Open roles, week by week

Is the number of open roles in Law, Medicine & Finance rising or falling?

31 AugPartial week	437	123.2	110.5	437

Sample. Average open roles in Law, Medicine & Finance over each week's days, on the 15 platforms tracked since 3 Aug 2026 (the fixed panel; 13 of them list this work), 3 Aug 2026 to 31 Aug 2026.

The index is the panel's open roles against the week of 3 Aug 2026 (100), beside the same index for all AI training work on the same platforms.

Every platform listing this work in the span was tracked from the start of the series.

Weeks with fewer than 10 open roles on the panel, or cut by the span, are marked.

The series starts in the week of 3 Aug 2026 at the earliest: before it, this dataset's feeds were still being added and tuned.

Listings added and removed

How fast do roles in Law, Medicine & Finance turn over, and is the stock growing on the same platforms?

Work	Open on 1 Aug 2026	Open on 31 Aug 2026, same platforms	Change	New listings	Removed	Median days listed
Law, Medicine & Finance	361	431	+19.4%	314	244	27.5 days
All AI training work	1,520	1,591	+4.7%	938	867	21.6 days

Sample. Roles listed from 1 Aug 2026 to 31 Aug 2026: 675 in Law, Medicine & Finance, 2,458 across all AI training work.

Change compares the roles open on the first and the last day of the window on the platforms tracked when it opened, so a platform added during the window does not read as growth.

A new listing first appeared in the window on a platform already tracked before that week; a platform's first week (its back catalogue) is not counted.

Median days listed runs from a removed role's listing date to its last sighting, for removed roles with a known listing date (at least 10; 235 here).

Sample. 431 roles in Law, Medicine & Finance open at the end of 31 Aug 2026, by the platform that lists them: HHI 2,180 (moderately concentrated), against 1,993 for all AI training work.

HHI: the sum of every platform's squared percentage share of the open roles, 0 to 10,000; under 1,500 is unconcentrated, 1,500 to 2,500 moderately and above 2,500 highly concentrated (US merger-guideline thresholds).

Shares are of listings, not of people hired or money paid: a platform posting one role per language or country weighs more here than its hiring may.

A median needs at least 8 roles stating an hourly rate.

What it pays

What do roles in Law, Medicine & Finance advertise per hour, against AI training work as a whole?

Work	Median per hour	25th percentile	75th percentile	Stating an hourly rate	Roles stating pay
Law, Medicine & Finance	$78	$65	$100	96.5%	416
All AI training work	$65	$40	$85	89.1%	1,418

Sample. Roles open on 31 Aug 2026: 431 in Law, Medicine & Finance, 416 of them stating an hourly rate; 1,591 across all AI training work.

Pay is the hourly figure the posting advertises (the middle of a stated range). The middle half runs from the 25th to the 75th percentile.

Roles paid per task or per project, or that state no figure, do not state an hourly rate. A median needs at least 8 roles stating one.

Sample. Apply clicks on a specific role on AITraining.jobs, from 1 Aug 2026 to 31 Aug 2026: 94 on roles in Law, Medicine & Finance, against the days those roles were open.

Clicks per role a week = apply clicks / (open role-days / 7). Index 1.00 is the rate of every role on the site.

Rows with fewer than 30 clicks or 3 roles open on an average day are marked as a small sample.

Apply clicks measure interest among visitors to AITraining.jobs, who see roles open in their country and recent, priced roles first. Clicks are never split by platform.

Sample. Apply clicks on roles in Law, Medicine & Finance, from 1 Aug 2026 to 31 Aug 2026, by when each role was listed relative to the window's first day (1 Aug 2026).

Listing date: the date the job board gives for the posting, or else the first day the role appeared in the feed. A role that arrived with a platform's back catalogue and gives no date has none.

The index divides each row's rate by the rate of all roles in this kind of work, so it reads within the kind.

Rows with fewer than 30 clicks or 3 roles open on an average day are marked as a small sample.

Sample. 431 roles in Law, Medicine & Finance open at the end of 31 Aug 2026, for residents of a fixed set of 20 countries.

A country's count is the roles open worldwide, plus roles whose list names it, plus roles whose exclusion list does not. Roles with no rule stated count for no country.

The 20 countries are the same in every report of this series: those named most often by the location rules of open AI training roles on 9 Oct 2026, either as the only countries accepted or as excluded.

Median pay is over the roles open to that country that state an hourly rate (at least 8).

A mention can be a requirement or a preference ('a PhD is a plus'): the figure counts both. The patterns are those of the requirements report.

Only some platforms publish full descriptions, so this figure describes their roles, not every platform's.

Method and definitions

The public job boards of the AI training platforms this site tracks, read every day. Apply clicks are made on AITraining.jobs; full descriptions come from the platforms whose boards publish them. Every figure is computed by one database query over the window shown, the same query for the live report and for every edition. Each figure states its sample beneath it.

Kind of work: Each role is classified from its title and description into one of the twelve kinds of AI training work this site tracks; this report counts the roles classified as Law, Medicine & Finance.
Fixed panel: The platforms already tracked when the weekly series opens. The index follows their open roles, so a platform added later (such as OpenTrain AI and Welo Data in September 2026) never reads as growth.
Index: The panel's average open roles in a week, divided by the same in the base week, times 100; shown beside the same index for all AI training work on the same platforms.
Open role: A role listed by a given day and still in its platform's feed that day.
New listing: A role that first appeared during the window on a platform already tracked before that week. A platform's first week in this dataset is its back catalogue and is not counted as new.
Removed listing: A role that left its platform's feed during the window.
Days listed: From a removed role's listing date to the last day it was seen in its feed. A median needs at least 10 removed roles.
HHI: Herfindahl-Hirschman Index: the sum of every platform's squared percentage share of open roles, 0 to 10,000. Under 1,500 unconcentrated, 1,500 to 2,500 moderately, above 2,500 highly concentrated.
Advertised pay: The hourly figure a posting states (the middle of a stated range). Medians need at least 8 roles stating a rate; the middle half runs from the 25th to the 75th percentile.
Clicks per open role a week: Apply clicks on AITraining.jobs on a specific role, divided by the days the roles were open, times 7.
Demand index: Clicks per open role a week divided by the same rate across every role on the site. Above 1, the roles draw more applicants than the average role.
Listing age: When a role was listed relative to the window's first day: during the window, up to 4 weeks before it, 4 to 12 weeks before or longer. The listing date is the job board's posting date, or else the first day the role appeared in the feed.
Location rule: Read from each posting's location text and, where that names no country, from what the posting's own description states: open worldwide, worldwide except listed countries, only listed countries, or no rule stated.
Open to a country: A role is open to residents of a country if it is open worldwide, its list names the country, or its exclusion list does not. The 20 countries compared are the same in every report of the series.
Window: Live: the last 28 complete days, in UTC, and the last twelve complete ISO weeks (from the week of 3 Aug 2026 at the earliest) for the weekly series. Edition: one calendar month, in UTC, and its weeks.

What this data cannot tell you

Platforms that recruit without a public job board are not counted. Several large ones invite workers to projects directly.
A listing is not a hire. Some platforms keep evergreen roles open for months, and some post one listing per language or country.
Apply clicks measure interest among the people who use AITraining.jobs, and what is shown first gets clicked more. Clicks are never published by platform.
Full descriptions are published by a few platforms only, so the requirements figure describes their roles and appears only when at least 10 roles of this kind are described.
A kind of work with few open roles gives figures that move with a handful of postings: rows on too little data are marked as a small sample.

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 covers the last 28 complete days and changes every day. 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.
