar/month-of/june-2026). Upcoming key dates include the FOMC meeting scheduled for June 16–17, 2026, which follows the CPI release and is a critical point for **market** volatility regarding interest rate policy [[^]](https://pdata.world/events/kalshi/KXUSGASCPI-26JUN10)[[^]](https://regimeanalysis.com/economic-calendar/month-of/june-2026).
