Installation

macOS / Linux (Homebrew)

brew install 6missedcalls/tap/kalshi-cli

Go Install (requires Go 1.25+)

go install github.com/6missedcalls/kalshi-cli/cmd/kalshi-cli@latest

Build from Source

git clone https://github.com/6missedcalls/kalshi-cli.git
cd kalshi-cli
go build -o kalshi-cli ./cmd/kalshi-cli

Authentication

Interactive Login (Recommended first time)

kalshi-cli auth login

Follow the prompts to:

1. Copy the displayed public key
2. Add it to your Kalshi account at https://kalshi.com/account/api-keys
3. Enter the API Key ID when prompted

Credentials are stored securely in your OS keyring (macOS Keychain, GNOME Keyring, or Windows Credential Manager).

Non-Interactive Login (Bots / CI)

# Via flags
kalshi-cli auth login --api-key-id YOUR_KEY_ID --private-key-file /path/to/key.pem

# Via PEM content
kalshi-cli auth login --api-key-id YOUR_KEY_ID --private-key "$(cat /path/to/key.pem)"

# Via environment variables
export KALSHI_API_KEY_ID=your-key-id
export KALSHI_PRIVATE_KEY="$(cat /path/to/key.pem)"
kalshi-cli auth login

Config File

Add to ~/.kalshi/config.yaml:

api_key_id: your-key-id
private_key_path: /path/to/key.pem

Credentials are resolved in order: config file, environment variables, OS keyring.

Demo vs Production

	Demo (default)	Production
Flag	(default)	--prod
API	demo-api.kalshi.co	api.elections.kalshi.com
Money	Fake/test	Real USD

The CLI defaults to demo mode. You must pass --prod to trade with real money. This is a safety feature.

Overview

You are an expert in using kalshi-cli for prediction market trading on Kalshi. Your goal is to help users trade event contracts efficiently while emphasizing safety and risk awareness.

How to Use This Skill

1. Safety First: The CLI defaults to demo mode. Only use --prod when the user explicitly wants real trading.
2. Verify Before Trading: Always show the exact command and confirm with the user before executing trades.
3. Check Prerequisites: Confirm auth is set up (auth status), exchange is active (exchange status), and sufficient balance exists.
4. Use JSON Output: For scripting and automation, use --json for machine-readable output.
5. Understand Tickers: Markets use structured tickers like KXBTC-26FEB12-B97000. Events group related markets.

When to Use This Skill

Use this skill when the user wants to:

• Browse or search prediction markets (politics, crypto, sports, economics, weather)
• Place bets (limit orders, market orders) on event contracts
• Check market prices, spreads, and order books
• View ASCII candlestick charts
• Stream live price updates via WebSocket
• View or manage open orders
• Check portfolio positions and P/L
• Cancel or amend orders
• Monitor trade fills and settlements
• Use batch orders for market-making strategies

Common trigger phrases:

• "What prediction markets are open on Kalshi?"
• "Buy YES on Bitcoin above 100k"
• "Show me the order book"
• "Stream live prices for this market"
• "Show me a candlestick chart"
• "Cancel all my orders"
• "Check my positions"
• "Place a limit order at 50 cents"
• "What's my balance?"

When NOT to use this skill:

• User wants to trade stocks/ETFs/options (use Alpaca trading skill)
• User wants to trade on Polymarket (use Polymarket trading skill)
• User wants financial advice (provide tools, not recommendations)

Key Concepts

Tickers

Markets use structured tickers: KXBTC-26FEB12-B97000

• KXBTC = series (Bitcoin)
• 26FEB12 = date (Feb 12, 2026)
• B97000 = strike ($97,000)

Events vs Markets

An event groups related markets. For example, "Bitcoin price on Feb 12" is an event containing markets at different strike prices ($90K, $95K, $100K, etc.).

Contracts

Kalshi trades event contracts priced 1-99 cents, settling to $1 or $0. All values are in cents.

Subaccounts

Up to 32 subaccounts per user for multi-strategy isolation.

Order Groups

Cap total fills across multiple orders — useful for market-making where you don't want both sides filled.

Global Flags

Every command accepts these flags:

Flag	Short	Default	Description
--json		false	Output as JSON for scripts
--plain		false	Plain text for piping
--yes	-y	false	Skip all confirmation prompts
--prod		false	Use production API (real money)
--verbose	-v	false	Debug output
--config		~/.kalshi/config.yaml	Config file path

# Or set globally
export KALSHI_API_PRODUCTION=true

Best Practices

Safety

1. Demo first — the CLI defaults to demo mode. Test everything before going live.
2. Confirm before --prod — always verify with kalshi-cli auth status before trading real money.
3. Use --yes carefully — it skips all confirmations. Only use in tested bot scripts.
4. Set position limits — use order groups to cap maximum exposure.
5. Monitor positions — use kalshi-cli watch positions for real-time tracking.

Order Management

1. Prefer limit orders — better price control, lower fees.
2. Use order groups for market-making — prevents both sides from filling simultaneously.
3. Amend instead of cancel/replace — native orders amend is atomic and faster.
4. Batch when possible — use orders batch-create with a JSON file for multiple orders.
5. Check queue position — use orders queue to see where your resting order sits.

Bot Development

1. Use --json --yes — machine-parseable output, no interactive prompts.
2. Check exit codes — 0=success, 2=auth error, 4=API error, 5=network error.
3. Handle rate limits — Basic: 10 writes/sec, 20 reads/sec. Apply for higher tiers if needed.
4. Use WebSocket for live data — watch ticker is more efficient than polling.
5. Store credentials securely — use env vars or keyring, never hardcode.

Important Notes

• All values in cents — prices are 1-99, balances are in cents ($100 = 10000 cents).
• Demo by default — use --prod flag for real trading.
• Tickers are structured — KXBTC-26FEB12-B97000 = series + date + strike.
• Events group markets — browse events to find related markets at different strike levels.
• Order groups cap total fills — essential for market-making strategies.
• Rate limits — Basic: 10 writes/sec, 20 reads/sec. Apply for higher tiers via Kalshi.
• RSA-PSS auth — private key never leaves your machine. No passwords, no sessions to manage.
• USD settlement — no crypto, no wallets, no gas fees.
• CFTC-regulated — fully legal in the United States.

Fees

Type	Formula	Max at 50/50
Taker	roundup(0.07 * C * P * (1-P))	1.75c/contract
Maker	roundup(0.0175 * C * P * (1-P))	~0.44c/contract
S&P/Nasdaq markets	Half the normal rate	~0.88c taker

Lower fees for orders near the extremes (close to 0 or 100). No settlement or withdrawal fees (ACH).

Troubleshooting

Not authenticated

kalshi-cli auth status  # check status
kalshi-cli auth login   # re-authenticate

Wrong environment (demo vs prod)

kalshi-cli auth status  # shows current environment
# Use --prod for production, omit for demo

Order rejected

• Check balance: kalshi-cli portfolio balance
• Verify market is open: kalshi-cli markets get TICKER
• Check exchange status: kalshi-cli exchange status
• Price must be 1-99 cents

Rate limited

• Basic tier: 10 writes/sec, 20 reads/sec
• Apply for Advanced/Premier tier at Kalshi for higher limits
• Use batch operations where possible
