A wave of excitement has swept through the Harry Potter fandom following a recent social media post. On March 24, 2026, Instagram user Asha Soetan shared a post that read: "Who’s ready for the first Harry Potter trailer- cause it’s about to drop! ". The post also tagged official HBO accounts and the main Harry Potter handle, along with various show-related hashtags.

It's important to remember this is an individual's post and not an official announcement from HBO or Warner Bros. However, it certainly gets us thinking about when we might finally see our first glimpse of the much-anticipated series. We know that filming for the first season is well underway, having commenced in the summer of 2025 and projected to conclude by mid-2026. With the HBO Original series officially slated for an early 2027 release, a trailer dropping sometime this year would make perfect sense. It would build momentum and give us a taste of what Francesca Gardiner, Mark Mylod, and the rest of the incredible team have been working on.
