Frequently Asked Questions

What is Polymarket?

Polymarket is a decentralized prediction market platform where users trade on the outcomes of real-world events. Prices reflect the crowd's probability estimate. PredTerminal tracks all Polymarket markets and whale activity.

What is Kalshi?

Kalshi is a CFTC-regulated prediction market exchange based in the US. It offers event contracts on politics, economics, weather, and more. PredTerminal combines Kalshi data with Polymarket for cross-platform intelligence.

How does cross-platform arbitrage work?

When Polymarket and Kalshi offer the same market but at different prices, there is an arbitrage opportunity. For example, if Polymarket says YES at 60 cents and Kalshi says YES at 55 cents, you can buy cheaper and sell higher. PredTerminal automatically scans for these gaps.

What are whale bets?

Whale bets are large trades (typically $10,000+) made by big players. These bets often signal informed money entering a market. When multiple whales bet the same way on the same market, it is a strong conviction signal.

What do I get with Pro?

Pro gives you real-time whale bets (no delay), access to all markets (not just featured), arbitrage alerts, top trader copy signals, 5 custom alerts, email digests, and zero data throttling. Everything you need to trade prediction markets with an edge.
