QUBT’s Revenue Is Finally Growing — but Operating Costs Are Growing Even Faster

Quantum Computing Inc. is beginning to show meaningful revenue growth, but profitability remains the central question for investors. Second-quarter 2026 revenue reached $5.6 million, up sharply from just $61,000 a year earlier and from $3.7 million in the first quarter.

The improvement is significant because one of the biggest criticisms of publicly traded quantum companies has been the gap between market capitalization and commercial revenue. QUBT is now producing more sales, but the cost structure is expanding quickly at the same time.

Operating expenses reached $21.8 million, more than double the $10.2 million reported in the prior-year quarter. Higher headcount, research and development, sales and marketing, and acquisition-related expenses all contributed to the increase. The company still posted a net loss of $11.8 million, although that was a substantial improvement from the $36.5 million loss a year earlier.

Liquidity is not an immediate constraint. QUBT ended the quarter with about $1.3 billion in cash, cash equivalents and investments. It also reported a contract backlog of $42.5 million. That combination gives management significant runway to invest in technology and commercialization.

The challenge is capital efficiency. A large cash balance can support years of development, but it does not automatically create shareholder value. Investors need to see revenue scale faster than operating expenses over time.

Peer results show the same tension across the sector. Rigetti generated $5.1 million of quarterly revenue, up 185.3% year over year, while D-Wave reported about $3.1 million. D-Wave’s remaining performance obligations increased sharply, suggesting future revenue visibility, but the sector as a whole is still operating at relatively small commercial scale.

QUBT’s share-price performance reflects that skepticism. The stock had fallen 47.4% over the prior year compared with a much smaller decline for the broader industry measure cited in the source. The market is effectively asking for evidence that rapid percentage growth from a tiny base can become a durable business.

Backlog conversion is therefore one of the most important metrics. If the $42.5 million backlog turns into recognized revenue on schedule, QUBT can begin to demonstrate commercial traction. If backlog grows without conversion, investors may become more cautious about the quality of demand.

The company has financial resources and improving revenue, which are real positives. Profitability remains the missing link. The next stage of the story is not simply growing sales; it is showing that each new dollar of revenue requires proportionally less incremental spending than the one before it.

The size of the cash balance also changes the risk profile relative to smaller peers. QUBT has time to invest through setbacks without immediately returning to capital markets. The danger is that abundant liquidity can reduce urgency around cost control. Investors should therefore pay close attention to whether management sets clear revenue and margin milestones for the spending program.

If backlog conversion accelerates while expense growth moderates, the market can begin valuing QUBT on operating momentum rather than liquidity alone.
