Billionaire investor Mark Cuban has issued a stark warning about the current artificial intelligence arms race among tech giants like OpenAI, Google, Microsoft, Meta, Perplexity, and Anthropic. Speaking on the “Pioneers of AI” podcast in late 2025, Cuban compared today’s AI foundational model competition to the late 1990s search engine boom, which ended with Google dominating while rivals like Bing and DuckDuckGo were reduced to niche players. Cuban fears the AI industry may follow a similar winner-take-all scenario, concentrating power and market share in just one or a few dominant players.
Cuban criticized the current race to build the most powerful AI models, highlighting extensive overspending on infrastructure and data centers. He warned that this high-stakes competition risks creating a bubble fueled by excessive capital deployment on today’s technology, which may quickly become obsolete as new innovations emerge. The massive investments in AI data centers, some expected to span a decade, could be stranded if breakthroughs in algorithms or hardware significantly reduce required resources.
He also stressed that the true disruption in AI likely won’t come from incremental improvements to current models, but rather from a game-changing innovation nobody sees coming. Cuban cautioned smaller AI startups against copying the deep-pocket strategy of tech giants, as they may be less resilient if the bubble bursts.
