A tipster is someone who publishes sports predictions. Judging them on their strike rate alone means nothing: without the odds, the stakes, the period and the sample size, 80% of bets won can perfectly well hide a net loss. What makes assessment possible is a complete record, dated, published before the events and recalculable — losses included.
The essentials in a few seconds
A tipster publishes sports predictions. To assess one, the strike rate is never enough: you need the odds, the stakes, the period covered, the size of the sample and a verifiable record.
What makes a record assessable:
- tips published before the event, dated and time-stamped;
- the odds quoted and the stake committed for every bet;
- the losses visible, not just the wins;
- a complete record that can be recalculated, over a long enough period.
Key point. Without the odds and the stakes, a success percentage says nothing about actual performance.
What is a tipster?
A tipster is someone who publishes sports predictions, free or for a fee. The word comes from tip. It describes an activity, not a shady practice: some tipsters work seriously, document their analyses and own their losses.
Distribution runs through varied channels: social media, messaging groups, dedicated sites, newsletters, sometimes a paid subscription or a "premium" area. The channel says nothing about the quality of the work.
What does vary enormously is the level of proof provided. Some publish a complete, time-stamped, verifiable record. Others show only results selected after the fact. That difference is the only real starting criterion.
Tipster, forecaster, analyst: who does what?
These words are not legal categories, but roles distinguished by what they produce.
Tipster: publishes a selection of bets to follow, often with a recommended stake.
Forecaster: forms a reasoned opinion about the outcome of a match, without necessarily suggesting a stake to follow.
Analyst: explains the data, the context and the probabilities, without concluding with a bet to play.
OddScore: does not publish a selection to be followed blindly. The aim is to show the data and the market movements so that anyone can understand what is happening before the match.
These boundaries are porous in practice. The same person can analyse a match and then conclude with a selection. What is useful is not labelling someone, but knowing what you are receiving: an explanation to understand, or an instruction to execute.
Why the strike rate is not enough
The strike rate measures the proportion of bets won. It measures neither what those bets pay nor what the losing bets cost. That is why a high percentage can sit alongside a net loss.
A tipster shows 80% success over 100 tips. The average odds of their selections are 1.10, with a constant stake of 1 unit.
- 80 bets won at odds of 1.10: each bet returns 0.10 units of net profit, so +8 units.
- 20 bets lost: each bet costs the whole stake, so -20 units.
Net result: -12 units. Eight bets won out of ten, and a loss all the same.
The mechanism is simple: the shorter the odds, the smaller the gain when the bet wins, while the loss always equals the full stake. A high strike rate at very short odds is mathematically expected, not remarkable.
"A tipster with an 80% strike rate has to be excellent."
No. Without knowing the odds, the stakes, the size of the sample and the complete record, a strike rate does not allow performance to be assessed. As the example above shows, 80% success can perfectly well coexist with a negative result.
The reverse is true too: a tipster at 35% success on long odds can post a positive result. The percentage on its own ranks nobody.
Which data to look at when assessing
A record becomes interpretable when it contains enough to recalculate the result, bet by bet.
- The number of tips published, not only the ones put on display.
- The period covered, with real dates.
- The odds quoted for each selection.
- The stake committed, in units or as a percentage of bankroll.
- The cumulative profit or loss, expressed in units.
- ROI or yield, if the record allows them to be calculated honestly.
- The complete record, losses included, with no period erased.
The detail of these metrics and how to keep them for yourself is covered elsewhere: this page only says which ones have to be visible.

