Kalshi Trading System

Two trading bots sharing one execution engine. Ran for about a month, switched off April 2026.

Numbers

• 820+ markets traded live
• 12,775 markets backtested, plus a 10,000-path Monte Carlo
• $20 to $500 in the first week, on deliberately tiny stakes

The bet

• A handful of Kalshi accounts consistently move markets
• When they agree on a direction, follow them

What it did

• Whale consensus bot: took the side the biggest traders agreed on
• Crypto binaries bot: traded crypto yes/no contracts on its own signal
• Shared execution engine: both bots ordered through one code path
• Risk: fractional Kelly sizing, circuit breakers, kill switch at 40% drawdown
• Telegram control: every fill and signal on my phone, one message to shut it all down
