Digital Transformation VerticalOctober 2025 Policy Research Working Paper11231 Abstract creating stark global divides. While 24 percent of internetusers in high-income countries use ChatGPT, penetrationdrops to 5.8 percent in upper-middle-income countries,4.7 percent in lower-middle-income countries, and just0.7 percent in low-income countries. Regression analysisconfirms that gross domestic product per capita stronglypredicts adoption growth. Fifth, localization shapes com-petitive advantage: non-U.S. tools concentrate heavily inhome markets, with Le Chat drawing 69 percent of traf-fic from Europe and several Chinese tools exceeding 90percent domestic usage. These patterns reveal an artificialintelligence landscape characterized by intense innovation,persistent market leadership, accelerating growth, and deep-ening global inequality, underscoring the need for inclusivepolicies as generative artificial intelligence becomes centralto economic participation. Nearly three years after ChatGPT’s launch, the generativeartificial intelligence landscape remains in rapid flux. Usinghigh-frequency website traffic data from Semrush, this papertracks global adoption patterns for the 60 most-visited con-sumer-facing generative artificial intelligence tools throughmid-2025. Five key findings emerge. First, fierce competi-tion drives continuous innovation: two of 2025’s top fivetools—DeepSeek and Grok—are new entrants, and devel-opment is rapidly diversifying into multi-modal capabilities,reasoning, and specialized applications. Second, ChatGPTmaintains dominance despite competition, accounting for77 percent of traffic to the top 60 tools in April 2025. Third,usage of generative artificial intelligence has exploded sincemid-2024: ChatGPT traffic grew 113 percent year-over-year, driven by 42 percent user growth and 50 percentincreased visits per user, with session duration doubling.Fourth, high-income countries are pulling decisively ahead, This paper is a product of the Digital Transformation Vertical.

Who on Earth Is Using Generative AI? GlobalTrendsandShiftsin2025∗ YanLiu†1,JingyunHuang‡12,andHeWang§1 1WorldBank 2RiceUniversity JEL codes:O30, O31, O14 1Introduction Nearly three years after the launch of ChatGPT, generative AI (GenAI)1continues to capture globalattention.User interest has surged, firms are ramping up investments in workforce training andGenAI integration, and governments are increasingly active in shaping AI governance frameworks.In 2024, we publishedWho on Earth is Using Generative AI?(Liu and Wang 2024)—the firststudy to leverage website traffic data to provide real-time, cross-country insights into GenAI usagepatterns and the country-level factors influencing adoption. Since then, the GenAI landscape has evolved significantly. New entrants such as DeepSeek andGrok have expanded the field, while established players have released powerful new models andcapabilities, including OpenAI’s GPT-4o Mini and SearchGPT. Multimodal tools—especially foraudio and video generation—have flourished, with platforms like ElevenLabs gaining traction andOpenAI’s Sora becoming publicly accessible. Meanwhile, GenAI models have become both morecapable and more affordable, with advances in reasoning, interactivity, and deployment efficiency. These developments call for an updated analysis.This paper builds on our earlier work andpresents fresh evidence on how GenAI adoption patterns have shifted through mid-2025, offeringnew insights into global usage trends, the diffusion of new tools, and the evolving AI adoptiondivide. To track GenAI adoption globally, we continue to rely on high-f
