Been trading on Kalshi for a while now, mostly smaller contracts, playing around with different event types like CPI or interest rate movements. I got pretty good at anticipating the general direction, maybe not the exact outcome, but good enough for a consistent, albeit small, profit.
The mistake came when I decided to scale up. Had a few decent wins in a row predicting whether S&P would close up or down on a given day. Felt like I had a handle on the market sentiment, maybe even an edge. So, naturally, I significantly increased my contract size on the next few trades. The market decided to throw a curveball right then. A couple of unexpected economic reports came out, causing whipsaws I hadn't factored in. My initial small profit evaporated, and I ended up giving back everything I'd made and then some.
It was a classic case of overconfidence leading to poor risk management. Just because you're good at predicting an outcome at a small scale doesn't mean your edge translates proportionally to larger sizing. The emotional aspect of having more capital on the line changes your decision-making. Now I'm back to smaller sizing, focusing on consistency and only scaling up very gradually, if at all, based on a much larger sample size of profitable trades at the current level. Respect the leverage, even if it's just event contracts.
