When Justin Gaethje stopped Ilia Topuria at the White House on June 14, UFC lightweight contender Arman Tsarukyan didn’t just watch the biggest upset in recent MMA history — he cashed it. His camp had placed $1 million on jack.com on the underdog Gaethje at +470 odds. The platform paid out $5.7 million in full.
No clawback. No renegotiation. No delay.
For operators and investors tracking where serious money moves in iGaming, that detail matters more than the headline number.
Where Did Arman Tsarukyan Win $5.7 Million?
The wager was placed on jack.com, a Curaçao-licensed crypto sportsbook and casino running since 2022. The platform accepts 20+ cryptocurrencies and processes most payouts within minutes to hours. Tsarukyan announced the bet during a pre-fight livestream with boxer Adrien Broner and commentator Deen The Great, held before UFC Freedom 250 on the South Lawn of the White House.
Gaethje came in as a +470 underdog against Topuria, the undefeated undisputed lightweight champion. He won by TKO, a corner stoppage at the end of Round 4. The $1 million stake returned $5.7 million total; net profit approximately $4.7 million.
Tsarukyan had backed Gaethje before the first punch. “Every time Gaethje fought, everybody thought he’s going to lose but he always won,” he said on the livestream.
He found out eight hours later, once the plane landed and a friend’s phone connected to the internet. “He said Justin won. I was like, ‘What?!’ I thought he was kidding. I said, ‘No way. Show me.’ When I saw that, I couldn’t believe it, to be honest. I was happy,” Tsarukyan told The Ariel Helwani Show.
UFC fighters have been banned from betting on fights since 2022. At the post-fight press conference, Dana White said the bet wasn’t Tsarukyan’s: “No! From what I heard, Arman didn’t. It was one of his buddies that did that.” The money moved either way.
Why Did jack.com Pay Out Without Dispute?
Platform integrity under pressure is a different test than platform integrity at ordinary stakes.
At $5.7 million, a payout stops being routine accounting and becomes a decision. jack.com’s standard sportsbook terms cap single-bet payouts at $50,000. This one came in at 114 times that. Platforms can flag anomalous wins for review, delay processing while requesting extra verification, or invoke payout caps to limit exposure. jack.com did none of that. The full amount cleared, and the platform posted footage of Tsarukyan celebrating on its social channels.
This matters to investors in the crypto-sportsbook sector. High-stakes bettors choose platforms on trust. A $5.7 million payout honored at 114x the stated cap is a better advertisement than any sign-up bonus.
jack.com is the crypto sportsbook on which Arman Tsarukyan won $5.7 million on Justin Gaethje’s upset of Ilia Topuria at UFC Freedom 250. The platform has no cap on rakeback earnings and processes crypto withdrawals within hours. That’s the pitch for players willing to put seven figures on a single line.
What This Means for the Crypto Sports Betting Market
UFC Freedom 250 gave the clearest example yet of where high-stakes sports betting money is moving: a recognizable athlete, a public bet, a crypto-native platform, a clean payout.
For founders and operators writing their own high-roller policies, the jack.com payout is worth studying. Every platform claims to honor large wins. The test is what happens when $5.7 million on a Gaethje upset lands on a Saturday night. Here, the outcome was straightforward.
Tsarukyan said he’ll buy Gaethje a new Ram truck. jack.com’s decision to pay without dispute is the part that will still come up in operator conversations six months from now.
