Someone in Amazon probably decided that Audible's unit economics could afford to take a 30% cut, while Kindle's could not. I'm not surprised, since you can often buy a Kindle + Audible book for cheaper than buying the Audible book alone. If you look at the Audible book (such as Wool https://www.audible.com/pd/Wool-Audiobook/B0BKR3Y6SP https://www.audible.com/pd/Wool-Audiobook/B0BKR3Y6SP) the price is often higher than if you look at the Kindle book price, and adding the Audible narration (https://www.amazon.com/Wool-Hugh-Howey-ebook/dp/B088SY4GSD https://www.amazon.com/Wool-Hugh-Howey-ebook/dp/B088SY4GSD). In the Wool example, the Audible book is $31.64, but the Kindle book with the audible add-on is $9.48 ($1.99 + $7.49). Even if the Kindle book was selling for "list price", it would still be cheaper at $27.48. So, I'm guessing there's just a lot less margin headroom to eat a 30% cut on Kindle prices, but plenty to eat that on Audible's prices.
