IonQ or D-Wave in 2026? After the 30%+ Crash, the Better Buy May Be the One with Real Revenue

IonQ still looks more grounded after the recent pullback

After the selloff, IonQ looks like the better buy today because the market is forcing a harder question: do you want current commercial proof, or a cleaner balance sheet under a more speculative story? Both stocks have already taken a hit-IonQ down 37% and D-Wave down 28% over the past month-so the dip has done some filtration. What remains is a choice between a company building a revenue base and one asking investors to underwrite technical hope.

IonQ now reads more like a business investors can track quarter to quarter. It posted $64.7 million in Q1 revenue, up 755% year over year, and ended the quarter with $470 million in RPO. That gives the stock visible operating leverage if bookings convert, and it also has over $100 million in Air Force Research Lab contracts plus deeper active government work.

D-Wave is not broken; it is just earlier. Q1 revenue was only $2.9 million, even as the company held $588 million in cash. Bulls will point to record bookings of $33.4 million and argue commercial adoption is starting. Maybe. But right now, IonQ has the stronger alignment of interest because it is converting demand into reported sales, while D-Wave still needs investors to believe future adoption will scale faster than execution risk can disrupt it.

IonQ's case is increasingly about execution and customer mix

What matters now is not just that IonQ grew fast. It is that the quarter looked more like a real business taking shape.

Commercial demand is becoming easier to see

About 60% of revenue from commercial customers and 35% from international customers changes the read on demand. That is not a small-set pilot story. It suggests customers outside government are allocating budget, and they are doing so across geographies.

That is also why booked demand matters more than near-term profitability. In a company this early, profits can be bought by slowing growth, but backlog is harder to fake. IonQ ended the quarter with RPOs up 554% year over year to $470 million, while management also pointed to a growing backlog. That combination suggests customers are committing to deliveries and integrations rather than just running short tests.

The trade-off is still spending

The bear case is straightforward: IonQ is still spending heavily. In its Q1 update, management described the strongest quarter ever, but the company is still in a heavy-investment phase as it scales product, delivery, and infrastructure. That is the trade-off: the spending may be buying durability, but it also leaves little room for delivery slips or slower conversion from backlog to shipped revenue.

If shipments and customer adoption keep building, current losses may matter less than the quality of the demand underneath them. If execution wobbles, though, the stock loses much of its best defense.

D-Wave has a cleaner product arc, but the revenue base is still thin

If D-Wave is the counterpunch, its best case is not "cheap quantum hope." It is a cleaner product arc: the company can sell near-term annealing value while still presenting a future gate-model path. That is why the stock still deserves attention after the pullback.

The strongest case for D-Wave

Bulls have a real argument here. D-Wave is positioning as the only dual-platform quantum computing company, offering both annealing and gate-model systems, plus associated software and services. That matters because annealing can commercialize first, while gate-model work preserves more long-dated option value.

The quarter's demand signal was also hard to ignore. D-Wave reported Record Quarterly Bookings of $33.4 million, up nearly 2,000% year over year. Combined with its product narrative, that gives bulls a case that D-Wave may be earlier on revenue but broader in its market story.

Q1 revenue still looks too small to anchor the thesis

For public-market tracking, Q1 was a weak reveal. D-Wave reported just $2.9 million in Q1 revenue, down from $15.0 million a year earlier. Management's explanation is defensible: the prior-year figure included a one-time $12.6 million system sale. Even so, investors still need to see booked demand turn into a steadier sales stream.

The spending profile also widened. D-Wave reported an operating loss of $54.7 million on operating expenses of $56.5 million in Q1. Yes, the company ended with $588 million in cash. That buys time, but time is not the same as proof.

How to position either stock in 2026

For 2026 positioning, IonQ looks like the better base-case holding, while D-Wave remains more of a watchlist name. D-Wave's dual-platform story could rerate faster than fundamentals if bookings begin to normalize into recurring enterprise revenue, but that still has not happened yet.

What to watch next

IonQ - Does the huge backlog convert into shipped revenue, or does it stay as promise? The key signal is whether remaining performance obligations start showing up as repeatable delivery momentum rather than a distant funnel. - Is management getting more disciplined as it scales, or does spending continue to outrun monetization? - Will the customer mix stay balanced? The recent emphasis on commercial customers matters because it is the best evidence that demand is broadening beyond a small set of anchor buyers.

D-Wave - Do the record quarterly bookings turn into sustained revenue growth quarter after quarter? - Or does the company post another thin revenue print alongside a wider loss? - Can the annealing business keep scaling while the gate-model roadmap continues to progress without consuming too much cash for too long?

What would change the call

IonQ's edge weakens if backlog conversion stalls, the commercial mix fades, or losses stay too wide for too long. D-Wave takes over the lead only if bookings normalize into real revenue, not just headlines around the roadmap. The background risk is that commercial maturity may take up to 10 years, so both names should still be treated as high-volatility quantum trades rather than settled winners.

Right now, the better buy is the company with more customer money committed today, because revenue proof and backlog conversion matter more than excitement around a future roadmap.
