Tether

IWhat it does

Tether Holdings is not publicly traded. It is privately owned, it has not filed to list, and it has not published audited financial statements. Everything below is research on a private company, not investment advice.

Tether issues USDT, a token that is meant to be worth one US dollar. A holder can move it across blockchains in seconds. Tether says it can be redeemed for dollars. The company backs the tokens with reserve assets, mostly short-term US government debt. At 30 September 2026 it reported about $184 billion of USDT in issue, held steady through the first three quarters of the year¹. That makes it the largest dollar stablecoin by a wide margin.

The product is simple. The reason it matters is where it is used. In mid-October 2026, DefiLlama data cited by a French outlet put USDT at about $183.5 billion, or roughly 60% of the roughly $306 billion dollar-stablecoin market, against about $72.6 billion for Circle’s USDC¹⁷. Tether’s chief executive says the user base passed 650 million people⁹. That is a company claim and I have not seen it verified. In many countries with weak currencies or capital controls, USDT works as a way to hold dollars without a US bank account. That is the demand behind the business.

Tether also runs side businesses funded from its profits. Its own news page in the last week of October 2026 shows a bitcoin-mining software kit, a foundation to fight online scams, and compliance work with law enforcement²³. The 2025 and 2026 fundraising talks described a plan to expand into AI, commodity trading, energy, communications and media¹³. These are plans and investments, not reported revenue lines, so I do not model them.

IIHow it makes money

The model is the float. A holder gives Tether a dollar and gets a token. Tether invests the dollar in Treasury bills and keeps the interest. It pays no interest to token holders. With about $184 billion in issue and short rates near 3.5%, the interest alone is large. At the rate Circle reports earning on its own reserves, 3.5%⁶, the $132.4 billion in bills would earn about $4.6 billion a year. That is my estimate, not a reported figure. Tether’s reported net operating profit runs at about $6 billion a year ($1.5 billion a quarter)¹, so the remainder presumably comes from its other assets, such as the loans and equity stakes in its reserve pool. Tether does not break this down in the pages I could read.

Costs look low. Circle, the nearest public comparison, reported $668 million of reserve income in Q2 2026 and $410 million of distribution and transaction costs, which is the cost of getting USDC distributed and processed⁶. That is about 61% of reserve income. I cannot see an equivalent payout in Tether’s reports, and the attestations are not income statements, so I cannot say how much Tether pays out. If Tether pays far less than Circle, it is because USDT is the default token on most exchanges and does not need to buy distribution.

Two cautions on reading the profit. First, Tether now leads with net operating profit, which leaves out unrealised gains and losses on assets like gold and bitcoin⁹. Including them, The Block reports a first-half 2026 result that was a $3.2 billion loss⁹. Second, the 2025 headline of more than $10 billion is described as net profit¹⁰, so it is not the same measure as 2026’s $4.5 billion for nine months. Do not stack the two on one line.

A final point on sensitivity. Income follows short-term interest rates. By my arithmetic, each one percentage point fall in yield on $184 billion of reserves removes about $1.8 billion a year before costs. A world of falling rates and flat supply is the central earnings risk.

Reported and press-reported figures behind the earnings. Reported means Tether published it; press-reported means a news outlet gave it and Tether’s page did not.

IIIThe market and the competition

Stablecoins are tokens pegged to a currency. In mid-October 2026 the dollar-pegged group totalled about $306 billion: USDT $183.5 billion (about 60%), USDC $72.6 billion (about 24%), and the rest about $49.9 billion¹⁷. Those shares come from a secondary source quoting DefiLlama, and the totals move daily.

Circle is the main rival. It is listed in New York. At the 2 November 2026 close its market value was $18.39 billion and its enterprise value $16.67 billion, with a trailing price-to-earnings ratio of about 40 and EV/revenue of 5.7²¹. Its Q2 2026 net income from continuing operations was $48 million on $701 million of revenue, with USDC at $73.3 billion⁶. It reports Q3 on 4 November 2026⁷. Coinbase, a large exchange with a USDC relationship, trades at a market value of $36.49 billion and 6.35 times revenue²². Banks, payment firms and the wider fintech industry are also building dollar tokens, but I only checked Circle and the US-regulated Tether product (below).

