Comment:

 As documented on MDN, `speculationrules` is a
 [https://developer.mozilla.org/en-
 US/docs/Web/HTML/Reference/Elements/script/type/speculationrules valid
 value for the type attribute] for the Speculation Rules API. You can read
 more about WordPress's use of [https://make.wordpress.org/core/2025/03/06
 /speculative-loading-in-6-8/ speculative loading in the dev-note].

 While the W3C's validator is a helpful too, it can be a little behind
 browser implementations as features gain support during the late stages of
 the standardization process. WordPress focuses on what will be useful for
 users and will often implement such features as they arrive in browsers.
 This is one such case.

 If you wish to remove the speculative loading API from your site, you can
 use the `wp_speculation_rules_configuration` hook to do so.


 {{{
 add_filter( 'wp_speculation_rules_configuration', '__return_null' );
 }}}


 I'm going to close this ticket off as wontfix, as I expect the validator
 will recognise the speculation rules API in a future update.
