Prediction markets let you trade on real-world events. Think of them as a stock market for outcomes — instead of buying shares in a company, you buy shares in whether something will happen.
Every prediction market is a yes/no question. For example: "Will the Fed cut rates in June 2026?"
You can buy YES shares or NO shares. Each share pays out $1.00 if you're right, and $0.00 if you're wrong.
If you buy YES at 62¢ and the Fed does cut rates, your shares are worth $1.00. That's a 61% return on your investment.
Prices ARE probabilities. A share trading at 75¢ means the market thinks there's a 75% chance the event happens. The further the price is from 50¢, the stronger the consensus.

When someone drops $50K+ on a single outcome, they usually know something. Whale bets are the highest-signal indicator in prediction markets. PredTerminal tracks every $10K+ bet across both Polymarket and Kalshi in real-time.
Pro tip: The most valuable signal is when multiple whales independently bet the same way on the same market within a short window. That's coordinated conviction.
The same event can have different prices on Polymarket vs Kalshi. When the gap is wide enough, you can profit regardless of the outcome by buying YES cheap on one platform and NO cheap on the other.
PredTerminal's live feed automatically detects these price gaps.