Two rule sets are splitting the market. In Europe, MiCA (the EU’s crypto-asset law) requires issuers of tokens pegged to one currency to be authorised. Tether has not been, and USDT has been removed from regulated European platforms. Revolut, for example, stopped USDT purchases on 6 July 2026 and fully delisted it on 31 August 2026 for customers in the European Economic Area and Switzerland¹⁶. A French outlet reports that the EU markets authority, ESMA, issued an opinion on 8 October 2026 asking licensed providers to stop services on non-compliant stablecoins, with a platform deadline of 8 January 2027¹⁷. I could not confirm that opinion on ESMA’s news page²³, so treat it as unverified.

In the United States, the GENIUS Act, signed in 2025, sets a federal framework for payment stablecoins. Treasury proposed a rule on 18 August 2026, with comments closing on 19 October¹⁵. Davis Polk reports that Treasury has not found any foreign regime comparable and has not proposed how it would decide¹⁴. Dates reported: 18 January 2027, when platforms must not offer a foreign-issued stablecoin unless the issuer can comply with lawful orders; and 18 July 2028, when platforms may not offer stablecoins from non-qualifying foreign issuers to US persons¹⁴¹⁵. Tether’s answer to this is USAT, a separate token issued by Anchorage Digital Bank, a federally chartered national bank, not by Tether¹⁹. Anchorage’s first attestation showed $17.6 million of reserves backing 17.5 million USAT at 31 January 2026¹⁹. It is tiny next to USDT. I did not find a reliable current figure for USAT supply.

IVThe moat and how it could be disrupted

Tether’s advantage is liquidity and habit. A stablecoin is useful in proportion to how many places accept it. USDT is the quote currency for much of crypto trading, it circulates on many blockchains, and it has deep trading pairs. A new token must be accepted by exchanges, wallets and counterparties before anyone wants to hold it. That is a network effect, and it has held through a long record of regulatory and credibility problems, including a 2021 CFTC finding that Tether misstated its reserves⁴.

The second advantage is cost. If, as I infer, Tether does not pay for distribution at anything near Circle’s 61% of reserve income⁶, it keeps more of each interest dollar. That is only an inference, because Tether does not publish an income statement.

The moat has weaknesses I would not wave away. First, it is narrower in the places with the most regulation. USDT is off regulated European platforms¹⁶ and has an uncertain path in the United States¹⁴. Second, the moat is not a contract. A user can swap USDT for another dollar token in seconds, and exchanges can change which token is the default. Third, the business depends on trust in assets Tether does not let anyone audit. S&P Global lowered its stability assessment of USDT to weak, its lowest category, on 26 November 2025, citing a rise in riskier reserve assets, limited information on custodians and counterparties, and the lack of a robust regulatory framework¹⁸. Tether strongly disagreed¹⁸. Fourth, a rival can be paid to win: Circle pays heavily for distribution⁶, so a well-funded bank or payments group could subsidise a competing token.

The view is therefore divided. The peg has held, redemptions have been processed, and share is about 60%¹⁷. Yet most of what keeps it there is custom, not law. I rate it contestable, towards the top of that band: real, valuable advantages, but not durable if regulated rivals or a reserve problem erode trust. A credible challenger already exists, which is why I do not use the next level up.

VThe numbers we can see

Tether publishes a quarterly report prepared by BDO under the international standard ISAE 3000R, a form of assurance on stated figures¹. It is not an audit of financial statements. The report is the main public evidence for the reserves. I could not open the BDO PDF itself, because the file is encrypted. Everything here comes from Tether’s release and press accounts of it, and I could not check the opinion wording.

What Tether reports at 30 September 2026: total assets of $191,451,091,374, total liabilities of $183,496,460,904, and excess reserves of $7,954,630,470. Treasury bills, direct and indirect, are $132.4 billion¹. Press accounts add a breakdown of about $19.1 billion in precious metals, $8.4 billion in bitcoin, $4.2 billion in listed equities, $14.2 billion in secured loans and about $6 billion in other investments⁸. That article says the lines do not reconcile to total assets. I add them to about $184.2 billion, so about $7 billion is missing from the picture. Treat this breakdown as partial and press-reported.

Bitcoin is a good example of the gaps. The Block gives $5.8 billion of bitcoin at 30 June 2026, down from $6.6 billion at the end of March⁹. The Q3 press figure is $8.4 billion⁸. A rise of $2.6 billion in a quarter is a big move, and I cannot tell from these sources whether it came from buying or from price. The sources conflict or are silent, so I do not explain it.

