White Brook Capital Partners stated the following regarding Rigetti Computing, Inc. (NASDAQ:RGTI) in its third quarter 2025 investor letter:

“There’s a lot of spending across sectors behind AI demand. Everything from electricity and associated generation technologies, to water treatment and pipes have become more expensive to deal with data center cooling needs. In many cases, the associated companies are enjoying stock prices that reflect an exceptionally bullish possible reality. Companies in quantum computing, for example, which is multiple generations of computing standards away, if it’s economically feasible at all, and if it is, may not be appropriate for artificial intelligence use cases, and if it is, may not be better than alternative approaches – trade at elevated multiples of forward revenue estimates. For example, Rigetti Computing, Inc. (NASDAQ:RGTI) is generating a whopping $3 million dollars of quarterly sales and over $15 million of quarterly loss, but enjoying an $18 billion market capitalization. That’s thousands of multiple turns of forward revenue. Calling a bubble is easier today in certain segments than it has ever been.”
