Everything you've been told about beating the ATS is built on a number that's wrong.
“75% of large companies use Workday” is the most-repeated stat in resume advice. So we stopped repeating it and checked — the live careers portal of 743 large US employers, one at a time.
Workday is the single most-used applicant tracking system in 2026 — but it runs hiring at 38.0% of large employers, not 75%. The famous number was never counted. It was repeated until it sounded true.
Three more things the advice gets wrong
The top three — Workday, Greenhouse, SAP SuccessFactors — cover 60.3% of verified large employers, not the near-total the "triopoly" story implies. About 40% is a long tail no three-vendor claim accounts for.
Taleo is treated online as an ATS giant. In our verified set it's #9 at 2.5% — its Fortune-500 shops have been quietly migrating to Oracle Cloud for years.
When we started, roughly half of what AI-compiled sources "knew" about which company uses which ATS didn't survive a check against the live careers page. That's why we checked all 743 by hand.
36 distinct ATS platforms turned up across the verified set, and 30 employers — Amazon, Meta, Google, Microsoft — use no third-party ATS at all. “Just optimize for Workday” isn't a strategy.
So which ATS does your company actually use?
The average number is useless when you're applying to one specific employer. Look yours up — then make sure your resume clears it.
Why you can trust these numbers
We inspected the apply-URL host of each company's live careers portal in June 2026 — 707 of 743 confirmed that way, the rest left unverified rather than guessed. The full dataset is open and MIT-licensed, so you don't have to take our word for it: check any row yourself. We'd rather publish a verified 38.0% than repeat a rounder-sounding myth.
