A Kalshi event with every child market and its current odds, from the regulated US exchange.

Tool description as the model sees it

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, 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_ask_cents/yes_bid_cents/no_ask_cents + implied_yes_prob — required for most macro events since the nested response leaves prices null on the public unauth API). Every price ships TWO ways: *_cents rounded to the nearest cent (Kalshi’s display convention) and *_dollars at full fixed-point precision — a genuine sub-cent quote like 0.335 shows as 34 in yes_ask_cents and exactly 0.335 in yes_ask_dollars; use the dollars field for anything sizing a trade on a thin spread. implied_yes_prob is computed from the dollars value, not the rounded cents, so it carries the same precision. yes_bid_size/no_bid_size report top-of-book contract size for the two real resting sides when include_orderbook populated them from the orderbook ladder — there is no separate size for yes_ask/no_ask because those are derived prices (1 − the opposite side’s best bid), not an independent order. 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).
