Last updated: June 26, 2026
Our research team conducted a comparative study on the U.S. and global market penetration of the two dominant online search platforms, Google and ChatGPT. Using a blend of client analytics, third-party usage datasets, and anonymized user behavior logs, we developed a model to estimate monthly active users (MAUs), engagement time, and share of total digital query volume.
While Google remains the longstanding leader in information retrieval, the meteoric rise of ChatGPT has introduced new use cases for search, particularly around long-form conversational queries and creative tasks. However, the AI chatbot landscape itself is shifting rapidly. ChatGPT reached 1 billion monthly active users in May 2026, becoming the fastest app in history to reach that milestone. At the same time, Google Gemini has scaled rapidly, and rivals including Anthropic’s Claude and Meta AI have posted triple-digit year-over-year growth rates, signaling a far more competitive landscape ahead.
This report provides a side-by-side quantitative analysis of the two platforms, beginning with a high-level market share comparison. In the sections below, we further segment usage by device type, demographic groups, and user intent.
Google vs ChatGPT Market Share
In the table below, we break down the total estimated digital query market share held by Google and ChatGPT as of Q2 2026.
Google vs ChatGPT Market Share — Q2 2026
| Platform | Monthly Active Users (Global) | Share of Total Digital Queries | Avg. Session Duration |
| Google Search | 5.3 billion | 77.0% | 6m 12s |
| ChatGPT | 1 billion | 17.9% | 13m 09s |
| Other (e.g., Bing, Perplexity) | 610 million | 5.1% | 4m 33s |
Key Insights:
- Google still dominates the LLM sector, with approximately 77% of global digital queries.
- ChatGPT reached 1 billion monthly active users in May 2026. It commands approximately 17.9% of total digital queries and poses the greatest threat to Google’s market dominance in the past 20+ years.
- Google Gemini has scaled rapidly to 750 million monthly active users, driven by native integration across Google Search, Android, and Workspace, positioning it as ChatGPT’s most significant long-term competitor.
- Despite having fewer total users than Google, ChatGPT has a substantially longer session duration, indicating deep user engagement.
Google vs ChatGPT Market Share Over Time
In the following graph, you can see the trend lines for Google and ChatGPT’s market share.
Google vs ChatGPT Market Share, Q1 2023 — Q2 2026
However, when you break out the data by transactional searches only, which are by far the most valuable to businesses, Google is less vulnerable to ChatGPT.
Google vs ChatGPT Market Share, Transactional Queries Only
Q1 2023 — Q2 2026
Market Share by Device Type
In the table below, we compare usage of Google and ChatGPT across mobile and desktop platforms, revealing device-based user behavior trends.
Google vs ChatGPT Market Share by Device Type — 2026
| Platform | Desktop Usage Share | Mobile Usage Share |
| Google Search | 37% | 63% |
| ChatGPT | 62% | 38% |
Research Notes:
- ChatGPT sees stronger engagement on desktops, suggesting preference among professionals and researchers.
- Google’s mobile-first design solidifies its dominance among casual and on-the-go users.
Market Share by Age Group
In the table below, we detail market share trends segmented by user age group.
Google vs ChatGPT Market Share by Age Group — 2026
| Age Group | Google Share | ChatGPT Share |
| 13–24 | 74% | 17% |
| 25–44 | 80% | 13% |
| 45–64 | 86% | 8% |
| 65+ | 89% | 5% |
Key Insights:
- Younger demographics are more likely to use ChatGPT, particularly in academic and creative tasks.
- Google’s dominance increases with age, aligning with traditional search behavior norms.
Market Share by User Intent
In the table below, we classify digital queries into primary intent categories, showing how Google and ChatGPT are used differently.
Google vs ChatGPT Market Share by User Intent — 2026
| Intent Category | Google Share | ChatGPT Share |
| Navigational | 93% | 3% |
| Informational | 71% | 23% |
| Transactional | 90% | 5% |
| Generative/Creative | 29% | 64% |
Key Insights:
- Google leads in transactional intents due to (a) rich ecommerce and map results on the B2C side; and (b) greater trust for the format of browsing multiple viewpoints/websites vs the “single source of truth” ChatGPT format in higher-stakes purchasing scenarios.
- ChatGPT dominates in generative/creative queries such as ideation, storytelling, and academic drafting.
AI Chatbot Competitive Landscape
While Google Search and ChatGPT occupy different market categories, significant competitive shifts are occurring within the AI chatbot market that have direct implications for ChatGPT’s long-term trajectory. The data below is scoped specifically to AI chatbot web traffic share, a different metric from the total digital query share in the tables above.
AI Chatbot Web Traffic Market Share — Q2 2025 vs. Q2 2026
| Platform | Q2 2025 | Q2 2026 | YoY Change |
| ChatGPT | ~86.7% | ~61.8% | ▼ 24.9 pts |
| Google Gemini | ~5.7% | ~13.1% | ▲ 7.4 pts |
Key Insights:
- ChatGPT leads but is losing ground fast. ChatGPT’s 24.9 percentage point year-over-year decline is a significant loss for any platform at its scale. OpenAI reported in February 2026 that ChatGPT has more than six times the monthly web visits of the next largest AI platform.
- Gemini is the biggest winner in YoY growth of chatbot web traffic, having more than doubled its share from 5.7% to 13.1%. By early 2026, Gemini had reached 750 million monthly active users, making the gap between the two platforms narrower than web traffic share alone suggests.
- The gap between available options has narrowed significantly, from approximately 81 percentage points in Q2 2025 to 48.7 points in Q2 2026. If current trajectories hold, Gemini could challenge ChatGPT’s dominance within the next 12 to 24 months.
- Beyond Gemini, Claude (Anthropic) and Meta AI are the fastest-growing AI platforms, posting year-over-year MAU growth of 640% and 973%, respectively. While both start from a smaller base than ChatGPT or Gemini, their growth rates signal a rapidly broadening competitive landscape.
