It's OVER for accountants? Look at these numbers.
Mercor put 12 licensed CPAs, averaging 5.5 years of experience, up against frontier AI on four accounting tasks. The humans averaged 37%. Claude Opus 5 scored 100% across all 20 attempts, finishing each in under 10 minutes. Most human attempts took 30–180 minutes.
Just 18 months ago, the best AI couldn't beat the average accountant on these tasks. Now it beats even the best participant. Mercor wanted to measure how much AI could help accountants. But AI alone scored perfectly, leaving no room for improvement.
