About AllSportsPredict
team of analysts publishing free predictions across football, basketball, lawn tennis and volleyball. We started in 2021 because every tipping site we could find gave us a pick and no reasoning, and half of them quietly deleted their losers. We wanted to build the opposite of that: full analysis on every fixture, a settled record that includes the bad days, and an honest position on what betting can and cannot do for you.
How we work
We publish the reasoning, not just the pick
Every prediction shows the model probability, the market implied probability and a written explanation of why we landed where we did. A tip without reasoning is a guess with a logo on it.
We publish losses as loudly as wins
Our results pages settle every tip we put out, including the ones that went badly. Any tipster showing only their winners is selling you something.
We do not manufacture tips to fill space
If our estimate matches the market price, there is no bet, and we say so. We routinely model sixty fixtures and publish on twenty-five of them.
We take no bookmaker money for placement
We are not affiliated with any operator and nobody can pay to appear in our tips or have their odds shown preferentially.
Two-stage review on everything
Raw data research first, then editorial review by a second analyst before publication. Team news is re-checked within three hours of the start time.
Responsible gambling is not a footer disclaimer
We cap our published accumulators at five legs, we explain compounding margin rather than hiding it, and we never present betting as a source of income.
One process, four models
The inputs that predict a football scoreline have almost nothing in common with the ones that decide a volleyball set, so we run four separate models rather than one generic one. What they share is the final step: a prediction only gets published if our probability estimate beats the market implied probability by more than the bookmaker margin.
- Rolling expected goals for and against across the last 10 matches, weighted towards recent form
- Home and away splits, because plenty of sides are a different team on the road
- Confirmed injury and suspension lists, checked again within three hours of kick-off
- Set-piece and penalty dependency, which distorts raw goal totals
- Fixture congestion and rotation risk for sides in continental competition
- Table motivation: title run-ins, European chases and relegation scraps
- Offensive and defensive efficiency per 100 possessions, adjusted for opponent
- Pace estimates, which drive every total points call we make
- Back-to-back and three-in-four scheduling fatigue
- Official injury reports, including probable and questionable tags
- Rotation depth, since bench minutes decide most spread outcomes
- Home court value, which varies enormously between leagues
- Surface-adjusted Elo, calculated separately for hard, clay, grass and indoor
- Service hold and return break percentages over the last 12 months
- Head-to-head results, but only those played on a comparable surface
- Match load and recovery time, including any five-setters in the previous round
- Retirement and injury history, which is critical in best-of-five events
- Altitude, ball type and roof status, all of which change court speed
- Side-out and break-point efficiency, the two numbers that decide sets
- Attack success rate split by zone, plus block points per set
- Reception quality, which determines how often a side can run its first-choice attack
- Setter availability, the single biggest injury swing factor in the sport
- Home crowd effect, which is unusually strong in Polish and Italian arenas
- Continental fixture load for sides in the CEV Champions League
The analyst team
Four analysts, each owning a sport, with a shared review process. Every prediction and article carries a named author, because anonymous tips are unaccountable tips.
Daniel Osei
Head of Football & Strategy
Eleven years working with football data, previously building expected goals models for a betting syndicate. Writes most of our strategy and bankroll material.
Focus: Football, staking strategy
Marcus Bell
Basketball Analyst
Covers the NBA and EuroLeague with a focus on pace, rotation depth and schedule spots. Built the fatigue model that underpins our basketball spread tips.
Focus: Basketball, totals markets
Elena Marchetti
Tennis Analyst
Maintains our surface-adjusted rating system across the ATP and WTA tours. Former junior circuit coach, which shows in how much weight she puts on style matchups.
Focus: Tennis, football team news
Piotr Nowak
Volleyball Analyst
Covers the SuperLega, PlusLiga and CEV Champions League. Argues, persuasively, that volleyball is the most mispriced sport available to recreational bettors.
Focus: Volleyball, value betting
Our position on gambling
Betting is entertainment that costs money. Over a long enough period the margin favours the bookmaker, and while a disciplined bettor can beat specific markets, nobody beats all of them consistently. We will never present betting as an income source, we will never sell a system, and we will never tell you a tip is guaranteed.
If your betting has stopped being fun, stop and get support. It is free and confidential.
