AI Financial, a publicly traded crypto firm tied to President Donald Trump’s family, has purchased a startup owned by one of the company’s own advisors. According to filings with the Securities and Exchange Commission, the Las Vegas-based company struck a deal last Monday worth up to $43 million to buy the crypto infrastructure business Block Street.
Corporate records show Block Street was only incorporated in Nevada in late October. Matthew Morgan, the advisor to AI Financial, who is also the CEO and biggest shareholder of Block Street, said he founded the company about 16 months ago.
Formerly called Alt5 Sigma, AI Financial rebranded on Wednesday and is a public company whose business has swung between biotech, fintech, and now crypto. In August, the firm struck a deal with World Liberty Financial, a Trump family crypto company, to stockpile $1.5 billion in cryptocurrency on its balance sheet. In return, World Liberty Financial received stock in AI Financial and board seats.
The arrangement coincided with a 2025 fad that saw small publicly traded companies load up with cryptocurrency in order to spur a pop in their share prices.
AI Financial’s decision to acquire Block Street is notable given that the crypto deal in August saw Morgan named as chief investment officer before the appointment fell through amid a reshuffling of the C-suite. He later became an unpaid advisor, he told Fortune in an interview.
