To my knowledge, if you are in the USA your options for the fastest payouts are with:
5Dimes - has methods of payment in less than 24 hours and you can cash out up to $9,000 per transaction
Bovada - has a method of payment (called "Rapid Transfer") which sends your money (up to $800 per transaction) in less than 24 hours
If you are located outside of the USA, then your options for getting paid in less than 24 hours are much wider, I will just enumerate a few:
Pinnacle - payments under $10,000 are released in less than 10 minutes and over $10,000 (up to no max) in just a few hours (under 24)
BetAt-Casino - pays in less than 4 business hours (up to €8,000 per day) starting with your second withdrawal
Betfair - no maximum payout limits and pays in less than 24 hours
BETDAQ (same company as
Ladbrokes) - no maximum payout limits and pays in less than 24 hours
Ladbrokes - pays up to €37,500 per transaction within 6 to 24 hours
Bet365 - pays up to £20,000 per transaction in less than 24 hours
32 Red Casino (and all casinos in its group:
Dash Casino;
Golden Lounge;
Nedplay) - pays up to $10,000/€5,000 in less than 24 hours
*Please note that those time frames refers mostly to web-wallets transactions, as these are the fastest options.
For bank transfers it is normal to take up to 5 business days for the transfer to complete once the money was released.
**Also, there are more websites which usually pays in 24 hours, but since their terms mention it can take up to more days, I have not mentioned them here in my above list. Also, this is not a very comprehensive list, do your own research and you will probably find more.
