Work at the Frontier: AI’s effect on freelance work

Freelance markets are an early-warning system for labor. Contracts are short and clients rewrite requirements with every posting, so shifts show up there before they register in employment statistics. OpenAI's economic research team paired Upwork posting data with ChatGPT usage patterns to look for those shifts.

The stakes are not niche. Upwork's own research says 38 percent of skilled U.S. knowledge workers freelance, and its prior study estimated freelance knowledge work generated $1.5 trillion in U.S. earnings in 2024.

The finding we keep coming back to is the pattern across 63 work categories. In 43 of them, activities that were relatively common in ChatGPT lost share on Upwork while less common ones gained. In the other 20, the reverse held. That is a real signal of substitution in some kinds of work, and OpenAI deserves credit for stating plainly that ChatGPT use alone does not explain the changes.

The more optimistic half of the story is about bundling. AI-related postings combined tasks that rarely appeared together before, such as AI-generated video, editing and motion graphics in one brief. The task mix in AI-related postings became 45 percent more diverse between early 2023 and late 2025, roughly the equivalent of moving from about 15 equally common tasks to about 21. Those projects carried larger fixed-price budgets and more hours, while posted hourly rates stayed similar.

We read that as good news for freelancers who can integrate, and a warning for those whose work was a single, well-defined deliverable. The generalist who can stitch AI output into a finished product looks more valuable. The specialist doing one task that a chatbot now handles reasonably well is the one whose category is shrinking. That is not a story about the end of freelancing. It is a story about who gets squeezed inside it.

Our caution: this is research by an AI company and a freelance marketplace, two parties who benefit from a narrative that AI grows the pie. The methods are described and the hedges are there, but we would like to see the underlying data opened to independent economists. Larger budgets that partly reflect broader scope are not the same thing as higher pay per hour of skilled work, and the report itself notes hourly rates were similar.

If this pattern scales, the freelance market becomes a place where AI fluency is table stakes and value migrates to scoping, judgment and assembly. That can be healthy. It can also leave a long tail of workers in shrinking categories with no clear path into the growing ones.

This is part of OpenAI's Work at the Frontier series from its economic research team. The analysis compares ChatGPT use from January 2025 to June 2026 against Upwork posting shares, and notes a gap OpenAI calls the capability overhang between how people currently use ChatGPT and what AI can support.
