Key Takeaways
As the CEO of Tether, Ardoino is among the wealthiest figures in the digital asset space. But his journey to the top began far from global finance.
His wealth reflects the remarkable rise of Tether itself, a company that has evolved from a niche stablecoin issuer into a financial powerhouse, managing over $100 billion in U.S. Treasuries and generating billions in annual profits.
As of May 30, 2025, Paolo Ardoino’s net worth is estimated at around $9.5 billion, according to Forbes.
This valuation is largely attributed to his estimated 20% ownership stake in Tether, the company behind USDT, the world’s largest stablecoin by market capitalization.
Tether’s business model involves issuing USDT tokens pegged to the U.S. dollar.
The funds received from issuing these tokens are invested in assets like U.S. Treasuries, gold, and Bitcoin.
By the end of 2024, the company reported profits exceeding $13 billion, with U.S. Treasury holdings reaching an all-time high of $113 billion.
As of March 31, Tether reported top-line figures of $149.28 billion in total assets against $143.68 billion in liabilities for fiat-backed stablecoin holdings, positioning Tether among the largest holders of U.S. Treasuries globally.
“I’ve been a developer since I was eight,” Ardoino said in an interview with the Washington Reporter.
While other children spent their free time outdoors, he was often indoors, immersed in programming. He spent so much time on basic programs like Microsoft Word and Paint that he got bored, and eventually taught himself to code so he could make his own games.
His passion for computer science took him to the University of Genoa, where he studied that alongside math.
Ardoino’s first job was at a hedge fund in 2011, designing trading systems. Just two years later, he founded his first company in London, Fincluster, which traded software products for hedge funds.
In 2014, Ardoino joined the Bitfinex crypto exchange as a software engineer, where he was tasked again with trading engine development and platform scalability.
In late 2016, Paolo transitioned to the role of chief technology officer (CTO).
In 2017, he took on the same CTO role at Tether, a sister company to Bitfinex.
Tether is a blockchain-based platform that issues stablecoins, digital tokens that are pegged to real-world currencies, most notably the U.S. dollar.
Its flagship product, USDT, is the world’s largest and most widely used stablecoin by market capitalization. In December 2023, Ardoino became Tether’s CEO.
“Since I took the reins as CEO, we have transformed Tether from just being a stablecoin company,” Ardoino told Forbes last year.
“Though saying we are ‘just a stablecoin’ undersells our impact because USDT is the biggest stablecoin in the market, the biggest by volume, bypassing bitcoin, ether and many other tokens combined,” he added. “It’s growing its user base daily and has more than 350 million users globally.”
Tether’s financial growth has been remarkable.
By the end of 2024, the company’s profits exceeded $13 billion.
Additionally, Tether’s market capitalization has also seen significant growth, surpassing $135 billion in December 2024.
Tether currently controls approximately 75% of the stablecoin market.
In October 2024, Ardoino said Tether held over 82,000 Bitcoin, and owns U.S. Treasuries worth approximately $100 billion.
Ardoino said he welcomed other stablecoins, as Tether has made more money than they will ever need.
He claimed that Tether’s real competitive edge has been in emerging markets—countries with weak or failing banking systems.
“Tether is successful because we serve as their checking and sales accounts,” he told Forbes.
“So if State Street or anyone else wants to come into those countries and compete with us, we are happy because, in the end, we’ve made more money than we could believe and think and dream for hundreds of years.”
“So if someone will step in and gain another 300 million users and help those countries, that’s great. I mean, we are still humans and believe in humanity’s progress,” he added.
Despite its dominance, Tether’s rise has been met with ongoing regulatory scrutiny.
Tether’s lack of a full, independent audit has remained a key issue for regulators for almost a decade. In some cases, exchanges have delisted USDT in order to comply with new regulatory frameworks targeting reserve transparency.
On February 4, 2025, Tennessee Republican Senator Bill Hagerty introduced the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, a proposed regulatory framework for stablecoin payments and settlements.
Under the GENIUS Act, all U.S. dollar-denominated stablecoins must be backed by assets such as U.S. dollars, treasury bills, federal reserve notes, and similar instruments.
This has intensified scrutiny on Tether, which has built a large reserve base consisting of cash, cash equivalents, and other short-term deposits to maintain its 1:1 peg with the U.S. dollar.
While Tether’s reserves have been reviewed and attested to by accounting firm BDO Italia, critics argue this falls short of a full, independent audit.
Ardoino has defended the company’s choice, claiming that major auditing firms represent a “reputational risk” to Tether.
Nonetheless, with the GENIUS Act advancing, Tether may soon be forced to fully comply with stricter reserve requirements or risk losing access to the U.S. market entirely.
“When you’re trying to be a disruptor, in a good sense, you are going to always be attacked by the establishment.”
“Nobody in Europe or the United States really needs a stablecoin.”
“If someone will step in and gain another 300 million users and help those countries, that’s great. I mean, we are still humans and believe in humanity’s progress.”
