Output
A ranked list of prediction markets sorted by trading volume and liquidity, including market names, platforms, volume figures, liquidity depth, and flagged volume spikes that may indicate breaking news or unusual betting activity.
Example use cases
Monitor breaking news via market movement
“I just saw headlines about the election results. Can you check which prediction markets are seeing sudden volume spikes right now? I want to know if traders are already reacting to this.”
Find the biggest bets across all platforms
“Show me where the real money is flowing in prediction markets today. I'm looking for the markets with the deepest liquidity and largest positions — which ones are people actually putting serious capital behind?”
Detect unusual betting activity patterns
“Pull up the prediction markets that had the biggest volume changes in the last few hours. I'm trying to spot if there's coordinated or insider activity happening before major announcements.”
