Update, 4/13 — George R.R. Martin's publisher has issued an official statement about this "supposed leak," which you can read here.
Fans have been waiting nearly 15 years for The Winds of Winter, the long overdue penultimate novel in George R.R. Martin's A Song of Ice and Fire. As someone who has been on the ground that entire time, I can say with certainty that over those years, there have been no small number of claims that Martin had finished the book, or that he'd finished that book and the subsequent novel A Dream of Spring and was planning to release them together, etcetera. Fans are desperate for any small ray of hope they can find that Winds will actually come out, and there are no shortage of bad actors on the internet ready to take advantage of that desperation for a viral moment.
Now, we may have another on our hands. A post on 4Chan claiming that The Winds of Winter has been handed in to Martin's publisher, Bantam Spectra, is now making the rounds. According to this supposed leak, Martin finished the book sometime in late 2025 and handed it in right around the turn of the new year. It's now in the production pipeline, aiming for a release sometime in the fall to capitalize on holiday sales.
At least, that's what the leak says. Do we believe it? Not particularly. Do we want to believe it? Oh, yes. But since this thing is breaking containment, we definitely need to address it and the likelihood of whether it's true or not.
The Winds of Winter leak explained
Let's start with the source. This post cropped up on 4Chan on Thursday, and the anonymous person who wrote it claims to be a production assistant at Bantam Spectra, Martin's longtime publisher of A Song of Ice and Fire. They don't identify themselves, because they "actually want to keep [their] f***ing job."
"The manuscript was delivered internally in January 2026. Not a partial. The actual full thing. GRRM apparently finished it sometime in late 2025 and the silence from his blog has been intentional, marketing told him to go dark," the post reads. "We have been in full editorial and layout pipeline since February. The official announcement is embargoed until Comic-Con, but we know hes going to announce it on his blog first because he doesnt give a fuck, with the actual release window being around fall. They want those holiday sales."
In addition, the poster claims the book is very long, "think AFFC and ADWD in one book." They claim it's around 1600 manuscript pages, but stop short of saying the exact wordcount because "that alone would identify the source."
Lastly, they claim that a coordinated marketing campaign is being planned with HBO, because obviously the studio would want to capitalize on the release of this book to drum up any extra hype it can for its own Westeros properties.
So that's what the post says. Unfortunately, there are more than a few red flags here that it's likely fake. The first is it appearing on 4Chan at all, which is not exactly a repository for legit information. The second is this "production assistant" having access to this information and posting about it. They claim to have worked at Bantam Spectra for years...but for my two cents, anyone who has worked in publishing that long, who would have access to this sort of information, would more than likely be extremely used to dealing with confidential information on a very regular basis. To risk their career by posting it on a site like 4Chan doesn't square with the experience they're claiming.
There's also the question of the book's length. The leak claims it's "1,600 manucript pages," comparing it to the size of the fourth and fifth books, A Feast for Crows and A Dance with Dragons put together. Those numbers don't add up. According to Martin himself, Dance was 1,510 manuscript pages long, just shorter than A Storm of Swords, which clocked in at 1,540 pages. So a 1,600 manuscript page book wouldn't be like Dance and Feast put together, it would barely be 100 pages longer than A Dance with Dragons.
That is aside from the well-known fact that the whole reason A Dance with Dragons and A Feast for Crows were split into two books is because the length of that story was so massive that it would not have been physically possible to bind it all in one volume without the book falling apart. That remains more or less true, from a production standpoint. This will almost certainly be a hurdle for The Winds of Winter to navigate, but for the leak to just casually claim the book is twice the length of one of the previous volumes without any sort of acknowledgement of how the publisher can navigate the physical limitations of printing a book of that size smells of misinformation.
