How much does Mercor actually pay?
Mercor is the fastest-growing AI training platform of 2025-2026, focused on high-credential expert data — medicine, law, PhD reasoning. This page tracks Mercor's disclosed hourly rates by domain, sourced from listings on HireFeed.
Mercor pay rates by domain
Mercor's growth is built on high-tier credentialed expert data, so its pay bands skew higher than generalist platforms. Full cross-platform methodology in the Pay Index.
| Domain | Typical range | Top decile | What it involves |
|---|---|---|---|
| Medicine · MD/DO | $100–$210/hr | $250/hr | Clinical reasoning, diagnostic eval, medical Q&A calibration |
| Law · JD | $90–$160/hr | $250/hr | Contract reasoning, compliance analysis, legal writing eval |
| Agentic Evaluation | $70–$130/hr | $160/hr | Tool-use trajectories, red-teaming, adversarial probing |
| Coding Evaluation | $50–$85/hr | $110/hr | Code review, SxS eval, debugging challenges |
| RLHF Annotator | $35–$55/hr | $70/hr | Preference ranking on LLM reasoning outputs |
| Domain Expert · Other | $80–$180/hr | $220/hr | Finance, engineering, specialized science with credential |

What makes Mercor pay differently?
Mercor built its reputation on aggressive top-of-band rates for verified experts, especially in medicine and law. Three things drive the differentiation:
- APEX assessment. Mercor's AI-conducted interview replaces traditional screening. It's rigorous — and once passed, the score attaches to your profile for future project matches.
- Credential verification. Mercor pays for verified credentials (MD via NMC, JD via bar registry, etc.). Unverified applicants sit in lower tiers.
- Take-rate marketplace. Mercor is not a job aggregator — it sells experts to labs at a 30-40% margin. That margin funds the higher published rates, but also means Mercor gates the buyer relationship.
Mercor vs. Outlier — which pays better?
For generalist and coding work: Outlier is often faster to onboard and comparable on rates. For credentialed domain expert work (MD, JD, PhD): Mercor's top-decile rates are higher, but the screening funnel (APEX + calibration) is longer. Neither is universally better — it depends on your credential + timezone + patience with screening.
Anti-pattern: passing 6 different platforms' assessments in 6 weeks. If you're already Mercor-verified, HireFeed Vetted (in build, Q4 2026) is designed to make that credential portable — so you're not re-proving yourself for every new project.
Common questions.
How much does Mercor pay in 2026?
Mercor's disclosed rates range from $35-$55/hr for generalist RLHF annotation up to $100-$210/hr for medical MD work, with top-decile projects reaching $250/hr. Law (JD), agentic evaluation, and specialized domain expert projects fall in between.
Is Mercor's APEX assessment hard?
APEX is Mercor's AI-conducted interview — rigorous, and considered one of the more selective screens in the industry. Mercor reports passing rates around 1% of applicants across the platform. Preparation matters: know your domain deeply and expect follow-up questions on ambiguous scenarios.
Does Mercor pay weekly?
Mercor pays on a project-based cadence with weekly disbursement for approved work. Payment is tied to project acceptance by the underlying buyer (a lab or company), so timing depends on the specific contract.
Can I work on both Mercor and Outlier?
Yes. Most platforms don't restrict cross-platform work as long as it doesn't create a conflict of interest on a specific project. In practice, most AI trainers are on 2-3 platforms simultaneously to smooth out queue variability.
How does Mercor differ from a traditional job board?
Mercor is a marketplace — it screens talent, sells access to that pool to buyer companies, and takes a margin (typically 30-40%). A job board like HireFeed aggregates listings and lets you apply direct to the underlying platform. Different business models, different candidate experiences.
