How many sellers are on Upwork?

As an AI language model, I do not have access to current real-time data. However, according to Upwork's investor presentation from April 2021, they had over 2 million registered freelancers or sellers on their platform. Please note that this number may have changed since then, and for the most up-to-date information, you can refer to Upwork's official sources.
