FAQ

About

What is predictions.io? One dashboard for every prediction market — Kalshi, Polymarket, Manifold, Metaculus, and more. Compare prices, track whales, follow top traders, manage your portfolio. No more switching between apps.

Is predictions.io a prediction market itself? No. We don't hold funds or take trades. We're the aggregation layer on top — like a Bloomberg terminal for prediction markets.

Who is it for? Active traders on Kalshi and/or Polymarket who want cross-platform price comparison, whale alerts, and a unified portfolio view.

Platforms

Which platforms do you support? Kalshi, Polymarket, Manifold, and Metaculus — with more being added.

Why does the same event show different odds on different platforms? Each platform has its own traders and liquidity, so prices diverge. We surface those gaps in real time.

Features

What is the Whales feature? It tracks large trades across all platforms. Big money moves prices — we show you where it's going.

Can I track my portfolio across platforms? Yes. One P&L view across all your positions, no spreadsheet required.

Can I follow top traders? Yes. See their positions and track record across platforms.

What's coming next? Homepage price comparison, Big Movers section, volume tabs, sorting, and more. Follow @predictions_app on X for updates.

Access

Is it free? Yes. No subscription needed.

Is there a mobile app? Yes, on Google Play. Search "predictions.io."

Do I need to link my trading accounts? Only for portfolio tracking. Browsing markets and whale data requires no account connection.

Trading

Do you execute trades? No. Read-only. All trading stays on your chosen platform.

Is this gambling? No. Kalshi is a CFTC-licensed financial exchange. We're an analytics tool for traders and investors.
