Google's Gemini is experiencing explosive growth, with monthly active users jumping 30% to 346 million between August and November, while ChatGPT's growth slowed to just 5%. The surge in mobile app downloads and website visits has triggered an internal 'code red' at OpenAI, as Sam Altman refocuses efforts on improving ChatGPT's core experience. Meanwhile, European regulators have opened an antitrust investigation into Google's AI practices.

Gemini User Growth Accelerates at Six Times ChatGPT's Pace

The AI chatbot race has entered a critical new phase as Google's Gemini demonstrates remarkable momentum against market leader ChatGPT. According to data from Sensor Tower reported by The Information, Gemini's monthly active users surged approximately 30% to reach 346 million between August and November, compared to ChatGPT's modest 5% increase to 810 million users

Google's Distribution Advantage Extends Beyond Standalone Apps

While ChatGPT maintains its position as the most widely used chatbot with nearly 900 million weekly active users, Google's competitive edge extends far beyond direct app-to-app comparisons

2

. ChatGPT operates as an isolated system available primarily through its website and app, whereas Gemini has embedded itself throughout Google's ecosystem, including Gmail, Google Drive, and Google Worksuite

.

Google CEO Sundar Pichai revealed in July that more than 2 billion people see AI Overviews every month, and the Gemini app alone has over 650 million monthly users

. Google Search's AI Mode has attracted over 75 million daily active users globally

. Sensor Tower estimates that twice as many U.S. Android users access Gemini through the operating system itself rather than the standalone app, a built-in distribution channel that ChatGPT lacks despite its integration into Apple's iOS

OpenAI Code Red Signals Urgency as Competition Intensifies

The rapid shift in gaining market share has prompted Sam Altman, CEO of OpenAI, to declare an internal code red last week

. This designation marks a period where OpenAI has committed to putting all side projects aside to focus exclusively on improving the core ChatGPT experience and making it smart enough to compete with Gemini 3

Rumors of GPT-5.2 are circulating, with expectations that this minor yet important update will be announced in the coming days. The update aims to match the performance of its competitors, particularly as Google's Gemini 3 Pro model has demonstrated superior performance over ChatGPT 5 Pro across multiple benchmark tests

. On Humanity's Last Exam, a 2,500-question assessment spanning math, science, logic and history, Gemini 3 Pro achieved 37.5% accuracy versus ChatGPT's 26.5%

User Engagement Metrics Reveal Shifting Patterns

User engagement data shows evolving patterns in how people interact with these AI platforms. Gemini users now spend around 11 minutes per day in the app across six sessions, more than double the time logged in March, representing a 120% increase

. ChatGPT users still spend more time overall, averaging approximately 17 minutes daily across eight daily sessions last month, up 6% from March

Antitrust Scrutiny Mounts as Market Dominance Questions Emerge

As Gemini rapidly expands its footprint, regulators are questioning whether its advantage stems from technological innovation or from market power. On December 9, the European Commission opened a formal antitrust investigation into whether Google's AI Overviews and AI Mode misuse publisher content without compensation, thereby bolstering the company's market dominance

2

. The inquiry follows a July complaint from the Independent Publishers Alliance, which argues Google's AI summaries siphon revenue from news outlets

2

.

Authorities are examining whether Google unfairly diverts traffic away from publishers and limits competitors' access to comparable data. The EU probe fits into a broader pattern of antitrust scrutiny under the Digital Markets Act, including earlier penalties tied to Android and Google's advertising practices

2

. For the broader AI industry, these developments signal that rapid growth in the AI chatbot race will likely attract increased regulatory attention, particularly when companies leverage existing platform advantages to accelerate adoption.
