Kalshi — Prediction Markets
Before writing queries, consult references/api-reference.md for sport codes, series tickers, and command parameters.
Quick Start
Prefer the CLI — it avoids Python import path issues:
Python SDK (alternative):
CRITICAL: Before Any Query
CRITICAL: Before calling any market endpoint, verify:
- The
sportparameter is always passed tosearch_marketsandget_todays_eventsfor single-game markets. - Prices are on a 0-100 integer scale (20 = 20% implied probability) — do not treat as American odds.
status="open"is used when querying markets to exclude settled/closed markets.
Without the sport parameter:
Important Notes
- On Kalshi, "Football" = NFL. For football/soccer (EPL, La Liga, etc.), use sport codes:
epl,ucl,laliga,bundesliga,seriea,ligue1,mls,worldcup. - Formula 1 uses sport code
f1(drivers'/constructors' champion plus per-Grand-Prix race, podium, pole, fastest-lap, head-to-head and sprint series). - Market tickers are not always
<event_ticker>-<suffix>. Kalshi mints some with a different stem, e.g.KXATP-26-SHAsits inside eventKXATP-26USO(2026 US Open men's singles) next toKXATP-26USO-SIN. That is Kalshi's real ticker: pass it verbatim toget_market, and group markets by theirevent_tickerfield, never by parsing the ticker. - Prices are probabilities. A
last_priceof 20 means 20% implied probability. Scale is 0-100 (not 0-1 like Polymarket). - Always use
status="open"when querying markets, otherwise results include settled/closed markets. - Shared interface with Polymarket:
search_markets(sport=...),get_todays_events(sport=...), andget_sports_config()work the same way on both platforms.
Workflows

Futures Market Check

last_pricedescending. - Present top contenders with probability and volume.
Market Price History
- Get market ticker from
search_markets --sport=nba. get_market_candlesticks --series_ticker=<s> --ticker=<t> --start_ts=<start> --end_ts=<end> --period_interval=60- Present OHLC with volume.

Troubleshooting
Error: search_markets returns 0 results
Cause: The sport parameter is missing — without it, search only returns high-volume futures and misses single-game markets
Solution: Always pass sport='<code>' to search_markets. Check references/api-reference.md for valid sport codes
Error: Markets returned include settled/expired contracts
Cause: status parameter is not set
Solution: Always pass status="open" to filter to open markets only
Error: Series ticker returns no results
Cause: The series ticker may be incorrect or have no open markets
Solution: Call get_series_list() to discover available tickers, or check references/series-tickers.md
Error: Football/soccer markets not found when searching "Football"
Cause: On Kalshi, "Football" refers to NFL — soccer uses league-specific codes
Solution: Use sport='epl', sport='ucl', sport='laliga', etc. for soccer leagues
