Tether Holdings SA, the issuer of the world’s most widely used stablecoin, is reportedly in talks to raise US$15–20 billion in new capital for roughly a 3% equity stake, a move that would value the company near US$500 billion—placing it alongside the world’s most valuable private firms.
For the broader digital-asset market this signals far more than a funding round. It suggests that stablecoins, long regarded as back-office infrastructure, are stepping into the centre of global finance.
Nigel Green, founder and CEO of global financial advisory giant deVere Group, comments: “If Tether secures capital of this magnitude, it’ll likely recast stablecoins as investable assets in their own right.
“Institutional investors have treated them as functional tools. A valuation approaching half a trillion dollars can be expected to force a reassessment of that view.”
He continues: “Such a raise would give Tether the resources to reinforce reserves, expand disclosure, and accelerate institutional adoption at a time when demand for a dependable, dollar-pegged digital instrument is intensifying.
“The credibility conferred by heavyweight investors will change the conversation.”
It validates the business model and sets a benchmark every other stablecoin issuer must meet or exceed.
Global market conditions add urgency. With volatility persisting across both traditional and crypto markets, a stable, blockchain-based dollar alternative backed by deep capital and transparent governance offers a compelling proposition for funds, corporates, and sovereign wealth vehicles alike.
Nigel Green highlights the competitive ripple effect.
“Capital of this scale raises the bar for the entire sector,” he notes. “Investors will demand greater transparency, stronger reserve management, and rigorous regulation from every player. We expect that this discipline will accelerate mainstream adoption.”
Tether’s token, USDT, already underpins daily trading volumes in the tens of billions and is embedded across exchanges, DeFi protocols, cross-border payments and settlement layers.
Yet the company has never before invited outside investment on such terms. A successful placement would shift it from dominant utility to cornerstone of digital finance.
“This could be a decisive step toward stablecoins becoming core infrastructure for the global financial system,” says the deVere CEO.
“We are witnessing the point where a stablecoin issuer could sit alongside the biggest private technology companies in valuation and influence.”
Regulators will watch closely. Oversight of reserve composition, governance standards, and systemic risk will be paramount. Nigel Green believes that scrutiny is ultimately positive. Greater regulatory engagement will create trust and robust frameworks are exactly what large-scale investors want to see.
He also expects a wider impact on capital flows. “Institutional portfolios that once ignored stablecoins will start treating them as strategic holdings.
“Liquidity management, yield strategies, and on-chain settlement all benefit when a dollar-linked token achieves this level of acceptance.”
He concludes: “This is about more than one company; it’s about the maturation of a sector.
“Should Tether close a deal on these terms, stablecoins will move from supporting act to headline asset class, with many global investors not wanting to be ‘late to the party’.”
