How we count disclosed funding
Rankings use total disclosed funding: the sum of publicly reported private rounds, public listings, at-the-market programs and notable state capital injections where reported. Grants and non-dilutive funding count only when they are part of a reported financing package. Amounts prefixed with ~ are approximations, and many rounds — especially in China and at seed stage — are never disclosed at all, so every total understates reality to some degree. That is why figures for the same company can differ by billions across trackers: they are often measuring different things. Confidence levels and limitations are documented on the methodology page.
Funding raised is not valuation
This leaderboard ranks capital raised, not company valuation or market capitalisation. A company valued at several billion dollars but with little disclosed funding sits below a company that has actually raised more. We do not publish valuation-based rankings; for a deal-by-deal view of individual rounds instead, see the funding news timeline.
How often these rankings change
The pipeline scans public news sources daily and rebuilds this page on every update. Newly collected events are marked ⚡ auto until a human verifies them against the source, so the order can move as rounds are confirmed. The date of the latest scan appears in the note below the table, and the same data is available as JSON and RSS for anyone tracking changes.

❓ Frequently Asked Questions
What are quantum computing funding rankings?
A ranking of quantum computing companies ordered by total disclosed funding in USD. This page covers all tracked quantum technology companies — computing, communication and sensing — and lets you filter by region, technology, funding tier and company status.
Which quantum computing company has raised the most funding?
The company in row 1 of the table above currently leads by cumulative disclosed funding. We recalculate the order daily, so the leader can change when a new round is verified. Amounts marked ~ are approximations.
Is this ranking based on funding or valuation?
Funding only. We sum disclosed capital raised — private rounds, public listings and reported state capital injections — not company valuation or market capitalisation. Grants count only when they are part of a reported financing package.
How often are the rankings updated?
The data pipeline scans public news sources daily and rebuilds this page. Newly collected events are marked auto until a human verifies them against the source. The date of the latest scan is shown in the table note.
Can I use the data for free?
Yes. The full ranking is visible without signup, and the underlying datasets are machine-readable JSON licensed CC BY 4.0. See the Methodology page for sources and limitations.
