Kalshi traders expect US inflation to stay high after a likely 2026 peak
Traders on Kalshi, a prediction market, expect US inflation to remain high even if it has already peaked this year.
They forecast that September consumer prices rose 3.6% from a year earlier, up from 3.4% in August.
That September figure is due Wednesday, and the forecast matches economists’ estimate cited in the reports.
The inflation contracts are settled using official data from the US Bureau of Labor Statistics.
Traders put just under a one-in-three chance on inflation reaching a new high in 2026.
They also expect core inflation, which excludes food and energy, to stay elevated, with only a 6% chance it falls below 2.2% this year.
Persistent inflation matters because it remains above the Federal Reserve’s 2% goal and could affect its policy decisions.
Kalshi traders expect US inflation to remain elevated through the rest of 2026, despite thinking it has likely peaked for the year.
The market puts the expected September year-over-year consumer price index increase at 3.6%, up from 3.4% in August.
Kalshi traders assign just under one-in-three odds to inflation reaching a new high in 2026.
CNBC reports that traders expect core inflation to stay elevated, with only a 6% chance it falls below 2.2% this year.
