ChatGPT vs Gemini: The quiet reset of the AI attention economy

In 2025, consumer AI moved from experimentation to everyday use. The latest Similarweb data indicates not a collapse of demand, but a recalibration of attention. Traffic to ChatGPT has eased after an extraordinary run, while Google’s Gemini has remained steady, quietly expanding its share. Together, the two platforms still command hundreds of millions of users globally, but the trend suggests the market is entering a more competitive and selective phase.

Between early December 2025 and the first week of January 2026, ChatGPT’s average daily visits fell by approximately 22 per cent, from roughly 203 million to around 158 million. Over the same period, Gemini’s daily traffic remained largely flat, at about 55 to 60 million visits. The narrowing gap is not due to a dramatic surge in Gemini, but rather to ChatGPT’s growth curve beginning to flatten after a period of near-uninterrupted expansion.

Even so, scale continues to favour ChatGPT. In December 2025 alone, it recorded 5.517 billion visits worldwide, more than three times Gemini’s 1.735 billion. That volume keeps ChatGPT among the world’s most visited digital destinations, reflected in its global rank of eight compared with Gemini’s rank of twenty-seven. Within the US AI chatbots and tools category, ChatGPT remains number one, with Gemini in second place.

Engagement becomes the new battleground

The story becomes more nuanced when considering user behaviour once they arrive. Although Gemini attracts fewer users, they spend more time per session and consume more content. Average visit duration on Gemini is just over seven minutes, compared with around six and a half minutes on ChatGPT. Pages per visit also favour Gemini at 4.3, versus ChatGPT’s 3.79, while bounce rates are marginally lower.

These differences may seem incremental, but at scale they carry significant implications for the market. Gemini is beginning to attract users who stay longer and explore more deeply, indicating a more deliberate usage pattern. ChatGPT, by contrast, continues to dominate total consumption. Its 20.9 billion page views in December dwarf Gemini’s 7.469 billion, emphasising that reach and frequency remain its core strengths.

Industry analysts tracking these patterns note that this split reflects two distinct modes of adoption. ChatGPT has become a habitual starting point for a broad range of tasks, whereas Gemini is increasingly used for more focused sessions, supported by Google’s emphasis on multimodal understanding across text, images, audio and video.

One of the clearest signals in the data concerns how users are accessing these platforms. For both ChatGPT and Gemini, more than three-quarters of traffic comes directly, rather than via search, social media or referrals. Gemini’s share of direct traffic stands at just over 77 per cent, with ChatGPT close behind at nearly 77 per cent. Such a high level of direct access is typically associated with utility platforms rather than media products. Users are not discovering these tools, they are returning to them.

This pattern is reinforced by device behaviour. Approximately 72 per cent of Gemini usage and 71 per cent of ChatGPT usage occurs on desktop, with mobile accounting for the remainder. For the time being, the AI chatbot remains primarily anchored in work, study and productivity contexts, rather than casual mobile browsing.

Geographically, the concentration of demand remains largely familiar. The United States accounts for just over 16 per cent of traffic, followed by India at slightly over nine per cent, with Brazil, Japan and the United Kingdom rounding out the top five. Across these markets, ChatGPT retains the larger share, particularly in the US and UK, while Gemini’s relative strength is more evident in regions where Google’s ecosystem is deeply embedded.

Distribution Power and the Rise of AI-to-AI Traffic

Another notable shift in the data is how AI platforms are beginning to route traffic to one another. ChatGPT now directs significant volumes of outbound traffic to other AI destinations. In December, its top destinations included Grok, Gemini itself, and several enterprise and academic services. All of this outbound traffic is attributed entirely to ChatGPT, signalling that it is already functioning as a distribution layer within the AI ecosystem.

Referral data further emphasises how closed these ecosystems have become. OpenAI’s own properties account for more than half of ChatGPT’s referral traffic, while Google surfaces generate the overwhelming majority of Gemini’s referrals. External publishers play only a minor role. Analysts caution that these figures capture only web-based usage and do not reflect embedded assistants or API-driven interactions, yet they still provide a clear view of where direct attention is concentrating.

What the slowdown really means

Seasonality contributes to the recent dip, as December holidays typically temper overall online activity. However, the steadiness of Gemini’s traffic during this period, alongside ChatGPT’s decline, suggests a more structural shift. After dominating with an estimated 86 per cent share of tracked chatbot traffic a year ago, ChatGPT now accounts for approximately 64.5 per cent. Over the same period, Gemini has grown from a low single-digit share to more than 21 per cent.

Other players remain far smaller by comparison. DeepSeek, Grok and Perplexity together account for only a fraction of total visits, underscoring how concentrated the consumer AI market continues to be. Yet their presence indicates that the category is broadening, even as attention consolidates around general-purpose assistants.

The business implication is not that ChatGPT is losing relevance, but that the market is maturing. Growth is becoming increasingly difficult to sustain through novelty alone. Engagement quality, integration depth and ecosystem leverage are beginning to matter more than raw scale.

A market entering its next phase

For brands and platforms seeking to understand how AI is reshaping discovery and demand, these figures provide a useful, albeit incomplete, snapshot. They reveal where direct web-based attention is flowing, which assistants are becoming default interfaces, and how user behaviour is evolving. They do not capture usage within apps, browsers or enterprise tools, where much of the next wave of growth is likely to occur.

What is clear is that the AI race is no longer solely about being first or largest; it is about becoming indispensable. ChatGPT continues to serve as the front door for much of the world, while Gemini is steadily furnishing the rooms beyond it. The coming quarters will reveal whether this narrowing gap represents a temporary adjustment or marks the beginning of a more balanced AI attention economy.
