Just as Wall Street is becoming more and more skeptical about the return on investment of AI technology and global investor confidence is gradually shaking, Nvidia has delivered an answer that has made the market boil. Last night, the world's largest chip company by market capitalization announced its fourth quarter financial report for fiscal year 2026 and performance forecast for the first fiscal quarter of fiscal year 2027. Both data significantly exceeded market expectations.The results were immediate: U.S. technology stocks rebounded, Bitcoin soared 7.76% in a single day, and AI concept tokens collectively soared by more than 20%. On one side is the caution of capital, on the other side is the crazy investment of giants Since the beginning of this year, the global capital market's attitude towards AI has been undergoing subtle changes - expectations for investment return are getting lower and lower, and confidence is gradually weakening. But at the same time, American technology giants are still ramping up their investments.Annual AI spending budgets released by Amazon, Meta, Microsoft, Google and other companies show that their total investment in this field will exceed US$650 billion by 2026.Amazon alone is expected to spend as much as $200 billion on AI throughout the year. The scale has investors both excited and terrified.What is exciting is that there is no doubt about the deterministic demand for AI; what is scary is how much real money profit can such a huge investment be converted into in the future? NVIDIA's financial report just gave the market an answer. Exploding financial report: Demand is still in a "greedy state" Data show that in the fourth fiscal quarter as of January 31, 2026, Nvidia's revenue reached US$68.13 billion, a year-on-year increase of 73%, exceeding market expectations of US$66.21 billion; net income doubled from US$22.1 billion in the same period last year to US$43 billion. More importantly, the revenue of the data center business (i.e., AI chip business), which accounts for more than 91% of sales, reached US$62.3 billion, which also exceeded analyst expectations. The outlook for the future is even more reassuring for the market: NVIDIA expects revenue in the first quarter of fiscal 2027 to be between US$76.44 billion and US$79.56 billion, much higher than Wall Street's estimate of US$72.78 billion.The company also emphasized that this forecast does not include data center revenue in the Chinese market. what does that mean?Even excluding the Chinese market, global demand for AI computing power continues to expand. Why can NVIDIA's financial report influence the entire market? Nvidia is no longer just "a chip company", but one of the most important economic indicators in the global financial market - in the eyes of some investors, it is even more valuable than the U.S. non-farm payrolls report or the Federal Reserve's interest rate decision. There are three reasons: First, it is an “indicator light” for AI infrastructure investment.The market has been worried about the "AI bubble" before, but NVIDIA's financial report proves that the global demand for computing power is still growing greedily, and the worry about the "bubble bursting" has been greatly weakened. Second, it is large enough.NVIDIA's current market value is as high as US$4.75 trillion, accounting for 8% of the weight in the S&P 500 Index.Its rise and fall directly affects the direction of the Nasdaq 100 and S&P 500.If it explodes, the entire U.S. technology sector will be hit hard. Third, in the current macro environment of tense relations between the United States and Iran and uncertainty about Trump's tariff policy, Nvidia's performance has become a "reassurance" for the risk market. Carnival of Bitcoin and AI coins The cryptocurrency market itself is a market with a high risk appetite and is extremely dependent on liquidity and optimism.NVIDIA's financial report exceeded expectations, directly ruling out the huge negative factor of "AI bubble bursting". The results are obvious: Bitcoin was at the critical point of the long-short game of US$65,000 two days before the financial report was released, and it rose 7.76% in a single day after the financial report was released, once approaching US$70,000.AI concept tokens are having a collective carnival, with FET, RNDR, NEAR, etc. generally increasing by more than 20%. It can be said that if NVIDIA's financial report falls short of expectations, the collapse of U.S. technology stocks may trigger a liquidity crisis, and Bitcoin is likely to fall back to $60,000; and the better-than-expected performance of the financial report provides a much-needed optimism catalyst for Bitcoin to break through $70,000. Conclusion NVIDIA's "full score answer sheet" has temporarily stabilized the global risk market.But another question it raises remains unresolved: How much return will the $650 billion investment ultimately yield? At least for this moment, the market is choosing to believe the answer is positive.
