Key findings

  1. 1

    Between the week of 3 Aug 2026 and the week of 24 Aug 2026, open roles in Math & STEM on the platforms tracked since 3 Aug 2026 went up 10.8%, from about 147 to 163, against +9.0% for all AI training work on the same platforms.

    Figure 1
  2. 2

    9 platforms listed the 158 open roles in Math & STEM; Invisible held 47.5% and the three largest 82.3% (HHI 3,001, highly concentrated, against 1,993 for all AI training work).

    Figure 3
  3. 3

    151 of the 158 open roles in Math & STEM (95.6%) stated an hourly rate, with a median of $65/hr (middle half $65 to $85), about the same as the $65/hr of all AI training work.

    Figure 4
  4. 4

    Each open role in Math & STEM drew 0.06 apply clicks a week on AITraining.jobs, 0.80x the average AI training role: the 3rd lowest of 7 kinds of work with enough clicks to rank.

    Figure 6
  5. 5

    37.3% of the 158 open roles in Math & STEM accepted applicants from any country, against 51.3% of all AI training roles; of the 20 countries compared, residents of the United States (102), then India (95), then Indonesia and the Philippines (85 each) could apply to the most, and residents of 6 of the countries (among them Chile and Ghana) to the fewest (59 each).

    Figure 9
  6. 6

    49.4% of the 158 open roles in Math & STEM name an expert field in their title, 14 expert fields in all; Mathematics & statistics (26), Biology & life sciences (15) and Chemistry (12) were named most.

    Figure 10
  7. 7

    Of the 34 open roles in Math & STEM with a full description, 55.9% mention a PhD or master's degree, 29.4% a professional credential and 47.1% an assessment or test; the 10 stating years of experience ask for a median of 2 years.

    Figure 11
  8. 8

    Over the 31 days from 1 Aug 2026 to 31 Aug 2026, open roles in Math & STEM on the platforms tracked at its start went up 6.0% (149 to 158): platforms listed 67 new roles and removed 58, and a removed role had been listed for a median of 36 days (22 across all AI training work).

Sample. Average open roles in Math & STEM over each week's days, on the 15 platforms tracked since 3 Aug 2026 (the fixed panel; 12 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.

Sample. Roles listed from 1 Aug 2026 to 31 Aug 2026: 216 in Math & STEM, 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; 55 here).

Sample. 158 roles in Math & STEM open at the end of 31 Aug 2026, by the platform that lists them: HHI 3,001 (highly 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.

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: 44 on roles in Math & STEM, 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 Math & STEM, 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. 158 roles in Math & STEM 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).

For labs, data vendors and researchers

Buy the data behind this report

The figures above are a summary. Behind them are records we collect ourselves, every day:

  • 9,572 roles tracked, each with its history

    Every role on 29 job boards, read daily since 13 Jul 2026: its pay and place, and the first and last day it was open.

  • 6,200 apply clicks in 28 days

    Which roles people actually apply to, by field, pay and kind of work. It happens on this site, so nobody else can count it.

  • 39 lab and vendor hiring boards

    The job boards of 25 AI labs and 14 human-data vendors, read every day: who is hiring for human data, and who is hiring to buy it.

What you can buy

  • The records

    The rows behind any figure, with their history, not only the totals.

  • A regular feed

    The same figures every week or month, as files.

  • A custom cut or benchmark

    Your countries, languages or fields, or your own platform against the market.

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 Math & STEM.
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.
