Global AI Investment Surges Past $1 Trillion as Bubble Warnings Echo 2008 Crisis Fears

Global spending on artificial intelligence infrastructure is racing past $1 trillion in 2026, with foreign governments and sovereign wealth funds pouring unprecedented sums into US tech firms—a financial velocity that has drawn sharp comparisons to the conditions preceding the 2008 financial meltdown. Venture capital allocations to AI startups hit $300 billion in the first quarter alone, with 81% of all venture funding flowing to artificial intelligence companies. The concentration is striking: the United States captured 83% of global venture capital in early 2026, nearly double its 55% share a year earlier. A single cluster of four companies—OpenAI ($122 billion raised), Anthropic ($30 billion), xAI ($20 billion), and Waymo ($16 billion)—claimed roughly 63% of all global venture investment in the period.
