Tipster scams: sure tips, fixed matches and paid groups
Any offer of "sure tips" or "fixed matches" for money is a scam. Someone who really knew the result in advance would bet on it himself instead of selling it on a messaging app for a few hundred pounds. Scammers live off the fact that betting is extremely volatile: over a few dozen tips, luck is easily mistaken for skill. Below we describe the most common schemes, show with numbers why a short tipster record means nothing, and explain what to do if you have already lost money.
Key takeaways
- 1
Someone who really hit 90% of tips at odds of 1.50 would make £7,000 a month on his own from 20 bets of £1,000.
- 2
A hundred tips mean nothing: of 1,000 tipsters with no knowledge at all, about 28 will reach a yield of +20% or more by pure chance.
- 3
Doubling the stake from £20 at 2.00 wins just £20 when the sixth bet lands after £1,260 of stakes, and at a 5% margin such a six-bet cycle loses £6.44 on average.
- 4
A credible tipster publishes every tip before the match, somewhere he cannot edit, has several hundred of them and quotes his yield at odds you could actually get.
- 5
After a scam, stop paying, keep the evidence and report it to your bank and to Report Fraud, or in Scotland to Police Scotland on 101.
The most common tipster scams
Selling "fixed matches"
The message usually reads much the same: "we have information from inside the club", "the result is fixed", "odds of 20.00, pay and you get the tip". It is always a scam. Even if a match really were fixed, nobody would sell that knowledge to strangers online, because every extra large bet catches the attention of bookmakers and integrity monitoring systems. Match-fixing is a crime: in Great Britain, deception or interference in a sporting event that people bet on counts as cheating at gambling, an offence under section 42 of the Gambling Act 2005 that carries up to two years in prison. So the buyer gets neither a sure result nor any protection. Sellers of "fixed" virtual football results lie in the same way: every result there is drawn by a random number generator.
Paid groups with "bankers"
Groups on messaging apps and social media where a monthly subscription gets you "sure tips". The results are shown selectively: winning bets go up on the channel, losing ones disappear or are "voided". After a string of losses the group changes its name and starts again.
Fake bet slip screenshots
A screenshot of a winning bet slip is easy to doctor in an image editor. An even simpler trick is sending different tips to different people. An illustrative example: a scammer sends a 1X2 tip on a match to 810 people, a different result to each third of them. After one match, 270 people have seen a winner. He repeats this four times and ends up with 10 people who have seen 4 winning tips out of 4. Those ten are the ones he sells a "paid package" to.
The doubling "method"
It promises a risk-free profit: you bet at odds of 2.00 and double your stake after every loss until a bet finally comes in. Let's count it step by step with a starting stake of £20:
- You lose five times: 20 + 40 + 80 + 160 + 320 = £620.
- The sixth stake is £640.
- The bet wins: the return is 640 × 2.00 = £1,280.
- In total you have staked £1,260, so the win leaves you £20 up, exactly your first stake.
That is the whole trick: ever larger sums put at risk to win the same £20. Without a bookmaker's margin, at a true 50% chance, a cycle like this (at most six bets, with £1,260 behind it) wins £20 in 98.4% of cases and loses £1,260 in 1.6%, which averages out at exactly zero. Doubling creates no edge. It only swaps many small wins for a rare, large loss. A bookmaker's odds of 2.00 carry a margin, though: at 5% the chance behind them is about 47.6%, six losses in a row come up in 2.1% of cycles, and the average cycle loses £6.44.
On top of that, a run of five losses at a 50% chance turns up in about 81% of sequences of 100 bets, and a longer run quickly calls for stakes you do not have or the bookmaker will not accept: after ten losses the eleventh stake is £20,480, with £40,940 staked in the cycle, still to win £20. How bookmakers cap stakes and winnings is covered in our guide to maximum bet limits.
Bots and systems that "guarantee a profit"
Programs, apps or "AI algorithms" that are supposed to pick winning bets on their own. They usually cost a one-off fee or a subscription and show their results on past matches. Results like that are easy to fit to history. How AI betting tips do in independent tests we describe separately: at the 2026 World Cup none of the four leading language models predicted results better than the odds. In our test of 89 simple rules, described in why a betting model is not enough, none made a profit on matches it had not seen before. The same goes for surebet software sold as "guaranteed profit": real surebets and value bets earn small margins, and bookmakers sooner or later limit the accounts that take them.
"Investing with a tipster" and betting on your account
The scammer offers to "bet for you": he asks for the login and password to your bookmaker account, for a deposit into his own account or for a transfer he will "multiply" within a week. Handing over access to your account breaks the terms of every licensed bookmaker and can end with the account being closed, and money sent to someone else's account is usually gone for good.
Impersonating a bookmaker
A text or an email about a "bonus to claim", a "blocked withdrawal" or "account verification", with a link to a site that looks just like the bookmaker's. Once you type in your login details or card details, the scammer takes over the account or the money. Always type the bookmaker's address yourself or use its app, never a link from a message.
The maths: a seller of sure tips would make money on his own
Suppose someone really hits 90% of his tips at odds of 1.50. Every £100 he stakes then brings him, on average, 0.9 × 1.50 × £100 − £100 = £35 profit.
With 20 bets a month of £1,000 each, the expected profit is 20 × £1,000 × 35% = £7,000 a month, with no customers, no adverts and no risk. Why would someone like that sell tips at £99? The answer is always the same: because the tips do not exist, and selling them pays more reliably than betting.
For comparison, the market is very well calibrated. In our database of 104,000 matches from 37 leagues (2015–2026), favourites given a 70–80% chance by the odds won 75.5% of their matches. A "banker" at 1.30 needs a strike rate of 1 / 1.30 = 76.9% just to break even, and in practice it loses roughly one match in four.
