Market warnings emerge as AI and semiconductor stocks show signs of a bubble

Bob Elliott, CEO of Unlimited Funds, warns that investor enthusiasm for AI and semiconductor shares may be fueling a bubble, prompting concerns over sustainability amid soaring valuations and speculative activity in the sector.

Bob Elliott, chief executive and chief investment officer of Unlimited Funds, said markets are showing signs of excess as enthusiasm for artificial intelligence and semiconductor shares fuels what he described as “classic bubble-type activity”. Speaking in a Bloomberg video on August 6, Elliott argued that investor fear of missing out is driving prices higher while leverage across markets has also reached levels that worry him.

His comments add to a wider debate over whether the AI boom represents a durable industrial shift or a speculative rush layered on top of genuine technological change. DayTrading.com has noted that artificial intelligence is already reshaping parts of the economy, but also pointed to elevated valuations and speculative capital as signs that some investors may be getting ahead of fundamentals. The article argued that the most resilient opportunities may be found in profitable businesses tied to AI infrastructure rather than in the most exuberant parts of the trade.

Elliott’s scepticism also echoes earlier reporting that Elliott Management has questioned the sustainability of heavy corporate spending on Nvidia’s graphics processing units. Investing.com reported that the hedge fund has called AI “overhyped” and said Nvidia’s stock looks like a bubble, while Data Center Dynamics and Fortune similarly described the firm as warning that major technology shares are in “bubble land”. Those concerns centre on whether demand for AI hardware can remain strong enough to justify the scale of investment now flowing into the sector.

Blockworks has also highlighted a broader “everything bubble” argument, with critics warning that vast sums are being poured into data centres and chips before businesses have proved they can deploy AI profitably at scale. That view does not deny AI’s long-term potential, but it suggests the current market may be discounting too much success, too soon. Elliott’s warning fits that reading: the technology may be real, but the price being paid for exposure to it may no longer be.
