Kalshi system

Original strategy paused June 22, 2026. Beta in progress

Up 79.7%. Then the market changed.

An automated strategy across Kalshi event markets. When its best market went quiet and its sizing drifted, I switched it off instead of trading through it. This page is the rebuild, in public.

The original run, by the numbers

Return on capital risked+79.7%
Contracts won-lost384-83
Trades531
Currency win rate90.6%

Settled trades, March 17 to September 17, 2026. Return is on capital risked, not a balance.

After the June pause a smaller S&P book kept running into September: 62 trades for -9.0% on the same capital. It is not where the edge was, and it is included in the figures above.

How it went

  1. Early run

    Currency contracts carry the book

    Most of the edge, traded with tight position sizing.

  2. Late April

    Currency orders stop filling

    The best market drops out, and the rest of the strategy doesn't adjust.

  3. May to June

    Momentum regime, size drift

    Sustained momentum exposes the remaining trades, and positions grow past their limits.

  4. June 22

    Switched off

    Stopped to rebuild rather than trade through it.

The beta fixes each failure, one for one.

Read the regime

A filter that spots sustained momentum and stands aside.

Hard position caps

Sizing limits enforced in code, so they can't drift.