The profit does not map to the buffer. From the end of 2025 to the end of September 2026 the buffer rose from $6.3 billion to $7.95 billion, an increase of about $1.65 billion¹⁰¹. Over the same nine months Tether reports $4.5 billion of net operating profit¹. By my arithmetic, about $2.9 billion is unaccounted for. It could be price losses on gold and bitcoin⁹, payments to owners, or other items. In Q2 alone the buffer fell $4.1 billion in a quarter with $1.5 billion of operating profit⁹, which implies about $5.6 billion of other reductions that Tether did not explain in the material I read. In Q3 the buffer rose $3.85 billion with $1.5 billion of profit, which implies about $2.3 billion of other gains. All three are my estimates.

What I can say is that about $7.95 billion of cushion sits under $184 billion of tokens, a margin of about 4.3% of liabilities. If the risk assets, which the press reports at about $50 billion if loans, metals, bitcoin and equities are added, lost 16% of their value with no offset, the buffer would be gone. That is my arithmetic on press-reported figures, not a forecast.

Excess reserves (assets minus liabilities) by quarter-end. The measure is the same at each date. Net operating profit is shown for contrast and is not the same measure.

VIWho runs it and who owns it

Paolo Ardoino is chief executive. His promotion from chief technology officer was announced in October 2023 and took effect that December²⁷. Giancarlo Devasini is chairman, and Simon McWilliams became chief financial officer in March 2025²⁴. Bo Hines was named as the future chief executive of the US business, Tether USAT, in September 2025²⁵.

Tether is closely held. The New York Attorney General found that Bitfinex and Tether are owned and operated by a small group of executives and shareholders located around the world²⁰. I found no filing that states who owns what, so I do not give ownership percentages. The funding talks reported a sale of about 3% of the company¹³, which says the current owners keep nearly all of it. An outside investor has no say in how profits are paid out or invested.

The record matters for trust. In 2021 the New York Attorney General found that Tether had at times held no reserves backing tokens one for one, and that Bitfinex had lost about $850 million through a payments intermediary and did not disclose it. Bitfinex and Tether paid $18.5 million and agreed to disclose reserves by category⁵. In October 2021 the CFTC ordered Tether to pay $41 million, finding that from 2016 to early 2019 it misrepresented that its tokens were fully backed by dollars. In a 26-month sample, reserves covered the tokens on only 27.6% of days⁴. Neither order is about the company’s current reserves, and in the New York settlement Tether and Bitfinex neither admitted nor denied the Attorney General’s findings²⁰. I mention them because an owner or lender would weigh them.

VIIValuation: is the last price supported?

Equity value in US$ billions. Not a share price: a private company has none. Latest mark: press-reported target for a private placement that has not been reported as closed; not a priced round.

What the last valuation assumes

At $500 billion, the price is about 83 times Tether’s annualised operating profit of $6 billion¹ and about 50 times the more than $10 billion reported for 2025¹⁰. In my model it needs supply near $825 billion in five years (about 35% a year growth), yields held near 3.5%, and a multiple of roughly 35 to 40 times, all at once. A 40x multiple on my base case gives about $140 billion, so even a Circle-style multiple does not get there without very fast growth. The figure is a negotiating target in a raise that Tether sought to close: floated at 15 to 20 billion of new equity for about 3%¹³, scaled back to about 5 billion in February 2026 amid investor resistance¹¹, then pushed again in April 2026 with a two-week deadline¹². I found no report that it closed.

Bear, base and bull

• Bear. USDT supply falls 2% a year from $184 billion to about $166 billion by 2031. Yield on reserves averages 2.0%, margin after costs and mark losses 75%. Earnings about $2.5 billion in 2031. Terminal multiple 7 times earnings, discount rate 18%, 50% of earnings paid out, no dilution. Reflects loss of US and EU access, share loss to regulated rivals and lower rates. The model gives $11.7 billion, rounded to 12.
• Base. Supply grows 5.5% a year to about $240 billion by 2031. Yield 3.25%, margin 85%, so 2031 earnings are about $6.6 billion, close to today’s annualised $6 billion¹. 60% of earnings are distributable. Terminal multiple 12 times, below Circle’s 40 trailing P/E²¹ because Tether is unaudited, rate-sensitive, and shut out of the EU¹⁶. Discount rate 15%: a risk-free rate near 4% plus roughly 11 points for reserve opacity, regulatory and key-person risk (my judgement). Dilution 3%, matching the reported size of the proposed raise¹³. Model result $50.0 billion.
• Bull. Supply grows 17% a year to about $400 billion by 2031 on emerging-market demand and a US route. Yield 3.5%, margin 90%, 2031 earnings about $12.7 billion. 70% payout. Terminal multiple 20 times, which is still half of Circle’s trailing multiple²¹. Discount rate 12%, dilution 3%. Model result $162.4 billion.

