The numbers, ready to quote
Workday runs hiring at 38.6% of the 713 large employers verified against their live careers portals in June 2026 (275 of 713) — the most-used ATS, but far from a majority.
The top three ATS vendors — Workday, Greenhouse, and SAP SuccessFactors — cover 60.0% of verified large employers (428 of 713). The other ~40% is a long tail no "triopoly" claim accounts for.
Greenhouse is the ATS at 13.3% of verified large employers (95 of 713), concentrated in venture-backed tech.
SAP SuccessFactors runs hiring at 8.1% of verified large employers (58 of 713) — an enterprise vendor routinely missing from ATS market-share claims.
Oracle Cloud HCM is the ATS at 6.3% of verified large employers (45 of 713).
iCIMS is the ATS at 6.3% of verified large employers (45 of 713).
Taleo is the ATS at 5.5% of verified large employers (39 of 713).
Eightfold is the ATS at 3.5% of verified large employers (25 of 713).
30 distinct ATS platforms appear across the 713 verified employers — the market is far more fragmented than the two- or three-vendor story usually told.
29 verified large employers use no third-party ATS at all — Amazon, Meta, Google, and Microsoft all run proprietary internal systems.
The State of ATS 2026 dataset covers 743 large employers; 713 (96%) were verified by inspecting the apply-URL host of their live careers portal in June 2026.
