Trump Jr. Backs Bitcoin Treasury Strategy with Major Stake in Thumzup

Donald Trump Jr. has made a significant investment in Thumzup Media Corp., a social media startup that is implementing an ambitious crypto treasury strategy. A recent regulatory filing shows that he owns 350,000 shares of the company, valued at over $4 million based on Tuesday’s closing price of $12.36 per share.

Thumzup Bets Big on Bitcoin and More

Thumzup, headquartered in Los Angeles, operates an application that compensates users for endorsing products on Instagram. While its user expansion remains uncertain, the company incurred a $2.2 million loss with a mere $151 in revenue during the first quarter of 2025. Nonetheless, the stock rose by 75% over four trading days before dropping by 17% on Wednesday.

Trump Jr. acquired the recommendation from his financial adviser. Although he does not hold an official position at Thumzup, the transaction highlights his increasing engagement in the cryptocurrency sector. This investment follows closely behind Dominari Securities, a company where both Donald Jr. and Eric Trump provide advisory support to the parent organization, completing a $6 million private placement of Thumzup’s convertible preferred stock.

In January, Thumzup indicated that it aimed to allocate most of its liquid assets into Bitcoin, marking a strategic transition towards a corporate approach reminiscent of MicroStrategy’s well-known cryptocurrency holdings. The company currently retains over $2 million in Bitcoin and announced intentions to expand into six other digital currencies, utilizing the newly raised capital.

The Trump family continues to strengthen its connections to the crypto industry. Earlier this year, Eric Trump joined the advisory board of Metaplanet, a Japanese company that is shifting its focus to Bitcoin investments. At the same time, the Trump Media & Technology Group, which operates Truth Social, committed $2.3 billion to Bitcoin initiatives.

Trump Support Crypto

President Donald Trump, a known critic of cryptocurrencies, now supports the sector, expressing his desire to establish the United States as the “crypto capital of the world.” His evolving strategy concerning digital assets, from World Liberty Financial to the introduction of the Trump memecoin, increasingly represents a significant part of his family’s investment landscape.

However, speculations continue to grow as Thumzup and the Trump Organization have yet to provide official statements regarding their recent activities.