Why a short tipster record means nothing
Even an honest tipster who does not lie about his results can have a great record purely thanks to luck. We checked this in a simulation on random 1X2 bets from our database. The table shows the share of bettors who are in profit after a given number of bets:
| Number of bets | Fair odds, no edge | 5% edge |
|---|---|---|
| 50 | 47.0% | 54.9% |
| 100 | 47.0% | 58.9% |
| 500 | 46.4% | 71.3% |
| 1,000 | 45.2% | 79.1% |
After 100 tips a bettor with no edge at all is in profit 47% of the time, and one with a real 5% edge is in the red about 41% of the time. So a hundred tips cannot tell an expert from chance.
Now an illustrative example. Picture 1,000 tipsters with no knowledge at all, each publishing 100 tips at fair odds of 2.00. Purely by chance, about 28 of them will have a yield of +20% or more, and about 10 a yield of +24% or more. Those are the ones who make it into the rankings, the adverts and the paid groups. The other 972 records interest nobody.
How to check a tipster before you trust him
- A verifiable record. Every tip published before the match, with the date and time, somewhere the author cannot edit.
- All the tips, not a selection. The losses must be as visible as the wins.
- A large sample. A few hundred tips is the minimum, and at odds above 3.00 you need even more.
- Odds you could actually get. Yield worked out at the odds available from licensed bookmakers when the tip was published, not at the highest price found anywhere.
- The closing odds. If the odds regularly fall after the tips are published, that is a better sign than the profit itself.
How to work out yield and the break-even point yourself we show in our betting tracker spreadsheet guide.
Warning signs
| Sign | Why it is a problem |
|---|---|
| "Sure tip", "fixed match", "100% guaranteed" | nothing is certain in sport, and selling fixed results is always a scam |
| A record shown only as screenshots | screenshots are easy to doctor or cherry-pick |
| Time pressure: "today only", "last places left" | the point is that you have no time to check |
| Payment by bank transfer to a private account, in crypto or with gift cards | the money is hard to get back |
| A request for the login to your bookmaker account | it breaks the terms and puts your account and your money at risk |
| High odds on "bankers" (5.00, 10.00, 20.00) | odds of 10.00 mean the market gives about a 10% chance |
| A refund for a loss "in the next package" | another fee instead of your money back |
| No company details, terms or contact | there is nobody to hold responsible |
What to do if you have been scammed by a tipster
- Stop paying. Do not pay a "fee to release your winnings", a "tax" or a "last package that will win your losses back". That is the typical second stage of the scam.
- Keep the evidence. Save the conversations, account numbers, payment confirmations, profile names and links. Do not delete any messages.
- Contact your bank. If you paid by card or bank transfer, tell your bank as soon as possible. Cancel your card if you gave its details, and ask whether the payment can be disputed or refunded.
- Change your passwords. Especially for your bookmaker account, your email and your online banking. If someone had access to your bookmaker account, tell the bookmaker.
- Report the fraud. In England, Wales and Northern Ireland, report it to Report Fraud, the national service that replaced Action Fraud, online or on 0300 123 2040, with the evidence you have gathered. In Scotland, call Police Scotland on 101.
- Report scam messages and websites. Forward scam emails to the National Cyber Security Centre at report@phishing.gov.uk and scam texts to 7726, and report fake websites through the NCSC's online form.
- Report the profile or group to the platform it operates on.
Watch out, too, for "recovery agents" who get in touch after a scam and offer to help for a fee. They are often the same people, or yet more scammers.
Losing money to a scam often pushes you to win it back quickly with bets. That is a trap we describe in our article on betting psychology. It is better to take a break and go back to the bankroll rules.

Summary
- "Fixed matches" and "sure tips" for money are always a scam.
- Someone who hit 90% at 1.50 would bet on his own instead of selling tips.
- A hundred tips mean nothing: among 1,000 tipsters with no edge, a few dozen will show great results by chance.
- Doubling the stake at 2.00 puts £1,260 at risk to win £20, and with the bookmaker's margin it loses money on average.
- After a scam: stop paying, keep the evidence, call your bank and report it to Report Fraud, or to Police Scotland in Scotland.
FAQ
Yes, always. Nobody with sure information about a result would sell it to strangers online. On top of that, cheating at gambling, which includes interfering with a sporting event that people bet on, is a criminal offence in Great Britain, so the buyer has no protection at all.
Usually not. An honest tipster would need a verifiable record of several hundred tips with an edge that survives the bookmaker's margin, and that is very rare. Most paid groups show only selected, winning bets.
Check whether all his tips are published before the match somewhere he cannot edit, whether his record covers several hundred bets and whether his yield is worked out at odds available from licensed bookmakers. Screenshots and one-off wins are not proof.
No. At odds of 2.00, a win after five losses (stakes from £20 to £640) returns £1,280 on £1,260 staked, a profit of £20, your first stake. Without a margin the system is worth exactly zero on average; at a 5% margin a cycle of up to six bets loses £6.44 on average. And long runs of losses quickly call for stakes you do not have.
Stop paying anything more, keep the conversations and payment confirmations, contact your bank and report the fraud to Report Fraud (reportfraud.police.uk or 0300 123 2040), or to Police Scotland on 101 if you live in Scotland. Forward scam emails to report@phishing.gov.uk and scam texts to 7726.
Because betting is very volatile. If 1,000 people with no edge each publish 100 tips at odds of 2.00, about 28 of them will reach a yield of +20% or more purely by chance. Those are the results you then see in the adverts.
