Estimate Puts Tether’s Exposure to U.S. Stocks at $4.8 Billion Across 13 Companies
Key Facts
Protos estimated Tether’s exposure to shares of U.S.-listed companies at about $4.8 billion across 13 companies, based on a review of U.S. regulatory disclosures. The estimate was published in November 2026 and reflects a compilation of holdings reported in official filings, priced at the close on November 9. Tether has not announced this total as a unified portfolio, and the estimate was not presented as a company disclosure. The figure is therefore a journalistic tally of estimated exposure to listed shares, not an official statement about an investment portfolio or its purpose. Rumble stands out among the largest positions in the tally, alongside a concentration of much of the value in a limited number of companies.
A Schedule 13D filing with the U.S. Securities and Exchange Commission shows Tether Investments holds a 50.3% beneficial economic interest in Rumble when shares and warrants are included. The figure reflects beneficial ownership as reported in the filing, but is not equivalent to the percentage of voting rights held by the company. Protos said Tether keeps its voting rights below 9.9%, even as the inclusion of warrants raises its economic stake to more than half the company. These figures distinguish the size of the economic interest from the ability to vote, two different aspects of company ownership. The filing is based on shares and warrants outstanding as of August 6, 2026, including 119,607,981 prepaid warrants exercisable for Class A shares.
RUM Group filings show a parallel commercial relationship between the two parties alongside the investment. The group disclosed to the Securities and Exchange Commission that Tether committed to buying $50 million in advertising services annually for two years, starting February 16, 2026. The agreement links Tether and the Rumble platform through advertising spending with a specified duration and value. The group’s figures show Rumble advertising revenue of $17,319,209 in the third quarter of 2026, compared with $11,730,859 in the third quarter of 2025. The figures place the agreement within an advertising business that recorded year-on-year growth, without on their own specifying the impact of Tether’s commitment on reported revenue.
RUM Group recorded total revenue of $96,577,752 in the three months ended September 30, 2026, compared with $24,762,445 in the corresponding period of 2025. The group said revenue growth included a contribution from Quake AI following its acquisition of Northern Data. The comparison provides context for the company’s performance in the quarter before the Tether exposure estimate was published, but does not measure the value of Tether’s stake or its return on the investment. Revenue data relate to the group, while the ownership filing focuses on Tether’s stake in Rumble. The estimated $4.8 billion figure comes from aggregating positions in 13 companies, not from a unified valuation announced by Tether.
