On September 8, 2026, Rigetti jumped about 7% before the open, D-Wave rose over 5% and Quantinuum gained close to 4%. The trigger was a set of finalized Commerce Department deals worth $100 million each, with the government taking minority equity stakes. Even after that pop, both Rigetti and D-Wave still sat well below where they started 2026. So are quantum computing stocks a good buy right now, or is the sector still too early?
I trade narrative sectors in crypto, and quantum stocks behave a lot like early-stage tokens: huge promise, thin revenue and sharp swings. Here is how I weigh the case, and it is my personal view only.
The bull case for quantum computing stocks
There are real reasons for optimism, and they go beyond headlines. Governments see quantum technology as strategic, big companies are testing real applications, and a few firms are finally showing revenue growth that looks like a business rather than a science project.
The strongest argument is backing. In May 2026, the Commerce Department outlined about $2.013 billion in letters of intent across nine quantum companies. Finalized deals in September turned part of that into real funding, which lowers cash pressure for the recipients.
Real revenue is arriving for some names
IonQ reported roughly $80 million in second-quarter revenue and later raised its 2026 outlook to $450 million to $460 million. That shows at least one company can scale sales meaningfully.
Bookings suggest demand is building
D-Wave's revenue is small, but first-half bookings of about $35.5 million point to growing customer interest. Bookings often turn into revenue later, though the timing can be uneven.
The bear case for quantum computing stocks
Most quantum companies still lose money. Government funding also comes with equity stakes, which adds shares and can dilute existing holders. Cash arrives in stages linked to research goals, so missed targets could delay money.
Competition is fierce as well. Tech giants like IBM and Alphabet run large quantum programs with far deeper pockets than any pure-play company, and they can afford to spend through long periods without profit.
Valuations are another problem. Many quantum stocks trade on expectations years into the future. With bond yields hovering around 5% and a Fed hike expected, long-duration growth stories face pressure.
Signals that would make quantum stocks more attractive
I would feel better about the sector if more companies showed steady quarter-over-quarter revenue growth, not just one-off system sales. Clear technical milestones, such as demonstrations of error-corrected qubits at scale, would also strengthen the case.
A calmer macro backdrop would help too. If bond yields drift lower and the Fed signals it is done hiking, speculative growth stocks usually find more buyers.
How I decide whether quantum stocks fit my portfolio
I used Bitget for copy trading for a while, and following others was easy. For a sector this uncertain, I prefer my own small, planned positions. I trade quantum themes through Bitunix, keeping each position a small share of my account.
When I use futures, leverage stays modest and my exit is fixed before entry, because a double-digit daily move in these names can wipe out leveraged margin. A positive headline is never my reason to average into a losing trade. A good story does not fix a bad entry, and averaging down in a volatile sector can turn a small mistake into a large one.
So, are quantum computing stocks a good buy?
For long-term believers, a small, diversified slice may make sense, especially with government backing and rising revenue at the leaders. For short-term traders, volatility creates setups but punishes oversized bets. I treat quantum computing stocks as a speculative position, not a core holding, and your approach may differ.
Interested in quantum but wary of the swings?
The biggest risk in early sectors is sizing like the outcome is certain. Keeping each quantum position small, with an exit decided in advance, lets me stay involved without letting volatility take over.
Start with Bitunix and size your quantum exposure with a plan
Believe in the technology if you like, but size for uncertainty. Quantum computing stocks reward patience more than big, rushed bets.
