Cross-platform data from Kalshi, Polymarket, and PredictIt — built for reporters who need a defensible price, not a screenshot.
These tools are live and ready to use.
Interactive docs for our cross-platform data API. Search markets, pull odds history, check liquidity, and find arbitrage — all from one normalized endpoint.
Paste a draft and instantly match its claims to live markets across platforms. See where your numbers hold up — and where they don't.
Overlay price moves with headline moments. Show your editor when a market reacted, not just where it ended up.
Instantly assess whether a price is backed by real depth or sitting on a thin book. Don't cite noise.
Shipping in phases, starting with the highest-leverage newsroom workflows.
See a story that doesn't have a prediction market yet? Flag it. We'll route it to the platforms.
Prediction markets are useful in reporting when they're framed honestly. That means understanding both the price and the market structure behind it.
A 62% price means very different things in a deep market versus a sleepy one. We surface the context so you can tell the difference.
When platforms disagree, that spread is worth investigating — different traders, different liquidity, or different contract wording.
Find the right market, get a defensible price, and understand the cross-platform picture — in minutes, not hours.
A newsroom that only checks one venue is going to miss pricing disagreements, structural quirks, and what the broader market actually believes.
This isn't a trading terminal. It's reporting infrastructure.
