Evidence suggests that Jason’s directional prediction—that the official mobile app would drive about an order‑of‑magnitude jump in both users and usage—has essentially come true, even if the user count has not landed exactly at 10×.

Baseline (pre‑app):

• By January 2023, before any official mobile app, ChatGPT had already surpassed 100 million monthly active users, widely reported as the fastest growth for a consumer app at the time. (en.wikipedia.org)
• Web traffic was about 616 million visits in January 2023 and climbed to around 1.8 billion monthly visits by April–May 2023, just before and around the iOS app launch. (nerdynav.com)

Post‑app user growth:

• OpenAI CEO Sam Altman announced 100 million weekly active users in November 2023. (techcrunch.com)
• Weekly active users then grew to 300 million by December 2024 and 400 million by February 2025. (theverge.com)
• By DevDay 2025, Altman reported around 800 million weekly active users, with Business Insider and other outlets repeating that figure. (businessinsider.com) Relative to the ~100M active‑user baseline in early 2023, that’s roughly a 7–8× increase in recurring users.

Post‑app usage (volume) growth:

• Within a week of its late‑2022 launch, ChatGPT was handling on the order of 10 million queries per day. (digitalinformationworld.com)
• By December 2024, OpenAI said ChatGPT was already processing over 1 billion messages per day, a ≥100× jump versus those early levels. (theverge.com)
• In July 2025, OpenAI disclosed that ChatGPT now handles about 2.5 billion prompts every day, a 150% increase over late‑2024 usage. (timesofindia.indiatimes.com) That is clearly well over a 10× increase in usage volume compared with the pre‑app era.

Role of the mobile app:

• The official iOS app launched in the US on May 18, 2023, and expanded to dozens of countries and then 152+ countries by early June; Android followed in August 2023. (iqiglobal.com)
• Since then, the app has become a central access point: by mid‑2025 it had hundreds of millions of monthly active mobile users and, in 2025 alone, an estimated 300M+–400M+ additional downloads, with total installs approaching 700M. (statista.com) This mobile reach plausibly underpins much of the jump in both user count and query volume.

Putting this together:

• User count has increased by around 7–8× versus the pre‑app 100M‑user baseline—not literally 10×, but close to the “roughly an order of magnitude” framing.
• Usage volume has jumped far beyond 10×, from millions of daily queries in early 2023 to billions per day by mid‑2025.

Given that his claim was qualitative (“game over… going to 10x the number of users and 10x the amount of usage”), and that both users and especially usage did, in fact, grow on roughly that scale after the official app rollout and broad availability, the fairest assessment is that the prediction was basically right in substance, even if the current user count falls somewhat short of an exact 10×.
