ECB Interest Rates: July 2026

Platform comparison

Market context

The European Central Bank’s July 2026 meeting has already been resolved as a **hold**, with the deposit facility rate left at **2.25%** after the June increase to that level. That makes the market’s current **0% YES** crowd probability broadly consistent with the official outcome and with the way prediction markets typically price a meeting once the ECB statement is out, even if some pre-meeting desks had left room for another move.

The key comparison point is June, when the ECB raised all three policy rates by **25 basis points**; official rates then moved to 2.25%, 2.40% and 2.65% respectively. Reuters reported before the July decision that ECB officials were leaning towards a pause if energy prices stayed contained, while some analysts and market commentary had still entertained the possibility of further tightening later in 2026. That split matters because the contract only settles on the **change** in the deposit rate at the July meeting, not on the broader policy path.

For traders, the catalysts were the ECB’s meeting schedule, the accompanying statement, and any guidance on inflation or energy shocks, especially given the market’s sensitivity to Middle East-driven oil moves. Eurozone inflation, wage data and any shift in the ECB’s language about “appropriate” rates were the main dependencies, but the official release has now fixed the outcome for settlement purposes. The meaningful divergence was therefore not between sportsbook lines and prediction markets after the fact, but between pre-meeting analyst debate and the now-confirmed hold.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
