With 18 professional wins, including 8 submission victories, Serghei Spivac has built his reputation one fight at a time. The Moldovan heavyweight has gone from the European MMA circuit to becoming a familiar face in the UFC, collecting notable victories and performance bonuses along the way.

But there is more to Spivac’s journey than his record inside the Octagon. His growing profile has also raised questions about the financial rewards that come with life as a UFC heavyweight. Serghei Spivac’s net worth offers a closer look at his career earnings, reported brand associations and lifestyle, revealing another side of the fighter’s journey.

What is Serghei Spivac’s Net Worth?

According to Sporty Salaries, Serghei Spivac’s net worth is estimated to be more than $1.8 million. The Moldovan UFC heavyweight has built his wealth primarily through his professional MMA career, with additional income reportedly coming from endorsement deals.

Spivac has been competing in the UFC since 2019, and his reported fight purses have grown significantly as his profile has risen. Some of the biggest reported payouts include $300,000 plus a $100,000 win bonus for his 2023 victory over Derrick Lewis, followed by a reported $350,000 purse against Ciryl Gane later that year. His 2024 win over Marcin Tybura reportedly brought him $350,000 plus a $100,000 win bonus.

However, his exact wealth is difficult to verify because UFC fighters’ complete compensation, including sponsorships and other bonuses, is not always publicly disclosed. For example, Spivac’s disclosed UFC 311 purse in January 2025 was reported as $100,000.

Thus, $1.8 million-plus should be viewed as an estimate rather than a confirmed figure. His continued UFC career and growing heavyweight profile could push that figure higher.

Serghei Spivac’s Career Earnings

Serghei Spivac’s estimated total career earnings sit between $1.2 million and $1.5 million across his 15-fight UFC career. Because the promotion rarely releases official payout data, this total is calculated by combining public athletic commission filings, win bonuses, performance bonuses, and Venum promotional incentive pay. 

While tracking databases like Tapology list his minimum legally disclosed baseline earnings at $114,000, that figure only reflects specific state commission reports and excludes his major main-event payouts. His largest single-fight payday came at UFC Vegas 95 in 2024, where he secured $516,000 for defeating Marcin Tybura, a sum that included a $350,000 base, a $100,000 win bonus, a $50,000 Performance of the Night bonus, and $16,000 in sponsorship pay. 

More recently, at UFC 311 in January 2025, Spivac earned a flat $100,000, despite a first-round TKO loss to Jailton Almeida. These high-profile payouts contrast sharply with his early UFC career, such as his 2019 victory over Tai Tuivasa at UFC 243, which netted him just $27,500. 

Serghei Spivac’s Professional Career

Serghei Spivac has built a reputation as one of Moldova’s most accomplished heavyweight MMA fighters. Turning professional in 2014, he competed on the European regional circuit before joining the UFC in 2019. His early career was particularly impressive, as he went unbeaten through his first nine professional bouts and captured the WWFC Heavyweight Championship.

Spivac made his UFC debut at UFC Fight Night 151 in May 2019, stepping in against Walt Harris, but suffered his first professional defeat via first-round TKO. He bounced back later that year by submitting Tai Tuivasa at UFC 243, securing his first UFC victory.

Over the following years, Spivac established himself as a consistent heavyweight contender with notable wins over Aleksei Oleinik, Augusto Sakai, Derrick Lewis and Marcin Tybura. His 2023 submission victory over Lewis was a major career highlight.

As of August 2026, Spivac owns an 18-6 professional record, including seven knockout wins, eight submissions and 11 first-round finishes. He most recently defeated Ante Delija by unanimous decision in February 2026.

Serghei Spivac’s Brand Endorsements

Serghei Spivac has also built a modest commercial profile alongside his UFC career. The Moldovan heavyweight was associated with SkinnyBets and Crypto.com, with both brands appearing among his reported endorsements. The publication attributed the information to Spivac’s official Instagram account.

That said, there is currently no reliable public information detailing the value, duration, or contractual terms of either partnership. It is consequently safer to describe SkinnyBets and Crypto.com as reported brand associations rather than confirmed long-term endorsement contracts. Spivac’s commercial earnings remain undisclosed, making it difficult to determine how much these partnerships have contributed to his overall income.

Serghei Spivac’s journey shows that success in the UFC is about more than what happens inside the Octagon. From 18 professional wins and eight submission victories to reported UFC purses, performance bonuses and brand associations, each chapter has added to his growing profile. While Serghei Spivac’s net worth remains difficult to pin down precisely, one thing is clear: his career has created both sporting credibility and financial potential. And with more fights ahead, the next chapter could make his numbers even more interesting.
