Quantum Computing Inc. is premature as an investment and not a serious contender to bring TFLN photonics into the data center. Its billion-dollar roll-up strategy, funded by share issuance, brings a lot of execution risk and management has much to prove. Its Arizona Fab 1 runs as a 150-mm TFLN development and foundry facility preparing to ramp. Direct quantum computing is a mid-2030s story, though government-funded component sellers can earn revenue, so it stays on the watchlist. x.com 

QuantumScape has enormous potential but still a lot to prove, and at a $5B market cap much of the hype is priced in. It never retested $5 and powered through expected resistance near $7.80, so it is a pass for now, despite real long-term potential if the company executes. 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

Infleqtion is the only quantum stock needed, set apart from qubit lottery tickets by real revenue and contracts. Q2 revenue was $13.5M, 2026 guidance was raised to about $43M, it holds a $20M NASA contract for a space gravity sensor, and it is debt-free with hundreds of millions in cash. US government quantum contracts of $300M signal rising sector demand. At under a $3B market cap, it could be the next SanDisk if the quantum trade plays out. x.com 

D-Wave Quantum is pure science fiction with limited application space, and the market will eventually push it below $1. It carries a $6B market cap with no revenue, products or working technology. 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

Quantinuum's IPO adds yet another ridiculously valued company to the quantum sector rather than changing its dynamics. Comparing these companies on technology or business model is like counting angels on a pin. Even Infleqtion trades at 100x revenue and loses a dollar for every dollar of revenue it makes. x.com 

D-Wave Quantum is hard to justify as a $7B company trading at 50x 2028 sales in a highly speculative industry, and its CFO is resigning. x.com 

Trump's executive order for a US quantum computer at a national lab by 2028, with the post-quantum encryption deadline pulled to 2031, makes quantum a strategic industry funded like chips and nuclear. Rigetti, D-Wave and Infleqtion each got $100M with the government as shareholder. IonQ leads on revenue via direct defense contracts, with Q1 revenue up 755% to $64.7M. Quantum Computing Inc is a lottery ticket at ~635x sales; the Defiance ETF is a basket. Backing de-risks science, not valuations. … Show more

IonQ is priced as a story, not a company: with annual revenue under $50 million, its valuation bets on the most optimistic version of quantum computing a decade from now. The market now rewards narrative over earnings and punishes a single missed quarter. That can last a long time when liquidity is ample and risk appetite high, as dot-com stocks in 1999 and SPACs in 2021 showed, so a drop is not imminent. Buyers chasing it are buying how long sentiment lasts, not company value. x.com
