Tether beyond USDT: Where the company is investing billions

​Tether built the world's largest stablecoin by taking a different path from much of the financial industry. It has since applied the same approach to regulation, investment and expansion far beyond crypto. The bigger question now is: how far can that strategy stretch?

The answer matters because Tether is no longer simply the company behind USDT. Flush with billions of dollars in profits, it has invested in energy, Bitcoin mining, agriculture, artificial intelligence, telecommunications and other businesses. Uruguay was supposed to become part of that expansion, but the project instead ended in a costly dispute.

Tether entered the country in 2023, attracted by its renewable energy resources and plans to build a broader mining presence in Latin America. Two mining sites were eventually disconnected after a dispute with state-owned utility UTE over their electricity contracts and unpaid bills. The failed project cost Tether roughly $120 million, according to people familiar with the operation.

But we saved everything 🙂.

The loss is small compared with Tether's earnings. What makes it significant is what it says about a company increasingly willing to make large bets far outside the business that made it successful.

Why did Tether choose a different path in Europe?

The Uruguay setback follows another unconventional strategic decision. When the European Union introduced its Markets in Crypto-Assets regulation, Tether chose not to seek authorization for USDT, objecting in particular to requirements governing stablecoin reserves. Circle took the opposite approach, securing authorization for USDC as regulated European platforms increasingly restricted USDT.

Yet Tether has not abandoned Europe. It invested in European stablecoin issuer StablR, while its Hadron tokenization platform has been used by regulated Dutch issuer Quantoz. Nor has staying outside MiCA seriously weakened USDT so far.

By the end of June, USDT issuance had reached roughly $184.6 billion, while Tether reported $1.5 billion in second-quarter operating profit and a $4.11 billion reserve buffer. This month also brought a long-awaited milestone: KPMG U.S. completed Tether's first full financial statement audit and issued an unqualified opinion on its 2025 accounts.

Stablecoin profits created a very different company

Tether's success has given it an unusual problem: what to do with the money it earns. Increasingly, the answer has been investment.

Its interests now span Bitcoin mining, renewable energy, artificial intelligence, telecommunications, agriculture and other industries. Mining in particular has become a substantial operation, with Tether now reporting more than 15 active sites.

Tether has made much bigger claims about its mining ambitions before. In June 2025, CEO Paolo Ardoino predicted that the company would become the world's largest Bitcoin miner by the end of that year.

“Realistically, by the end of this year, Tether will become the biggest bitcoin miner out there,” Ardoino said.

There is no public evidence that Tether reached that target. The company does not disclose enough about its mining hashrate for a direct comparison with the largest operators and has made no subsequent claim that it took the top position. A month after Ardoino's prediction, UTE disconnected Tether's two mining facilities in Uruguay.

Uruguay shows what diversification can cost

The immediate problem was electricity. Tether and UTE disagreed over how much power the facilities were entitled to receive, with the company seeking additional capacity while the utility treated the contracted amounts as limits. Payments stopped as the dispute escalated, and most local employees were eventually laid off.

There may also have been a more fundamental problem with the location. Uruguay has a largely renewable and reliable electricity system, but Bitcoin mining depends heavily on obtaining power cheaply enough to remain profitable.

Mining specialist Nicolas Ribeiro put it bluntly: “Uruguay isn't viable for mining.”

The episode illustrates a broader problem with diversification. Expertise in digital dollars does not automatically translate into expertise in electricity contracts, energy infrastructure or industrial operations.

Tether is still betting on expansion

Bitcoin mining remains part of those ambitions. In April, the company unveiled new modular systems developed with Canaan and ACME Swisstech, designed to improve control over energy use, cooling and operating costs.

The company is pushing into other areas as well. This month, Tether announced a Saudi Arabian partnership using its Hadron platform for institutional real-estate tokenization. It has also continued building businesses around artificial intelligence, gold and other areas far removed from the stablecoin with which it made its name.

Some of those businesses fit together more naturally than others. Energy can support mining, while payments and tokenization remain close to Tether's original expertise. Artificial intelligence, agriculture and other investments take it considerably further away.

Can Tether's success travel beyond stablecoins?

There is little evidence yet that rejecting MiCA or expanding beyond stablecoins has weakened Tether's main business. USDT remains dominant, profits remain substantial and a $120 million loss is manageable for a company operating at Tether's scale.

As the portfolio expands, however, Tether increasingly resembles a privately controlled investment group whose enormously profitable stablecoin business provides the capital for ventures across multiple industries. Success in those businesses requires skills that issuing USDT does not necessarily provide.

Having the money to enter an industry and knowing how to succeed in it are two different things. As Tether's ambitions expand, the question is increasingly whether the company can invest its billions as successfully as it has generated them.
