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:
sports-skills kalshi search_markets --sport=nba
sports-skills kalshi get_todays_events --sport=nba
sports-skills kalshi get_sports_config
sports-skills kalshi get_markets --series_ticker=KXNBA --status=open
Python SDK (alternative):
from sports_skills import kalshi
kalshi.search_markets(sport='nba')
kalshi.search_markets(sport='nba', query='Lakers')
kalshi.get_todays_events(sport='nba')
kalshi.get_sports_config()
kalshi.get_markets(series_ticker="KXNBA", status="open")
CRITICAL: Before Any Query
CRITICAL: Before calling any market endpoint, verify:
- The
sportparameter is always passed tosearchmarketsandgettodays_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:
WRONG: search_markets(query="Leeds") → 0 results
RIGHT: search_markets(sport='epl', query='Leeds') → returns all Leeds markets
Important Notes
- On Kalshi, "Football" = NFL. For football/soccer (EPL, La Liga, etc.), use sport codes:
epl,ucl,laliga,bundesliga,seriea,ligue1,mls,worldcup. - 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:
searchmarkets(sport=...),gettodaysevents(sport=...), andgetsports_config()work the same way on both platforms.
Workflows
Sport Market Search (Recommended)
search_markets --sport=nba— finds all open NBA markets.- Optionally add
--query="Lakers"to filter by keyword. - Results include yesbid, nobid, volume for each market.
Today's Events
gettodaysevents --sport=nba— open events with nested markets.- Present events with prices (price = implied probability, 0-100 scale).
Futures Market Check
getmarkets --seriesticker=<ticker> --status=open- Sort by
last_pricedescending. - Present top contenders with probability and volume.
Market Price History
- Get market ticker from
search_markets --sport=nba. getmarketcandlesticks --seriesticker=<s> --ticker=<t> --startts=<start> --endts=<end> --periodinterval=60- Present OHLC with volume.

Troubleshooting
Error: searchmarkets 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 searchmarkets. 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 getserieslist() 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
