Contracts have been allocated based on the value of bids that were submitted. Teams that participated may now find their portfolio is currently worth less than its starting value.
This isn’t necessarily a cause for concern because the leaderboard positions are based on “mark-to-market” prices. For example, if you paid 0.20 for a contract that has an 80% chance of paying out 1.00 then you got a bargain. If the opening price of that contract is only 0.10 it will look as if you have lost credits. But if you hold the contract to settlement, or at least until other participants realise how underpriced it is, the value of your portfolio and leaderboard position will improve accordingly.
The only leaderboard that really matters is the one after all markets have settled.
