Why we never chase losses (and how to stop)

Every bettor has lost a bet they were sure about and felt the urge to get it back straight away. Bigger stake, next match, whatever is on. That urge is called chasing, and in all my years around betting it is the most reliable way I know to turn a bad afternoon into a bad month. Here is why we never do it, what the maths says, and what to do if you catch yourself at it.

What chasing looks like

Chasing is rarely one dramatic decision. It is a handful of small ones:

• Raising your stake after a loss to "get level".
• Betting on a league, sport or market you would normally ignore, because it is the next thing on.
• Moving money into your betting account that was meant for something else.
• Betting in-play late at night because the day's result still stings.
• Telling yourself this next bet is different, when the only thing that has changed is how you feel.

If any of those sound familiar, you are not unusual. The question is what you do next.

Why chasing fails: the maths

The classic chasing system is doubling your stake after every loss, sometimes called the martingale. At even money, one win recovers all the losses plus your original stake's worth of profit. It feels bulletproof. It isn't.

Start at 1 unit, which is 1% of your bank, and double after each loss:

By the seventh bet you need 127 units, more than your entire bank, to chase a profit of 1 unit. Six losses in a row have already cost you 63% of it.

How likely is that? Even on a genuine 50/50 bet at fair odds, which no bookmaker offers, the chance of seven straight losses in any particular sequence is 1 in 128. Rare on a given day. Not rare over a season. Over 500 even-money bets, the chance of hitting at least one run of seven losses somewhere is about 86%.

And doubling does not change your expected return at all. If each bet loses a few pence per pound on average, so does the whole system. What chasing changes is the shape of your results: lots of small wins, then one loss big enough to wipe them out and more.

Chasing does not change the odds of the next bet. It only changes how much that bet can hurt you.

Why we never chase, even with an edge

Our stakes are set before a match by the confidence grade, from 0.25 units to 3 units. They do not move because yesterday went badly, and they do not move because yesterday went well.

That matters because losing runs are normal, even for a bettor who is doing everything right. A bettor who wins 55% of the time still has roughly a 37% chance of losing eight in a row at some point over 500 bets. We cover that in detail in bankroll management for casual bettors. If you raise stakes every time one of those runs begins, you are betting biggest at exactly the moment your bank is smallest.

We also record every tip on the Results page at the odds and stakes we published. Our record begins with the relaunch on 15 September 2026, so it is new and will build as tips settle. Losing runs will show up there, and we will not change our staking to hide them.

How to stop chasing

Willpower on its own is a weak defence at 11pm after a late goal. Rules made in advance work better.

Decide your limits before you bet

Set a betting bank you can afford to lose, a fixed unit size, and a maximum you will stake in a day or a week. Write them down. If you hit the limit, the day is over.

Use a stop rule

A simple one: after a set number of losing bets in a day, or a set loss in units, you stop until tomorrow. It does not matter much what the number is. It matters that you picked it while calm.

Never top up the bank mid-session

If your betting bank is empty, it stays empty until your next planned date, and you think hard about whether to refill it at all.

Put distance between you and the app

Log out, delete the app from your phone for a week, or turn off notifications. Use the deposit limit and time-out tools in your betting accounts where they are offered. A little friction goes a long way.

Keep a record

Write down every bet, including stake and result. Chasing thrives on a vague sense of being "nearly level". A written total is harder to argue with.

Free, confidential support in Great Britain

These services are free. You can use them for your own gambling or if you are worried about someone else's.

National Gambling Helpline (GamCare)

If you live in England or Scotland, call the National Gambling Helpline on 0808 8020 133. It is run by GamCare, and it is free, confidential and open 24 hours a day, every day of the year. You can also use live chat or WhatsApp instead of calling. Details are on GambleAware's get help now page, which also has a postcode search for local support.

NHS Wales helpline

If you live in Wales, GambleAware lists the free NHS Wales helpline on 0808 2819 265, available 24 hours a day, 7 days a week.

GAMSTOP self-exclusion

GAMSTOP is a free service that blocks you from signing up for or using online accounts with gambling companies licensed in Great Britain. You choose how long the block lasts, from 6 months up to 5 years, and you can set it to renew automatically. Once registered, you cannot cancel during the exclusion period, and the block stays in place after the period ends unless you contact GAMSTOP to remove it.

GAMSTOP also runs a separate scheme for high street betting shops, and points to bank gambling blocks and blocking software as extra layers. The Gambling Commission's page on self-exclusion schemes lists the free options for online gambling, betting shops and other venues.

If you are outside Great Britain, GambleAware's help page links to international support.

Betting should be something you do with spare money, for entertainment, at 18 or over. The moment it stops being that, stopping is the winning move. See our responsible gambling page for more on betting safely.
