How this service works
Real-time alerts on whale traders on Polymarket. Heuristic Insider Watch, wallet scoring 0–100, Bloomberg-style web terminal. Free plan included.
Output
A JSON object containing a list of up to 100 recent whale trades on Kalshi, each with market ticker, market title, category, side (yes/no), price, USD size, and timestamp. Also includes metadata: platform, data delay in minutes (15), whale minimum USD threshold ($1,000), a disclaimer that trades are anonymous institutional flow not attributed to specific traders, and an outcome_verified flag (false).
Example use cases
Monitor whale bets on Fed rate markets
“What are the biggest trades happening right now on Kalshi's Fed funds rate markets? I want to see which side whales are taking and at what price.”
Daily prediction market briefing
“Give me a morning briefing of the last 20 whale trades on Kalshi — I want to know what large traders are betting on across economics markets today.”
Spot unusual large-trade activity
“Are there any unusually large trades on Kalshi right now? Show me up to 100 whale trades so I can spot any concentrated institutional flow in a single market.”
Technical details
Endpoint
GEThttps://api.predge.io/v1/kalshi/whales/latestWhen to prefer
Choose this endpoint when you need the most recent large-trade flow on Kalshi prediction markets specifically — it surfaces anonymized institutional-size trades ($1,000+ USD) with a 15-minute delay. Prefer this over Polymarket-focused endpoints when your user cares about Kalshi markets (e.g. Fed rate, economics). Note that trades are anonymous and not outcome-verified, so this is a flow-signal tool, not a verified insider alert.
Side effects
- Limit parameter out of range (must be 1–100) returns validation error
- Payment not included or insufficient USDC causes 402 Payment Required
- No trades available in current window returns empty trades array with count 0
- Kalshi public API unavailable causes upstream data gap
- Stale data if Kalshi feed is delayed beyond the 15-minute window
