Mercor Data Breach Claim: How to Check If You’re Owed, Free

What is the Mercor Data Breach Claim about?

In late March 2026, AI training startup Mercor was hit by a supply-chain attack on LiteLLM, a widely used open-source AI gateway, and roughly 4 terabytes of internal data were stolen — including contractor Social Security numbers, W-9s, passport and government-ID scans, and recorded AI video interviews. Mercor confirmed the breach on March 31, 2026. ClaimsHero, an Arizona law firm working with partner attorneys, is filing individual arbitration claims before JAMS (required by Mercor's Worker Agreement) on behalf of affected contractors, with estimated damages up to $5,000+ per claim. There is no upfront cost — the firm works on contingency and is paid only if your claim succeeds. You may qualify even if you never received a breach notification.\nAttorney advertising intake: this is not a settled class action. Payout is not a law firm and does not provide legal advice. Submitting information does not guarantee eligibility, attorney representation, an attorney-client relationship, or any recovery; those outcomes depend on law-firm review, applicable law, and a separate agreement with counsel.\nSponsored listing.
