D-Wave Quantum (QBTS) trades near $17.50, roughly 61% below its peak from the past year, even as broader markets posted strong gains.
The S&P 500 returned close to 18% over that same twelve-month stretch, making QBTS’s decline all the more striking in context.
The stock has already absorbed a shock-sized drawdown without an actual market shock triggering it, which makes sizing any position forward particularly difficult.
Revenue in the second quarter of 2026 came in at $3.1 million, essentially flat compared with the second quarter of 2025.
The adjusted EBITDA loss for that quarter widened to $37.1 million, a figure 85% larger than a year earlier, with management attributing the increase to accelerated product development and go-to-market spending.
That spending is sitting under a market capitalization of approximately $6.5 billion, meaning almost none of that valuation reflects what D-Wave sells today.
The company has secured real customers in the meantime, including AT&T, which expanded an agreement to apply D-Wave’s technology to network optimization problems, with one early application cutting a process from roughly an hour down to under 15 seconds.
Florida Atlantic University purchased a $20 million annealing quantum computer, contributing to $35.5 million in first-half bookings compared with just $2.9 million a year earlier.
Management expects to ship two systems over the remainder of 2026, both likely landing in the fourth quarter, while gate-model machines remain much further from generating significant commercial revenue.
Two government contracts are already producing initial revenue on those gate-model systems, but management does not expect meaningful revenue from broader access until around the 2032 time frame.
Cash and marketable securities stood at $546.2 million at the end of June 2026, giving the company a meaningful runway to pursue its longer-term strategy.
The operating margin over the trailing twelve months sits near -1,370%, compared with a three-year average of approximately -750%, reflecting how losses are widening relative to revenue.
Across five market shocks since 2022, QBTS fell an average of 51% peak to trough while the S&P 500 declined roughly 13% during those same windows.
The worst single episode was a 73% drop during the yield shock of late 2023, underscoring how severely the stock amplifies broader market stress.
Over its entire trading history, the all-time peak-to-trough drawdown for QBTS reached approximately 97%, and that is the figure most relevant for position sizing decisions.
A position representing one-tenth of a portfolio would shave roughly 10% from total value in such a scenario, while a one-fifth allocation could cut around 20%.
Recovery timelines have generally been swift, with a median of about three months from the trough, though the slowest post-shock recovery after the 2022 inflation episode stretched to approximately 31 months.
The true test of any position size is not how it looks in retrospect but how it feels during the fall, when the payoff remains years out and the price is still declining.
The size that holds up is simply the one where a repeat of past drawdowns produces a loss an investor can endure without abandoning the position.
QBTS is not a stock that falls less than the market when conditions deteriorate, and that reality should anchor every decision about how much exposure to carry.
