Cerebras Systems vs. Rigetti Computing: Is an AI or Quantum Computing Stock the Better Buy in 2026?

Cerebras Systems and Rigetti Computing represent two different computing frontiers. Cerebras dominates AI hardware with $510M in revenue and 76% growth, while Rigetti pursues quantum computing with only $7.1M in revenue but significant government backing. The article recommends Cerebras as the better 2026 buy due to its established business base, clear growth trajectory, and more reasonable valuation despite both stocks being speculative.

IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. Are Sending Shockwaves Through Wall Street With This $895 Million Warning

Despite quantum computing stocks soaring up to 1,820% over two years, insiders at IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. have collectively sold $895.1 million more shares than they've purchased while barely buying any stock. The companies trade at extreme valuations (P/S ratios of 55.7 to 494.1), suggesting a potential bubble similar to past technology cycles.

Rigetti Turned $10,000 Into Over $81,000 in 3 Years -- and It's Still 73% Off Its High. Here's Why I Still Wouldn't Touch It.

Rigetti Computing stock has delivered exceptional returns over three years despite being down 73% from its peak, driven by quantum computing sector optimism. However, the analyst warns against investing due to the company's extreme volatility, unprofitable operations ($28.1M operating loss on $5.1M revenue), significant cash burn ($32M in H1), and sky-high valuation of 375x sales, making it unsuitable for investors seeking portfolio stability.

IonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge?

IonQ and Rigetti Computing are pursuing different quantum computing technologies with distinct trade-offs. IonQ uses trapped-ion technology with superior accuracy (99.3-99.5% fidelity) and all-to-all qubit connectivity, while Rigetti uses superconducting qubits with faster operations (60 nanoseconds vs. 950 microseconds) but lower accuracy (99.1% fidelity). IonQ currently holds the technology edge with demonstrated error-correction progress and DARPA Stage B advancement, but its lead is not secure as both companies face challenges scaling their systems while maintaining performance.

What It Would Take for IonQ Stock to Reach $100

IonQ is expanding beyond quantum computing into a broader technology platform and raised its 2026 revenue outlook by 60%, with most growth coming from non-quantum segments. However, reaching a $100 share price will require the company to demonstrate recurring demand, improve economics, and successfully scale its full-stack strategy into commercial viability.

Why CoreWeave Stock Soared 12% Today

CoreWeave shares gained 12% today despite no company-specific news, benefiting from a broader rally in the AI infrastructure sector. The gains were driven by Nebius's partnership announcement with Palantir, Department of Commerce investments in quantum computing companies, and Intel's processor price increase announcement. CoreWeave remains a volatile, high-risk stock with rapid revenue growth but massive losses due to heavy capital expenditures and debt servicing.

Why D-Wave Quantum Stock Popped Today

D-Wave Quantum received up to $100 million in funding from the U.S. Department of Commerce under the CHIPS and Science Act, causing its stock to rise 10.86%. However, the government also awarded similar $100 million grants to rival quantum companies Quantinuum and Rigetti Computing. GlobalFoundries received the largest award at $375 million, suggesting it may be the government's preferred champion rather than D-Wave.

Why Rigetti Computing Popped Today

Rigetti Computing's stock surged up to 12.2% after securing $100 million in CHIPS Act funding from the Department of Commerce to advance superconducting quantum computing research. The government will receive a minority, non-controlling equity stake in the company. While the funding is a positive development for the quantum computing sector, Rigetti remains speculative as it generates minimal revenue ($5.1 million in Q2) and quantum computing is still an emerging technology.

Why I Wouldn't Touch IonQ, Even With Quantum Computing Stocks Soaring

Despite IonQ's impressive 287% year-over-year revenue growth and record quarterly results, analyst Matt DiLallo advises against investing in the quantum computing stock due to its massive losses (operating costs 5x revenue), rich valuation (55x forward sales), and high volatility. He suggests considering quantum computing ETFs instead as a safer way to gain sector exposure.
