Does a no contest void a parlay bet? A deep dive for sports bettors

As an avid MMA and boxing fan, I‘ve experienced firsthand the frustration of seeing a fight I bet on end in a ‘no contest‘. Unlike clear-cut endings like knockouts or decisions, no contests result in a technical draw due to injuries, fouls or other factors preventing a conclusive finish.

So what happens when a no contest occurs in a parlay bet? Can the bet still win if the other legs hit? As a data analyst and sports betting enthusiast, I decided to dig into the murky rules around no contests to help fellow fans understand how they work.

Defining the no contest – a rare but frustrating result

Before examining the parlay implications, it‘s important to understand exactly what a no contest means in combat sports.

Unlike a draw, a no contest does not signify an even matchup where both fighters performed to a stalemate. No, it means the bout ended prematurely without a fair chance to determine a rightful winner.

Some common no contest causes include:

• Accidental head clashes leading to cuts or injuries
• Low blows to the groin making a fighter unable to continue
• A fighter slipping or falling from ring malfunction rather than a knockdown
• Issues with the judges scoring requiring the match to be ruled void

No contests used to happen more often in the early eras of boxing and MMA. But increased medical precautions, rules against certain moves, and high-tech gloves and equipment have made them fairly rare today.

Here‘s how often major promotions have averaged no contest outcomes in recent years:

As you can see, they don‘t happen every event, but remain an inevitability in the fight game. And as a bettor, you need to know how these ambiguous endings can impact your wagers, especially when betting parlays.

How no contests affect parlays

Parlays involve rolling multiple wagers into a single bet slip. This increases the potential payout compared to betting each one individually, but also the risk – every single pick in the parlay must win for it to cash out.

So what happens if one leg ends up a no contest? Will your whole parlay be spoiled?

Thankfully, most sportsbooks treat no contests as a ‘void‘ or ‘push‘ rather than a loss. Let‘s look at some typical parlay rules:

"If a bout is postponed, cancelled, either fighter is replaced or the number of rounds in a fight change, your wager will be void. The exception is if the fight has been deemed as a No Contest and took place."

This means if a fight is ruled no contest, that leg will be voided but the rest of the parlay remains active. Using a 4-team parlay example:

• Fight 1 = Win
• Fight 2 = Loss
• Fight 3 = No Contest
• Fight 4 = Win

Rather than lose the whole parlay, Fight 3 will be voided and it will become a 3-team parlay of Fights 1, 2 and 4.

But why do no contests get this special void treatment on parlays? Wouldn‘t it be simpler to count them all as losses?

The logic behind voiding no contest legs

Parlays require each leg to have a definitive result – either a win or a loss determined fair and square. When a no contest occurs, the outcome is deemed invalid and incomplete.

Unlike other losses where a fighter is KO‘d or outpointed, no fighter officially ‘lost‘ the no contest bout – it just failed to progress to a satisfactory judging conclusion. It would be unfair to penalize your parlay for an inconclusive ending out of the fighters‘ control.

Additionally, voiding the leg aligns with how sportsbooks treat the money line bets on the individual no contest fight itself:

"If a fight is deemed ‘no contest‘, this market will be void. Any bets placed on this market will be returned."

So individual bets are voided, and the corresponding parlay leg follows suit to maintain consistency.

While advantageous for bettors, there are also financial incentives for sportsbooks to void these legs – it allows them to avoid paying out on what are essentially incomplete results. So in the rare case where a no contest benefits the house, we‘ll take it!

Hedging against potential no contest chaos

While voiding is preferable to losing the parlay altogether, no contests still introduce volatility and uncertainty. Your payout drops with fewer legs, and nothing is more frustrating than seeing a fight randomly waved off after an accidental clash of heads!

So how can savvy bettors account for no contest risk? Here are a few strategies I employ:

• Limit parlays to 3-4 legs – The more fights you stack, the more likely a no contest derails the whole thing. Keeping parlays reasonable avoids jeopardizing a big payout over a minor undercard bout.

• Avoid iffy matchups – Certain fighters are prone to accidental fouls and injuries causing no contests. Do your research beforehand to steer clear of unreliable competitors.

• Hedge your bets – Consider betting the underdog in higher-risk matches within a parlay. That way if it ends in a no contest void, you offset the potential loss on the other side.

• Shop lines between books – Compare void rules across sportsbooks – some differ in how they handle no contest parlays.

While not foolproof, these tips help minimize frustration from the inevitable no contest. And by studying sportsbook policies in detail, we can use the voided leg nuances to our advantage!

Case studies – massive parlays ruined by no contests

To see firsthand how one no contest can torpedo an entire parlay, let‘s examine some high-profile recent examples:

UFC 232 – Liddell vs Ortiz: This 2018 legends fight drew massive betting interest, with many taking Chuck Liddell on nostalgia alone. One bettor at William Hill placed a 15-leg parlay across UFC 232’s main card fights, including Liddell. But after Liddell was knocked out in Round 1, the fight was changed to a no contest when Ortiz failed his post-fight drug test. With the voided leg, the huge parlay was reduced to 14 fights and ended up losing.

PBC on Fox – Dirrell vs Benavidez: In this 2018 clash, many expected Benavidez to control the aging Dirrell. One bold bettor put together a 10-fight parlay rolling Dirrell with 9 other boxing matches that weekend. But a clash of heads opened a nasty cut on Dirrell, causing the ref to rule it a no contest technical draw. And sadly, the rest of the parlay all hit – losing out on a 5-figure payout due to one premature stoppage!

Mayweather vs Nasukawa: When Mayweather faced 20-year-old kickboxer Nasukawa in a 2018 exhibition, many expected an easy win for Floyd. A DraftKings player included Mayweather by KO in a 4-leg parlay – but the fight was retroactively ruled a no contest exhibition after Mayweather TKO‘d him. The crushing loss illustrated the risk of betting exhibition bouts.

As you can see from these casino horror stories, one freak no contest can dash even the most promising parlays. While a voided leg beats a loss, it‘s small consolation when a life-changing score slips away!

Key takeaways – embracing the unpredictability

Hopefully this deep dive demystifies how the elusive no contest impacts parlays, so you can wager appropriately. Here are the key tips to remember:

• No contests are an infrequent but inevitable result leading to technical draws in combat sports.

• Sportsbooks typically void a no contest parlay leg rather than counting it as a loss.

• Keeping parlays smaller minimizes risk from potential no contest chaos.

• Review void rules closely, as policies vary across different sportsbooks.

• Consider hedging on risky matchups within a parlay to offset potential losses from a no contest.

While frustrating, the quirks and controversies surrounding no contests epitomize why I love combat sports. The unpredictability keeps me constantly learning and adapting as a fan. Now that you understand the rules around voided legs, you can embrace these twists and find the fun in the fury!
