Supposedly the latest trend deciding what novels get accepted by literary agents isn't the total number of words in the book, it's the total number of words in each chapter. They're getting much more strict about wanting chapters that are 1250-1500 words.
The reason is audiobooks: Having shorter chapters is a better user experience and audiobooks are really hot (money makers) right now.
This is just an anecdote though. I'm not an expert (only wrote one novel and my chapters were like ~2,500-3,500 words).