Why the sample matters
Over a small number of bets, luck explains nearly everything. A tipster announcing "12 out of 15" may have been right, or may simply have had a good run. Both hypotheses remain consistent with those figures.
There is no magic threshold, and nobody should promise one. Three bearings are nevertheless enough to form a view:
- duration: a few weeks show nothing, several months start to say something;
- volume: a few dozen bets remain very noisy;
- surviving the bad runs: a record containing none at all is suspicious, because every run of bets produces them.
A long record showing negative periods is more credible than a short record that is exclusively positive.
How to verify a record
The question is not "are these results good?", but "can I recalculate them myself?".
| Point to check | What it guarantees |
|---|---|
| Are the tips published before the event? | That they were not added after the result |
| Are the date and time of publication visible? | That the chronology can be checked |
| Were the quoted odds actually available? | That the result is not calculated on a price nobody offered |
| Are the losing bets visible? | That the record is not filtered |
| Are the stakes documented? | That the profit shown matches a real commitment |
| Is the complete record accessible? | That no period has been deleted |
| Can the results be recalculated? | That the headline figure checks out line by line |
If one of those answers is missing, it is not necessarily bad faith. But the record no longer allows any conclusion about performance.
Why a screenshot of a slip proves almost nothing
A screenshot shows one bet won. It does not show the bets lost the same day, the real stake, or where that slip sits in a record.
Three limits are enough to see why the format is not proof:
- it can be cherry-picked: nothing forces anyone to publish the losing slips;
- it can be late: a screenshot posted after the match does not prove the bet was announced beforehand;
- it is isolated: one winning slip says nothing about the week's balance, still less the quarter's.
A run of winning screenshots does not mean a tipster is profitable. It means they won the bets they chose to show.
The warning signs
None of these signals proves an intent to deceive on its own. Each of them does reduce the informative value of what is on offer.
- Guaranteed profits or a promise of regular income: the result of a bet depends on an uncertain event, nobody can guarantee it.
- "Sure bet" or any vocabulary of certainty: certainty does not exist on a betting market.
- An extreme strike rate with no record available to back it up.
- An incomplete record: missing periods, a counter reset to zero, inaccessible archives.
- Deleted losses or messages erased after a bad result.
- Winning screenshots only, with no figures behind them.
- Commercial urgency: an offer about to expire, limited places, pressure to sign up immediately.
- Guaranteed recovery of past losses.
- A martingale presented as risk-free: doubling the stake after a loss raises exposure without ever removing risk.
- Unverifiable odds, quoted at levels no operator was offering at the stated time.
Responsible gambling. A stake can be lost in full. Never commit money to betting that you need for daily life, housing, bills or your emergency savings. No tip, free or paid, changes that rule. Learn more about responsible gambling.

How a tipster makes money
Understanding the business model does not tell you whether the analysis is good. It tells you where conflicts of interest can sit.
The most common models:
- a paid subscription to a selection of tips;
- a premium group or private channel with paid access;
- affiliate revenue: payment from an operator for every sign-up delivered;
- sponsorship by a bookmaker or a brand;
- advertising on an audience built around tips;
- a course or method sold separately.
None of these models is illegitimate in itself. But each creates its own incentive. Affiliate income depends on the number of sign-ups generated, not on the performance of the tips. A subscription depends on perceived satisfaction, which is not the same thing as a verified result.
A visible, openly stated business model is a good sign of transparency. A hidden model, or a bookmaker recommendation whose commercial link is not disclosed, is a bad one.
Can a good prediction lose?
Yes, and that is a central point. The result of a bet depends on an uncertain sporting event. A solid analysis can end in a losing bet, and a sloppy one in a winning bet.
That is why judging a tipster on their latest results means judging noise. What can be judged is consistency over time, transparency of method and the ability to own losses without rewriting them.
A losing bet does not mean the analysis was bad. A winning bet does not mean it was good. It is repetition over a large number of bets that starts to separate the two.
The idea of a value bet follows directly from that: it means accepting losing bets in the name of a probability estimate, rather than hunting for selections that win often.
What OddScore does, and does not do
OddScore does not publish a selection to be followed blindly. The aim is to show the data and the market movements so that anyone can understand what is happening before the match.
In practice, the platform collects the odds of several bookmakers, converts them into implied probabilities, removes the margin built into the prices and tracks how they evolve up to kickoff.
What comes out of it is not a bet to play: it is a reading of the market, to be placed back inside your own analysis and your own bankroll management.
Before following anyone, learn to measure your own results. The same criteria that serve to assess a tipster apply to your own record.

What is a tipster?
Someone who publishes sports predictions, free or for a fee. The term is neutral: it describes an activity, not a fraudulent practice.
Is a strike rate of 80% a good sign?
Not in itself. At very short odds, 80% of bets won can end in a net loss. A strike rate only becomes interpretable alongside the odds, the stakes and the size of the sample.
How many tips do you need to judge a tipster?
There is no magic threshold, but a few dozen bets over a few weeks proves almost nothing. The shorter the sample, the more of the result is explained by luck.
Does a screenshot of a winning slip prove anything?
Very little. A screenshot can be cherry-picked, posted late and cannot be placed back into a record. It shows one bet won, not performance over time.
How do you verify a tipster's record?
By checking whether the tips are published before the event, dated, with the odds quoted, the stake committed, the losses visible and a complete record that is accessible and recalculable.
Is a paid tipster more reliable than a free one?
The price says nothing about the quality of the analysis. The business model mainly tells you where conflicts of interest can sit; it does not replace checking the record.
Does OddScore publish tips to follow?
No. OddScore does not publish a selection to be followed blindly. The aim is to show the data and the market movements so that anyone can understand what is happening before the match.
