The Trump-linked cryptocurrency venture World Liberty Financial filed a defamation lawsuit Monday against Chinese-born billionaire Justin Sun, escalating a legal clash that began just two weeks earlier when Sun sued the company and accused it of seizing his assets. The counterstrike, backed by a high-profile anti-defamation attorney, accuses Sun of waging a "public smear campaign" against the crypto start-up founded by Donald Trump Jr., Eric Trump, Barron Trump, and the sons of presidential envoy Steve Witkoff.
The lawsuit marks a sharp turn in what had been, until recently, a very lucrative relationship. Sun poured tens of millions into Trump-backed crypto projects after the 2024 election, publicly called himself the President's "top fan," and showed up to a meme-coin dinner at the President's golf course alongside 220 of the largest holders of the $TRUMP token. Now the two sides are trading accusations of fraud, retaliation, and market manipulation in open court.
Sun, the founder of the Tron blockchain and CEO of BitTorrent, has long cultivated a reputation for headline-grabbing spending. He paid $6.2 million for a banana artwork, bid $28 million for a seat aboard Jeff Bezos's Blue Origin space flight, and dropped $4.57 million in 2019 to win a charity lunch with Warren Buffett. He once publicly offered $30 million for an hour with Elon Musk. Musk did not respond.
After Trump won the 2024 election, Sun turned that same appetite toward the new president's orbit. He purchased $100 million worth of the $TRUMP meme coin last May and bought $75 million in digital coins from World Liberty Financial. Forbes estimated the Trump family netted $400 million in profits from that transaction alone.
Last September, Sun posted on X with unmistakable enthusiasm for the venture. The Daily Mail reported that Sun wrote at the time:
"I truly believe this will be one of the biggest and most important projects in crypto. The long-term vision here is too powerful, and I'm fully aligned with the mission."
That alignment did not last. World Liberty Financial says it froze Sun's assets in the company after discovering what the lawsuit describes only as "misconduct." The filing cites "suspected short selling" of Sun's own company's tokens and "straw purchases of $WLFI tokens on behalf of undisclosed third parties" as the basis for the freeze.
The youngest Trump brother, Barron, has been building his own public profile in recent months, and his connection to the crypto venture puts him squarely in the middle of a dispute that now involves hundreds of millions of dollars and two competing lawsuits.
Sun struck first. Two weeks before Monday's filing, he sued World Liberty Financial, accusing the company of "engaging in an illegal scheme to seize property." The details of his complaint, including the court where it was filed and the specific legal claims, remain unclear from available reporting.
World Liberty Financial's counterpunch frames the dispute differently. The defamation lawsuit claims Sun did not attempt to resolve the matter privately. Instead, the filing alleges, Sun's legal counsel threatened litigation that would "light World Liberty on fire" and make the company's token price "go to s***." When that didn't produce the result Sun wanted, the lawsuit claims, he "embarked on a scorched-earth pressure campaign" and retaliated publicly with "false claims."
The company retained Tom Clare, a top anti-defamation attorney whose prior clients include Johnny Depp and Brigitte Macron. Clare described the lawsuit as a "last resort to correct the record" and left little ambiguity about the company's posture.
"Rather than acting in good faith, Justin Sun chose to defame World Liberty, repeatedly, publicly, and to millions of followers. We are eager to expose the falsity of Sun's statements in court and in public."
Sun fired back on social media the same day. He called the defamation suit "nothing more than a meritless PR stunt" and said he looks forward to defeating the case in court.
"The alleged defamation lawsuit that World Liberty announced on X today is nothing more than a meritless PR stunt. I stand by my actions and look forward to defeating the case in court."
Sun did not respond to the Daily Mail's request for comment.
This is not Sun's first brush with American legal proceedings. In 2023, the SEC accused him in a civil case of manipulating the secondary market for his own crypto assets through wash trading, a practice in which a trader simultaneously buys and sells the same asset to create the illusion of market activity.
That case ended in March 2026 when the SEC dropped it in exchange for a $10 million penalty paid by one of Sun's companies. Sun did not admit wrongdoing as part of the settlement. The resolution removed a federal cloud, but it did not erase the underlying allegations from the public record.
The Trump family's expanding public footprint makes the lawsuit politically sensitive. World Liberty Financial was co-founded by Don Jr., Eric, and Barron Trump alongside Alex and Zach Witkoff, the latter identified as the venture's co-founder and CEO. Their father, Steve Witkoff, serves as the President's envoy, a connection that has already drawn scrutiny from congressional Democrats.
If House Democrats win a majority in November, they are expected to launch investigations into the Trump family's crypto interests. A messy, public legal battle with a Chinese-born billionaire who once positioned himself as the President's biggest booster would give investigators no shortage of material to work with.
For all the sharp language in Monday's filing, significant questions remain unanswered. The court where World Liberty Financial filed the defamation suit has not been identified. Neither lawsuit's case number or docket number has been disclosed in reporting so far. The specific social media posts alleged to be defamatory are not detailed. The nature and timing of the asset freeze that triggered the dispute remain vague, described only as a response to unspecified "misconduct."
The Trump family has projected unity in recent public appearances, but a protracted courtroom fight over a venture bearing the family name could test that image. The stakes extend beyond reputation. Forbes estimated the family earned $400 million from Sun's investments alone, a figure that will inevitably resurface as both lawsuits proceed.
Sun's pivot from cheerleader to litigant happened fast. Less than a year separates his glowing endorsement of World Liberty Financial and his accusation that the company illegally seized his property. The company's pivot was equally swift, from accepting $75 million in Sun's money to freezing his assets and hiring one of the country's most aggressive defamation lawyers.
The intersection of Trump family business and public conflict is nothing new, but the crypto space adds a layer of opacity that traditional real estate never carried. Token prices, wash-trading allegations, straw purchases, and frozen digital assets all operate in a regulatory gray zone that neither Congress nor the courts have fully mapped.
The defamation suit tells one story. Sun's lawsuit tells another. Both sides have obvious financial incentives to frame the facts in their favor, and neither has yet produced the kind of documentary evidence, transaction records, communications, internal memos, that would let the public judge which account holds up.
What is clear: a Chinese-born crypto billionaire with a prior SEC enforcement action poured more than $175 million into Trump-linked digital ventures, gained a seat at a dinner with the President, and is now locked in a legal brawl with the President's sons over what happened to his money. The courts will sort out the legal merits. The political fallout is already in motion.
When someone spends $175 million to get close to power and then claims his assets were seized, the public deserves answers, not dueling press releases. Both sides say they want their day in court. Good. That's exactly where this belongs.
