Cryptocurrency has become the Trump family's biggest business. President Trump's latest financial disclosure, filed with the US Office of Government Ethics, shows the family earned roughly $1.4 billion from crypto ventures in 2025, by far its largest single source of income, dwarfing hotels and golf courses, according to NBC News. Two projects did most of the work, and behind them stands one recurring name: the crypto entrepreneur Justin Sun.
Where the money came from
The bulk of the haul came from two sources. The larger was the $TRUMP memecoin, a token bearing the president's name that generated more than $600 million in fees and royalties for Trump-linked entities, per NBC News. A "memecoin" is a cryptocurrency with no real product behind it; its value rests almost entirely on hype and sentiment. The second was World Liberty Financial (WLF), a crypto venture co-founded by Trump and his sons, whose token sales brought in hundreds of millions more. The rest came from smaller holdings and a stablecoin, a token pegged to the dollar.
A striking feature of the memecoin is who profits and how. Trump-linked entities hold most of the token supply and, crucially, collect fees on trading whether the price rises or falls, according to CNN. That matters because the coin has been a losing bet for most buyers: blockchain analysis cited by CNN and others found that a large majority of wallets that bought $TRUMP are underwater, with collective losses running into the billions, even as the president's entities booked their share of the fees.
Enter Justin Sun
Justin Sun, founder of the TRON blockchain, was among the most important backers of the Trump crypto machine. He invested tens of millions of dollars into World Liberty Financial and was given an advisory role and a large allocation of its tokens, according to CoinDesk. His money and endorsement helped give the venture credibility and capital at a formative moment.
The timing drew attention for another reason. Sun had been sued by the US Securities and Exchange Commission in 2023 over allegations tied to his crypto businesses; that case was wound down in 2026 through a settlement, reported at around $10 million, in which Sun did not admit wrongdoing. Critics have questioned the optics of a figure under federal investigation becoming a major investor in the president's crypto venture; no finding of improper coordination has been made, and Boursel presents the concern as one raised by observers, not a proven fact.
The falling out
The partnership has since turned adversarial. In 2026 Sun sued World Liberty Financial, alleging it had frozen a large tranche of his tokens and shut him out; the company countersued, accusing him of improper trading and misconduct. Both sets of claims are allegations being fought in court, and neither has been proven.
Why it matters
Set aside the personalities and the significance is structural: a sitting US president's family is earning enormous sums from crypto ventures whose value depends on the very industry his administration regulates. That arrangement, tokens the public can buy that enrich the president while he shapes crypto policy, is what ethics experts have flagged as an unprecedented conflict of interest. Supporters counter that the businesses are disclosed and legal. For a global financial audience, the numbers alone tell the story of how quickly, and how lucratively, the Trump family has moved into crypto, and how tangled the ventures behind that $1.4 billion have become. Boursel takes no political view and offers no investment advice.
