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

Investors searching for high-growth potential often look toward the frontiers of computation. Comparing BigBear.ai (NYSE:BBAI) and D-Wave Quantum (NASDAQ:QBTS) requires weighing established government contracts against the nascent potential of quantum computing.

BigBear.ai focuses on decision intelligence software for federal agencies, while D-Wave Quantum builds the hardware and cloud platforms for next-generation quantum processing. Both companies represent speculative plays in the tech sector, though they operate at different ends of the computational spectrum. This comparison explores which firm offers a more sustainable path forward.

BigBear.ai provides artificial intelligence solutions to the defense and intelligence sectors, specializing in decision intelligence for government agencies. In its latest annual report, filed for FY 2025, the company noted that the U.S. government accounted for nearly 51% of total revenue. This high level of customer concentration adds significant risk to the business model since it relies on specific federal funding cycles.

In FY 2025, revenue reached nearly $127.7 million, representing a decline of approximately 19.3% compared to the previous year. The company reported a net loss of roughly $293.9 million for the same fiscal period. This resulted in a net margin of nearly -230.2%, indicating that operating expenses far exceeded total sales during the year as the company adjusted its contract mix.

As of its December 2025 balance sheet, the debt-to-equity ratio was nearly 0.0x, indicating the firm carries negligible debt relative to shareholder equity. The current ratio, which measures the ability to pay short-term obligations using current assets, was roughly 1.8x. Free cash flow, or cash from operations minus capital spending, was nearly negative $46.3 million, and the firm maintains its position among cheap tech stocks while adhering to cybersecurity standards.

D-Wave Quantum is a pioneer in quantum computing, offering systems and cloud services to commercial and government clients. Its Leap platform allows businesses to access quantum processing power for logistics, drug discovery, and financial modeling through a cloud-based interface. The company works with high-profile organizations such as Mastercard (NYSE:MA), Pfizer (NYSE:PFE), and Siemens Healthineers (OTC:SEMHF) to build its ecosystem.

In FY 2025, revenue reached approximately $24.6 million, which is a significant increase of nearly 178.5% year over year. Despite this rapid growth, the company reported a net loss of roughly $355.1 million. This led to a net margin of approximately -1,444.1%, highlighting the high costs associated with scaling a commercial quantum provider and developing proprietary hardware.
