Where is the main support for the current risk market? In the past week, the policies and corporate dynamics in the field of AI in the United States have provided significant support for the US stock market, especially in the context of increasing macro uncertainty. AI has become one of the few sectors that can provide structural upward momentum. Large technology companies including Google, Meta, Microsoft, and Amazon have confirmed in their financial reports and investment plans that their AI infrastructure investment will exceed $350 billion by 2025, and may even approach $400 billion. This does not include the investment that the US government and overseas institutions are preparing to make in the field of AI in the United States. This scale means that even if economic data is under pressure, AI investment itself is enough to contribute nearly 0.7% to the growth rate of US GDP, which is equivalent to offsetting more than half of the potential slowdown pressure. On the policy side, the US Congress has once again proposed the Unleashing AI Innovation in Financial Services Act, which opens up an AI sandbox environment for the financial sector, accelerates technology application and compliance adaptation, and the White House promotes the export of AI assets and the development of open source standards to reduce institutional friction in industry development. In terms of capital flow, AI and its related cloud computing, chip, and software service sectors still attract a large amount of actively allocated funds, forming an independent support effect that deviates from the overall market sentiment. At present, the market generally believes that the valuation expansion brought about by the AI investment wave has even surpassed the direct impact of tariffs and trade policies on the US stock market. The spillover effects of capital expenditures brought about by infrastructure investment, coupled with the decrease in uncertainty driven by policies, and the synchronous repair of profits and valuations of leading enterprises, have made AI play a role as both a growth driver and a defensive pillar in the current US stock market structure. And because cryptocurrency itself is highly correlated with the US stock market, if the overall US stock market can maintain an upward trend due to the power of AI, then at least the trend of Bitcoin will not be too bad.
