Supergirl is now streaming on HBO Max in the United States, where it landed as an exclusive on Thursday, September 10, 2026. If you would rather watch it on live TV, it also premieres on the HBO linear channel on Saturday, September 12, 2026 at 8:00 p.m. ET / 5:00 p.m. PT.
That is the whole answer: HBO Max is the only subscription streaming home for Milly Alcock’s DC movie, and it is included with every HBO Max plan, which starts at $10.99 a month. Below is the full rundown on price, start times, cast and what the film is actually about.
How to watch Supergirl right now
The film streams exclusively on HBO Max. There is no separate rental or add-on fee on the platform: if you have any HBO Max subscription, Supergirl is included at no extra cost. It arrived just over two months after its June 2026 theatrical run, which is a fast turnaround for a major studio release.
An audio-described version and a version performed in American Sign Language are also available on HBO Max from the same September 10th launch, so accessibility options are in place from day one.
HBO Max price: which plan you need
Every HBO Max tier includes Supergirl, so you can pick whichever plan fits your budget. Here are the current US prices at the time of writing:
| Plan | Monthly | Yearly | Notes |
|---|---|---|---|
| Basic With Ads | $10.99 | $109.99 | Cheapest option; includes the film |
| Standard (ad-free) | $18.49 | $184.99 | Ad-free, two streams, offline downloads |
| Premium (ad-free) | $22.99 | $229.99 | Four streams, 4K UHD |
If you only want to watch this one movie, the Basic With Ads plan at $10.99 is the least expensive way in, and a monthly plan can be canceled after you have watched. For the sharpest picture, the Premium tier is the one that unlocks 4K.
Supergirl start times, at a glance
| How to watch | Date | Time (ET / PT) |
|---|---|---|
| HBO Max (streaming) | Thursday, September 10, 2026 | Available all day |
| HBO linear channel | Saturday, September 12, 2026 | 8:00 p.m. ET / 5:00 p.m. PT |
Because the streaming version is a library title rather than a timed premiere, there is no countdown to beat on HBO Max — it is ready to play whenever you are. The 8:00 p.m. ET start time only applies to the traditional HBO cable channel on the 12th.
What Supergirl is about
This is the second film in the rebooted DC Universe overseen by James Gunn and Peter Safran, following Superman. Directed by Craig Gillespie and written by Ana Nogueira, it adapts the acclaimed comic Supergirl: Woman of Tomorrow by Tom King and Bilquis Evely.
Milly Alcock plays Kara Zor-El, a harder-edged, more world-weary counterpart to her cousin Superman. The story sends her on a revenge-driven journey across the galaxy alongside a young girl named Ruthye, who is hunting the man who killed her father. It is a road-trip space Western more than a traditional cape-and-cowl origin story, and it runs a lean 1 hour and 47 minutes.
Who is in the cast
Alongside Alcock, the cast includes Matthias Schoenaerts, Eve Ridley as Ruthye, David Krumholtz and Emily Beecham. David Corenswet returns as Superman, and Jason Momoa appears as the bounty hunter Lobo, connecting the film to the wider DC Universe slate.
Where it fits in the DC Universe
Supergirl sits in the first phase of the rebooted DCU, labeled Chapter One: Gods and Monsters, arriving after Superman launched the new continuity. Alcock first appeared briefly as Kara in that film before headlining her own movie here, and Momoa’s Lobo is expected to carry over into future projects. For viewers keeping track of the shared universe, this is an essential chapter rather than a stand-alone spin-off — it establishes a version of the character the franchise plans to build on, even if the theatrical run did not go as Warner Bros. hoped.
Is it worth streaming?
The honest picture: Supergirl underperformed in theaters, grossing roughly $126 million worldwide against a production budget north of $170 million, and reviews were mixed. That makes the HBO Max release a genuine second chance — it is exactly the kind of mid-budget blockbuster that tends to find its audience at home, where the low barrier of a subscription replaces the price of a ticket. If you skipped it over the summer, streaming is the low-risk way to see whether Alcock’s take on the character clicks for you.
