How this service works
Markets whose implied probability moved the most in the last 24h — what the crowd suddenly changed its mind about. Filtered by minimum volume.
Output
A ranked list of prediction markets (up to the requested limit) sorted by magnitude of implied probability change over the last 24 hours, each including the market name, current implied probability, the size of the probability shift, 24h trading volume, and likely the platform (Polymarket/Kalshi). Only markets meeting the minimum volume threshold are included.
Example use cases
Daily sentiment shift briefing
“Give me the top 10 prediction markets that had the biggest probability swings today, filtering for at least $25,000 in 24-hour volume — I want to see what the crowd is rapidly repricing.”
High-stakes political event monitoring
“Which political or macro prediction markets are seeing the most dramatic crowd sentiment shifts right now? Show me up to 25 movers with a minimum of $100,000 in volume so I know I'm looking at serious money.”
Contrarian trading signal scan
“Pull the 15 prediction markets with the biggest implied probability changes in the last day — I'm looking for overreactions or sudden narrative flips where the crowd may have changed its mind too fast. Use a minimum volume of $10,000.”
Technical details
Endpoint
GEThttps://df-data-agent.vercel.app/api/v1/predictions/movers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to detect sudden crowd sentiment shifts in prediction markets rather than just seeing the highest-volume or highest-probability markets. It is ideal for monitoring narrative flips, contrarian signals, or breaking-news repricing events. If you want a broad snapshot of active markets rather than movers, prefer the sibling highest-volume endpoint instead.
Side effects
- No markets meet the min_volume threshold — returns empty list
- limit out of range (must be 1–100) — validation error
- Payment failure or missing x402 payment header — 402 response
- Service downtime on Vercel deployment — 5xx error
- Stale data if upstream Polymarket/Kalshi feeds are delayed
