According to regulatory filings, quantitative trading giant Jane Street has significantly increased its holdings in AI storage chip manufacturer SanDisk (SNDK), raising its stake to 7.41 million shares with a position value of approximately $9 billion. This represents an increase of 6.25 million shares from its prior holding, a rise of around 540%, making SanDisk Jane Street’s second-largest single-stock position, second only to SPY. The filings show Jane Street currently holds roughly 5.47% of SanDisk’s outstanding shares, a position size even larger than its holdings in Amazon, NVIDIA, and Microsoft. SanDisk’s stock has surged over 3,000% in the past 12 months, though it remains about 36% below its all-time high with notable price volatility. SanDisk’s recent performance has been driven by demand from AI data centers. For its 2026 fiscal year, the company’s data center business revenue jumped 437% year-over-year to $5.15 billion, while data center shipments as a share of total output rose from 12% a year earlier to 38%. The company has now signed long-term supply agreements with 8 clients, including 3 U.S. hyperscale cloud service providers, with total contracted revenue projected at no less than $93.9 billion and remaining performance obligations standing at $91.1 billion. SanDisk expects AI inference demand to continue driving growth in the NAND flash market, and is developing high-bandwidth flash (HBF) products tailored for AI inference workloads, with plans to deliver samples to clients next year. While Jane Street has not publicly disclosed a target price, its move to boost its stake by over 500% in a single quarter has become a key signal for the market to focus on the AI storage sector.

The source noted that Pakistan is seeking to relay these conditions to the United States.

According to BIT (Bit.com) market data, U.S. stocks edged higher during Tuesday’s intraday session, with U.S. Treasury yields declining for the second consecutive day and chip stocks lifting the Nasdaq index. The S&P 500 rose 0.2%, the Nasdaq Composite gained 0.5%, and the Dow Jones Industrial Average was roughly flat. U.S. Treasury yields continued to pull back, with the 10-year Treasury yield falling to 4.658%. Earlier market reports noted that the U.S. Treasury may deploy around $1 trillion in Treasury General Account funds for bond repurchases, driving long-dated U.S. Treasury yields lower. Chip stocks were the session’s highlights: Nvidia rose over 1%, AMD and Micron both gained around 3%, and Intel climbed more than 2%. Markets are awaiting Nvidia’s post-market earnings report on Wednesday, with the AI and semiconductor sectors drawing significant attention. Consumer stocks faced pressure meanwhile: Dick’s Sporting Goods plummeted over 27% due to disappointing earnings, a move that makes it highly likely to post its largest single-day percentage drop in history; Walmart fell around 1%, and Target dropped roughly 3%. Additionally, investors are waiting for the U.S. July Personal Consumption Expenditures (PCE) Price Index, scheduled for release on Wednesday. Recent oil price declines have eased some inflation concerns, with international crude oil prices falling more than 3% on Tuesday. Another key market variable this week is Federal Reserve Chair Kevin Warsh’s speech at the Jackson Hole Symposium on Friday, as markets will closely watch his latest remarks on monetary policy and interest rate outlooks.

Insight Beating AI News Flash: IBM unveiled a new dual-architecture mainframe processor at the Hot Chips conference, marking the first time a single chip natively runs both IBM mainframe instruction sets and Arm instruction sets, with nanosecond-scale switching speed between the two architectures—no emulation or conversion required. Built on 2nm process technology, the chip features 11 cores, a base frequency exceeding 5.7GHz, and an integrated AI inference accelerator capable of directly executing AI tasks like fraud detection during financial transaction processing. This development means institutions such as banks can integrate modern AI software ecosystems into their mainframe systems without rewriting decades-old mainframe code or deploying separate dedicated AI servers. IBM noted that this processor is the first major achievement of its partnership with Arm launched in April 2026. By supporting the Arm architecture, IBM mainframes will gain direct access to the vast Arm software ecosystem and AI development frameworks. A large number of global large financial institutions still rely heavily on mainframe systems; IBM’s core strategy in this move is not to replace traditional mainframes, but to extend their lifecycle by integrating Arm and AI capabilities. However, the chip’s specific launch timeline has not been disclosed, and its commercial rollout awaits further developments.

World Liberty Financial (WLF), a crypto project linked to the Trump family, saw its CEO Zach Witkoff state Tuesday that the USD1 stablecoin now has a circulating supply exceeding $4 billion, with its 24-hour trading volume peaking at $1.7 billion. He noted the stablecoin’s actual usage demand refutes external allegations that it is used to funnel benefits to Trump and his family. Witkoff added that he "never has and never will" discuss company business with Trump, emphasizing his primary focus is delivering products and services to users. Founded in 2024 by Trump, his son, and related parties, WLF currently operates the USD1 stablecoin and has received conditional approval for a U.S. national trust bank license. Meanwhile, WLF remains mired in conflict-of-interest controversies: a UAE-linked entity reportedly acquired a 49% stake in WLF, and the Trump family is set to earn hundreds of millions of dollars from WLF tokens and related equity transactions in 2025. Witkoff stressed that stablecoins are emerging as the internet’s "native cash layer," with USD1 set to continue expanding its applications moving forward.

Robinhood Chain ecosystem decentralized exchange Arcus has launched the pToken protocol, which tokenizes custodial perpetual contract accounts into transferable ERC-20 tokens, allowing users to gain leveraged asset exposure without directly managing margin and positions, while pTokens can be used in on-chain protocols such as lending. According to Arcus, each pToken represents proportional ownership of a perpetual contract account under a specific market and fixed leverage multiple, and users can trade pTokens just like spot tokens. The platform has rolled out leveraged products for assets including BTC, SOL, and HYPE, such as pBTC and pBTC3x, and also supports stock token leveraged products like pHOOD3x. Additionally, Arcus has introduced multi-asset collateral functionality, enabling eligible stock tokens including SPY, QQQ, and MAG7 to be used as collateral for perpetual contracts, with an initial loan-to-value (LTV) ratio of 50% — letting users access leverage without selling their underlying assets. Robinhood Chain officially launched its mainnet on July 1, with current total value locked (TVL) exceeding $600 million and cumulative DEX trading volume surpassing $26 billion. Arcus reports its cumulative trading volume has topped $250 million, with average daily trading volume over $3.3 million, TVL of $18 million, and more than 85,000 waitlist users for its perpetual contracts.
