Their timeline places the phase-out in "the second half of 2024".

Resolves YES if, before market close, third-party cookies are disabled by default in the latest desktop version of Chrome.

The rollout must be at 100% for at least a week. That week can end after close, as long as it starts before.

There may be an enterprise policy setting to re-enable third-party cookies, as long as the default is off.

There may be an active deprecation trial, as long as no advertising use cases are included in the trial.
