An American congressman who publicly advocates banning stock trading for legislators has found himself at the center of a scandal over his family's suspiciously well-timed trade. The lawmaker in question is Ro Khanna, a Democrat from California representing the House of Representatives.

According to disclosed transaction data, the politician's spouse sold Nvidia shares twice — on September 4 and October 7. Each transaction was worth between $1,000 and $15,000. The exact amount cannot be determined: American legislators are only required to disclose transactions as ranges rather than specific sums.

Nvidia shares hit an all-time high on October 6. From October 7 to November 11, they fell by nearly 27%, to $173.73. Thus, the October 7 sale came literally the day after the peak — on the eve of a sharp crash.

Selling at the peak before the crash

The crash began after a scandal surrounding Nvidia CEO Jensen Huang. In a letter to employees, he admitted to an extramarital affair. The woman in question is Alice Huang, a top executive at Megaspeed, a company that purchases Nvidia products. Intelligence agencies believe she is a Chinese spy.

Nvidia's board of directors launched an independent investigation and noted that it has so far seen no signs of secrets being leaked. China's Foreign Ministry called the espionage allegation unfounded. On November 12, it became known that Nvidia head Jensen Huang had resigned.

What's wrong with the trade

Ro Khanna sits on the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party. This committee investigates China's attempts to acquire American technology. At the same time, the congressman has publicly stated that members of Congress should not trade stocks.

There is no direct evidence that the politician's family knew about the scandal in advance. Therefore, the possibility of a mere coincidence cannot be ruled out.

Cryptalist analysis: The Ro Khanna case is another reminder of the structural conflict of interest in the American legislative process: even public support for a trading ban for congressmen does not eliminate the risks associated with transactions by their family members. For the market, such episodes increase pressure in favor of tightening rules on transaction disclosure and raise reputational risks around securities that are sensitive to political and regulatory news.
