Introduction
# Kalshi Prediction Markets
Read-only integration with Kalshi's prediction market API.
## Capabilities
- **Browse markets**: List active events and markets by category - **Market analysis**: Get prices, volumes, orderbook depth - **Portfolio view**: Check positions and P&L (requires API key) - **Trade recommendations**: Find high-certainty, high-payoff opportunities
## Setup
Install dependencies: ```bash pip install requests cryptography ```
For portfolio access (RSA key signing required):
1. Go to [kalshi.com/account/profile](https://kalshi.com/account/profile) 2. Create new API key → save the **Key ID** and download the **private key** 3. Store credentials:
```bash mkdir -p ~/.kalshi mv ~/Downloads/your-key-file.txt ~/.kalshi/private_key.pem chmod 600 ~/.kalshi/private_key.pem ```
4. Create `~/.kalshi/credentials.json`: ```json { "api_key_id": "your-key-id-here", "private_key_path": "~/.kalshi/private_key.pem" } ```
Or run interactive setup: ```bash python scripts/kalshi_portfolio.py setup ```
## Scripts
### Market Data (No Auth Required)
```bash # List trending markets python scripts/kalshi_markets.py trending
# Search markets by query python scripts/kalshi_markets.py search "bitcoin"
# Get specific market details python scripts/kalshi_markets.py market TICKER
# Find high-value opportunities python scripts/kalshi_markets.py opportunities ```
### Portfolio (Auth Required)
```bash # View positions python scripts/kalshi_portfolio.py positions
# View balance python scripts/kalshi_portfolio.py balance
# Trade history python scripts/kalshi_portfolio.py history ```
## Opportunity Analysis
The `opportunities` command identifies markets where: - **High certainty**: Price ≥85¢ YES or ≤15¢ YES (implies 85%+ confidence) - **Meaningful payoff**: Potential return ≥10% on capital - **Sufficient liquidity**: Orderbook depth supports reasonable position size
Formula: `expected_value = probability * payoff - (1 - probability) * cost`
A good opportunity has: `EV / cost > 0.1` (10%+ expected return)
## Categories
