A single win bet is a straightforward bet where you place your wager on one outcome in a particular event. If your chosen outcome wins, you win the bet. Heres an examplw

Example: You're betting on a football match between Team A and Team B. You decide to place a single win bet on Team A to win the match.

Bet: £10 on Team A to win.
Odds: 2.50 (which means if Team A wins, you wil get 2.50 times your stake).
Outcome: If Team A wins, you rexeive £25 (your £10 stake + £15 profit).
If Team A loses or the match is a draw, you lose your £10 stake.

So, a single win bet focuses only on one outcome—Team A winning in this case.

Q: Largest single bet ever recorded?

The largest single bet ever recorded is believed to be a $50 million wager placed by an anonnymous gambler in 2021. This massive bet was placed on the Super Bowl between the Tampa Bay Buccaneers and the Kansas City Chiefs. The bet was made through a sportsbok/booky in Nevada, which is known for handling large wagers.

This bet is notable not only because of its sheer size but also because it involved a highprofile sporting event. However,, its worth noting that large wagers of this magnitude are typically kept private, and there could be larger bets placed in other forms of gambling or offshore markets that remain unreported.

Q: Did the $50m bet actually happen, or is it a myth?
The $50 million wager I mentioned is often cited, but its actually an estimate based on repoorts of a massive wager around the 2021 Super Bowl. However, the largest recorded bet on a single event might not be that specific one, as details about the largest wagers are often kept confidential, especialy if they happen in private or unregulated market.

One of the most famous verifiable large bets in recent years comes from Billy Walters, a legendary Las Vegas gambler, who reportedly placed a $3.5 million bet on the 2010 Super Bowl. There are also reports of $10 million wagers in certain private betting circles.

There are still rumoors and unconfirmed reports about even larger bets, sometimes in the range of $100 million or more in off-the-books or private settings.

In short, the exact largest single bet ever recorded is somewhat murky, but the reported 50 million dolar Super Bowl bet is among the most talked-about in recent media.

3.4m dolar bet won and amounted to $6.18 million
Texas furniture store owner Jim "Mattress Mack" McIngvale placed a massive $3.46 million bet on the underdog Tampa Bay Buccaneers in Super Bowl LV, belieeving in their talent and Tom Brady’s leadership.

This meant the Bucs were the underdogs, and for McIngvale to win, Tampa Bay needed to either win outright or lose by no more than 3 points. If the Buccaneers covered the spread, McIngvale stood to collect $6.18 million, including bth his wager and winnings. If they lost by mre than 3 points, he'd lose the full $3.46 million.

The bet paid off big when the Bucs won, earning McIngvale one of the largest known Super Bowl wagers ever. As part of his promotion, customers who spet $3,000 or more on a matress at his store got their money back, thanks to Tampa Bay's victory.

Win Single On Different Odds Types

Let’s use a hypothetical bet where you wager £10 on a team to win, and the odds for the bet are represented in UK fractional, American moneyline, and EU decimal formats.

I'll example for how to calculate the potential return and the mathematics behind each type of odds.

Scenario: Team A to win with a £10 bet
>> UK Fractional Odds: 5/2
>> American Moneyline Odds: +250
>> EU Decimal Odds: 3.50

1. UK Fractional Odds (5/2)
In fractional odds like 5/2, the number 5 represents the potentiaal proft you can make on a 2 unit stake (in this case, £2). So for every £2 you bet, you stand to win £5. To calculate your return:

Formula:
Profit = (Stake × Odds Numerator) ÷ Odds Denominator
Total Return = Stake + Profit

Calculation:
Profit = (£10 × 5) ÷ 2 = £25
Total Return = £10 (Stake) + £25 (Profit) = £35



2. American Moneyline Odds (+250)
With positive American odds (+250), for every $100 wagerd, you will win $250 if your bet is succesful. To convert to a profit for a £10 stake:

Formula:
Profit = (Stake × Moneyline Odds) ÷ 100
Total Return = Stake + Profit

Calculation:
Profit = (£10 × 250) ÷ 100 = £25
Total Return = £10 (Stake) + £25 (Profit) = £35

3. EU Decimal Odds (3.50)
In decimal odds, the number represents the totl return for each £1 bet (including the original stake). To calculate the potential return:

Formula:
Total Return = Stake × Decimal Odds

Calculation:
Total Return = £10 × 3.50 = £35

Summary:
>> UK Fractional Odds (5/2): Total Retrn = £35
>> American Moneyline Odds (+250): Total Return = £35
>> EU Decimal Odds (3.50): Total Return = £35

As you can see, the outcome is the same across al formats in this example, with a total return of £35, which includes your original £10 stake and £25 in profit.
