Kalshi, Polymarket, and the markets moving right now — the odds, the volume, and where they disagree — in one clean dashboard. The same Delta Arc discipline, pointed at the fastest-growing corner of the market.
Prediction markets are exploding — and the information is scattered across venues. We pull it together so you can actually read it.
The most active markets across Kalshi and Polymarket in one view — elections, econ, crypto, culture. (Robinhood rides Kalshi, so it's covered too.)
The edge almost nobody surfaces: when the same event prices differently on Kalshi vs Polymarket. We flag the gap the moment it opens.
Watch the probability move and the volume surge in real time — the change, and where the momentum is carrying it.
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.
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.
Priced for the market — high signal, low commitment. Introductory pricing, may change before public launch.
