The bottom line, by the numbers: two speculative technology names now sit almost level on revenue, and miles apart on almost everything else. A Motley Fool comparison published on October 7, 2026, lays out fiscal 2025 for BigBear.ai and IonQ, and the contrast is stark. IonQ booked revenue just under $130.0 million, up about 201.9% year over year. BigBear.ai came in near $127.7 million, down roughly 19.3%. Both lost money, and a lot of it: IonQ’s net loss ran to $510.4 million, BigBear.ai’s to $293.9 million.
BigBear.ai: Sticky Contracts, One Big Customer
BigBear.ai sells decision-intelligence software, mainly to U.S. defense and intelligence agencies. That niche is defensible and its contracts are sticky, but the concentration is severe: customers accounting for more than 10% of sales represented 51% of total revenue. The company’s net margin sat at roughly -230.2%, and it burned $46.3 million of free cash. The balance sheet is clean, with a debt-to-equity ratio of 0.0x and a current ratio near 1.8x. Momentum has improved lately, with the most recent quarter returning to growth, more than 20 new contract wins and expanding margins. The Fool piece also flags reputational drag from material accounting errors and pending class action lawsuits, plus dependence on cloud infrastructure rented from Amazon and Microsoft.
IonQ: Growth Now, Profit Later, Maybe
IonQ builds trapped-ion quantum computers and rents access through a cloud service model, aiming at problems in drug discovery and financial modeling beyond classical machines. Its net margin was about -392.6%, reflecting the cost of developing early-stage hardware, and free cash flow was negative to the tune of $299.6 million. Liquidity is deep, with a current ratio around 15.5x and no debt. The risks are competition from Intel, IBM and Microsoft, technical execution, and likely future financing that could dilute shareholders.
What Investors Will Note
Neither stock has a meaningful forward earnings multiple, so the market is pricing sales: BigBear.ai trades at 9.7 times revenue against 66.3 for IonQ. On the day of publication the market had its own view, with IonQ shares at $32.62, up 23.42%, against a flat $2.22 for BigBear.ai, and market caps of $14 billion versus $1.1 billion. The author’s verdict favors IonQ, citing a customer base spread across government, enterprise and international buyers plus a SkyWater manufacturing partnership, while conceding BigBear.ai’s recent progress. The figure that matters for both, though, is identical: no profits yet, and no guarantee of when.
