Tether is building a Bitcoin Superstack beyond stablecoin dominance

Tether, the issuer of the USDT stablecoin, is strengthening its position as infrastructure for Bitcoin and the broader cryptocurrency market. Recently Bitcoin 2026 event In Las Vegas, Tether CEO Paolo Ardoino gave an inspiring keynote, invoking Isaac Asimov’s Foundation trilogy to describe Tether as building the long-term foundations of civilization through stablecoins, self-custodial wallets, Lightning Network optimization, and Bitcoin vault management. The announcements included confirmation of Tether holding more than 140,000 bitcoins, a proposed game-changing merger between Twenty One Capital (XXI), Strike and Electron Energy, and new resources such as a new Bitcoin tether.wallet faucet to encourage self-custody.

These announcements come at a time when there is strong evidence that stablecoins have crossed the limits of speculation.

What is Tether and why is it important?

Tether is a blockchain-based stablecoin launched in 2014. USDT aims to remain pegged to the US dollar on a 1:1 basis by holding tokens in reserve assets such as cash, treasury bills, gold, and bitcoin.

USDT is now the world’s largest stablecoin and one of the most traded crypto assets. It has a market capitalization of approximately US$189 billion as of 2026 with a daily trading volume of over US$121 billion. USDT has a market share of 59% In the stablecoin market, which exceeds $320 billion.

The stablecoin works as follows:

• A bridge between cryptocurrency exchanges
• Hedging against volatility
• Hedging against inflation in developing countries
• Payment and remittance infrastructure
• Settlement layer for cryptocurrency trading

Real economy payments in stablecoins will reach $350-$550 billion in 2025

The conventional wisdom that stablecoins are mainly used for trading cryptocurrencies is changing.

Onchain Analyst Highlighted by Leon Weidmann The numbers show that real stablecoin payments in the real economy grew to $350-550 billion in 2025, up 55% year-on-year and after adjusting for trading, treasury and other inorganic activities.

The majority of B2B payments were between $150 and $230 billion, up 65%. Consumer-to-business (C2B) transactions were $90-130 billion, up 55%, and consumer-to-consumer (C2C) payments were also $90-130 billion, up 75%. Business-to-consumer (B2C) payments reached $20 to $60 billion, an increase of 50%.

All sectors grew by more than 50%, with the B2B sector remaining the largest and fastest growing sector. The largest stablecoin, Tether (USDT), with approximately 58% market share, continues to play a pivotal role in facilitating these growing payment flows.

Tether is building a multi-layered treasury worth 140,000 BTC that bypasses public tracking

During the Bitcoin 2026 event, revealed Paolo Ardoino, CEO of Tether The company owns more than 140,000 BTC. The news immediately caught the attention of on-chain analysts, with public data from Arkham Intelligence revealing that Tether currently only holds around 97,204 bitcoins.

This leaves a huge gap of about 43,000 BTC. Market analysts believe this discrepancy is likely due to Tether’s complex custody and procurement practices, which focus on security and preventing market manipulation rather than full on-chain transparency.

Possible explanations include:

• Bitcoins held by institutional partners such as BitGo or others at dedicated, undisclosed addresses.
• Bitcoins are purchased through over-the-counter (OTC) brokers, and are held in new, segregated, or newly labeled wallets to limit the market impact of large transactions.
• Bitcoin has been allocated to Tether’s growing mining business and has not yet been added to the underlying treasury accounts monitored by analytical platforms.

Through various custodial practices, Tether will likely accumulate a large and robust reserve of Bitcoin to meet its long-term strategic reporting needs rather than its short-term reporting needs.

Tether proposes a historic merger to create a vertically integrated Bitcoin giant

Tether Investments has officially proposed a Triple merger Between Twenty One Capital (XXI), Strike and Elektron Energy in a vertically integrated Bitcoin powerhouse. The plan, announced on April 29, 2026, seeks to transform XXI from a treasury-only holding company into the world’s leading “bitcoin operator.”

Business Model: 21st vs. Micro Strategy (MSTR)

While MicroStrategy (MSTR) created a “leveraged treasury” model using debt to steal money, the proposed 21st entity would be a cash flow machine. Tether’s announcement emphasizes that this merger will take XXI “beyond treasury exposure alone” to a recurring revenue model.

• Integrated revenue: Instead of building a negative MSTR for BTC, XXI will integrate Strike’s global payment network (operating in over 100 countries) with Elektron’s massive mining fleet (currently 50 EH/s, or about 5% of the global network’s hash rate).
• Synergy: Under the direction of Jacques Muellers (CEO) and Rafael Zagori (President), the entity will use its healthy balance sheet to provide lending, capital markets and payments services, building a sustainable ecosystem rather than just a BTC price proxy.

This integrated model means that XXI will be able to leverage the entire Bitcoin supply chain – mining for global payments.

Strike Unveils $2.1 Billion Credit Facility for Volatile Bitcoin Loans

Jack Mallers, CEO of Strike, recently announced $2.1 billion Tether-backed credit facility To support Bitcoin-backed lending businesses.

This facility gives Strike a large pool of financing for high loan demand with no size limits. Prices have been adjusted in tiered pricing of 10.5% APR for loans under $250,000 and 7.49% APR for loans over $5 million.

Another feature is “volatility-resistant” Bitcoin-backed loans, in partnership with pregnancy. Other cryptocurrency loans tend to be vulnerable to liquidation during price declines. Strike’s iteration of the loan seeks to eliminate or reduce this risk – reportedly, through a voluntary premium to protect against liquidation regardless of the price of bitcoin.

In order to enhance transparency, Strike has launched the first version of proof of its lending reserves. This allows borrowers to ensure that the Bitcoin they deposit is kept in separate on-chain addresses and is not re-mortgaged. The company will update quarterly with audits.

These developments provide Strike’s lending group with greater borrower protection, while also enhancing its integration with Tether’s underlying infrastructure.

conclusion

These latest developments show that Tether is overtaking its stablecoin asset to become a major player in the Bitcoin infrastructure. Tether is building an integrated financial services infrastructure around Bitcoin, including growing its BTC treasury and providing support for large-scale mining, global payments, and loans backed by Bitcoin.
