{"capturedOn":"2026-09-09","source":"https://www.humansourcer.com/market-data/","license":"https://www.humansourcer.com/ai-training-pay/#license","methodology":"Rate statistics are computed over distinct advertised rates, deduplicated by (provider, pay text), not per listing. Providers replicate one pay sentence across many listings; counting per listing would let a single advertisement vote thousands of times.","findings":[{"id":"rate-spread","question":"How much do advertised rates vary?","statement":"The middle half of advertised AI-training rates falls between $25–$100/hr, but the full range runs from $1 to $400 per hour, with 9.0% of distinct advertised rates below $10/hr and 11.4% at $150/hr or above. Measured over 791 distinct advertised rates, not per listing.","value":"$25–$100/hr","sampleSize":791},{"id":"replication","question":"Why one pay sentence covers a thousand listings","statement":"5,732 listings state an hourly rate, but they carry only 791 distinct advertised rates - each one repeated across 7.2 listings on average. Providers post a batch of roles quoting one pay sentence, so counting per listing would let a single sentence vote thousands of times. Every rate figure on this page is computed over the distinct rates instead.","value":"7.2×","sampleSize":791},{"id":"concentration","question":"How concentrated is this market?","statement":"Across 35 platforms with live listings, the largest single source accounts for 44.2% of indexed listings and the top three for 62.5%, giving a Herfindahl–Hirschman Index of 0.225 - moderately concentrated. This describes the listings HumanSourcer indexes, not the AI-training market itself: a platform that publishes no scrapeable board is absent from it entirely.","value":"0.225","sampleSize":35},{"id":"pay-units","question":"How is pay actually quoted?","statement":"96.3% of listings that disclose pay quote an hourly rate. The other 221 quote per task, per unit, per project or as a salary, and are excluded from every hourly figure on this site - there is no honest way to convert a per-task price into an hourly one without knowing how long the task takes.","value":"96.3%","sampleSize":5953},{"id":"transparency","question":"How often is pay disclosed?","statement":"86.0% of active listings state some pay signal - but that is listing-weighted, and one large source posting thousands of near-identical roles moves it (Prolific Participants alone is the largest). Counted per platform instead, 28 of 35 (80.0%) publish pay on at least one open role.","value":"86.0%","sampleSize":6920},{"id":"country-coverage","question":"Where do listings say applicants must be?","statement":"Of the 3,031 listings whose title names a country (43.8% of 6,920), the most frequently named are USA (36.5%), United Kingdom (21.7%), Canada (6.0%). The remaining 3,889 state no country in their title, which is reported as unknown rather than assumed to be worldwide.","value":"USA","sampleSize":3031},{"id":"turnover","question":"How long do listings stay open?","statement":"Of 666 listings first indexed between 2026-08-26 and 2026-09-02, 41% had closed within 7 days. Only listings whose full 7-day window has elapsed are counted, so a listing posted yesterday cannot drag the figure down; the earlier bound is where closures stop being visible in the published data, so the cohort is a window rather than everything older.","value":"41%","sampleSize":666}],"rateHistogram":[{"lower":0,"upper":10,"count":71,"hedged":25},{"lower":10,"upper":20,"count":82,"hedged":29},{"lower":20,"upper":30,"count":85,"hedged":22},{"lower":30,"upper":40,"count":65,"hedged":14},{"lower":40,"upper":60,"count":98,"hedged":16},{"lower":60,"upper":80,"count":106,"hedged":6},{"lower":80,"upper":100,"count":80,"hedged":6},{"lower":100,"upper":150,"count":114,"hedged":8},{"lower":150,"upper":200,"count":56,"hedged":6},{"lower":200,"upper":null,"count":34,"hedged":5}],"hedgeSplit":{"stated":{"count":654,"median":65},"hedged":{"count":137,"median":25},"hedgedShare":0.1731984829329962},"concentration":{"hhi":0.22482575428514154,"groups":35,"top1Share":0.4421965317919075,"top3Share":0.625},"roundNumberShare":{"multipleOf5":0.7218710493046776,"multipleOf10":0.48419721871049304},"providers":[{"slug":"afterquery-experts","brand":"AfterQuery Experts","openRoles":206,"distinctRates":79,"medianRate":105,"p25Rate":80,"p75Rate":142.5,"disclosedShare":0.9902912621359223},{"slug":"mercor-experts","brand":"Mercor Experts","openRoles":381,"distinctRates":120,"medianRate":90,"p25Rate":60,"p75Rate":140,"disclosedShare":1},{"slug":"handshake-ai","brand":"Handshake AI","openRoles":200,"distinctRates":28,"medianRate":82.5,"p25Rate":58.75,"p75Rate":112.5,"disclosedShare":1},{"slug":"micro1-experts-opportunities","brand":"micro1 Experts Opportunities","openRoles":312,"distinctRates":103,"medianRate":80,"p25Rate":43.5,"p75Rate":120,"disclosedShare":0.9807692307692307},{"slug":"sepal-expert-hub","brand":"Sepal Expert Hub","openRoles":88,"distinctRates":76,"medianRate":75,"p25Rate":60,"p75Rate":92.75,"disclosedShare":0.9772727272727273},{"slug":"rise-data-labs","brand":"Rise Data Labs","openRoles":113,"distinctRates":10,"medianRate":45,"p25Rate":41.25,"p75Rate":50,"disclosedShare":0.7522123893805309},{"slug":"dataforce-jobs","brand":"DataForce jobs","openRoles":153,"distinctRates":8,"medianRate":41,"p25Rate":30,"p75Rate":51.875,"disclosedShare":0.5098039215686274},{"slug":"sme-careers","brand":"SME Careers","openRoles":249,"distinctRates":37,"medianRate":40,"p25Rate":26,"p75Rate":70,"disclosedShare":1},{"slug":"mindrift","brand":"Mindrift","openRoles":145,"distinctRates":13,"medianRate":40,"p25Rate":34,"p75Rate":50,"disclosedShare":1},{"slug":"prolific-participants","brand":"Prolific Participants","openRoles":3060,"distinctRates":58,"medianRate":30,"p25Rate":21,"p75Rate":80,"disclosedShare":0.9509803921568627},{"slug":"meridial","brand":"Meridial","openRoles":831,"distinctRates":58,"medianRate":30,"p25Rate":12,"p75Rate":65,"disclosedShare":0.9927797833935018},{"slug":"turing-ai-advancement-work","brand":"Turing AI Advancement Work","openRoles":227,"distinctRates":7,"medianRate":20,"p25Rate":15,"p75Rate":60,"disclosedShare":0.13215859030837004},{"slug":"welo-data","brand":"Welo Data","openRoles":434,"distinctRates":114,"medianRate":15.5,"p25Rate":8.850000000000001,"p75Rate":29.03,"disclosedShare":0.43317972350230416},{"slug":"telus-international-ai-community-portal","brand":"TELUS International AI Community portal","openRoles":72,"distinctRates":17,"medianRate":15,"p25Rate":6,"p75Rate":25,"disclosedShare":0.9444444444444444},{"slug":"alignerr","brand":"Alignerr","openRoles":60,"distinctRates":1,"medianRate":null,"p25Rate":null,"p75Rate":null,"disclosedShare":1}]}
