Artificial intelligence infrastructure investment drove approximately 50% of inflation-adjusted GDP growth during the first six months of 2025. Microsoft, Amazon, Alphabet, and Meta are expected to spend $344 billion on capital expenditures in 2025, equivalent to 1.1% of GDP.

The White House is discussing whether to allow Nvidia to export H200 AI chips to China, Bloomberg reported. The H200 offers greater performance than the currently permitted H20 model but remains based on older Hopper architecture, while the advanced Blackwell series stays banned.

Constrained capacity investment, supply chain shifts, and Nvidia's pivot to LPDDR technology have triggered a memory supercycle. TrendForce projects Q4 pricing will rise 75% year-over-year. DDR4 and DDR5 module costs have surged 130–180% over 18 months, data show.

AI startup Anthropic will invest $50 billion to build data center infrastructure across the United States, partnering with Fluidstack to launch initial facilities in Texas and New York City in 2026.

Elon Musk's artificial intelligence startup xAI is seeking $15 billion in new equity funding at a $230 billion valuation, according to The Wall Street Journal.

Anthropic's valuation reached approximately $350 billion on November 19, 2025, following new investment commitments from Microsoft and Nvidia, according to Bloomberg. Microsoft pledged up to $5 billion while Nvidia committed up to $10 billion, substantially exceeding the AI startup's September valuation of $183 billion. The investments mark a strategic expansion for Microsoft beyond its existing OpenAI partnership and establish Nvidia's first deep technical collaboration with Anthropic.

Oracle shares dropped 5% in mid-November 2025 as Wall Street questioned the viability of its $300 billion, five-year partnership with OpenAI. The cloud provider is raising $38 billion in new debt to fund AI infrastructure expansion, which would push total obligations to $96 billion. Analysts expressed concern about whether OpenAI can sustain the $60 billion in annual payments Oracle expects, while credit default swaps on the company's debt reached a two-year high.
