Can sportsbooks void a winning bet after the match is over?

[Fortify]

I was reading through some sportsbook rules regarding "Palpable Errors" and something seems a bit unfair.

If a bettor enters the wrong stake or clicks the wrong team by mistake, customer support will simply tell you: "All bets are final once confirmed."

Yet many sportsbooks reserve the right to cancel bets even after the event has finished if they claim the odds were incorrect.

I understand if someone gets odds of 20.0 instead of 2.00. That's obviously a mistake.

But what happens when the odds are just slightly off the market — say 2.20 instead of 1.95? Different sportsbooks offer different odds all the time.

And more importantly, has anyone ever seen a bookmaker void a "palpable error" bet that ended up losing? Or does the mistake only get noticed when the player wins?

Have you ever had a settled, winning bet cancelled retroactively under this rule?

It's a very rare situation, but with the example you've given 2.20 versus 1.95 it's quite possible that a bookmaker would not bother correcting their mistake because the losses are minimal and it's not worth the potential legal trouble or bad feeling by their customers if they were to retrospectively take money back. If a bookmaker is making money from a customer almost every day, it's just bad business sense to annoy them over fairly trivial amounts. What this clause is meant to cover is massive discrepancies or major miscalculations like you describe, they absolutely would void bets if 20 was mistyped when it should have been 2. They have a slight defense and it is similar to retailers who make big pricing errors online which get abused - they then cancel orders on the basis that a customer should have known it was a pricing error which is covered by terms and even the law in many countries. The only similar experience I've had is the US election after Trumps first term where he continued to dispute losing and would not concede, which caused the bet to hang for many weeks, but eventually settled.

With such little odd difference, that is not a mistake but a odd difference from other betting site. If it is a mistake, that is the expected value bet that some bettors are looking for. If won, there is nothing the betting site can do. The odd difference from other bookies is very little and not what will affect the bookie in any way if it is a reputed bookie.

it does not fall under palpable errors, as a palpable error means an obvious mistake, so if the odds are just a little different it should not count since differences do exist, especially since not all bookies have the same odds in the market, that's why arbitrage betting exists.

However if you are a regular gambler you would notice if it's an obvious mistake or not, like if the odds are supposed to be 2x and they offer 10x, that is an obvious mistake, but if you still take it then it's not against the rules, though they should refund the bet whether it wins or loses. That's a fair casino for me.


These 2 casinos though have paid gamblers despite mistakes on odds.

• FanDuel – Paid $82,610 despite incorrect odds (2018)
• BetMGM – Paid $214,000 despite an odds error (2023)

Yea, if they are able to refund the bet wether it wins or loses, then it's okay and acceptable. Where I won't take it or see it as unfair is when it only counts if the bet wins, and if the bet losses, they say no need, that the bet lost after all. Thats gonna be a bit unfair.

Some are clearly mistakes as you pointed, and that king is understandable. After all, we are humans, and mistakes are inevitable. But to avoid such ugly cases coming up, gambling sites should be very careful to avoid such awful mistakes, because it doesn't make any sense that someone wins a bet, and they are refusing to pay out the exact amount won due to some unacceptable mistakes by the bookies.

I think it would be ideal of the sport book also took part of the responsibility when comes to errors like those. Instead of refunding all the money of withholding it, they should allow the gambler to keep a percentage of the money as a way to apologize with all the inconvenience.
You know, the whole point of the casino and bookie is keep people coming so they can continue to win money. The moment the bookie starts to disrespect and mistreat their bettors, it is the beginning of the end of the service.

Thankfully, it has never happened to me, but I know it is rather a fairly common occurrence on some bookies, to have one's bet cancelled because of some allegedled mistake by either the bookie or the odds provider.

In most cases they never took responsibility just because they are controlling accounts and all funds of customers; they did as they wanted in crypto. There are enough cases where they freeze accounts, and customers also face other problems due to not having central authority, which can help them get things back to normal.

I read many posts on social media about these cases, while customer bets were voided as sportsbooks were not feeling good and had losses, and they were thinking they had enough power to stop.

Now one sportsbook is already closed; they did the same to me, and I was not able to do anything because they restricted my account, and then I have to withdraw my funds without having winnings in things like these mostly fiat sportsbooks have better solutions, or once a bet is confirmed, they never void it due to having any problem.

Unilateral conditions within the sphere of betting can seriously disrupt you in case your rights as a gambler are infringed upon. The return policy of bets must apply equally to cases when you have either won or lost in a particular round. Betting house which will deny you payments solely in case you guessed right proves to provide extremely poor customer service. Mistakes made by technicians are quite normal but the betting management must minimize the negligence. Your effort and analysis cannot go to waste because of some technical difficulties attributed purely to your fault. It is essential for the bookmaker to be strict in their service accuracy so as to guarantee that each round favors you.

