BigBear.ai vs. D-Wave Quantum: Which Technology Stock Is a Better Buy in 2026?

August 3, 2026 - 02:42

Investors looking at quantum computing and AI stocks in 2026 have two very different headaches to choose from. BigBear.ai looks profitable on paper, but a recent accounting restatement has shaken confidence. D-Wave Quantum, on the other hand, is still burning through cash, yet it keeps claiming triple-digit revenue growth. Neither is a clean buy, but one might be easier to stomach.

BigBear.ai reported positive net income for the first time in its recent quarter, which sounds great. But that number came after the company had to redo its financials for earlier periods, and the restatement involved how it recognized revenue from a major government contract. That kind of thing tends to make auditors nervous, and it makes future earnings hard to trust. The company also relies heavily on a few large clients, so a single lost deal could wipe out the paper profit.

D-Wave is the opposite story. It loses money every quarter, and its cash reserves are not huge. But its revenue growth is real, driven by sales of its annealing quantum computers and cloud services. The company recently announced a record quarter for bookings, and it keeps signing up commercial customers in logistics and drug discovery. The problem is that growth is expensive, and D-Wave will likely need to raise more capital soon, which could dilute existing shareholders.

So which is the better buy? It depends on your tolerance for risk. BigBear.ai offers a false sense of safety because the profit is fragile and the accounting issues are unresolved. D-Wave offers a clearer story, but it is a cash furnace. For 2026, I would lean toward D-Wave, not because it is a great company, but because its growth is easier to verify. BigBear.ai's numbers are too tangled to trust, and in a market that punishes surprises, that is the bigger risk. Neither stock is for the faint of heart, but if forced to choose, go with the one whose revenue you can actually count.
