President Donald Trump’s eldest son, Donald Trump Jr., has invested in Thumzup Media Corp., a social media firm building a Bitcoin treasury. According to Bloomberg , Trump Jr. acquired 350,000 shares of the Los Angeles-based company, valued at over $4 million at the time of disclosure. Notably, the purchase was made following a recommendation from his investment adviser, and he has no active role within the company. The stake was revealed shortly after a $6 million private placement of convertible preferred stock, arranged by Dominari Securities, where both Donald Jr. and his brother Eric Trump serve as advisers to the parent company. Thumzup, which operates an app that pays users to promote products on platforms like Instagram, has posted minimal revenue alongside net losses. In the first quarter of 2025, the firm reported a $2.2 million loss on just $151 in revenue. Despite the financial performance, the firm has attracted attention due to its Bitcoin-forward treasury strategy.
