On April 10th, 2025, a French punter made headlines by turning a €50 stake into €1,047,171 on the betting platform Winamax.

The secret? A 29-leg accumulator, boosted 2x by the bookmaker for a record-setting payout — the biggest sports betting win ever recorded in France.

Impressive ? Absolutely.

Reproducible ? Not at all.

📊 A Boosted Win... With Tiny Odds of Success

Here’s what we know about the bet:

  • ✅ Stake: €50
  • ✅ Number of selections: 29
  • ✅ Total odds: 10,472
  • ✅ Total win: €1,047,171
  • ✅ Actual win without boost: €523,585

The calculation is straightforward:

€50 × 10,472 = €523,600

And what’s the implied probability of those odds ?

1 / 10,472 ≈ 0.0000955 → or 0.00955%
👉 That’s roughly 1 in 10,472

This isn't a long-term strategy — it’s a statistical outlier.

📉 Even Skilled Bettors Can’t Defy the Odds

Let’s imagine an elite bettor who wins 70% of individual bets — already an extremely rare feat.

Their chances of landing 29 wins in a row ?

0.70^29 ≈ 0.0078% → 1 in 12,700

A good bettor (55% success rate) would have:

0.55^29 ≈ 0.0000277 → 1 in 3.6 million

A casual bettor (50%)? You’re looking at:

1 in 536 million

So even with an edge, these types of wins fall closer to the lottery than logic.
