Search Behavior

Search uses a multi-strategy approach:

1. Direct ticker lookup — tries the query as a market ticker, event ticker (KX prefix), or series ticker
2. Series matching — dynamically searches all Kalshi series by title, category, and tags (e.g. "soccer" matches series tagged "Soccer")

• If many series match, shows an interactive numbered list — enter a number to drill into that series' markets
• If few series match, fetches and displays markets directly

1. Market title search — falls back to searching open market titles/tickers

Common sport/category aliases are expanded automatically (e.g. "nfl" also searches "football").

Interactive Series Lists

Both kalshi search and kalshi series display numbered tables when listing series. After the table, you're prompted:

Enter # to drill down (or q to quit):

Pick a number to load that series' open markets inline. The prompt loops so you can explore multiple series without re-running the command.

Trading

# Buy 10 YES contracts at 68c each
kalshi buy KXSB-26 10 68

# Buy NO contracts
kalshi buy KXWO-GOLD-26-NOR 5 32 --side no

# Sell (same syntax)
kalshi sell KXWO-GOLD-26-NOR 5 40 --side no

# Skip confirmation prompt
kalshi buy KXSB-26 10 68 --force

# Cancel an open order
kalshi cancel <order-id>

Notes

• Prices are in cents (68 = $0.68 = 68% implied probability)
• Prices display as both dollars and percentages (e.g. $0.68 (68%))
• --side defaults to yes if not specified
• buy and sell show a cost/proceeds summary and ask for confirmation (bypass with --force)
• --min-odds / -m filters out markets where either side's bid is below a percentage threshold (default 0.5%)
• --expiring / -e sorts results by soonest expiry, adds an "Expires" column, and excludes already-expired entries
• Expiry times are human-readable: "8h 35m", "Fri 04:00PM", "Apr 01", "Jan 01, 2027"
• Event tickers start with KX (e.g. KXWO-GOLD-26); market tickers have more segments (e.g. KXWO-GOLD-26-NOR)
• Market tables show outcome names (e.g. "Norway" instead of raw tickers) when available
