According to Appfigures, xAI's Grok 4 launch on July 9th spurred a significant revenue surge. By July 11th, Grok's iOS gross revenue jumped 325% to $419,000, a substantial increase from the $99,000 earned the day before the release. This growth suggests strong user adoption and monetization following the introduction of the new AI model, despite its controversial reputation for unfiltered responses.
