AI Bubble or Boom? Comparing Today’s Valuations to the Dot-Com Crash 25 Years Ago

As AI investments soar, market watchers are drawing stark parallels between the current artificial intelligence boom and the dot-com bubble of the late 1990s, which famously burst in March 2000. While OpenAI CEO Sam Altman and Meta’s Mark Zuckerberg acknowledge the massive infrastructure buildout and high valuations, experts debate whether history is set to repeat itself.

The dot-com crash wasn’t a single event but a confluence of factors: the Federal Reserve’s interest rate hikes in 1999-2000 and a global economic recession. This made speculative tech investments less appealing, exposing internet companies with astronomical valuations but little to no revenue. A key parallel for today’s AI boom is the ‘infrastructure overbuild’ seen in the late 90s, where telecom companies laid millions of miles of unused fiber optic cable, leading to catastrophic overcapacity and company failures like Corning and Ciena.

Today, companies like OpenAI, SoftBank, Oracle, and MGX are backing the $500 billion Stargate Project for a nationwide AI data center network, echoing the past’s aggressive expansion. However, crucial differences exist. Unlike many dot-com startups, major AI players are generating substantial revenue. Microsoft’s Azure cloud service, heavily focused on AI, saw 39% year-over-year growth to an $86 billion run rate, and OpenAI projects $20 billion in annualized revenue by year-end.

Despite this, a significant ‘reality check’ looms. Tech giants have invested approximately $560 billion in AI infrastructure over the last two years, yielding only $35 billion in AI-related revenue combined. An MIT study also found that 95% of AI pilot projects fail to produce meaningful results, despite over $40 billion in generative AI investment. The core question for investors remains whether current valuations and infrastructure spending are justified by near-term returns, or if, like the ‘dark fiber’ of the 90s, much of today’s AI infrastructure will sit idle awaiting demand to catch up with supply.
