Steam AI disclosures reach 49.9% of new releases in October 2026

Of Steam games released in October 2026, 49.9% disclosed AI-generated content. That share was 26.4% in October 2025. It was 1.7% when Valve's mandatory disclosure began in January 2024. Disclosure concentrates among small, high-volume releases. For publishers, the label now tracks a production model more than a fringe practice.

Disclosure has become the default for new releases
Reddit user ploz analyzed about 63,600 Steam games released since January 2024.
The annual disclosure share was 13.2% in 2024.
It rose to 24% in 2025.
It reached 40.1% in 2026 year to date.
These are community figures from public Steam data, and Valve did not publish them.

AI assets cluster in low-visibility, high-volume catalogs
Of 2026 games with fewer than 10 reviews, 47% disclosed AI use.
Of games with 1,000+ reviews, 14% disclosed AI use.
Developers with 10+ releases in 2026 disclosed AI in 68% of games.
Single-release developers disclosed AI in 37% of games.
Review counts are not a direct measure of sales.

Generative AI is replacing commodity asset work
Artwork appeared in 63% of disclosures.
Text and translations appeared in 30%.
Store page and marketing materials appeared in 26%.
Music appeared in 21%.
Code appeared in 16%, voices in 7% and runtime generation in 3%.
These categories map to work that studios traditionally outsource, such as art, localisation and store creative.

Compliance rules shape what the data can show
In January 2026, Valve narrowed disclosure to content players see or hear.
Behind-the-scenes efficiency tools fall outside the requirement.
Games that generate content during play need additional safeguards.
Disclosure is self-reported, so undisclosed AI use is missing from the figures.
Some flagged games lacked readable statements, so the usage breakdown covers a smaller set.

Reception and storefront signals point to commercial risk
Among games with 50+ reviews, AI-disclosing titles averaged 77% positive reviews.
Titles without disclosure averaged 83% positive reviews.
The data does not show that AI caused this gap.
Steam offers no filter to exclude AI-generated games.
Itch.io has added an AI filter and removes low-quality AI games.
Valve said it is aware of player complaints but has given no timetable for a fix.
What this means
For Publishers & Developers: Budget human-made art and store creative for flagship titles where a disclosure label could weigh on reviews.
For Investors & VC: Add AI-disclosure status and asset provenance checks to diligence on Steam-first studios.
For Service Vendors: Redirect art and localisation outreach toward mid-size and premium studios that are keeping their releases disclosure-free.
