The artificial intelligence (AI) chatbot market has experienced an unprecedented “Big Bang” explosion, with an estimated 100 billion web visits to over 10,500 AI tools from August 2024 to July 2025.
A recent comprehensive study, “The AI’ Big Bang’ Study 2025,” reveals that just ten leading AI chatbots have captured a staggering 58.8 per cent of this traffic, collectively drawing 55.88 billion visits within a 12-month period. This signifies a period of rapid consolidation and maturation, transforming AI chatbots from experimental tools into essential digital infrastructure.
For Southeast Asia’s burgeoning tech ecosystem, these global trends offer critical insights into where user attention is consolidating and what strategies drive success in the competitive AI landscape.
ChatGPT maintains unchallenged supremacy
Despite the entry of numerous challengers, ChatGPT remains the undisputed leader, cementing its position as the global default for AI interaction. The OpenAI flagship recorded an unmatched 46.59 billion total web visits from August 2024 to July 2025, demonstrating a robust 106 per cent year-over-year growth.

ChatGPT’s market share is particularly noteworthy, accounting for 48.36 per cent of all AI web traffic among over 10,500 tools as of July 2025. To put this into perspective, the next nine chatbots combined make up only 10.45 per cent of the market. This sustained dominance highlights that ChatGPT is not merely a household name but has become a daily habit for users worldwide.
Grok’s meteoric rise disrupts the market
The most significant surprise of the year comes from Grok, developed by xAI and integrated into X (formerly Twitter). Despite being a late entrant, Grok ascended to the second spot in the weighted rankings, achieving an “astronomical leap” with 686.91 million total web visits. Its growth rate is truly unprecedented: a 1,343,408 per cent year-over-year traffic increase from virtually zero, making it the “fastest-rising star” and the “most significant breakthrough of the past 12 months”.
This explosive momentum is primarily attributed to its platform-native distribution via X and the high-profile backing of Elon Musk, providing instant reach and viral potential that standalone chatbots struggle to match.
Gemini emerges as a formidable challenger
Google DeepMind’s Gemini has steadily climbed to third place, solidifying its position as “ChatGPT’s closest rival”. It logged 1.66 billion total web visits, marking a substantial 156 per cent year-over-year increase. Gemini’s growth trajectory is characterised as “cleanest and steadiest,” mainly due to improved Google integration and user interface enhancements.
With its average monthly visits in the last quarter (May-July 2025) reaching 246.2 million, up by 77.63 per cent from its annual average, Gemini demonstrates “serious competitive intent”. It is methodically building the foundation to challenge for the second position by 2026.
Specialised strengths: Engagement, research, and enterprise
While the top three dominate in scale, other chatbots are carving out strong niches based on specialised strengths:
- Claude: Anthropic’s Claude leads in user engagement, boasting the highest average session duration of 16 minutes and 44 seconds per visit. This “superior engagement depth” signals that users turn to Claude for “thoughtful, extended conversations,” valuing quality over sheer volume. It achieved 1.15 billion visits and a 201 per cent growth rate year-over-year.
- Perplexity: Ranking sixth, Perplexity AI has established itself as the go-to AI chatbot for research-focused answers. It garnered 1.47 billion total web visits with a significant 227 per cent year-over-year growth, attracting users who prioritise “factual, citation-backed answers over conversational fluff”.
- Microsoft Copilot: Positioned seventh, Copilot showcases a different success model driven by enterprise integration. It recorded 957.19 million total web visits and a rapid 348 per cent year-over-year growth, primarily from business users leveraging its seamless integration across Microsoft 365 and Windows platforms. Despite having the shortest average session duration at 9 minutes and 4 seconds, this reflects efficient workplace usage rather than poor engagement, proving that “consistent integration across workflows matters more than lengthy chat sessions” in the B2B space.
The volatility factor: DeepSeek’s cautionary tale
DeepSeek recorded the “most explosive rise” in the study, surging to 2.74 billion total web visits with an unprecedented 48,848 per cent growth rate year-over-year. However, its trajectory highlights the challenge of maintaining viral momentum.

After peaking at 520.2 million visits in February 2025, DeepSeek’s web traffic experienced a steady decline, dropping 39.5 per cent over five months to 314.6 million by July. This “dramatic peak-and-valley pattern” serves as a “classic hype cycle,” underscoring that viral attention does not guarantee lasting success.
Media’s role and mobile traction
Media visibility plays a “key driver of traffic,” with the top AI chatbots collectively mentioned in over 7.7 million media articles from August 2024 to July 2025. Surges in press coverage often correlated with spikes in traffic, reinforcing the media’s role in shaping public adoption.
Mobile adoption is also a significant indicator, with these ten chatbots receiving a combined 40.6 million app store reviews across Apple App Store and Google Play, reflecting strong user engagement. Notably, Poe, despite a 46 per cent decline in web traffic year-over-year, maintains relevance through its “surprisingly loyal mobile user base” with 479,100 app store reviews, demonstrating a “web-to-mobile migration” strategy.
Meta AI: Big name, modest impact
Despite the immense resources and platforms (Facebook, Instagram, WhatsApp) of its parent company, Meta AI ranks tenth in the study, exhibiting “modest impact”. It logged 130.35 million web visits with a 468 per cent year-over-year growth, but its presence and adoption have “not lived up to expectations”.
Its low 38,300 app store reviews signify a struggle to generate buzz or user loyalty, highlighting a “mismatch between resources and real-world impact”. This contrasts sharply with Grok, which launched later but “outpaced Meta AI in nearly every metric”.
A consolidating market and evolving necessity
The AI chatbot landscape 2025 reflects explosive growth, fierce competition, and a clear trend of market consolidation. A small group of “dominant generalists” led by ChatGPT is solidifying its positions, while “rising challengers with specific strengths” like Grok, Gemini, and Claude are gaining ground.

Concurrently, “specialised tools” such as Perplexity and Microsoft Copilot are successfully carving out profitable niches by solving specific user problems exceptionally well.
The study unequivocally states that “AI chatbots have evolved from experimental toys to essential digital infrastructure”. Success increasingly hinges on platform integration and a refined distribution strategy, which are proving as crucial as technological advancements.
For tech startups and innovators across Southeast Asia, understanding these dynamics is paramount. It’s no longer a question of if these tools will be used, but which ones will best fit evolving needs in a future where human-AI collaboration becomes as natural as texting. The “AI chatbot Big Bang continues expanding,” and this is “only the beginning”.
