AI Financial, a cryptocurrency company associated with the family of U.S. President Donald Trump, has acquired Block Street for $43 million. The acquisition, completed last week, marks AI Financial's strategic entry into the cryptocurrency infrastructure sector. Block Street, founded 16 months ago by Matthew Morgan, was incorporated in Nevada in late October 2026. Morgan, who serves as an advisor at AI Financial, is also the CEO and largest shareholder of Block Street. AI Financial, previously active in biotechnology and fintech, has shifted focus to cryptocurrency. In August 2025, it partnered with Trump's World Liberty Financial, agreeing to hold $1.5 billion in cryptocurrency, with World Liberty Financial receiving shares and a board seat in return. This acquisition is part of AI Financial's broader strategy to expand its presence in the crypto market.
