Best March Madness betting sites for 2025

Man, March Madness is almost here, and I’m already fired up. If you’re wondering when does March Madness start in 2025, it all kicks off with Selection Sunday on March 16, then the First Four on March 18, and the madness really begins with the first round on March 19. That first weekend? Pure chaos—and the best time to find some insane value on underdogs.

Last year, I hit one of my best bets ever. Threw some cash on a 14-seed upsetting a 3-seed, mostly for fun. Wasn’t even watching too closely—until the underdog started closing the gap. By the final two minutes, I was losing my mind. They actually pulled it off, and since I placed my bet on a book with better odds, my payout was way bigger than it would’ve been anywhere else. That’s when I realized—where you bet matters just as much as what you bet on.

Where I’m betting this year​


BetOnline – Best for underdog odds, especially if you like betting on lowest seed to win March Madness props.
Bovada – Best for early lines—great if you wanna lock in a number before the public jumps on it.
MyBookie – Best for bonuses & props—they’ve got creative bets and solid coverage for March Madness women’s games too.
Everygame – Best for fast payouts—because waiting days for your winnings is brutal.

My game plan for March Madness 2025​


March Madness is all about finding the right spots—one good bet can turn a small wager into a massive win. I’m already scanning this year’s bracket for a 12 or 13-seed that could pull off something crazy. Who’s got a sleeper pick this year?
 
I’ve had good experiences with DraftKings for March Madness. Their live betting options are top-notch, and they often release lines earlier than other books.
 
For those looking for generous bonuses, Caesars Sportsbook has some great offers during March Madness. Their profit boosts can really add value to your bets.
 
BetUS has been my go-to for March Madness. Their 100% sports welcome bonus is one of the best, and they always have solid odds on underdogs.

Same here. DraftKings also offers a variety of prop bets, which keeps things interesting throughout the tournament.
 
BetUS has been one of my favorite books for March Madness, especially for underdog plays. Their 125% sign-up bonus gives you a solid bankroll boost, and I’ve noticed they tend to offer slightly better moneyline odds on lower-seeded teams compared to some of the bigger books.

Another thing I like is their live betting setup—super smooth, and they update the lines quickly, so you can grab value before the market adjusts. Last year, I jumped on a 12-seed during halftime when they were only down by 5, and the second-half comeback cashed out big. If you’re looking for a solid mix of bonuses, underdog value, and live betting, BetUS is worth checking out.