Happened to me in some bookies that are also known in the forum.
I don't know what actual reasons why these void bets are happening when I've seen the games played properly without any problems until the end.
Although odds are usually slightly different from each bookie but I think changing that at the end is due to the demand and situation of the game if it's live.
But once bets are finally confirmed and casted, it should remain intact for how much odds we've bet for.
I have no grievance to these changes and voidance because there are also incidents that my bets should lose but they have cancelled it. In my experience, it's just fair.

Have you ever had a settled, winning bet cancelled retroactively under this rule?

All those rules are to protect the business of individual casinos so that if error happens and a player was giving high odds instead of a moderate odds, they have the right to cancel the game or reduce the odds automatically even after the game has ended.
What I see there is an ordinary protection in time of system bug giving out large odds due to system malfunctioning.
This is why casinos has more edge than their players and there is nothing that can be done about that.

If I could remembered correctly similar thing has happened to me before back then, I remembered placing bet and at the last I didn't end up winning the bet, it was withhold for around weeks before they confirmed it that the game was cancelled and after a while the funds was refunded back to me because the game was cancelled.
When we talks about odds changes, sometimes when the casino allocates a higher odds and the game happens to play they could deduct it from the winning and refund back the initial odds to the gambler. For instance: if the total was around 3, and it happens that the real odds was around 2.0 or 2.5 odds you would see the casino payment only for 2.5 odds and whatever calculation that was done with 3.0 odds would never be credited.

No, it is no possible to reverse or cancel a bet that had been played.
I mean if the event has come and gone.
But at some points, the bookies intercepts players results with that excuse of system glitch that is being wrongly uploaded the odds wrongly.

Such occurrence is also not new as there had been several confirmed gamblers that had been lucky enough to hit the jackpots but excuses arise from the bookie of their own wrongs while punishes the players by canceling the bet or giving them conditions that is to only pay them part of the total payouts.
The dealer in the casinos and the bookie in the sportbooks has not been transparent enough which is why it is also important consideration reputation of the company before you can play with them.

There is no leeway for any player's accidental click, but player's winning could be taken back due to operator's error.

Yes, I have heard of such incident several time.

In Illinois, BetMGM voided several $500 bet due to incorrect odds. State gaming board rules in favor of operator.

Actually, the rule is not entirely unfair. If operator are not protected in event of genuine mistake then any single error could cause them significant harm. And some professional bettors deliberately look for incorrect odds.

I think this rule is mostly about more about a one sided option that’s often used by the house when the result is already known and probably not in their favour. A player is just about to be paid some good amounts from a winning bet, at this point, the casino would try to look at some loopholes that would give them the legal ground not to actually pay that amount to the player, and it’s less about actually correcting genuine mistakes but just a tool to turn the table in their favor.
That’s why you barely see a sportsbook void a palpable error that have already lost, they’ll simply just keep the stake and the result would still stand.

Still, bookies in general are aware they are not supposed to abuse their legal advantage when comes to settling bets in the favor. Bettors are not stupid and people talk about their negative experiences both on the internet and also in real life.
If they abuse their terms of service they could eventually end up with no bettors and no volume on their platform.
Big bookies, have enough liquidity and volume for them to make millions of dollars and they are not willing to sacrifice such huge amount of income for the sake of a single money-saving move against a single bettor who happened to be right.

Reputation matters in this industry.

Casinos are always ready to use system malfunctioning as an excuse to avoid paying for big odds but would they have given you back your money if you mistakenly bet a higher amount than you would have wanted to bet. When it happens to them we can not tell if they are lying or not, they will automatically reduced your payout but for our own mistake, our money is gone.

This is not a fair rule to gamvlers because most times it is those high odds that attracts us to bet on the games then what happens if we lose our money but the odds was a glitch, we do not get refunded hence the casinos should not have an escape option from paying when we win or at least the gambler should be compensated rather than just automatically reducing the payout or cancelling the game entirely as that is not fair to we gamblers.

Maybe they have a certain threshold for odds differences caused by system errors. I believe that kind of situation actually happens every day. We may have placed bets at incorrect odds, we just didn't realize it, and the sportsbook just let winning bets pay out at those incorrect odds. I am sure they don't want to risk their platform's reputation by disallowing winnings from small odds differences.

I personally have never experienced (or realized) that kind of situation. My bets were cancelled a few times, but only for the same reasons, matches being cancelled or postponed. Voiding bets because of incorrect odds is just normal for me, it still makes sense. But for gamblers who are opportunists and often calculate odds, it may affect their bankroll badly. In this case, I think sportsbooks should give compensation to winners whose bets were voided due to incorrect odds. For example, they can convert the "winnings" into free bets or something else.
