`kalshi_top_markets`

Pack: kalshi · Endpoint: https://gateway.pipeworx.io/kalshi/mcp

Ranking / leaderboard of Kalshi’s most-traded markets right now — use this for “what is the highest volume prediction market on Kalshi”, “most traded Kalshi market”, or any top-N-by-activity question. Kalshi’s /markets endpoint has NO server-side sort and its raw listing is 99%+ algorithmically-generated multivariate combo markets with zero volume, so paging through it would surface junk. This instead discovers real, currently-active markets via Kalshi’s own search/relevance index, then re-ranks the leaders using each market’s authoritative live volume/price detail. Returns title, ticker, event_ticker, volume, volume_24h, open_interest, liquidity, yes/no price (cents), close_time, as_of, and source, sorted highest-first. Not an exhaustive scan of every one of Kalshi’s ~14,000 series — see method and candidates_considered in the response for the disclosed scan size.

Parameters

Name	Type	Required	Description
`by`	string	no	volume (default, all-time contracts traded) \| volume_24h \| open_interest \| liquidity
`limit`	number	no	1-50 (default 10)
`status`	string	no	”open” (default — only markets not yet past close_time) \| “any” (include markets whose close_time has passed, still excludes settled/resulted ones)
