How these bots work
Kalshi-native bots sign every request with an RSA private key, trade in cents, and can paper trade against a real demo exchange, which Polymarket does not offer. They are US-only in practice because the account is.
The category is smaller than Polymarket's. GitHub search for kalshi bot returns 894 repositories against 4,090 for polymarket bot as of 2026-09-08, and the top results are the same cross-venue projects. The purpose-built entries are a research-to-order CLI from OctagonAI, a weather-ensemble project, and a Telegram-fronted skeleton.
Kalshi's taker fee is quadratic in price, at most 1.75 cents per contract at 50 cents per DRADIS's README, so an edge threshold that ignores it is wrong by up to that much per contract.
How to choose
- Demo-environment support, with a single flag to switch: KALSHI_USE_DEMO or KALSHI_DEMO.
- Correct auth: key ID plus RSA-PSS signed requests. A README that lists only an API key string is out of date.
- Fee-aware edge math and maker versus taker awareness.
- Series-level market discovery (KXHIGH, KXBTC15M and so on) rather than hard-coded tickers that expire.
- Recent pushes. Kalshi ships API changes and series regularly.
