Tether has about $4.8B in exposure to US stock markets

Tether, the world’s largest stablecoin issuer, holds about $4.8 billion of exposure to the US stock markets through 13 US-listed companies.

These entanglements include a controversial video-streaming platform that platforms right-wing influencers, royalties from gold mines, satellites, and a BTC treasury play.

Protos has reviewed regulatory filings in the US to better understand Tether’s links to these public markets.

Video-streaming for Donald Trump Jr.

Rumble (Nasdaq: RUM) is a video-streaming platform that partners with Donald Trump Jr. to stream his podcast, Triggered.

Tether has a 50.3% stake in Rumble, counting its warrants.

However, Tether doesn’t truly have control of Rumble, deliberately staying under 9.9% voting control.

RUM ($) fell from $5 (Oct 1, 2024) to $5 (Nov 10, 2026), down 2.1%, with a high of $16 (Dec 26, 2024).

Rumble also had previously acquired Tether-owned Northern Data.

This firm has started advertising itself as an “AI infrastructure and video company” as it widens its focus from just doing video streaming, effectively splitting itself in half (still under the RUM Group parent), with Rumble maintaining the video platform and Quake AI leading the cloud and AI business.

Tether is the most important purchaser of advertising from Rumble, according to Rumble’s 10-Q. According to the filing, “Tether has committed to provide advertising services of $50 million per year over a two-year period commencing February 16, 2026.

It also shows that, as of August, Rumble “recognized revenue of $6,730,859… for the six months ended June 30, 2026” related to this deal.

For quarter two, Rumble recognized $5.54 million from this Tether arrangement, representing approximately 14% of the $40.4 million in revenues for that quarter.

Tether is also one of the technology providers for the Rumble Wallet and some Rumble streamers have been advertising that if you sign up, you’ll receive “$10 in US Stablecoin (USAT).”

Bitcoin treasury

Tether is intimately tied in to BTC treasury firm Twenty One Capital (NYSE: XXI).

For one thing, Tether and Bitfinex became majority owners when they provided the BTC that got the firm off the ground.

It also had the right to nominate four of the seven board members for the firm. The four it chose were:

Paolo Ardoino, Tether’s CEO
Zachary Lyons, Tether’s CIO
Bo Hines, Tether US’ CEO
Raphael Zagury, CEO for Elektron Energy, a Tether-linked BTC mining operation

Zagury has subsequently been elevated to CEO for the firm following Jack Mallers’ departure.

This firm, which does little besides hold BTC, has often traded below the value of the asset.

Currently, it trades at approximately six-tenths of the value of its BTC.

What is it worth?

In total, Tether has approximately $4.8 billion in exposure to these public markets.

This is dominated by its role in a couple of the large firms, including Twenty One, Rumble, and Adecoagro.

This amount of value and the wide variety of firms in which it’s invested show the increasingly varied role that Tether has assigned itself.

Bar chart: Tether's stakes in US-listed firms are worth $4.8bn. Market value of each Tether stake at the Nov 9, 2026 close: latest filed share count × closing price; $4.8bn in all. Rumble includes pre-funded warrants. Data: SEC filings, Tiingo. Value ($) for 13 companies, Twenty One to Antalpha. Highest Twenty One at $1.4B; lowest Antalpha at $3.1M. — Chart of the value of Tether’s stakes.

It’s not solely issuing its dollar-pegged stablecoin; it’s using a wide variety of the funds it controls to invest across industries.

It also placed some of its executives, like Head of Special Projects Juan Sartori, into key roles at some of these firms.

Broadly, this review illustrates how critically important Tether is as a financial firm.
