DraftKings - Can I edit the payout structure of a Fantasy Sports contest I created after it has been posted?

Editing of a contest's size or payout structure, once the contest has been created, isn't permitted. Learn more about contest creation.
If not all slots are filled when your contest starts, it may automatically resize based on settings, allowing it to run with fewer entries than initially intended.
Resized contests aim to maintain the original payout structure, opting for the closest alternative if the initial one is unavailable.
Learn more about contest resizing rules.

Only private contests of 200 entries or fewer can be resized.
The option for a contest to be auto-resized will be available in the Create a Contest flow.
If a reccurring contest can't be resized and isn't filled within 2 weeks, it will be canceled.
Recurring contests’ settings will be based on the original contest’s settings.
