ChatGPT's soaring popularity may have made the AI program the fastest growing app of all time.

ChatGPT is set to exceed the growth TikTok saw when it first launched, according to analysts at investment firm UBS, Reuters reports. “ChatGPT had 57M MAUs (monthly active daily users) in December and January shows no slowdown,” UBS says in a report it shared with PCMag. 

“Data on [daily active users] suggests the site will surpass 100M MAUs in January, a massive achievement in such a short period of time. In 20 years following the internet space, we cannot recall a faster ramp in a consumer internet app,” the report adds.

For perspective, it took TikTok about 9 months after its global launch to add 100 million users and Instagram 2.5 years to do the same, according to UBS. The report adds that ChatGPT saw about 13 million unique visitors per day in January, double the amount from December, according to the investment firm’s estimates. 

The growth is good news for Microsoft. Last month, the tech giant announced plans to pour billions more into ChatGPT’s creator OpenAI to commercialize the AI technologies. So expect more powerful versions of ChatGPT to arrive for the Bing search engine and Microsoft Office.

The rise of ChatGPT, which is free, also puts pressure on Google’s search engine. ChatGPT has shown it's adept at answering questions on a variety of topics, although the accuracy can vary. In addition, it can write essays, fix computer code, and spruce up resumes, cover letters, and marketing pitches. As a result, the program is sparking questions over whether ChatGPT and future AI programs will not only replace Google, but also supplant white-collar work. 

UBS expects Google to respond by prioritizing its own AI programs, but the effort won’t be without risks. “Google is in a catch-22, where it either (1) fails to impress, feeding questions around competitive position or (2) it overcommits, causing concern around (i) monetization risk and (ii) margin erosion,” the report says. 

In the meantime, the surge in growth for ChatGPT has been making it harder for free users to access the program. During times of high traffic, OpenAI will be forced to cut off access. In response, the company is rolling out a paid version called ChatGPT Plus, which can offer uninterrupted access, for $20 per month.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
