LEGO 40866 Santa's Holiday Sleigh Adventure has now appeared on the official LEGO coming-soon page, giving this upcoming Other release an official LEGO.com listing in the US. The page currently confirms a price of $29.99, an age recommendation of 9+, and a total of 187 pieces. LEGO also lists the set as Coming soon on October 1, 2026, which is the safest official release wording to rely on right now. That matters because this is no longer based on retailer leaks or catalogue speculation: the set is now visible through LEGO’s own storefront with official images and core product facts. For builders tracking the next wave of announcements, that is enough to treat Santa's Holiday Sleigh Adventure as a properly revealed new set and to start looking at where it fits in the wider 2026 line-up.
LEGO has added Santa's Holiday Sleigh Adventure to the official LEGO coming-soon page, with the full listing also live on the official LEGO product page. That gives us a clean official basis for a new-set story, because the essential facts are visible on LEGO’s own platform rather than needing to be pieced together from third-party sources.

- Set number: 40866
- Theme: Other
- Age rating: 9+
- Piece count: 187
- US price: $29.99
- Availability: Coming soon on October 1, 2026

What stands out about LEGO 40866 Santa's Holiday Sleigh Adventure
The theme placement is one of the first useful clues here. As an officially listed Other set, this release now has a confirmed place in LEGO’s current planning, which is important for anyone tracking how the theme is expanding through the second half of 2026.
The official LEGO listing does not require guesswork on the basics, but it still leaves room for fans to read into positioning. A set with 187 pieces at $29.99 will naturally be judged a little differently from a huge flagship build, and the age mark of 9+ also helps clarify the intended audience.
Release date and availability
LEGO currently shows the set as Coming soon on October 1, 2026 on the US store. If that wording includes a specific date, the current launch point appears to be October 1, 2026. If LEGO adjusts the timing later, the official product page will be the most reliable place to watch for that change.
For now, the important thing is simple: LEGO 40866 Santa's Holiday Sleigh Adventure is officially live on LEGO.com as a coming-soon discovery item. That is enough to move it out of rumor territory and into confirmed new-set coverage.
Bottom line: LEGO 40866 Santa's Holiday Sleigh Adventure is now part of the official US coming-soon line-up, with verified pricing, piece count, age guidance and official LEGO images already in place. For fans following upcoming releases, that makes this a set worth tracking ahead of launch.
