TikTok expands #BookTok bestseller list as book sales surge across Europe

TikTok has turned #BookTok into more than a marketing funnel. With an inaugural top 20 made up entirely of female authors and Chloe Walsh appearing more often than any other writer, the platform’s new bestseller list underscored how quickly TikTok has become an unofficial gatekeeper for what sells in publishing.

The expansion comes with hard numbers behind it. TikTok said more than 50 million books recommended by #BookTok were sold across Europe in 2025, generating €800 million in revenue across key markets. Germany was the center of that momentum, accounting for 28 million of those sales and €482 million in revenue. TikTok said the rollout of the list, announced March 19, 2026, was expanding beyond Germany into the United Kingdom, Italy and Spain after first launching in Germany in 2023 and then Austria and Switzerland in 2024.

TikTok said the monthly list is meant to highlight the most successful titles inside the #BookTok community and, in the new markets, will be based on platform insights alongside sales data from Media Control and NielsenIQ BookData. That formula reflects the platform’s broader influence on discovery: TikTok said more than a third of 16- to 39-year-olds in Germany discover new books on #BookTok, and around two-thirds of that age group say creators influence their purchases at least to some extent.

The broader ecosystem around the hashtag has grown fast enough to change the business calculus for publishers. TikTok said there were nearly 53 million #BookTok posts on the platform in 2025, and that approximately 59 million print book sales in 2024 could be tied to BookTok-related creators or content. In Germany, TikTok and Media Control said more than 12 million #BookTok books were sold in 2023, up 56% from the year before, a signal that the market was already scaling before the list widened further.

The titles most associated with that surge fit a familiar pattern. The Housemaid, Fourth Wing and Heated Rivalry reflect the kind of backlist and genre fiction that BookTok has repeatedly lifted into the mainstream, especially romance, fantasy, young adult fiction and books by women authors. Chloe Walsh’s repeated presence on the new list showed how a single creator-driven ecosystem can amplify an author’s entire catalog rather than just one breakout hit.

TikTok has also begun tying BookTok to a larger entertainment strategy. At Berlinale 2026, the company said at least 15 of the top 20 cinema films in Europe last year were viral sensations on TikTok, and it launched a #BookToScreen BookTok Bestseller List to spotlight titles moving from page to screen. The message is clear: in publishing and beyond, TikTok is no longer just surfacing trends. It is helping decide which stories become commercial events.
