The data nobody puts in one place.
Prediction markets are exploding — and the information is scattered across venues. We pull it together so you can actually read it.
All the top markets
The most active markets across Kalshi and Polymarket in one view — elections, econ, crypto, culture. (Robinhood rides Kalshi, so it's covered too.)
Cross-venue divergence
The edge almost nobody surfaces: when the same event prices differently on Kalshi vs Polymarket. We flag the gap the moment it opens.
Odds & money in motion
Watch the probability move and the volume surge in real time — the change, and where the momentum is carrying it.
Prediction markets went mainstream.
The midterm markets alone have cleared $200M+. Polymarket is now legal to trade in the US. Kalshi is regulated and growing, with Robinhood feeding off it. This is a real, liquid, fast-moving asset class — and it's only getting bigger.
What's missing isn't more venues. It's a place to read all of them at once — honestly, with the change surfaced. That's what this is.
- Aggregated across venues, not locked to one
- Change-detection on odds and volume
- Educational & informational — we show the board, you make the call
Detect the change. Direct the momentum.
Same ethos as the rest of the desk — evidence over hype, the shift caught early — applied to prediction markets instead of equities and options. One suite, one standard.
