Tether has built an estimated $4.8 billion portfolio spanning 13 U.S.-listed companies, according to a Protos review of SEC filings. The positions reach well beyond the issuer’s core USDT stablecoin business and extend into bitcoin treasury vehicles, online video and AI infrastructure, precious metals, agriculture, mining and satellite imaging.
The reported holdings suggest Tether is deploying capital from its broader business into a wide mix of operating companies and financial exposures. While USDT remains central to the company, the portfolio described in the filings points to a much broader investment footprint.
Largest positions are Twenty One Capital and Rumble
The biggest disclosed holding is Twenty One Capital, which Protos valued at about $1.37 billion. Tether and Bitfinex became majority owners after contributing bitcoin to launch the company, and Tether received the right to nominate four of the company’s seven directors.
The report said Twenty One’s shares trade at only about 57% of the value of its 43,514 BTC holdings, highlighting the discount public investors have applied to some crypto treasury businesses. Tether’s second-largest position is in Rumble, with an estimated value of about $1.33 billion.
Including warrants, Tether’s economic interest in Rumble is reported at 50.3%, though its voting control remains below 9.9%. That split underscores how the company’s financial exposure does not necessarily translate into matching control rights.
Gold-related holdings form a major part of the portfolio
A significant part of the portfolio is tied to precious metals. The companies named in the report include Elemental Royalty, Gold.com, Versamet Royalties, Metalla Royalty & Streaming and Gold Royalty.
Tether also holds stakes in Aurelion and Antalpha, which the report described as linked to Tether Gold. In one notable disclosure, Gold.com said it generated $1.2 billion in fiscal 2026 revenue from business with Tether, and that Tether represented more than 25% of its revenue in a recent quarter.
Reach extends into mining, agriculture and satellites
Outside crypto treasury and gold-related positions, the reported holdings also include Bitdeer for bitcoin mining exposure, Adecoagro for agriculture and energy, and Satellogic for satellite imaging. Taken together, the spread of investments resembles a portfolio built across multiple industrial and financial themes rather than a narrow crypto strategy.
Protos said performance across the holdings has been mixed. Twenty One has fallen roughly 53% since listing, while Antalpha has dropped about 90% since its market debut. At the same time, Metalla and several gold-royalty investments have posted substantial gains over the periods tracked.
What the filings suggest about Tether’s direction
The filings reviewed by Protos also indicate that Tether executives hold influential positions across parts of this network of companies. That pattern, combined with the size and variety of the stakes, has led observers to describe Tether as increasingly resembling a diversified investment and industrial holding company.
The next confirmed reference point for judging that strategy will be future corporate and regulatory filings that show whether these positions grow, shrink or change in structure. For now, the available SEC disclosures point to a company still anchored by USDT but increasingly active across a much wider set of sectors.
