Recently, Elon Musk directly pointed out on social media that storage will become a core constraint in the era of autonomous AI, clearly optimistic about the long-term growth potential of Micron Technology, SanDisk, and SK Hynix, the three storage giants. Goldman Sachs predicts that by 2030, the monthly token consumption for global autonomous AI will reach 120 trillion, which is 24 times that of early 2026, with storage demand showing almost infinite growth. SanDisk, ranked second, rose 8.88%, with a transaction volume of $30.927 billion. NVIDIA, ranked fourth, fell 0.07%, with a transaction volume of $20.543 billion. According to a financial document, NVIDIA has agreed to invest up to $105 billion to support a large new data center park in Ohio. This park will eventually be leased by OpenAI, marking a further deepening of cooperation between the two leading forces driving the AI boom. OpenAI announced on Monday that it has reached an agreement to obtain approximately 8 gigawatts of computing power from this park located in Pike County, with the first batch of 800 megawatts expected to be operational before 2028. One gigawatt of power is sufficient to supply electricity to up to 750,000 American households at any given time. SpaceX, ranked sixth, rose 4.45%, with a transaction volume of $16.989 billion. Latest data shows that family offices of ultra-high-net-worth individuals from the Americas, Europe, and the Middle East have accumulated holdings in SpaceX worth billions of dollars. According to data compiled from 13F regulatory filings, as of the end of June, Tao Capital, the family office of Hyatt Hotels heir Nick Pritzker, holds approximately $1.8 billion in SpaceX stock. BlueCrest Capital, owned by Michael Platt, and an investment firm under the Brazilian Moreira Salles financial family, have disclosed SpaceX holdings exceeding $100 million. Microsoft, ranked seventh, fell 3.04%, with a transaction volume of $13.659 billion. The corporate bond issuance under the code name "Odyssey Plan" is expected to be raised to $3.9 billion. This data center financing bond related to Microsoft offers yields close to junk bonds, with market subscription demand exceeding twice the issuance target. Insiders revealed that the bond is issued by a subsidiary of QTS Realty Trust, in which Blackstone Group has a stake, to fund a project in Georgia. Sources say that after several days of roadshows, market demand has surpassed $8 billion, creating conditions for increasing the bond size by approximately $1 billion. Meta Platforms, ranked eleventh, fell 3.54%, with a transaction volume of $9.674 billion. The federal court in Oakland, California, officially launched a significant trial against Meta this week. The attorneys general of California, Colorado, Kentucky, and New Jersey accuse Meta of intentionally designing features on Facebook and Instagram to addict teenagers while misleading the public about the safety of the platform And is suspected of violating the Children's Online Privacy Protection Act (COPPA). The plaintiffs are seeking up to $1.4 trillion in damages (close to the company's market value) and are demanding the platform to undergo product modifications. Mark Zuckerberg and Instagram head Adam Mosseri are expected to testify. Reddit's stock fell 7.63%, with a trading volume of $6.263 billion. Reddit will join the S&P 500 index this week through a non-routine adjustment. Reddit's previously announced financial report showed that revenue growth has exceeded 60% for the eighth consecutive quarter, with second-quarter revenue increasing by 61% year-on-year to $805 million, and net profit attributable to the parent company rising by 183% year-on-year to $253 million, showcasing strong overall financial performance.
