Rigetti Computing (RGTI): Valuation Check as Big Investors Turn Cautious on Pure-Play Quantum Stocks

Simply Wall St·01/04/2026 20:30:25
Listen to the news

Rigetti Computing (RGTI) is back in focus after fresh commentary from top hedge funds underscored growing skepticism toward pure play quantum stocks, even as the company pushes ahead with ambitious hardware and cloud roadmaps.

See our latest analysis for Rigetti Computing.

That skepticism is now being reflected in the tape, with Rigetti’s 90 day share price return of minus 43.42 percent and 30 day share price return of minus 16.04 percent signalling fading momentum, even as its 3 year total shareholder return above 3,000 percent reminds investors how quickly sentiment can flip around emerging technologies at a 23.6 dollar share price.

If this quantum volatility has your attention, it might be worth seeing what else is gaining traction among innovative chip and AI names via high growth tech and AI stocks.

With analysts still seeing nearly 50 percent intrinsic upside and the stock sharply off recent highs, is Rigetti now trading below its true potential, or is the market already factoring in years of anticipated quantum growth?

Price-to-Book of 20.9x: Is it justified?

Rigetti’s latest close at 23.60 dollars comes with a steep price-to-book ratio of 20.9 times, signalling a market valuation far above balance sheet equity and sector peers.

Price to book compares a company’s market value to its net assets. It is a common yardstick for hardware intensive, capital heavy semiconductor and quantum computing players where tangible investment is substantial.

At 20.9 times book value versus roughly 3.9 times for the broader US semiconductor group and 7 times for close peers, investors are clearly paying up for Rigetti’s forecast rapid top line expansion and long dated quantum opportunity, even as the company remains deeply loss making and is not expected to turn profitable within the next three years.

That premium, over five times the wider industry norm and roughly triple peer averages, highlights just how far expectations have already stretched relative to current fundamentals, leaving little margin for execution missteps as the story develops.

Result: Price-to-book of 20.9x (OVERVALUED)

However, sustained losses and slower than expected quantum adoption, particularly from cautious government and enterprise customers, could quickly unwind today’s premium valuation.

Another View on Rigetti's Valuation

While that 20.9 times price to book looks stretched, our DCF model paints a very different picture. It suggests RGTI may be trading roughly 48 percent below its estimated fair value of 45.43 dollars per share. Is the market underpricing long term quantum cash flows, or overrating today’s balance sheet risks?
