`kalshi_event`

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

AUTHORITATIVE odds from Kalshi — the only CFTC-regulated US prediction-market exchange (US persons CAN legally trade here, unlike Polymarket). Returns one event with ALL its child markets nested: event title + each market’s ticker, subtitle, yes_ask price, volume. Use when you need the full partition for an outright bet (“Fed funds in June 2026: each rate level is one market”). Pass include_orderbook=true to fetch live top-of-book for each market (slower but populates yes_bid/yes_ask/no_bid/no_ask + implied_yes_prob — required for most macro events since the nested response leaves prices null on the public unauth API). For cross-venue spreads vs Polymarket, see polymarket_kalshi_spread.

Parameters

Name	Type	Required	Description
`event_ticker`	string	yes	Kalshi event ticker, e.g. “KXFED-26OCT”
`include_orderbook`	boolean	no	Default false. When true, fetches per-market orderbook in parallel and patches in best bid/ask + recomputed implied_yes_prob. Adds ~1s for events with ~10 markets. Required when the nested response returns null prices (common for macro events on the unauth API).
