Why I Wouldn't Touch Quantum Computing Stock With a 10-Foot Pole

Quantum Computing Inc. (NASDAQ: QUBT) pursues a differentiated room-temperature quantum computing approach and holds a sizable liquidity cushion — over $1.5 billion in cash and investments — but remains a research-stage firm with Q3 2025 revenue of $384,000 and less than $1 million in trailing‑12‑month sales. Management plans to resolve technical issues and scale production over the next three years, yet the stock carries material execution risk, acute competition from firms already scaling (including foundry-experienced players such as Intel) and the prospect of further shareholder dilution from rapid share issuance; the author advises watching from the sidelines until the company shows clear commercial traction.

Analysis

Quantum Computing Inc. (QUBT) pursues a differentiated room-temperature quantum computing architecture and entered the period with a strong liquidity position—over $1.5 billion in cash and investments—while remaining a research-stage company with Q3 2025 revenue of $384,000 and trailing-12-month sales under $1 million. Management's stated plan is to resolve technical issues and not scale production for roughly three years, indicating the company is currently focused on testing and prototype delivery rather than commercial manufacturing. This timetable creates material execution risk because scaling fabrication is hard, and competitive risk is acute: several players, including foundry-experienced firms such as Intel, are already progressing toward scaled production. The balance sheet strength is partly the result of repeated equity issuance; outstanding share count has been rising and the company may need additional capital over the next three to five years, implying further potential dilution and pressure on shareholder value, so the author recommends monitoring commercial traction before committing capital.

Key Decisions for Investors

• Avoid initiating a meaningful long position until QCi demonstrates commercial revenue growth or concrete production milestones, given Q3 2025 revenue of $384,000 and TTM sales below $1 million
• Monitor KPIs closely: quarterly revenue progression, prototype-to-production timeline, announcements of manufacturing/foundry partnerships, cash burn versus the $1.5 billion cash balance, and changes in outstanding share count to assess dilution risk
• If taking a speculative position, limit size to a small, clearly defined portion of capital and reassess upon demonstrable scaling progress or signs competitors are unable to commercialize faster
