Twenty One Capital, the investment vehicle controlled by Strike founder Jack Mallers, has filed a three-way merger proposal with Tether Holdings as confirmed major stakeholder. The structure positions Tether's $137 billion in circulating USDT as operational capital for payment infrastructure Mallers has spent four years building across Lightning Network rails.
The filing names Tether not as acquirer but as anchor participant in a triangular structure that leaves Twenty One Capital as surviving entity. Mallers retains operational control. The third party remains undisclosed in public filings but market participants familiar with the structure point to either a custody provider or a licensed money transmitter already integrated with Strike's rails. Tether's participation converts what began as a venture-stage Lightning wallet into a stablecoin-native settlement layer with immediate access to $5.2 billion in quarterly fee revenue Tether generates from Treasury holdings backing USDT.
This matters because Tether has historically operated as pure issuance infrastructure, earning yield on reserves while remaining agnostic to payment rails. Vertical integration into a consumer-facing network Mallers built suggests Tether sees margin compression ahead in commoditized stablecoin issuance. Circle's USDC already trades at functional parity with USDT in most markets. PayPal's PYUSD launched with zero-fee on-ramps. Tether's move into payment rails owned by Twenty One Capital secures distribution that doesn't rely on exchange partnerships or DeFi protocols, both vulnerable to regulatory reclassification. Mallers' Strike processed $6.8 billion in Bitcoin-to-fiat conversions in 2024, nearly all of it settling through Lightning channels that now connect directly to Tether's balance sheet.
The structure also solves Tether's ongoing banking access problem. Mallers spent three years building correspondent relationships with regional U.S. banks willing to handle crypto-adjacent flow if it never touches their core systems. Strike's architecture keeps Bitcoin and stablecoins off-balance-sheet, settling in dollars through traditional ACH and wire channels. Tether gains compliant dollar on-ramps without exposing partner banks to digital asset custody risk. Twenty One Capital gains operational leverage over $137 billion in float that currently sits idle in short-term Treasuries.
Allocators should watch for Federal Reserve commentary on bank partnerships with stablecoin-adjacent infrastructure, expected in Q2 guidance updates following March FOMC. Tether's public auditor, BDO Italia, will likely face questions on consolidation treatment if the merger closes, which would force disclosure of previously opaque reserve composition. Mallers has signaled intent to expand Strike into equity trading and money market fund access by year-end, both requiring additional licensing that becomes simpler with Tether's regulatory footprint behind the entity.
The filing landed the same week Coinbase announced $4.3 billion in Q4 stablecoin revenue, nearly matching trading commissions for the first time. Payment infrastructure that controls issuance now commands the valuation premium.
