How much is Giancarlo Devasini Worth? Giancarlo Devasini Net Worth in 2026
Giancarlo Devasini’s net worth is estimated at $89 billion as of November 2026. Almost all of it is a share of Tether, the company behind the USDT stablecoin, which he has helped run since its early days and is believed to own about 44 to 45 percent of. In 2025 Tether paid out about $10.86 billion in dividends, slightly more than the roughly $10 billion it earned, and that single line tells you more about his money than any rich list does.

How much is Giancarlo Devasini worth in 2026?
We put Giancarlo Devasini at about $89 billion. That figure is 44.5 percent of Tether at a $200 billion valuation, and it is an estimate built on two numbers nobody has confirmed: the size of his stake and the price of a company that has never sold shares in a completed funding round. On our ranking of crypto billionaires worldwide he is No. 2, behind Binance founder Changpeng Zhao.
Public estimates for him run from under $10 billion to well over $150 billion. The gap is almost entirely the Tether valuation each one uses: older figures priced the company near $50 billion, while others multiply his stake by the $500 billion that Tether sought from investors in 2025. A few points of disagreement over his percentage, 40 to 47 percent depending on the report, add another $10 billion or so either way. Our range runs from 40 percent at $200 billion, about $80 billion, to our stake at the private-market $350 billion, about $156 billion.
How we got to $89 billion
We split Tether’s $200 billion into what can be counted and what is a bet on future profits, then take his share of each.
| Source | Our estimate | What it rests on |
|---|---|---|
| Share of Tether’s reserve surplus | $3.5 billion | The BDO attestation for September 30, 2026 showed $191.45 billion of assets against $183.5 billion of liabilities, a surplus of about $7.95 billion. His cut: $3.54 billion. |
| Share of Tether’s venture portfolio | $4.5 billion | Stakes in more than 120 companies, valued at over $10 billion in February 2026. Multiplied by his stake, that is $4.45 billion. Our assumption: this sits outside the reserve surplus, with no overlap. |
| Share of the value placed on future profits | $81 billion | The rest of the $200 billion valuation, about $182 billion, is what investors would pay for the profit stream. His slice comes to $81 billion. This is the soft part of the fortune. |
| Bitfinex stake and cash already taken out | $0 | Not counted. Bitfinex shares an owner group with Tether but publishes no accounts, and we found no record of how much of Tether’s dividends reached him personally. |
| Total | $89 billion | $3.5 billion plus $4.5 billion plus $81 billion. No tax row: the stake has not been sold. |
The $200 billion is the figure Forbes Italia put on Tether in February 2026 after talking to investors and crypto executives. The same report said shares were changing hands privately at $350 billion to $375 billion. We use the lower number because no round has closed at either price.
The $10.86 billion payout
Tether’s assurance report for 2025, covered by Grafa in February 2026, showed dividends of about $10.86 billion for the year against profits of a little over $10.1 billion. Equity fell from $7.09 billion to $6.34 billion as a result. The company paid out more than it earned.
Here is our calculation. If those dividends went to shareholders in line with ownership, his share of $10.86 billion is $4.83 billion for one year. We still leave it out of the ledger: in an earlier quarter, CoinGeek reported that much of the payout appeared to flow into Tether’s non-crypto investments, which are already in our venture row.
The profit itself has slowed. Tether reported about $13 billion for 2024 and a little over $10 billion for 2025. Crypto Briefing reported on October 30, 2026 that the first nine months of 2026 brought $4.5 billion, a pace of about $6 billion a year. By our math, a $200 billion price is 20 times 2025 profit but about 33 times the 2026 pace. His share of that pace is about $2.7 billion a year.
From medical school to the money printer
Devasini took a medicine degree at the University of Milan in 1990 and worked briefly as a cosmetic surgeon. He left after about two years to sell computer components, then a food delivery business, and several of those companies later went bankrupt. None of it hinted at the next act.
He was part of founding the Bitfinex exchange in 2012, and its owners took over Tether in 2015. In early 2016 he owned all of Tether Holdings, according to records reviewed by the International Consortium of Investigative Journalists, before at least 55 percent of his shares moved to Jean-Louis van der Velde. By around 2018 he was back to about 43 percent, the largest single stake. US regulatory filings now say he holds more than half of the voting rights, the ICIJ found.
His title changed in March 2025, when Tether named him chairman and hired Simon McWilliams as finance chief. He and his wife became Salvadoran citizens in early 2025, after Tether moved its legal base to El Salvador.
What would move the number
A closed funding round is the big one. At the $500 billion Tether sought in 2025, his 44.5 percent would be worth about $222 billion. At the private-market $350 billion, about $156 billion. Lower interest rates cut the other way, since most of Tether’s income is interest on US Treasury bills. And if a full audit, which the company says it is working toward, shows more or less surplus, the hard rows move with it.
