Kalshi variant 001 led the family with -5.80% ROI. The weakest completed variant

Starter is $19/month with 10 deploys per week. Upgrade as you grow.

This strategy trades the Kalshi market on New York City's daily high temperature (KXHIGHNY). Every 45 seconds, it checks weather data from LaGuardia Airport and buys 'No' contracts if the current temperature is cooler than a forecast cap, provided the contract price is high enough. It limits total contracts held to 10 and exits when the price drops below 30 cents, the temperature rises to 72°F, losses reach $10, or 30 minutes before expiry.

A few notes on these numbers

Methodology: Backtests replay supported historical market data, usually a 30-day Studio window, and evaluate strategy rules on the available cadence. Signals can fill no earlier than the next tradable step. Taker fills use top-of-book prices or available L2 depth, with Kalshi-style fees where modeled. Queue position, latency, and future liquidity are not fully modeled. Simulated P&L is net of modeled fees over the window.
Starting capital: Kalshi backtests use the strategy's configured max position as the risk-capital denominator. Return is computed from that configured capital, while total P&L is still shown in dollars.
Past performance: Backtested results are hypothetical. They are derived from historical data and do not reflect live execution risks like slippage beyond the orderbook, partial fills, API latency, or venue outages. Past performance does not guarantee future results.
Not financial advice: Nothing on this page is investment, legal, or tax advice. Prediction markets carry real risk of loss. Only trade with money you can afford to lose, and do your own research before deploying any strategy live.
