Tech Stocks rally as Nvidia market cap crosses Japan GDP level

Market milestone impact: Nvidia’s market capitalization surged beyond the estimated Japan GDP of around 4.2 trillion dollars, while Nvidia’s valuation crossed nearly 5.5 trillion dollars based on the latest market data, marking one of the biggest valuation gaps between a company and a major economy.
AI demand surge effect: Tech stocks gained as Meta Platforms, Amazon Web Services, and Microsoft Azure expanded AI infrastructure spending, with combined AI capex projected above 250 billion dollars over the next 12 to 18 months.
Investor inflow momentum: Institutional inflows into Tech Stocks increased by nearly 28 percent week on week, showing strong confidence in AI-driven earnings growth.
Semiconductor strength: Nvidia GPUs saw demand growth estimated above 80 percent year on year, driven by data center expansion and large language model training needs.
