Nonfiction author here. Some potential advantages Amazon may have over other traditional publishers: Massive amount of data and high-powered data science. Can help inform decisions about what to buy, how much of an advance to pay, etc. Large coffers. Can take more risks in what to buy and make competitive bids. Priority of placement. Amazon the retailer gets a cut of every sale. Amazon the publisher gets another. Clearly, it makes sense to prioritize Amazon's own titles against similar titles from other publishers, unless sales of the non-Amazon title are expected to be substantially higher. A couple of disadvantages: Agents are wary. They know that cooperating with Amazon is going to threaten the health of every other publisher. At least in the short term, authors are going to perceive having Amazon as a publisher as having less cachet. It's largely known for its self-publishing arm, and authors aren't going to want their books to be misperceived as having been self-published, where quality is pretty abysmal. Don't expect your book to end up in brick-and-mortar bookstores.
