UFC 329: McGregor's Knee Went in 69 Seconds, and $4.3M of Whale Money Went With It

Conor McGregor sprinted across the canvas, launched a flying kick, and his right knee gave out underneath him. He never recovered. He slipped to the mat twice, Max Holloway landed a kick, the referee waved it off, and the comeback that had been five years in the waiting was finished in 69 seconds.

tail.bet tracked $9.24 million in real high-roller bets across 114 tickets on UFC 329, more than $7.6 million of it on the main event alone. The money had picked McGregor. The money was wrong.

$4.29 million on the wrong man

Going in, McGregor was the underdog at 2.85 to 3.20 and the whales piled in anyway. $3,971,404 was staked on McGregor to win, plus another $315,759 on McGregor to win by knockout. Call it $4.29 million on a man who lasted 69 seconds.

The single biggest McGregor ticket was $1,213,563 at 3.20, a bet that would have returned $3,883,400. The second was $1,001,000 at 2.85, good for $2,852,850. That second one is, to the dollar, the bet Drake publicly announced before the card. The Drake curse is now 1-0 at UFC 329.

Backing Holloway was the correct answer, and $3.12 million did. $1,631,768 went on Holloway straight and another $1,489,373 on Holloway by knockout.

That knockout market produced the biggest winning ticket of the night: $1,355,733 on Holloway by KO at 1.69, returning $2,291,188.

Right fighter, wrong method

Two whales found the most infuriating way to be correct.

$100,000 went on Holloway to win by submission at 11.0, a bet worth $1.1 million. Holloway won. He won by strikes. The ticket is dead.

$85,000 went on Holloway to win by decision. Holloway won. It took him 69 seconds. There was no decision to be had.

That is $185,000 lost by two people who correctly identified the winner of a fight that most of the market got wrong. Meanwhile a $10,025 ticket on the fight ending inside 2.5 rounds at 1.85 needed almost none of the night to land.

The whale who bet both corners

Before the card we flagged one account holding the three biggest bets on the fight, and pointing in both directions: $1,001,000 and $500,500 on McGregor, and $700,700 on Holloway at 1.45.

Here is how that resolved. The two McGregor tickets, $1,501,500 combined, are gone. The Holloway hedge returned $1,016,015. Net position for the night: down about $1.19 million.

The cushion did what a cushion does. It softened a $1.5 million hole into a $1.19 million one. It did not save anybody.

The co-main was even faster

If you blinked during the main event, you missed the co-main entirely.

Paddy Pimblett submitted Benoît Saint Denis in 52 seconds, taking his back and finishing with a D’Arce choke against a man ranked above him. $511,850 of whale money was on Pimblett, and it was the correct read on a fight most people expected to be a war.

The painful footnote: one whale had $100,000 on Pimblett and cashed it out before the finish. Getting the winner right and taking the early exit anyway is its own special kind of night.

And the upset that paid

The other headline fight on the card went the way of the underdog too. Mario Bautista beat Cory Sandhagen by unanimous decision, 29-28 on all three cards, taking out the number four ranked bantamweight as the number seven.

$204,547 was on Bautista, much of it at prices around 2.00 to 2.16, and it cashed. As with Pimblett, one account cashed out an $84,222 Bautista ticket early rather than ride a decision to the cards.

Elsewhere the finishes kept coming. King Green stopped Terrance McKinney, Damian Pinas knocked out César Almeida, Brandon Royval choked out Lone’er Kavanagh, and Robert Whittaker stopped Nikita Krylov. Whale money was on Green ($73,383), Pinas ($68,170) and Royval ($58,906), and all three came in.

The ledger

The main event took $7.62 million across 55 bets and paid out almost entirely to the Holloway side. The undercard took $1.60 million across 59 bets and was, by comparison, kind to the people betting it.

The lesson of the night is the one the market kept trying to tell people for weeks. Holloway was 1.44 for a reason. He had been fighting. McGregor had not fought since he broke his leg in July 2021, and this time his knee gave out before anyone had even landed a punch in anger. Nostalgia was priced at 2.85, and $4.29 million of real money paid it.
