Understanding Position Sizing for Kalshi Contracts

Hey folks, wanted to touch on a concept that's absolutely crucial for longevity in any market, but particularly relevant for Kalshi's event contracts: position sizing. It's not about being right or wrong on a single contract, but about managing your capital over a series of trades. Simply put, position sizing is determining how much of your total trading capital you're willing to risk on any single contract or event.

Let's say you have a $1,000 account. A common rule of thumb is to risk no more than 1-2% of your capital on a single trade. So, if you're looking at a $NZDUSD contract on Kalshi and you're buying 'Yes' at $0.60, your maximum loss would be $0.60 per contract. If you limit your risk to $20 (2% of $1,000), you can afford to buy approximately 33 contracts ($20 / $0.60). This isn't about how much you can buy, but how much you should buy to protect your bankroll. It keeps you in the game longer, even through a string of losing calls, and allows your edge to play out over time. It's the bedrock of risk management.
