Is sports betting rigged?
No, sports betting is not rigged, but it is against your favor because of the vig.
In order to make money, sports betting companies collect a commission on losing bets, which is called the vig. Because of that, it may seem like sports betting is rigged, but that's simply to insure it's a source of revenue. If sports betting didn't make a profit, there would be no reason to legalize it across the country.
For sports betting to exist, companies have to make money off it, which is why PASPA was struck down in 2018. While Nevada has been raking in millions of dollars through sports betting, new legislation will allow each start to benefit from sports gambling. If states are benefitting from sports betting, that means those wagering are losing money more often than not.
If you're losing because you think "sports betting is rigged" and can't get out of the game, there are resources to help. There are online guides, readily available access to addiction centers and a National Problem Gambling Helpline.
