July Inflation US - Monthly

Platform comparison

Market context

The Bureau of Labour Statistics will release its Consumer Price Index report for July 2026 on 12 August 2026 at 8:30 AM ET, disclosing the one-month seasonally adjusted percentage change in the CPI-U. This figure measures inflation's monthly pulse across urban consumer goods and services, from petrol and groceries to rent and medical care. The market currently shows zero probability assigned to any YES outcome, suggesting traders expect a specific numerical range or are awaiting clearer guidance on what constitutes a winning resolution threshold.

Monthly CPI changes typically range between −0.5% and +0.8% in normal economic conditions, though seasonal adjustments can produce tighter bands. During 2021–2022, monthly increases regularly exceeded 1%, whilst 2023–2024 saw moderation toward 0.2–0.4% monthly gains. The zero probability reading here likely reflects either an unusually narrow resolution band or insufficient clarity on the exact threshold that triggers a YES settlement, making historical volatility less predictive than the specific terms of this contract.

Traders should monitor Federal Reserve communications through August, particularly any signals about interest rate expectations that might influence inflation momentum heading into July's data. Energy prices, wage growth reports, and shelter cost trends in the weeks before the BLS release will shape market positioning. The settlement window closes just after the official release time, leaving minimal room for post-announcement trading adjustments.

UK Frequently Asked Questions

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
