Internet reports that SoftBank and ARK are negotiating to participate in Tether's main financing round. Tether, the world's largest issuer of stablecoin, is seeking to raise up to $20 billion at a $500 billion valuation in a deal that could elevate Tether to one of the world's most valuable private companies, putting it on par with OpenAI and SpaceX. Tether hopes to raise US$15 billion to US$20 billion, or about 3% of the company, through a private placement, and negotiations are still in their early stages.
