Kalshi prediction markets

Arka includes a kalshi skill for read-only Kalshi prediction market data: search open markets, inspect a ticker, see trending contracts by 24h volume, and check exchange status. No trading — quotes and discovery only.

Quick examples

kalshi search bitcoin
kalshi market KXBTC-25JUL-T100K
kalshi trending
kalshi status

Natural language also works:

arka "kalshi predictions on bitcoin"
arka "what are kalshi odds for inflation"
arka "kalshi trending"

Commands

Command	Description
`kalshi search <keywords>`	Search open markets by title/ticker keyword
`kalshi market <TICKER>`	Full quote for one market (YES/NO, volume, close time)
`kalshi trending`	Top open markets by 24h volume
`kalshi status`	Kalshi exchange/trading status

API approach

The skill uses Kalshi’s public Trade API v2 (no API key required for read-only market data):

Base URL: https://external-api.kalshi.com/trade-api/v2
Endpoints: GET /markets, GET /markets/{ticker}, GET /exchange/status

Kalshi has no dedicated keyword search endpoint, so kalshi search fetches open markets and filters client-side by keyword.

Optional configuration

Add to ~/.config/arka/.env only if you need a custom base URL or future authenticated endpoints:

# Optional — public read endpoints work without a key
KALSHI_API_KEY=
KALSHI_API_BASE=https://external-api.kalshi.com/trade-api/v2

Skill	Example
`stock`	`arka stock news`
`currency_convert`	`arka convert 100 USD to INR`
`predictions`	`predictions --domain stocks --deep "banking sector"`
