Liquidation on Kalshi Perpetuals
Liquidation is the risk that defines leveraged trading, and the one new perpetuals traders most underestimate. It is not a fee or a penalty; it is the exchange closing your position to stop your losses from going further. When it happens, you can lose the collateral behind that trade.
Here is how it works and, more importantly, how to avoid it. This is educational, not financial advice.
What liquidation is
Every leveraged position has a maintenance margin: a minimum balance you must keep to hold it. As a position loses value, your margin shrinks. When it falls below the maintenance threshold, Kalshi automatically closes the position to prevent further losses. That forced close is liquidation, and the collateral supporting the trade can be lost in the process.
Why leverage brings it closer
The more leverage you use, the smaller the price move needed to wipe out your margin. At high leverage, a move of just a few percent in the underlying can be enough to liquidate you. In volatile crypto markets, moves like that happen routinely, which is why high leverage and liquidation go hand in hand.
How to avoid it
The defenses are straightforward and worth taking seriously. Use less leverage than you think you can handle, which keeps your liquidation price far from the current price. Keep a margin buffer well above the maintenance requirement. Use stop-loss orders to close on your own terms before the exchange does it for you. And monitor open positions, especially around volatile events.
Respect the mechanism
Liquidation is not a rare disaster; at high leverage it is the base-case outcome of a normal market move. The traders who last are the ones who size positions so that an ordinary swing never threatens their margin. If a realistic move in the asset would liquidate you, your position is too large.
