On Investment Bets, portfolios are scored on percentage return rather than dollar gains. To keep everyone on the same footing regardless of account size, every bet is allocated an identical share of portfolio capacity: exactly 10%.
How slots and exposure work
Opening a bet commits one 10% slot from your available exposure capacity. By default an account has ten slots, which represents 100% total exposure when fully utilized. Each bet contributes its own percentage result directly to your score, and the leaderboard adds those results up. A bet's weight in your total score does not depend on how many other bets are open.
When slots are returned
A slot remains committed for as long as the position stays open. When a bet closes — either because you close it manually or because it reaches its target date and settles — that slot is released back to your available capacity, allowing a new bet to be opened.
What this means for active bets
If every slot is occupied, your portfolio has reached full capacity. In that state, a new bet can only be opened once one of your active positions closes — or, on a paid plan, by adding slots.
