Sims 4 Kits Move Exclusively to In-Game Marketplace Starting March 17

Starting March 17, 2026, the only way to purchase Sims 4 Kits on PC and Mac will be through the in-game Marketplace. The change, confirmed in The Sims 4 Marketplace Official FAQ, marks a hard cutover: "When the Marketplace launches on PC and Mac on March 17, 2026, Kits will become exclusively available in the in-game Marketplace."

The practical concern most players will ask first gets a direct answer in that same FAQ. "Any Kits you already own will remain in your library and ready to play." Nothing disappears from existing libraries; the shift affects new purchases going forward. The Sims Team framed the move in straightforward terms: "Moving Kits into the Marketplace ensures that we can continue releasing new content without hitting technical or storage limitations."

Console players are not on the March 17 timeline. The Kits-to-Marketplace transition on consoles will happen when the Marketplace arrives on each specific platform, with The Sims Team promising platform-specific updates ahead of those rollouts. No console dates have been confirmed yet.

The Marketplace announcement lands alongside a notable update to SimSweep, a third-party Sims 4 custom content diagnostic tool maintained by SYVR under the basezero-projects repository. Version 2.16.0, posted to the SimSweep changelog on March 5, 2026, added CC filters and expanded malware and risk profiling features. For players who rely heavily on downloaded CC and mods, a diagnostic tool update that sharpens its ability to flag risky content is well-timed as the broader ecosystem shifts toward a centralized in-game storefront.

Community reaction is already visible. In a thread on Simscommunity, user mitariki replied to Brianne two days ago with pointed skepticism: "Oooo having plans of buying them once they are 98% owned by a country known for human rights violations? Sweet! That will be possible, yes." The comment reflects a current of anxiety in some parts of the community that extends well beyond the Kits logistics themselves.

With six days until the PC and Mac Marketplace goes live, the clearest next steps are watching The Sims Team's official channels for any console-specific announcements and checking the basezero-projects repository for further notes on what SimSweep's new CC filters and risk profiling actually examine under the hood.
