According to , venture capital giants SoftBank Group and ARK Investment Management are among potential investors considering a combined investment of up to $20 billion in Tether.
As , if successful, the funding round could value the company at up to $500 billion, placing it among the world’s most valuable private enterprises.

Tether CEO Paolo Ardoino confirmed earlier this week that the company is exploring a potential fundraise “from a select group of high-profile key investors,” though he declined to disclose specific names or amounts.
Ardoino also hinted that Tether could expand into new business lines, including commodities, energy and media, as part of its broader growth strategy.
The investor interest reflects Tether’s dominant position in the stablecoin market, which has evolved from a tool for crypto traders into a strategic financial asset.

However, while yields remain historically elevated, the three-month Treasury yield now sits below its peak levels from 2023 and 2024, potentially signaling a need for T-Bill-rich firms to reduce their reliance on interest income.
In addition to interest income, Tether has also generated revenue from secured lending, issuing collateralized loans backed by its reserves — a line of business that has further contributed to its overall profitability.
