This week in Washington, Huang is also scheduled to meet with Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, and other bipartisan members of Congress. Meanwhile, the Trump administration is finalizing a new framework that would require developers of the most advanced AI models to grant the U.S. government early access prior to public release and is weighing its policy stance on open-source AI.
3rd place$SanDisk (SNDK.US)$Closed down 7.32%, with trading volume of USD 24.931 billion.
U.S. memory chip stocks broadly tumbled on Wednesday. As of Wednesday's market close, the stock had declined for four consecutive trading days, accumulating a total loss of 36.9% over the period.
Rank 6 $Advanced Micro Devices (AMD.US)$ Closed down 5.51%, with trading volume of USD 13.948 billion.
On Wednesday, it was reported that Advanced Micro Devices launched ROCm.ai to accelerate AI development on AMD platforms.
Additionally, according to sources, AMD confirmed that the 4GB memory version of the Radeon RX 9050 graphics card is specifically designed for partner systems, and there are currently no plans to sell this 4GB variant outside of OEM systems. Unlike other downgraded versions that merely halve the maximum memory capacity, the Radeon RX 9050’s 4GB version also features half the memory bus width of the 8GB version, which theoretically results in a significant performance penalty.

Intel announced the completion of the U.S. Department of Defense's RAMP-C program. This initiative leverages Intel’s 18A process technology to help commercial and defense customers establish chip design environments, conduct chip testing, and validate early product prototypes.
The completion of the RAMP-C program lays the groundwork for Intel’s subsequent participation in the Secure Enclave secure manufacturing initiative.
8th Place $Meta Platforms (META.US)$ Declined 1.31%, with trading volume of USD 11.816 billion, ending a 10-day losing streak.

The model will feature a parameter count of 1.5 trillion and deliver significant improvements in supervised fine-tuning (SFT) and reinforcement learning (RL). Musk added that Grok 4.7 will be released several weeks after Grok 4.6, with an estimated parameter count of 2.1 trillion. Compared to Grok 4.6, Grok 4.7 will offer further enhancements across the board but will operate slightly slower while achieving higher token efficiency.
Ranked 11th $Alphabet-A (GOOGL.US)$ Rose 0.90%, with trading volume of USD 9.101 billion.
According to media reports on Wednesday, Google DeepMind has disbanded the dedicated team behind AlphaFold. Most researchers have been reassigned to projects including Gemini, AI programming, genomics, enzyme design, and nuclear fusion, while others have joined Isomorphic Labs, Alphabet’s AI-driven drug discovery company. Just two years after this star team helped DeepMind CEO Demis Hassabis and project lead John Jumper win the Nobel Prize in Chemistry, it has now been dissolved.
AlphaFold once comprised an interdisciplinary team of machine learning researchers, structural biologists, and engineers. With the completion of AlphaFold 3, this team gradually lost its independent structure, and its members were redistributed across various internal Google DeepMind projects. Google has not released a full list of personnel adjustments nor characterized the changes as layoffs.
Ranked 12th$SK hynix (SKHY.US)$ Fell 2.60%, with trading volume of USD 8.357 billion.
$SK Hynix (000660.KR)$On July 29, the company released its first earnings report since going public, reporting a more than fivefold year-over-year increase in operating profit for the first half of the year, though results fell short of expectations, leading to a decline in share price. Second-quarter revenue totaled KRW 79.32 trillion, with net profit reaching KRW 93.92 trillion, up 133% sequentially. The company attributed its record profitability to sustained price increases for DRAM and NAND, as well as strong sales of HBM, AI server DRAM, and enterprise SSDs.
Despite market concerns about a potential slowdown in AI-related investments, the company believes demand will continue to expand, and a significant improvement in the near-term supply-demand imbalance is unlikely. Due to accelerated production ramp-up and expanded investments, capital expenditures in 2026 are expected to exceed KRW 40 trillion. The company is advancing mass production of M15X and construction of the Yongin cluster, emphasizing its commitment to investment discipline—balancing capacity expansion with financial prudence while capturing growth opportunities.
