Fetches, at low priority, something the next navigation will probably want.
Where preload serves the current page, prefetch bets on the next one: it downloads the resource at minimal priority, in idle moments, and keeps it for the navigation that probably follows — part 2 of the article, the most-clicked search result.
It is a hint, not an order: the browser may ignore it when the network is busy or the user asked to save data. And the partitioned cache of modern browsers limits its reach across sites — for speculating whole pages, the successor is <script type="speculationrules">.
