jack.com signs UFC lightweight contender Arman Tsarukyan as first UFC athlete ambassador

jack.com, the Curaçao-licensed crypto sportsbook and casino formerly known as Jackbit, has signed Arman Tsarukyan to a multi-year, multi-million-dollar ambassador deal. For high-risk operators, the point is not the celebrity photo-op; it is the pairing of a fight schedule, UFC betting markets, and social content around a fighter who already has direct audience reach.

1. Tsarukyan is the platform’s first UFC athlete brand ambassador. jack.com said he will front marketing and content, with campaigns built around his upcoming fights and the company’s UFC betting markets.
2. Tsarukyan is an Armenian mixed martial artist competing in the UFC lightweight division. He is 23-3, has a decision win over Charles Oliveira in a lightweight No. 1 contender bout, and has been among the division’s top title contenders for more than a year without yet getting a championship fight. He is expected to get a title shot later in 2026.
3. The partnership is not coming out of nowhere. At UFC Freedom 250 on June 14, 2026, someone in Tsarukyan’s camp placed a $1 million bet on Justin Gaethje at jack.com at odds of roughly 5.70. jack.com paid out $5.7 million on the ticket that night. The event was held on the South Lawn of the White House as part of the United States’ 250th-anniversary commemorations, with roughly 4,300 guests on-site and an estimated 85,000 more at a nearby public viewing area.
4. Tsarukyan disclosed the wager during a livestream with Deen The Great and Adrien Broner, before Topuria, then a roughly -500 favorite, defended his title against Gaethje. Gaethje stopped him in the fourth round, and all seven fights on the card ended by finish.
5. UFC CEO Dana White later said at the post-fight press conference that the bet came from someone in Tsarukyan’s circle rather than Tsarukyan himself, which mattered because UFC rules bar fighters from betting on their own events. Tsarukyan later said he was mid-flight without internet access when the result came in, and that he learned Gaethje had won only after landing. He has said he plans to buy Gaethje a new truck with part of the winnings.

jack.com said discussions about a formal ambassador partnership with Tsarukyan’s camp began in the weeks after the payout. The platform processes deposits and withdrawals in more than 20 cryptocurrencies, including Bitcoin, Ethereum, USDT, and Solana, which is the operational detail that matters for PSPs: this is a sportsbook-casino setup built around crypto settlement, not just a sponsorship headline.
