Tether Builds Bitcoin Superstack Beyond Stablecoin Dominance

Tether, which launched the USDT stablecoin, is solidifying its position as the foundation of Bitcoin and the cryptocurrency market. Recently Bitcoin Event 2026 in Las Vegas, Tether CEO Paolo Ardoino gave an encouraging speech, evoking Isaac Asimov’s Foundation trilogy describing Tether as building the foundation for long-term development through stablecoins, self-control wallets, Lightning Network optimization, and Bitcoin asset management. Announcements included the confirmation of Tether holding > 140,000 BTC, the game-changing partnership of Twenty One Capital (XXI), Strike and Elektron Energy and innovations such as the tether.wallet Bitcoin faucet to promote self-confidence.

These announcements come at a time when there is strong evidence that stablecoins have gone beyond speculation.

What is Tether and Why is it Important?

Tether is a blockchain-based stablecoin that was launched in 2014. USDT aims to remain pegged to the US dollar at 1:1 by storing tokens in escrows such as cash, Treasury bills, gold and Bitcoin.

USDT is now the world’s largest stablecoin and one of the most traded cryptocurrencies. It has a market cap of about $189 billion as of 2026 with daily sales of over $121 billion. USDT has a market share of 59%. in the stablecoin market, which is over $320 billion.

Stablecoin works like this:

• A bridge between cryptocurrency exchanges
• A hedge against volatility
• Rising inflation in developing countries
• Shipping and handling fees
• A regular part of crypto trading

Stablecoin Real-Economy Fees Hit $350-550B in 2025

The conventional wisdom that stablecoins are primarily used for cryptocurrency trading is changing.

Onchain expert Leon Waidmann emphasized Statistics show that stablecoin real payments in the real economy have grown to $ 350-550 billion in 2025, up to 55% year-on-year and after changes in trade, economy and other non-organic activities.

Most of those payments were business-to-business (B2B) with a revenue of $150-230 billion, up 65%. Consumer-to-business (C2B) transactions were $90-130 billion, up 55%, and consumer-to-consumer (C2C) transactions were also between $90-130 billion, up 75%. Business-to-consumer (B2C) payments totaled $20-60 billion, up 50%.

All sectors grew by more than 50%, while B2B remained the largest and fastest growing sector. The largest stablecoin, Tether (USDT), with a market share of around 58%, continues to play an important role in managing the growing payment system.

Tether Builds Multi-Layered 140,000 BTC Treasury Beyond Public Tracking

At the Bitcoin 2026 event, Tether CEO Paolo Ardoino revealed that the company is holding on 140,000 BTC. The news immediately caught the attention of on-chain researchers, with public data on Arkham Intelligence revealing that Tether currently has only 97,204 BTC.

This leaves a huge gap of about 43,000 BTC. Market analysts believe that the discrepancy is due to Tether’s difficulties in storing and purchasing assets, which focus more on security and avoiding market manipulation than transparency on the chain.

Possible explanations include:

• Bitcoins are held in custody by organizations such as BitGo or others that have dedicated, non-public addresses.
• Bitcoin is bought through Over-the-Counter (OTC) transactions, which are kept in new, separate or newly listed wallets to reduce the market’s sensitivity to large transactions.
• Bitcoin given to the growing Tether mining business that is supposed to be added to Treasury accounts that are monitored by monitoring platforms.

Through its various storage systems, Tether is supposed to accumulate large and stable Bitcoins over the long term rather than needing to report short-term.

Tether Seeks Landmark Merger to Create Vertically Integrated Bitcoin Giant

Tether Investments has arranged that a plus three between Twenty One Capital (XXI), Strike, and Elektron Energy to become a combined Bitcoin powerhouse. The plan, which was announced on April 29 2026, aims to change XXI from a financial-only company to “Bitcoin” which leads the world.

Business Type: XXI vs. MicroStrategy (MSTR)

While MicroStrategy (MSTR) implemented a “leveraged treasury” model using debt for pilfer sats, the proposed XXI entity will be a cash flow machine. Tether’s announcement emphasizes that this integration will take XXI “beyond the transparency of the economy itself” to the way of lending money.

• Total Fees: Instead of building only a small MSTR for BTC, XXI will combine Strike’s global payment system (working in more than 100 countries) and Elektron’s large mining fleet (currently 50 EH/s, or about 5% of the global hashrate).
• Synergy: Headed by Jack Mallers (CEO) and Raphael Zagury (President), the organization will use its normal capital to provide credit, capital markets and payment services, building a sustainable ecosystem instead of just taking the value of BTC.

This integrated model means that XXI will benefit from all aspects of Bitcoin – mining to international payments.

Strike Reveals $2.1 Billion in Unsettled BTC Loans

Jack Mallers, CEO of Strike, recently announced a $2.1 billion of Tether-backed debt to support his Bitcoin lending business.

This facility provides Strike with a large pool to support its credit needs without limits. Rates are adjusted for rates of 10.5% APR for loans under $250,000 and 7.49% APR for loans over $5 million.

Another thing is “volatility-proof” Bitcoin-backed loans, according to Tether. Some crypto loans tend to be at risk of defaulting on devaluations. Strike’s iteration of the loan aims to eliminate or reduce this risk – it is said to use voluntary funds to protect against liquidation regardless of the price of Bitcoin.

In order to promote transparency, Strike launched the first type of proof of rent. This allows borrowers to ensure that the Bitcoin they deposit is stored in separate, off-chain addresses and not duplicated. The company will update quarterly with audits.

These developments provide greater protection for Strike borrowers, and further enhance its integration with Tether’s infrastructure.

The end

These recent developments show that Tether is growing beyond its stablecoin origins to become a player among Bitcoin. Tether is building the financial infrastructure around Bitcoin, including expanding its BTC economy and supporting large-scale mining, global payments and Bitcoin-backed loans.
