No. 1 in U.S. stock trading volume$Micron Technology (MU.US)$It closed down 0.98%, with trading volume at $17.385 billion.
$Micron Technology (MU.US)$On October 20, it was announced that investments would be made in the processing of critical minerals and the manufacturing of high-purity materials, supporting Indium Corporation's expansion of its refining and manufacturing operations in central New York State. The two parties will also enter into a long-term supply agreement to ensure Micron's access to these high-purity minerals.
The aforementioned investment is part of Micron's plan, announced in July, to allocate up to $3 billion to strengthen the U.S. semiconductor supply chain ecosystem.
2nd place$NVIDIA (NVDA.US)$It closed down 0.29%, with trading volume at $16.52 billion.
NVIDIA is advancing its nearly $10 billion European investment plan into Germany. At the "Invest in Germany" summit held in Berlin, NVIDIA signed a letter of intent with the German government, announcing investments in four German startups and reaching an AI‑factory cooperation agreement with Siemens, further solidifying its strategic positioning in the European industrial AI sector.
German Chancellor Merkel, in her opening address at the summit, called on the business community to encourage German SMEs to open up their data to AI, emphasizing Germany's intention to become a global leader in the industrial application of AI. Meanwhile, NVIDIA CEO Jensen Huang stated on stage that AI can only augment human capabilities rather than replace specialized expertise, characterizing it as a "new tool" for businesses.
3rd place$SpaceX (SPCX.US)$It closed down 0.11%, with trading volume at $13.908 billion.
In a press release, SpaceX reported revenue of $2.8 billion and net profit of $4.4 billion. In the same period last year, the company posted a net loss of $1.05 billion. This quarter, Starlink's subscriber base grew to 13.6 million, up from 12.0 million in the previous quarter. Total revenue from the connectivity business surged 69%, rising from $3.1 billion in the prior-year period to $5.25 billion.
SpaceX's financial report shows that, driven by growth in its artificial intelligence and Starlink businesses, the company's third-quarter revenue more than doubled, surpassing market expectations. At the same time, capital expenditures nearly tripled due to investments in computing infrastructure, and its stock price rose as much as 3% in after-hours trading. However, SpaceX's proprietary AI software—including Grok, developed under xAI—remains overshadowed by competitors such as OpenAI, Anthropic, and Google. SpaceX reported third-quarter revenue of $14.58 billion, above analysts' estimates of $12.72 billion, and posted a net profit of $4.4 billion for the three months ended September 30, compared with analysts' forecast of $1.57 billion. AI‑related revenue surged more than ninefold to $7.6 billion, primarily from leasing computing capacity; yet among the company's $19.6 billion in capital expenditures, AI accounted for $16.4 billion, a level SpaceX expects to remain stable in the near term. In the third quarter, Starlink subscribers reached 13.6 million, exceeding analysts' projections of 12.19 million—but this growth has come at a cost: as the company expands internationally by introducing lower‑priced plans, average monthly revenue per user fell from $99 in 2023 to $69 in the third quarter.
Musk said that the merger between Tesla and SpaceX is far from a done deal; it requires shareholder approval, and there are many advantages to such a merger. Musk added that SpaceX and Tesla have already established a committee to discuss the merger.

According to Bloomberg's forecast, Amazon's capital expenditures will reach approximately $220 billion by 2026, and this investment in Germany further underscores the company's ongoing commitment to cloud computing and AI infrastructure.
