Pet Simulator 99 Update 99 is scheduled for October 24, 2026, according to the game's Roblox experience listing, but players should separate the scheduled update from claims about early access. As of this article's research check, BIG Games' latest detailed developer post available on its official blog describes Update 98, “Diamond Mountain,” published October 17. We could not independently verify specific Update 99 tester leaks, unreleased pet names, reward odds, or early-access screenshots from an official source.

Quick answer: Is Pet Simulator 99 Update 99 confirmed?
The Roblox listing displays an Update 99 event for October 24, 2026. That supports the scheduled date, but it does not by itself confirm every detail circulating in community posts. The safest approach is to check the in-game update, the official BIG Games developer blog, and announcements from the game's verified channels before relying on a claimed leak.

What we can verify before Update 99
The latest detailed developer post we found is Update 98, “Diamond Mountain.” BIG Games described a mountain progression event with rubble walls, diamond rewards, a Yeti battle, trails, expeditions, a Season Pass, and new pets. Those are confirmed details for Update 98—not proof that the same mechanics, pets, or rewards will carry into Update 99.
Five things players should check when Update 99 goes live
1. Confirm the update inside the game
Join the official Roblox experience and look for the live update banner, new area, event interface, or patch notes. A countdown or scheduled event listing is useful, but the in-game release is a stronger way to confirm what actually shipped.
2. Check whether the new content is available to everyone
Community posts sometimes describe a test server, developer preview, private server, or staged rollout as “early access.” Those are not interchangeable. Look for a clear source and timestamp before treating a screenshot as evidence that every player can access the content.
3. Verify new pets and reward odds
Do not trust a pet name, rarity, hatch chance, or leaderboard reward solely because it appears in a repost. Compare it with official patch notes and, where possible, the live in-game interface. If odds are not published, report them as unknown rather than guessing.
4. Check whether older event rewards have changed
When a new update arrives, players often want to know whether a previous event remains active, whether items are still obtainable, and whether trading values have moved. Confirm each item in-game before spending diamonds or trading valuable pets. A screenshot alone may be old or taken from a different server state.
5. Treat “tester leaks” as unverified until sourced
A credible report should identify where the footage came from, when it was captured, and whether the creator has permission to share it. Cropped clips, reposted screenshots, and claims without an original source can be misleading. We did not find a reliable official confirmation for specific Update 99 early-access features during this check.

FAQ
When is Pet Simulator 99 Update 99?
The Roblox experience listing shows an Update 99 event for October 24, 2026. Check the live game and official announcements for the actual rollout time in your region.
Are Update 99 early-access leaks confirmed?
We could not verify specific tester leaks through the official sources checked for this article. Treat individual screenshots, pet names, and reward claims as unconfirmed until a reliable source or the live game supports them.
Will Update 99 add new pets?
That detail should be confirmed from the official Update 99 notes or the live game. The previous update introduced multiple pets, but that does not establish the contents of the next update.
Where can I read the official patch notes?
Use the BIG Games developer blog and the official Roblox game page. This article will need an update if new official details become available.
Bottom line
Update 99 is listed for October 24, 2026, but a scheduled update is not the same as a verified early-access leak. Until official notes or live gameplay confirm the specifics, players should avoid treating unverified pet names, reward odds, and tester screenshots as fact. We will distinguish confirmed details from speculation as better evidence becomes available.
