Nearly one in five American jobs sits in the blast radius of AI automation, according to a new framework from OpenAI. The company's analysis estimates that 18% of US occupations face high short-term automation risk, with another 24% likely to see employment declines as AI reshapes task composition.

Only 46% of jobs are expected to see limited change. The framework, covering 921 occupations representing 99.7% of US employment, is among the most comprehensive attempts to forecast AI-driven labor disruption.

The report identifies a significant 'capability overhang'-AI tools can already perform many tasks across hundreds of roles, but adoption lags. ChatGPT usage is roughly three times higher in jobs deemed most vulnerable, suggesting those tasks are prime candidates for full automation.

Key constraints currently insulating certain jobs include regulatory requirements, relational necessity, and physical presence. Healthcare, education, and law are cited as sectors where human oversight remains essential.

Separate research from Tufts University's AI Jobs Risk Index estimates 9.3 million US jobs are at high risk, with potential income loss between $200 billion and $1.5 trillion-the upper end roughly equal to Spain's entire GDP.
