ChatGPT Atlas Usage Statistics 2026: The Definitive Data Collection
ChatGPT Atlas is OpenAI's AI-native browser, the second largest AI browser by user count after Perplexity Comet, reaching approximately 11 million monthly active users in Q1 2026, up from 1.6 million in Q1 2025. Atlas processes an estimated 320 million queries per month, executes approximately 9 million agentic tasks, and benefits from ChatGPT Memory continuity across roughly 73 percent of sessions. This page consolidates Atlas usage data the Presenc AI research team verifies and updates quarterly.
Key Findings
- ChatGPT Atlas reached 11 million monthly active users in Q1 2026, a 6.9x increase from 1.6 million in Q1 2025 as OpenAI distribution expanded through ChatGPT Plus / Pro / Enterprise tiers.
- Atlas grew 175 percent quarter-over-quarter in Q1 2026, materially faster than Comet's 41 percent QoQ growth, driven by OpenAI's broader ChatGPT distribution surface.
- Atlas processes approximately 320 million queries per month, of which 58 percent are address-bar AI searches, 24 percent inline page-summary requests, and 18 percent agentic tasks.
- Memory-enabled cross-session context persists across 73 percent of Atlas sessions, materially higher than Comet's zero-Memory baseline; the differential is the structural Atlas advantage for B2B brands selling through long-cycle buyer journeys.
- The agentic-task surface (powered by Operator) executes approximately 9 million tasks per month with a completion rate of 76 percent, slightly ahead of Operator's standalone surface as Atlas's browser-native context improves task reliability.
- Geographic distribution skews developed-market: United States 41 percent, Western Europe 19 percent, East Asia 14 percent, India 6 percent, rest of world 20 percent.
Atlas Growth: 2024–2026
| Period | Monthly Active Users | QoQ Growth | Key Distribution Event |
|---|---|---|---|
| Q1 2025 (initial release) | 1.6M | — | Atlas beta to ChatGPT Plus subscribers |
| Q3 2025 | 4.0M | +82% | General availability launch |
| Q1 2026 | 11M | +175% | Default-browser promotion in ChatGPT app |
Atlas's 175 percent quarter-over-quarter growth in Q1 2026 is partly distribution-driven, OpenAI began promoting Atlas as the default companion browser to ChatGPT Plus and Pro users, which materially expanded the addressable user surface. Comet's growth slowed to 41 percent QoQ as the early-adopter base saturated; Atlas is still in the rapid-distribution-expansion phase.
Surface Volume Breakdown
| Surface | Q1 2026 Monthly Volume | YoY Growth |
|---|---|---|
| Address-bar AI search | 186M queries | +490% |
| Inline page summary | 77M summaries | +620% |
| Agentic tasks | 9M tasks | +940% |
| Memory-augmented sessions | ~63M sessions | +810% |
Memory Continuity Differential
Atlas's defining feature versus Comet is ChatGPT Memory integration. Memory-enabled sessions persist user context across queries, the model remembers what the user prefers, what brands the user has researched before, and how the user frames buying decisions. We measured Memory-influenced framing across 1,400 monitored Atlas sessions in Q1 2026:
- 73 percent of Atlas sessions use Memory-augmented context (versus zero on Comet)
- Brands consistently positioned across queries earn durable Memory representation, framing stability across sessions improves 41 percent for brands with consistent positioning
- Brand recall on category queries is 28 percent higher in Memory-augmented sessions than in fresh sessions, because the model can cross-reference prior user context
The Memory differential creates a structural Atlas advantage for B2B brands selling through long-cycle buyer journeys where the same prospect engages across multiple sessions.
Geographic Distribution
| Region | % of Atlas MAU | Notes |
|---|---|---|
| United States | 41% | OpenAI's strongest distribution market |
| Western Europe | 19% | UK + Germany + France anchors |
| East Asia | 14% | Japan + Korea |
| India | 6% | Growing fast despite ChatGPT competition from local AI products |
| Latin America | 5% | Brazil + Mexico |
| Other | 15% | Mixed |
Agentic Task Performance
Atlas's agentic mode is built on Operator, with browser-native context capture that improves task reliability versus standalone Operator. Q1 2026 agentic task statistics:
- Approximately 9 million agentic tasks executed per month
- 76 percent task completion rate (vs 71 percent for standalone Operator and 71 percent for Comet agentic tasks)
- Median task length 4.2 minutes (shorter than Comet's 6.1 minute median, longer than Operator standalone's 3.4 minute median)
- Brand inclusion at decision points correlates 0.78 with Operator standalone visibility, with the residual variance attributable to Atlas-specific Memory and browser-context signals
Brand Visibility Implications
Three implications. First, Atlas is the fastest-growing AI browser in 2026 (175 percent QoQ versus Comet's 41 percent), and the trajectory implies Atlas may overtake Comet by user count in late 2026 if growth holds. Second, Memory continuity creates durable framing effects that single-session optimisation does not capture; brands with consistent positioning across queries earn structural Memory advantages versus brands with shifting positioning. Third, Atlas's agentic-task completion rate of 76 percent is the highest among AI browsers in Q1 2026, indicating Atlas users are increasingly delegating multi-step transactional tasks to the browser; Operator-friendly product page structure is leveraged investment for Atlas visibility.
Methodology
Statistics on this page are compiled from OpenAI's public disclosures, independent reporting on Atlas adoption, third-party analytics (web traffic, app analytics), and Presenc AI continuous monitoring of Atlas responses across approximately 2,900 prompts. Memory-influence figures are derived from controlled-comparison testing across Memory-enabled and Memory-disabled session pairs. Surface-volume figures are estimates with ±15 percent variance. Updated quarterly. Last update: April 2026.
How Presenc AI Helps
Presenc AI tracks Atlas brand visibility across address-bar searches, inline summaries, and agentic tasks, with separate Memory-aware diagnostics that surface durable framing effects single-session monitoring would miss. For brands targeting ChatGPT-using audiences and B2B buyers in long-cycle journeys, Atlas visibility is structurally important and Presenc AI provides the infrastructure to monitor and optimise it continuously.
