Most pure-play quantum computing companies are pre-revenue and burn cash every quarter, so the single most important question for investors is: how long can each one last before it must raise money (and dilute shareholders)? This page ranks all 10 quantum stocks by cash runway — the number of months of cash left at the current burn rate — using a Yahoo-Finance-aligned, current-assets-only methodology sourced from SEC EDGAR filings.
Which quantum computing company is running out of money first?
As of the latest filings, Arqit Quantum (ARQQ) has the shortest cash runway among pure-play quantum stocks at roughly 15mo of cash at its current burn rate.
How is quantum stock cash runway calculated?
Runway (in months) = current cash and short-term investments ÷ trailing-twelve-month operating cash burn × 12. We use a current-assets-only cash definition aligned with Yahoo Finance, sourced from SEC EDGAR 10-K/10-Q/20-F filings. Companies with positive operating cash flow are marked "CF+".
What is a "going concern" warning?
A going-concern flag means the company’s own auditors have expressed substantial doubt about its ability to continue operating for the next 12 months without raising additional capital — a key dilution-risk signal for investors.
