AI Once Again Drives US Stock Market Gains
This week, US equities continued their strong performance, with the S&P 500 and Nasdaq indices hovering near historic highs. The primary driver of this rally remains the artificial intelligence sector. The Philadelphia Semiconductor Index surged nearly 6% in a single day, signaling renewed capital inflows into the chip supply chain. The turning point in market sentiment came from Nvidia.
At the Taipei Computex conference, Nvidia CEO Jensen Huang unveiled a new chip platform designed for AI PCs and announced partnerships with Microsoft, Dell, HP, and other companies to build out the AI PC ecosystem. Following the announcement, stocks linked to Nvidia, Micron, and Dell attracted significant investor interest.
Unlike last year, when the market focused solely on GPUs, this year capital is spreading across a broader AI value chain, including:
- AI chips
- AI servers
- Data centers
- AI PCs
- Enterprise software
- AI agents
The market is shifting from "buying Nvidia" to "buying the AI ecosystem."
Alphabet’s $80 Billion Funding Plan Draws Market Attention
Another major event sparking discussion comes from Alphabet. Alphabet announced an $80 billion funding initiative to build AI infrastructure and related data center projects. Part of the funds will support the development of AI products such as Gemini. Although Alphabet’s stock price fluctuated briefly after the news, the market is paying close attention to a deeper signal:

Global tech giants continue to ramp up AI investment. From Microsoft and Amazon to Meta and Alphabet, nearly every major technology company is accelerating the expansion of AI data centers. This indicates that the surge in AI investment over the past two years has not slowed; instead, it is intensifying.
For semiconductor, server, and infrastructure suppliers, this increase in capital expenditures remains the most important source of growth.
Broadcom Emerges as a New Focal Point
Beyond Nvidia, Broadcom has recently become another AI stock frequently mentioned on Wall Street. Broadcom’s shares have risen nearly 30% year-to-date, with market attention centered on its custom AI chip business. As tech giants like Google and Meta develop specialized AI chips, Broadcom stands out as a key beneficiary.
Compared to Nvidia, Broadcom’s advantages include:
- Growing demand for custom AI chips
- Rising demand for network switching equipment
- Ongoing expansion of data center construction
With earnings reports approaching, the market is closely watching Broadcom’s outlook for future AI orders.
If investment in AI infrastructure continues to grow, Broadcom is likely to become one of the most prominent AI stocks after Nvidia.
Risks Remain
While the overall market sentiment is optimistic, risks persist.
Interest rate concerns: Recent US job vacancy data came in above expectations, and some Federal Reserve officials have indicated that if inflation continues to rise, further tightening of monetary policy is possible.
Geopolitical risks: Ongoing tensions in the Middle East continue to impact the energy market, keeping oil prices elevated. If energy prices keep rising, inflation could be pushed higher, affecting expectations for future rate cuts.
More institutions are discussing whether AI valuations are overheating: The current market narrative centers on AI-driven earnings growth over the next several years. If corporate profits fail to keep pace with expanding capital expenditures, some highly valued companies may face correction pressures.
How Can Digital Asset Investors Participate in the AI Rally?
For many crypto asset investors, AI has become a major theme impacting both the digital asset and stock markets. On one hand, the AI narrative is driving the development of certain crypto projects. On the other, the largest capital inflows are still going to US tech giants like Nvidia, Broadcom, and Microsoft.
As a result, more investors are looking to diversify beyond digital assets by allocating to equities and participating in the long-term AI growth trend across different markets. In this context, multi-asset allocation is emerging as a new investment strategy. Through Gate stock trading, users can use USDT to trade over 10,000 stocks and ETF products, managing both digital assets and equities within a unified account system. This provides a more convenient way to access global capital markets.
Conclusion
As we move into mid-2026, AI remains the central theme for US equities. From Nvidia ushering in the AI PC era, to Alphabet’s massive capital spending plans, and the ongoing benefits for infrastructure companies like Broadcom, market capital continues to seek new growth opportunities within the AI value chain.
However, while focusing on upside potential, investors should also remain alert to risks posed by interest rates, inflation, and valuation levels.
For those looking to capture global tech trends, it’s not just about AI itself, but also about how AI continues to reshape corporate profitability, industry structure, and the investment logic of global capital markets.
