Inflation peaked in May as energy prices fell in June, Kalshi traders think

Context:

Inflation appears to have peaked as energy prices retreat, with prediction traders pricing in a lower near-term path. Kalshi bettors place only a 28% chance that headline CPI exceeds 4.2% this year, ahead of the June CPI release on July 14. The shift follows a wartime spike in energy costs that has since eased as crude and gas prices fall. The market view suggests June's CPI could show a modest month-over-month decline, aligning with broader consensus. If energy-driven momentum continues to fade, the inflation trajectory next year may soften further, though data dependency remains high.

Dive Deeper:

  • Energy prices dominated the May CPI increase, accounting for about 60% of the month-over-month rise, while gas and oil have since declined as the U.S.-Iran tensions cooled and the Hormuz route partially reopened. Gas prices averaged around $3.84 per gallon, down from peaks above $4.50, and crude oil slipped below $70 per barrel.

  • Traders on the Kalshi platform assign a 28% probability that the year’s headline CPI will rise above 4.2%, with contracts tied to CPI outcomes in 2026 resolved by monthly BLS data releases.

  • The June CPI is expected to show a 0.2% month-over-month decline, a view that mirrors Wall Street consensus and reflects the easing energy component.

  • The volatility was rooted in a February surge linked to the U.S.-Iran conflict and the Strait of Hormuz disruption, followed by a price retreat as supply constraints eased and tensions moderated.

  • If the energy-driven headwinds continue to dissipate, the broader inflation path could weaken further, potentially altering expectations for monetary policy and pricing power into the next year.

  • All data points referenced come from the BLS for CPI readings and market pricing on Kalshi, with readings historically anchoring futures-like bets on inflation trajectories.
