SoftBank Group (OTCPK:SFTBY [https://seekingalpha.com/symbol/SFTBY]) (OTCPK:SFTBF [https://seekingalpha.com/symbol/SFTBF]) and Cathie Wood's Ark Investment Management are potential investors in a funding round that seeks to raise $15B-$20B for a 3% stake in stablecoin giant Tether, according to a media report on Friday.

The company behind the world's largest stablecoin Tether (USDT-USD [https://seekingalpha.com/symbol/USDT-USD]) could be valued at as much as $500B as a result, making it one of the largest private companies globally.

Attracting high-profile investors like SoftBank (OTCPK:SFTBY [https://seekingalpha.com/symbol/SFTBY]) and Ark would go a long way in bolstering Tether's credibility among mainstream investors, Bloomberg News reported [https://www.bloomberg.com/news/articles/2025-09-26/softbank-ark-in-talks-to-invest-in-tether-s-major-funding-round?srnd=homepage-americas], citing people familiar with the matter. The company has been seeking to attain political legitimacy after it had previously been under scrutiny in the U.S. for Tether's (USDT-USD [https://seekingalpha.com/symbol/USDT-USD]) alleged role in illicit financing.
