iOS 26 public beta could drop as soon as tomorrow, based on leaked build numbers

Bloomberg’s Mark Gurman has previously indicated that the iOS 26 public beta was likely to drop on around July 23 – and there may now be additional support for that date.

A leaker with a solid track record has shared information suggesting that developer beta 4 will be available sometime today, which would potentially allow the public beta to land tomorrow …

Apple has said only that the public betas for iOS 26, iPadOS 26, macOS 26, watchOS 26, and tvOS 26 will be available sometime in July. We’re already later in the month than usual, and there’s not a lot of July left now!

Gurman said a week ago that he was expecting the public beta “around the 23rd,” which is of course now tomorrow. We’d expect a developer beta 4 before then, which would mean that would have to drop sometime today.

MacRumors cites a private X account yesterday sharing claimed build numbers for the 4th developer betas.

iOS 26 and iPadOS 26 beta 4 (23A5297i)
macOS 26 beta 4 (25A5316i)
tvOS 26 and HomePod Software 26 beta 4 (23J5316g)
watchOS 26 beta 4 (23R5317g)
visionOS 26 beta 4 (23M5300g)

The site notes that the leaker has a solid track record of leaking these the day before they drop.

The public betas landing just a day after the final developer betas would be tight, but not impossible if there are very few changes from developer beta 3.
