Tether’s 2-Year, $5 Billion Investment Blitz Fuels US Companies: CEO

Tether, the issuer of the USDT stablecoin, has quietly funneled roughly $5 billion of its earnings into a mix of US businesses and government debt over the past two years. It’s putting money where its mouth is.

According to CEO Paolo Ardoino, these moves are meant to show how tied the company is to the American economy, even as it dominates markets abroad.

According to Ardoino, Tether invested $775 million in Rumble earlier this year, scooping up more than 103 million shares of Class A stock. The firm also put $200 million into BlackRock Neurotech in 2024 through Tether Evo, its venture arm.

That move made Tether the majority owner of the brain‐interface startup. These aren’t small stakes. They’re big plays on what could be the next wave of tech growth in the US.

In the last 2 years Tether Group reinvested almost 5 billion USD of its profits within the United States economy and into US based companies. Some examples: Rumble, Blackrock Neurotech, XXI and different Bitcoin mining ventures.

Based on reports, Tether has also built positions in several US‐based Bitcoin mining firms. It recently boosted its holding in Bitdeer to 21%, making it one of the top shareholders.

On top of that, the company is routing hash power to the OCEAN pool, tying its crypto reserves even more directly to American mining operations. It’s a mix of finance and hardware.

According to filings, Tether holds more than $120 billion in US Treasury bills. That makes it the 19th‐largest holder of US debt, ahead of countries like Germany ($111 billion) and the United Arab Emirates ($104 billion).

These Treasury bills back most of the USDT in circulation. In a way, Tether has become a major player in the bond market, with a clear interest in keeping US fiscal matters steady.

Based on statements from Ardoino, Tether plans to launch a new dollar‐backed coin for the US market once federal rules are in place. While USDT will stay active in developing nations, a fresh token could meet upcoming US stablecoin laws.

With $153 billion in USDT out there—about 60% of the total stablecoin supply—Tether still leads globally. But in the US and Europe, USDT has seen some exchange delistings over MiCA compliance worries. A homegrown coin may smooth those relations.

Tether’s strategy isn’t without challenges. It faces calls for more transparency on its reserves and criticism over the use of USDT by bad actors. The company insists it works closely with law enforcement when criminal funds surface.