Comparables used

Where I come down

The $500 billion figure is far above my base case of $50 billion, and above my bull case of $162 billion. It is stale: the latest report I found is from April 2026¹², and it is a target, not a price anyone paid. For it to be right you would have to believe that USDT can reach several times its current size while keeping margins, that rates stay high, that the US and EU accept it, and that its reserves hold under stress. The case for the market being right: Tether earns real money ($1.5 billion a quarter by its own count¹), has a record of holding the peg, and could be worth more to a strategic buyer than its earnings alone, for example for distribution or control of a payment rail. A buyer may also value the option to expand into other businesses¹³. I give that little weight because those businesses have no reported revenue. The margin of safety figure of $38 billion is my base less 25%.

What I cannot judge

I cannot judge the true quality of the reserves. Tether publishes assurance reports, not audited statements, and I could not open the BDO PDF. I cannot reconcile profit to the buffer (about $2.9 billion gap over nine months) or the press-reported asset breakdown, which does not add up to total assets. I do not know what Tether pays to distribute USDT, who owns what share, or how much the owners have taken out. I could not confirm the reported 8 October 2026 ESMA opinion. Web search access ran out during my research, so I could not check for news after the sources dated here. The valuation range is wide on purpose: $12 billion to $162 billion.

VIIIThe IPO

No IPO plan reported. I found no report of an IPO filing or of banks hired. The only capital-raising reported is a private placement of about 3% at a target of $500 billion, which was floated in September 2025¹³, scaled back to about $5 billion in February 2026¹¹ and pushed again in April 2026¹². I found no report that it closed. Tether’s own news page for late October 2026 mentions no raise². Circle (NYSE: CRCL) is the listed comparison and reports Q3 on 4 November 2026⁷.

What to watch

• Whether a private round closes, with a named investor and price.
• The first audited financial statements from a large accounting firm (a pending Big Four audit has been reported in the press, which I could not confirm).
• Treasury’s final rule, and any comparability finding for Tether’s home regime, before 18 January 2027 and 18 July 2028¹⁴.
• ESMA or national regulators’ actions after the reported 8 October 2026 opinion¹⁷.
• The quarterly buffer and its explanation: whether excess reserves keep rising¹.
• USAT supply, now only $17.6 million at first attestation¹⁹.
• Circle’s Q3 results on 4 November 2026 for rate and distribution trends⁷.

IXWhat could go wrong

What most likely destroys this business is a loss of trust in the reserves that leads to fast redemptions, at a time when part of the reserves is in assets that are not instant cash. About $132 billion of the assets are Treasury bills and repos¹, which can be sold fast. The rest cannot necessarily be sold quickly at a fair price. The buffer is $7.95 billion¹. A large fall in bitcoin, gold or loan values, or a run, tests that margin.

Second, rates. Lower short-term interest rates cut earnings roughly in line with yield, as above. Third, regulation. The US route for foreign issuers depends on a comparability finding that Treasury has not made¹⁴. EU access is shut for regulated platforms¹⁶. A US platform ban from July 2028 would remove a large pool of buyers if Tether is not eligible¹⁴.

Fourth, owner extraction. An outside buyer of equity could take out only what Tether chooses to pay. The company reports an operating profit but also shows a buffer that moves by billions for reasons not disclosed. The cash an owner can really take is the interest after losses, less what is needed to keep the buffer thick enough that the market does not worry. I assume 50% to 70% of earnings are distributable in my cases, not 100%.

Fifth, what has to go right together for a $500 billion price. In my model it needs supply to grow about 35% a year for five years (to roughly $825 billion), yields to stay near 3.5%, no reserve scare, Treasury and OCC access, and a multiple above 35 times earnings. If I put each of those at, say, a one in two chance and they are roughly independent, the joint chance is about three percent or lower. That is my rough judgement, not a measured probability.

Sixth, the next best alternative for the same dollar. Circle trades at about 40 times trailing earnings and $18.4 billion market value²¹, and is regulated and audited. A buyer of Tether at $500 billion pays about 83 times annualised operating profit of $6 billion¹, or about 50 times the $10 billion reported for 2025¹⁰. A public, audited rival at a lower multiple is the standard comparison.

Other risks: sanctions and law-enforcement exposure, since USDT is used by illicit actors and Tether says it works with more than 360 agencies in 73 countries and has frozen over $1.5 billion tied to the 29 October 2026 Binance attack³ (company claims); key-person risk; and ownership opacity.
