New details about 20 upcoming LEGO sets reportedly targeting an August 2026 release have surfaced online. The leaked kits span four licensed LEGO themes: Harry Potter, Fortnite, Minecraft, and Bluey.
Of those four lineups, three have already been officially confirmed as receiving new LEGO sets in 2026. The only exception is LEGO Fortnite, which was most recently refreshed in October 2025 with the BrickHeadz-style build 40884 Drift & Raven, but has not been the subject of any forward-looking product announcements.

In spite of LEGO’s radio silence, its Fortnite offerings will supposedly get refreshed next year. That’s according to a new report from well-known leaker Unibricks, who shared set numbers and piece counts of 20 new kits said to be targeting an August 2026 launch. The leaked details cover seven sets from the LEGO Harry Potter line, six new LEGO Minecraft kits, four unannounced LEGO Fortnite products, and three new additions to the Danish toymaker’s modest Bluey offerings, which first debuted in June 2025. While some of the newly leaked set numbers were already mentioned in prior rumors, there has been no word on their piece counts until now. Additionally, several were previously only rumored for a 2026 launch, a time frame that Unibricks has now narrowed down to next August.

*The “Potential Price” column contains Game Rant’s price estimates based on the leaked piece counts and LEGO themes of the listed sets. It is not part of the leak itself.
The seven leaked Wizarding World kits appear to loosely fit the wave of Harry Potter-themed sets LEGO released in mid-2025, in terms of size and variety. Three are below 500 pieces, two are in the 800-piece ballpark, and then there’s a sizable 2,164-piece build, said to be carrying set number 76473. That last product may be another Hogwarts extension, in the vein of the imposing 76454 LEGO Hogwarts Castle: The Main Tower, which launched in June 2025 and has a near-identical piece count of 2,135. Due to 76473 sharing its theme and having a similar piece count, it may also end up having the same sticker price of $259.99.
The leaked LEGO Fortnite sets are evenly split between small and medium builds. One of them, identified by set number 77082, is nearly as large as the biggest Harry Potter kit from this wave of unofficial info, suggesting a comparable price point. At 1,963 pieces, it would rank as the second-largest Fortnite-themed set to date, only behind LEGO’s 77078 Mecha Team Leader, which numbers 2,503 pieces.
On the Minecraft side, the two largest leaked kits are 21597 and 21595, supposedly containing 754 and 710 pieces, respectively. The overall lower piece counts are consistent with this theme’s blocky build style, which has so far allowed designers to do more with fewer pieces. For instance, the largest LEGO Minecraft set currently available for purchase, 21279 The Enderman Tower, has only 867 pieces but is 17.5 inches (45 cm) tall.
