If there’s an arbitrage opportunity, at least one line is incorrect. One (or both) of the books will be forced to move their line since so many people are betting it. This means you will end up beating the closing line. Your account will get flagged if a certain % of your bets are beating the closing line.
During events like March Madness, are sportsbooks focused on college basketball in a way that makes their lines on other sports less accurate because their attention is elsewhere or is it all quant stuff that runs automatically?
Ya, this. When trying to churn for promos/free bets I now basically wait until a few minutes before the game starts to make sure I don’t beat the closing lines. Its worth losing a few extra bucks betting a worse line to prevent being promo banned or limited imo.
Still lots of money out there but def is drying up compared to months past let alone years.
If a bettor is only betting in situations that are guaranteed to be profitable for them, in the long run they’re likely to be a net winner at all sportsbooks. Unless you’re incredibly confident that your lines are that good, you don’t want this type of player betting with you as a sportsbook.
But aren’t people who are arbing are also making other bets too most of the time? Is it just assumed that an arber is +EV and you need to shut him down.
Haralabob was on a pod recently and it was the best one he’s ever done imo. He gets into fun stuff about his betting life after the first ~15 min of standard intro/stuff you’ve already heard. Highly recommend.
