Representative Ro Khanna is sitting on a paper gain of more than 5,000% after purchasing shares of SanDisk Corporation (NASDAQ: SNDK) less than a year ago.
A disclosure filing shows Khanna purchased between $1,001 and $15,000 worth of SNDK shares on Aug. 4, 2025. The transaction was reported on Sept. 9, 2025.
Since then, SNDK stock has surged approximately 5,039%, vastly outperforming the broader market, with the S&P 500 gaining about 18.6% over the same period.
As of press time, SNDK was trading at $2,184, up roughly 4,700% over the past year.
The filing does not indicate any wrongdoing, but the Congress trade timing has attracted attention, given the stock’s extraordinary performance.

A gain of more than 5,000% would have turned a $1,001 investment into roughly $51,000 and a $15,000 investment into more than $770,000 on paper.
The gain has drawn attention as SanDisk emerged as one of the biggest beneficiaries of the AI boom.
SNDK stock fundamentals
Since spinning off from Western Digital in early 2025, the company has benefited from surging demand for NAND flash memory and data center storage used in AI infrastructure.
Investors have cheered strong earnings, expanding margins, rising memory prices, and supply agreements reportedly exceeding $11 billion.
Major cloud providers, including Microsoft, Alphabet, Amazon, and Meta Platforms, have significantly increased spending on AI infrastructure, creating a favorable environment for memory and storage suppliers.
Meanwhile, Khanna was not the only lawmaker to bet on SanDisk. Congressional disclosures show that Gilbert Cisneros reported purchases in January and March 2026, while Josh Gottheimer disclosed a purchase in May 2026.
Lisa McClain also reported both purchases and sales of the stock in late 2025.
Overall, public congressional trading trackers show at least 14 lawmakers have disclosed trades in SNDK, reflecting growing interest in one of the market’s best-performing AI stocks.
Although there is no evidence that the SNDK trade involved any improper activity, the investment highlights concerns over possible use of insider information to trade.
