CryptoWorld reports that Tether is encouraging investors to participate in a new funding round at an estimated valuation of approximately $500 billion. If market demand falls short of expectations, the fundraising process may be delayed. The report states that the company has been exploring financing plans since last year, but some investors remain cautious about this valuation. If the funding is achieved at this valuation, Tether's size will surpass most U.S. banks, second only to JPMorgan Chase. Previously, Tether discussed raising about $15 billion to $20 billion through private placements, but related plans still carry uncertainty.
