Seeking ways to "monetize" AI-generated art, some artists have already begun submitting their AI-generated pieces to stock photography websites like Shutterstock. Searches for "AI generated" or "Midjourney" (a popular image synthesis service) produce thousands of results on the site.

In some cases, a portion of the artwork that isn't labeled as "AI generated" also appears to clearly match Midjourney's art style, which seems to be the most popular image synthesis tool on the site at the moment. As of press time, Shutterstock's terms of use do not prohibit the submission of AI-generated artwork. Shutterstock contributors receive a percentage of the licensing fee that varies from 15 to 40 percent of what Shutterstock makes from the content.
