July Inflation US - Monthly

Platform comparison

Market context

The Bureau of Labour Statistics will release the July 2026 Consumer Price Index on 12 August 2026, reporting the one-month seasonally adjusted change in the CPI-U. This monthly reading captures price movements across the full basket of goods and services tracked by the BLS and serves as a key input for Federal Reserve policy decisions and economic forecasting. The crowd currently assigns zero probability to any particular outcome, suggesting either extreme uncertainty about the inflation trajectory or insufficient historical anchoring for this specific monthly reading.

Monthly CPI changes typically cluster between −0.1% and +0.4% in normal economic conditions, with seasonal patterns particularly pronounced in summer months when energy and food prices often shift. The comparable July 2025 reading showed a 0.2% monthly increase; July 2024 recorded 0.1%. These modest single-digit monthly moves have become the baseline expectation following the Federal Reserve's rate-hiking cycle of 2022–2023, which brought headline inflation from 9.1% year-on-year down towards the 2% target by early 2025.

Traders should monitor labour market reports through June and early July, which will signal wage pressures ahead of the CPI release. Energy prices in July—particularly crude oil and petrol—will be critical, as they drive outsized monthly volatility in headline inflation. Any unexpected surge in shelter costs, which comprise roughly one-third of the index, could push the monthly reading above recent norms. The Federal Reserve's policy stance and forward guidance in the months preceding August will also shape market expectations for what constitutes "hot" or "cool" inflation data at that point.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for July Inflation US - Monthly plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

UK Frequently Asked Questions

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
