July Inflation US - Annual

Platform comparison

Market context

US inflation for the 12 months to July 2026 will be set by the Bureau of Labour Statistics’ August release, with the current crowd-implied probability on this contract at just 2% for **YES**, which is far below the kind of pricing usually seen when traders think the annual print will land near the market’s central forecast. That makes the contract a clear outlier versus the broader consensus picture: June’s CPI came in at 3.5% year on year, after 4.2% in May, and several July previews point to a modest reacceleration or at least sticky headline inflation rather than a sharp move back to very low single digits.[4][15][2]

Recent cross-platform signals are not aligned. Financial Juice’s July prep framed the median expectation for July headline CPI at 3.8%, with a 3.7% to 4.2% range, while MUFG and the Cleveland Fed’s nowcasting work both pointed to a July reading around the mid-3s, and Truflation’s real-time estimate was 3.9%.[2][5][1][6] By contrast, some longer-range forecasting sites have shown materially higher end-of-month levels, but those are model outputs rather than tradable consensus and are less useful than live market pricing. The combination suggests that a 2% YES price is not just sceptical; it is pricing a very low probability of the annual CPI still being above the contract’s threshold by July 2026.[3][7]

For traders, the key catalyst is the BLS CPI release scheduled for 12 August 2026 at 8:30 a.m. ET, which will settle the market directly.[16] The immediate dependencies are the monthly BLS print, especially the unadjusted year-on-year headline rate, and the final run-up in energy, shelter, and services inflation that can shift the last few tenths. Reuters noted in July that upside risks remained even after the softer June report, which matters because this contract is about the annual comparison rather than a single monthly move.[15]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
