Revenue and Scale of AI Training Data Companies

Method and definitions

Annual reports, quarterly results and regulatory filings of the listed companies; statements and press reports for the private ones, each linked beside its figure. Every row links the publication it is taken from, with the figure as that publication states it; nothing is estimated or converted. Each figure states what it includes beneath it.

Revenue

What a listed company reports for the period in its filings or results release, in US dollars as reported.

Run-rate and annualised revenue

A recent month or quarter of revenue multiplied out to a year, as a private company or the press states it. Not a year's revenue, and not comparable with reported revenue.

Stated or reported

Stated: the company or a filing gives the figure. Reported: an outlet reports it from unnamed sources.

Workforce claim

What a company says about the people on its platform (contributors, experts, countries, payouts), as it says it. A registered contributor is not an active worker.

What this data cannot tell you

• Compiled from public sources: an event that was never announced or reported is missing, and private companies' figures are what they or the press stated, not audited.
• Fiscal years differ between companies, and a listed company's revenue includes work beyond AI training data.
• Workforce and payout figures are the companies' own and are rarely defined or audited.

How the job feeds are read and roles are classified: site methodology. How fresh, complete and consistent the data is, checked every day: data quality and coverage.

Editions

The live report is the dataset as last reviewed; new events are added as they are published. Each complete month is also published as an edition, frozen two days after the month ends, so a figure you cite from an edition never moves.
