Quantum computing stocks are entering a more demanding phase in the second half of 2026, with investors shifting focus from qubit milestones to revenue visibility and commercialization.
After a powerful rally earlier in the year, the macro backdrop has become less favorable for high-risk growth stocks across the quantum computing sector.
The Federal Reserve held the federal funds target range at 3.5%-3.75% at its July 29 meeting, even as inflation remains stubbornly elevated above its 2% target.
According to the BLS July CPI report, the Consumer Price Index rose 3.4% year over year, with core CPI up 2.5% and the energy index climbing 14.7% over the 12 months ending July.
The labor market is also showing signs of strain, with July nonfarm payrolls declining 23,000 and unemployment sitting at 4.1%, according to the BLS Employment Situation Summary.
The BEA’s latest Personal Income and Outlays report showed the personal consumption expenditures price index rising 3.7% year over year in June, with core PCE up 3.3%.
July Producer Price Index rose 4.7% year over year, adding further evidence that cost pressures remain elevated across the broader economy.
Reuters reported on August 21 that the 30-year Treasury yield remained around 5.25%, as investors weighed fiscal deficits and a U.S. debt load that has surpassed $40 trillion.
For quantum computing stocks, the message is clear: technological promise alone is no longer sufficient, and investors want evidence that bookings and partnerships can translate into scalable commercial revenue.
IonQ (IONQ) delivered an impressive 287% year-over-year increase in its second-quarter revenues and raised its 2026 revenue outlook to $280-$290 million, but its valuation remains stretched amid continued heavy investment following its SkyWater acquisition.
IONQ currently carries a Zacks Rank #4 (Sell), reflecting near-term execution concerns despite the company’s strong headline revenue growth figures.
D-Wave Quantum (QBTS) faces a different challenge, with first-half bookings surging 1,120% year over year while second-quarter revenue came in at only $3.1 million, essentially flat from a year earlier.
That disparity highlights the sector’s central bottleneck: converting bookings, pilots and technical advances into recurring revenue at scale remains elusive for many players.
QBTS also carries a Zacks Rank #4 at this time, as the gap between ambitious long-term opportunity and near-term financial execution continues to weigh on sentiment.
Washington is maintaining strong support for the sector, with a June 22 White House executive order calling for a national effort to develop powerful quantum computers and accelerate commercial applications.
The Department of Energy subsequently launched its Quantum Genesis initiative targeting scientifically relevant, fault-tolerant quantum computing, further reinforcing the government’s long-term commitment.
Government backing, however, does not eliminate execution risk, as hardware scaling, error correction, manufacturing and customer adoption remain significant bottlenecks across the industry.
Quantum Computing Inc. (QUBT) stands out with second-quarter 2026 revenues jumping to $5.6 million from just $61,000 a year earlier, while its contract backlog reached approximately $42.5 million.
The company also completed its NHanced Semiconductors acquisition and delivered its Dirac-3 quantum optimization system to a global consulting firm, adding diversification across photonics, semiconductors and optimization.
QUBT carries a Zacks Rank #3 (Hold), with six analysts setting an average price target of $18.33, representing a potential upside of 125.2% from its last closing price of $8.14.
Quantinuum (QNT) reported second-quarter revenue growth of 279% year over year and raised its 2026 revenue outlook to $28-$32 million, while year-to-date bookings reached $81 million.
The company’s Helios system demonstrated near-five-nines logical fidelity, and its planned integration with Oracle Cloud Infrastructure opens additional pathways for enterprise adoption.
With more than $2 billion in cash, cash equivalents and short-term investments following its IPO, QNT holds substantial resources to fund its continued development trajectory.
QNT also carries a Zacks Rank #3, with 12 analysts setting an average price target of $97.17, representing a potential upside of 77% from its last closing price of $54.90.
