I think Game of Thrones is the next closest to that. Occasionally you'll hear it mentioned along the other IPs mentioned in the title. I think the only thing stopping it is that the Author has stopped publishing books in that series.

Other books that their fandoms absolutely love are Wheel of Time, Mistborn, Stormlight Archive, and Name of the Wind.

NoTw seems to have the same issues as Got for the author not finishing the series.

WoT got an adaptation, which seems to have split the fanbase but ended up with decent critic reviews, which is above average as far as adaptations go. Seems it needs another season or 2 to tell if it can get more solid footing.

Mistborn / Stormlight Archive seems to be the most accessible and complete out of the more highly regarded high fantasies. There has been progress towards and adaptation but no solid news yet.

A series I recently discovered was the Morrigan Crow series, which I think is going to end up being one of the all time greats as well. Though the adaptation will be tricky. Right now they're adapting the first book to be a musical, which I personally think may not work out.
