The news that OpenAI is close to reaching a major $10 billion cooperation with Amazon has injected optimism into the market [1]. OpenAI’s recent commitments in infrastructure have exceeded $1.4 trillion, including large-scale investments with chip manufacturers such as NVIDIA, AMD, and Broadcom [1]. This sustained large-scale investment expectation supports the valuation of the entire AI industry chain.

The talent competition between tech giants is heating up. OpenAI has poached more than 24 employees from Apple in 2025, far higher than about 10 in 2024 [1]. This fierce talent competition reflects the industry’s emphasis on future technology dominance, and investors interpret it as an important indicator of industry prosperity.

Recent regulatory environment has shown positive signals. The White House has approved the sale of H200 chips to some Chinese customers [1], which has alleviated market concerns about the escalation of Sino-US trade frictions and provided support for tech stocks.

Mid-December is the end of the quarter, and institutional investors usually rebalance their portfolios and allocate funds to tech stocks with growth potential.

3. Competition Risk
   : The competitive landscape in the AI field is still evolving rapidly, and leading positions may change.

: The current divergence of tech stocks reflects the market’s re-evaluation of the fundamentals and growth prospects of different companies. Investors should pay attention to the long-term opportunities brought by AI infrastructure investment, while remaining vigilant about valuation and risks, and maintain flexibility and discipline in pre-market and post-opening transactions.
