Jane Street Reloads on Shopify: Position Surges 540%, Emerging as Its Second-Largest Single Stock Holding

BlockBeats News, August 25th, according to regulatory filings, quantitative trading giant Jane Street significantly increased its holdings in AI storage chip manufacturer SanDisk (SNDK), with the number of shares increasing to 7.41 million, holding a position value of approximately $9 billion, an increase of 6.25 million shares from before, representing a growth of about 540%. SanDisk has also risen to become Jane Street's second largest single stock holding, second only to SPY.

The filings show that Jane Street currently holds approximately 5.47% of SanDisk's outstanding shares, with a position size even exceeding Amazon, Nvidia, and Microsoft. SanDisk has surged over 3000% in the past 12 months, but has retraced about 36% from its historic high, experiencing significant stock price volatility.

SanDisk's recent performance has been driven by AI data center demand. The company's 2026 fiscal year data center revenue grew by 437% year-on-year to $5.15 billion, with data center shipments accounting for 38% compared to 12% a year ago. The company has now signed long-term supply agreements with 8 customers, including 3 U.S. hyperscale cloud providers, with expected total contract revenue of at least $93.9 billion, and remaining performance obligations of $91.1 billion.

SanDisk expects that AI inference demand will continue to drive NAND flash market growth and is developing High Bandwidth Flash (HBF) products for AI inference workloads, with plans to provide samples to customers next year.

Although Jane Street has not publicly disclosed a target price, its action of increasing holdings by over 500% in a single quarter has become a significant signal in the market's attention to the AI storage sector.
