A Robinhood custom combo can be closed before settlement only if the closing trade fills. You cannot cash out one winning leg and leave the others running, because the selections trade together as one contract.
Robinhood’s support article on event contracts says you cannot open or close individual legs. That matters when the first result goes your way. It may raise the value of what remains, but it does not pay out that leg separately.
The whole combo needs a buyer
To close, you open Your positions, select the combo and choose Close position. Robinhood says opening or closing a combo needs both an exchange quote and a participant willing to take the other side, and that closing may be unavailable if nobody will. Combo orders use fill-or-kill, which means the entire order fills or it cancels. A close can therefore fail even though you can see the position in your account.
Picture a three-selection combo where the first event has won. The other two can still lose, so a buyer prices that remaining risk. They are not obliged to hand back your stake because one selection came in. A rising displayed value is also no guarantee of an exit at that value, so read the actual closing quote and check the final order status.
Canceling and closing do different jobs
Robinhood’s canceling and closing guide says a pending order can be canceled, but once an order fills it cannot be, even if it was an accident. Event contract trades are final once executed. Closing a position is a new trade at the available price, and if the market is closed or no buyer is available, you hold until expiration, when a correct contract pays $1 and an incorrect one pays $0.
The same guide warns that the app may let you submit certain custom combos with conflicting selections. Once filled, the order is final, so check the outcomes on the order review rather than relying on the app to catch a mistake.
What an early sale leaves you
Here is an arithmetic example, not a Robinhood fee schedule or a live quote. You pay $30 for a position plus $1 in opening fees, for a $31 cost. A buyer later offers $38 and a $1 closing fee applies. You receive $37, a $6 gain on the $31.
If you hold instead, the combo follows its settlement rules. Comparing a certain sale with the full payout, while ignoring the chance of losing the remaining selections, gives a false picture. Before you open a combo, decide whether you are willing to hold it if closing is unavailable. A position that only works if you can sell midway is a poor fit for an exit that depends on another trader.