There's also the question of the Comic-Con announcement date. San Diego Comic-Con takes place from July 23 to July 26 this year, which will likely be right in the thick of House of the Dragon season 3's run. While Martin's publisher could feasibly try to piggyback off that for a release announcement for The Winds of Winter, it's also a very short timeline for the average book marketing campaign. Publication dates are typically announced much farther out; for example, Tor Books announced the release date for Brandon Sanderson's next Cosmere book, The Fires of December, around 10 months before it's due to drop in December. I'm not saying it's impossible that such a massive release as The Winds of Winter could only have three to four months of lead time, but it's unlikely.
There's one other piece of this puzzle that could conclusively prove this leak is false. The poster claims to be a production assistant at Bantam Spectra, the publisher who is widely known to have released Martin's A Song of Ice and Fire books in the United States. However, as of right now, it's not particularly clear whether Bantam Spectra even handles A Song of Ice and Fire anymore. All recent U.S. printings of the books are now being put out by Random House Worlds, a sister imprint of Bantam Spectra's under Penguin Random House that specifically handles large media franchise books. That to me has represented an interesting shift in how Martin's publishers are handling his Westeros works in general — see the A Feast for Crows Illustrated Edition controversy as an example, which was the first of those anniversary editions published by Random House Worlds instead of Bantam Spectra.
Obviously, Martin's contract for The Winds of Winter was originally with Bantam, and I wouldn't be the least bit surprised if they did ultimately produce the book whenever it's released. But right now the evidence seems to point away from them as the current Penguin Random House imprint that deals with A Song of Ice and Fire. This could mean nothing, or it could be a very clear sign that this person posting on 4Chan is faking it.
These are the sorts of details I wouldn't expect a random person on the internet to know. But someone who has worked at a publishing house for years? I would expect them to know these sorts of nuts and bolts for how the sausage is made. And don't get me started on the lack of things like apostrophes and other grammatical issues in the leak. You're a long-time publishing professional and can't string a sentence together correctly? Dubious at best.
All this is to say that for as much as I want to read The Winds of Winter just like the next person, I probably wouldn't put much stock in this particular leak.
The Winds of Winter update — Could we actually see the book in 2026?
So that's what's going on with the leak. It has a lot of fans talking, and it's worth digging through the meat of it see if there's anything of substance — and for my money, there is not. There was another, similar leak back in January that claimed to have a chapter-by-chapter breakdown of The Winds of Winter, with some details that feel doubtful, such as Jaime Lannister becoming a "fire wight," resurrected by Lady Stoneheart to protect her children. There seems to be an uptick in these sorts of deceptive leaks in recent months.
That said, I have already been wondering if we might get some kind of update regarding The Winds of Winter in 2026. The last interview where Martin addressed the book was in late 2025, which was published by The Hollywood Reporter in January. In it, Martin said once more that he had around 1,100 manuscript pages finished for the book (a number he's been saying for quite a while), and that it would "feel like a total failure" if he gave up on the book. "I want to finish," he said.
That interview describes Martin's frustration with not having The Winds of Winter done already, and it doesn't paint a picture of a man who already finished it in secret.
Really, there's no solid reason to think we might get more information about The Winds of Winter this year...but something in my gut says those winds could be shifting. 2026 is shaping up to be a banner year for Westeros. We got the premiere of A Knight of the Seven Kingdoms in January, April is the 15th anniversary of the Game of Thrones television show's premiere, both House of the Dragon season 3 and the stage play Game of Thrones: The Mad King are premiering in June, and the 30th anniversary of the original publication of the first book in the series, A Game of Thrones, is this August. It's not a stretch to say that this is probably the most important year for Westeros since 2011, when Game of Thrones premiered and Martin published A Dance with Dragons. There are few things that could make it better, save some sort of substantial update about The Winds of Winter, which Martin has been toiling away at for 15 long years.
While this new "leak" probably isn't legitimate, I'd be lying if I said I didn't feel a strange sense of hope that we may hear more about The Winds of Winter sooner rather than later. And if not, we'll at least have plenty of other Westeros projects to keep us busy.
