Rigetti Computing's valuation is absurd: it still carries a market cap above $5bn on just $5m of revenue and a $28m operating loss. x.com 

IonQ, D-Wave and Rigetti look like traps after spiking on US government equity stakes. The $2B attached to nine quantum companies is roughly $100M each, a rounding error that doesn't change whether the businesses work. D-Wave's last quarter brought in $2.86M of revenue and Rigetti $4.4M, about 600x revenue. Much of the pop was a short squeeze, not revaluation, and the group later fell 7-9% on no news. Unlike Intel, which the government bought cheap, these are bought on a story. x.com 

Quantum computing is a race whose winners get pricing power over the hardest problems; Google's CEO says quantum is where AI was five years ago. IonQ leads with Q2 revenue of $80.1 million, up 287%. D-Wave alone is in commercial production; Rigetti grew revenue 173%. IBM targets fault tolerance in 2029, Alphabet's Willow began the cycle, Xanadu is photonic, Infleqtion has federal backing, Quantum Computing Inc. is speculative, Arqit sells post-quantum security; an ETF holds the field. x.com  … Show more

Rigetti Computing and Infleqtion are too speculative to own because neither has a moat yet. Bernstein flags both as high risk-reward quantum plays, but its own note says it is far too early to declare a winner and that different modalities have distinct strengths, so a new architecture could make their hardware obsolete. Quantum is also highly capital-intensive: Rigetti's roughly $590 million in cash is a runway being burned, not operating profit. For a quality investor, both are a pass for now. … Show more

Rigetti shareholders face $100M of dilution from a Commerce Department deal that is expected to take an equity stake when the company is not lacking funding. The letter of intent provides up to $100M over three years under the CHIPS Act for superconducting quantum R&D. x.com 

Quantum computing stocks D-Wave Quantum, Rigetti and Infleqtion now trade on fiscal support rather than technology: in May 2026 the US government put about $2 billion into the sector and took equity stakes as a condition, sending the three up roughly 30-33% in a day. Positions should be sized like lottery tickets. x.com 

D-Wave Quantum's $5.2 billion valuation, or 325 times revenue, leaves substantial downside against just $1.50 per share in cash. The stock still has an estimated 80% downside. x.com 

Rigetti Computing is far less capitalized and technologically advanced than superconducting rivals IBM and Google, which spend more on R&D than Rigetti's entire market cap. Its chiplet design looks more like useful IP for an acquirer than a sign it will outperform them. Bulls citing 99.9% fidelity overlook that this level is useless for quantum computing, and the bull case rests on blind faith rather than capital or buildout. x.com  x.com 

Quantum computing stocks such as IonQ, Rigetti, Quantum Computing Inc, Arqit, SEALSQ, BTQ and HQ could catch a bid around Quantinuum's IPO. Quantinuum is raising about $1.46 billion at a roughly $14 billion valuation, the first traditional IPO of a full-stack quantum company, anchored by long-only demand. Big IPOs reprice whole sectors as allocators who missed the deal seek liquid exposure, as with Cerebras and SpaceX. The driver is positioning, not fundamentals, so these are very risky trades. … Show more

Honeywell's Quantinuum stake is very underpriced when weaker quantum names like Rigetti and Quantum Computing are bid up to multi-billion valuations. Quantinuum is the best asset in quantum and just raised at $10bn from Nvidia, yet Honeywell trades at 18 times earnings, with Elliott as activist and leverage to robotics over two to three years. Standalone quantum valuations may be wrong, but Honeywell has scarcity value as one of few institutionally investable quantum names besides IBM. x.com  … Show more
