Roblox says AI is driving an "explosion of content" on its platform. In its third-quarter 2026 shareholder letter, the company claims users have published more than 70,000 games with Build, its "prompt-to-game" creation tool launched in July. The figure comes as Valve admits it is struggling with a growing flow of AI-generated games on Steam.

According to the letter, Build has been used by more than 500,000 people during its alpha in New Zealand, Singapore, Serbia and Thailand. Spread over the five months since launch, that is roughly 14,000 games a month. Roblox notes the tool is not yet fully launched, so only part of its user base has access. On the earnings call, Baszucki said some Build games already carry advertising and generate revenue, and that most Build users had never opened Roblox Studio before.

AI use goes beyond Build. The company says more than 80% of the top 100 games by hours engaged over the past month used AI tools to speed up creation. Daily asset uploads to the Roblox cloud tripled month over month. Time spent with AI tools by the platform's top creators has also tripled since Q2, and daily users of its MCP server have nearly quintupled. In Q3, Break and Steal an Egg and Huss Valley were built almost entirely with AI and entered the top 20 by concurrent players.

The letter also announces two initiatives. Roblox Everywhere would make Roblox games playable outside the platform. Universal Player works the other way: AI would import an existing game into the Roblox cloud and turn it into a multiplayer experience running on any device. Details remain thin, but the aim seems to be making Roblox a platform for developers of all kinds, comparable to Steam or the PlayStation Store. The company says it aims to capture 10% of the global gaming market and an even larger share in the US.

Roblox argues that as content becomes abundant, attention becomes scarce, and that its edge is distribution through social connections: players come to play with friends, and new games can reach them through friend networks and influencers.

Roblox's stance contrasts with Valve's, which is struggling to manage the flood of AI-generated titles on Steam. Roblox treats this growth as an asset, placing speed and volume of creation at the centre of its strategy.
