Trump family-affiliated company AI Financial acquires Block Street for $43 million

Foresight News reported, according to Fortune magazine, that the publicly listed cryptocurrency company AI Financial (formerly Alt5 Sigma), which is linked to the family of US President Donald Trump, reached a $43 million deal last week to acquire cryptocurrency infrastructure company Block Street.

Company records show that Block Street was only registered in Nevada in late October. Matthew Morgan, an advisor to AI Financial and also the CEO and largest shareholder of Block Street, stated that he founded the company about 16 months ago. Morgan emphasized that the acquisition of Block Street was not a proprietary deal. In late 2025, he had pitched his yet-unprofitable company Block Street to multiple publicly listed firms and turned down deals promising potential returns of over $100 million.

AI Financial previously focused on biotechnology and fintech, and now has entered the cryptocurrency sector. In August last year, the company signed an agreement with the Trump family’s cryptocurrency firm World Liberty Financial to hold $1.5 billion worth of cryptocurrency on its balance sheet. In return, World Liberty Financial received shares and a board seat at AI Financial.
