Reference data · prediction markets
The reference layer for prediction markets.
Clean, structured data on the markets your clients are starting to ask about. Normalized across Kalshi and Polymarket.
A new data class your clients are asking about
Macro odds, priced in real time.
Interest rates, inflation, policy, elections. A multi-billion-dollar, fast-growing source of forward-looking data.
- Regulated. The CFTC in the US and CIRO in Canada have cleared brokerages to offer them.
- Unserved. Your clients already watch these venues, but there is no aggregate, screened feed to put in front of them.
The raw data isn't built for institutions
ClearMarket normalizes all of it into one clean, screened feed you can put in front of a client with confidence.
What you get
Screen to any regime
Screen the universe to the rules your clients fall under, starting with CIRO and extendable to any jurisdiction or mandate. Filter down for client distribution, or keep the whole universe for maximum signal. See the live CIRO screen →
Clean, structured, ready to build on
Two venues, two formats, one normalized schema. Delivered by documented API and MCP, so your team integrates once and builds on top.
A clarity grade on every market
Every market graded A to C on how cleanly it settles, based on whether it commits to a named source of record. Clean and ambiguous markets separate at a glance.
The whole market, kept current
The full Kalshi and Polymarket universe, prices refreshed hourly and timestamped per market. Resolved markets are kept as settled history, not mixed into the live view. Related markets linked across venues where they exist.
Proven in the data
Resolution grading flags settlement risk.
A prediction market settles on its rules. When the rules are vague, the outcome gets contested. ClearMarket grades every market on how clearly it will settle, and the grades separate: markets we flag C are formally contested at 20 times the rate of markets we grade clean.
7,166 Polymarket markets with public dispute records, split by grade. Measured on Polymarket because its on-chain dispute record is the only one complete enough to audit; Kalshi publishes no dispute feed.
Neutral by design.
Oil producers can't publish the oil benchmark, because they trade it. Platts does.
Banks couldn't aggregate each other's CDS books without leaking positions. Markit did.
A venue can't authoritatively grade its own settlement. ClearMarket does.
Every asset class that matured did it on a neutral reference layer. Prediction markets don't have one yet. ClearMarket is that layer.
Independent of every venue, and already the reference leading AI assistants cite.
