Real example: Italy's Serie A corners
This is how an AI assistant with web search can answer when asked for the best Serie A corners bet over the next 3 days (football, corners market, 3-day period). It is an illustrative screenshot: it teaches you how to read the answer and is not a betting recommendation.
How to read this example
- It promises nothing: the heading says «Preliminary candidates» and makes clear these are not three confirmed bets, just options to review. That is the «no bet» exit you ask for in the prompt.
- Every figure comes with a source: TipsAudit, Road2Sushi and Data Fut are cited next to each number, exactly as the prompt asks («cite the source and the date»).
- It separates probability from odds: Torino–Como (over 8.5 corners) has published odds of 1.90 and a probability between 53% and 55%. At 53% the expected value is almost zero (+0.7%); at 55% it rises to +4.5%. That is why the label says «marginal value».
- No odds, no recommendation: for Sassuolo–Lazio (under 9.5) there is only a probability (57.4%) and no bookmaker odds; the answer itself says that is not enough to recommend it. At 57.4% the minimum odds with value would be about 1.74.
- Fair odds are not the bookmaker's odds: for Roma–Cagliari (over 8.5) 52% equals fair odds of about 1.92, but that is not a verified price: you have to check what your bookmaker pays.

How to use the builder
- Pick the sport and the period: 3 days, 7 days or the best bet of the month.
- Pick the market (corners, goals, both teams to score, props…) and, if you like, the competitions and the minimum odds.
- Press «Build prompt», copy it and paste it into ChatGPT with web search turned on.
- Verify what it answers: odds, line-up and kick-off time at your bookmaker.
What a good betting prompt contains
- Today's date and the window, so it does not talk about past matches.
- Web search with sources, so it cites where each data point comes from.
- Its own probability and the minimum odds, to know whether there is value.
- A reason not to bet and the option to answer «no bet».

5 example prompts to guide you
This is what a well-built prompt looks like. Every example uses the same pieces as the builder: the date and the window, web search with sources, what to check for each market, the answer format, the minimum odds and a «no bet» exit. Use them as they are or as a model to edit your own. Each one is explained in the guide Top 5 ChatGPT prompts for betting on the next 3 days.
1. Corners over the next 3 days
Act as a cautious quantitative sports-betting analyst who never makes up data. Today is [TODAY'S DATE]. Use web search to find the [SPORT] matches in [COMPETITIONS OR «the main leagues»] between today and [TODAY'S DATE + 3 DAYS]. For each relevant match confirm, citing source and date: likely absences and line-up, referee and the corners line offered by bookmakers. Calculate each team's corners won and conceded in their last 5 games (home and away separately), their style (crosses, wing play) and the context (who needs to come from behind). Give me the 3 best corner options (totals or by team) with: match and kick-off time, exact bet, line and odds with their source, your estimated probability, the minimum odds that still have value, the main risk and one reason NOT to bet it. If none has value, tell me. Do not guarantee results.
2. Goals: over/under and team goals
Act as a quantitative sports-betting analyst who never makes up data. Today is [TODAY'S DATE]. With web search, list the [SPORT] matches in [COMPETITIONS] until [TODAY'S DATE + 3 DAYS]. For each one bring, with source and date: goals scored and conceded in the last 5 games (home/away), expected goals (xG) if available, absences among forwards and the goalkeeper, and the over/under [LINE, e.g. 2.5] goals odds. Estimate your probability that the line is exceeded and compare it with the implied probability of the odds. Give me the 3 best options with minimum odds that still have value, the main risk and one reason NOT to bet it. If there is no value, tell me.
3. Both teams to score (BTTS)
Act as a quantitative sports-betting analyst who never makes up data. Today is [TODAY'S DATE]. With web search, find the [SPORT] matches in [COMPETITIONS] until [TODAY'S DATE + 3 DAYS]. For each one give me, with source and date: in how many of each team's last 5 games both sides scored, percentage of games without conceding, absences among defenders and the goalkeeper, style (low block or high press) and the odds for «both teams to score: yes» and «no». Estimate your probability and compare it with the odds. Give me up to 3 matches with minimum odds that still have value, the main risk and one reason NOT to bet. Do not use head-to-head history as the main argument.
4. Player props (you choose the sport and the stat)
Act as a quantitative player-props analyst who never makes up data. Today is [TODAY'S DATE]. Sport: [SPORT]. Stat: [STAT, e.g. points, shots on target, strikeouts, yards]. With web search, look at the games until [TODAY'S DATE + 3 DAYS] and choose up to 3 players. For each one confirm, with source and date: starting status and expected minutes, role and usage, average over the last 10 games and the last 5, team injuries that change his role, the opponent's defence or pace and the line offered by [BOOKMAKER]. Calculate your projection and tell me whether the over or the under is better than the line, with your estimated probability and the minimum odds that still have value. If you cannot confirm the line, ask me for it. Finish each one with a reason NOT to bet it.
5. The best bet of the period (3 days, 7 days or the month)
Act as a cautious quantitative sports-betting analyst who never makes up data. Today is [TODAY'S DATE]. I need the best [SPORT] bet for the period [TODAY → END DATE: 3 days / 7 days / 30 days], in the [MARKET] market. Use web search and cite the source and date of every data point. Review all matches in the period in [COMPETITIONS], discard those without enough information and keep one main bet and two alternatives. For each: match and kick-off time, exact bet, current odds with their source, your probability and the data behind it, the minimum odds that still have value, the main risk and one reason NOT to bet it. If the window is long, tell me which data I should re-check before each match. If none has value, tell me. Do not guarantee results.
Frequently asked questions
Does the builder give me bets?
No: it builds text for you to ask ChatGPT. Any bets it suggests must be verified. If you want picks already worked out, see Gambeta's free predictions.
Does it work with AI assistants other than ChatGPT?
Yes, the text works with any assistant that has web search. The «Open in ChatGPT» button is just a shortcut.
Which period should I choose?
For 1 to 3 days the information is more reliable. With 7 days or the best bet of the month, the prompt asks the assistant to flag what to re-check before each match.
