San Diego Comic-Con 2026: Dates, Marvel Panel & LEGO News

One of the Events of the Year Is Back

San Diego Comic-Con 2026 opens with Preview Night on Wednesday, July 22, and runs through Sunday, July 26 at the San Diego Convention Center. If you grew up collecting the trailers, the panel-floor leaks, and the con-exclusive figures the week after everyone else, you know exactly why this is circled on our calendar every year — it’s less a trade show than the one week where every fandom we cover shows up in the same building at once.

To be clear about what this piece is: nothing here is a leaked panel breakdown or a “here’s what’s definitely happening” claim. Hall H hasn’t happened yet as we publish this. This is the hype piece — the dates that are actually locked in, and an honest rundown of what we’re personally hoping to see once the doors open.

LEGO Marvel Spider-Man vs. Mysterio: The Daily Bugle (76342) (opens in a new tab)

Our current favorite Marvel display build while we wait to see the SDCC Helicarrier up close — 781 pieces, seven minifigures, a poseable Rhino mech.

Marvel’s Back in Hall H — and We’re Cautiously Thrilled

Marvel Studios skipped Hall H last year, which made the confirmation that they’re returning this Saturday feel like a bigger deal than it might in a normal year. The panel is officially billed as “special guests from across the Marvel Cinematic Universe” sharing “an exclusive look at what’s next” — vague on purpose, but every outlet covering it points at the same expectation: a deeper look at Avengers: Doomsday, which already broke trailer-view records twice over this month.

Here’s the honest, unconfirmed wishlist, clearly labeled as a wishlist: an update on Secret Wars, any real footage from the X-Men reboot, and something concrete on Black Panther III. None of that is promised. But after a trailer that put the original Fox X-Men cast in the same frame as Robert Downey Jr.’s Doctor Doom, Hall H is the first place any of it would actually get confirmed on stage instead of teased in a trailer. If your household has been working through the MCU Watch Order to get ready for December, this weekend is good motivation to keep going.

The LEGO Booth Is the Real-World Draw

This is the part of Comic-Con that actually matters for shelf space, not just screen time: LEGO’s booth (#2829, planted right between Star Wars and Marvel) is putting a S.H.I.E.L.D. Helicarrier on the show floor, alongside new Marvel sets. Helicarrier drops are exactly the kind of thing that turns into a genuine collector event — floor exclusives at LEGO’s SDCC booth have a track record of selling out fast, so if you’re the kind of parent who’s already eyeing display space next to a set like the Daily Bugle (76342), this is worth watching closely once the show floor opens.

LEGO is also running a panel celebrating 15 years of LEGO NINJAGO — a genuinely nice reminder for anyone whose kids (or anyone who was a kid themselves) grew up with Kai and Lloyd, and a sign LEGO is treating this Comic-Con as more than a Star Wars/Marvel showcase.

Catch up on the MCU before Hall H — the Doomsday trailer rewards knowing your Endgame from your Secret Invasion.

What Else We’re Watching

We don’t have confirmed gaming-beat news to report yet — no reveals, no dates — and we’re not going to invent any just to fill out this preview. What we will do is what we do every week on our daily beats: if a real trailer, set, or game reveal drops out of San Diego this weekend, it gets its own LEGO, gaming, or movies & TV brief the day it happens, not a bundled recap after the fact. That’s the actual advantage of publishing this preview today — we’re set up to jump on the real stuff the moment it’s confirmed, instead of writing the recap a week late like half the internet.

Start a free Prime Video trial and get the MCU rewatch going before Hall H on Saturday.
