ChatGPT vs Google Gemini Statistics 2026: Users, Revenue and Market Share

More than 800 million people use ChatGPT every week, with the platform crossing 900 million weekly active users by late February 2026, per OpenAI. Google Gemini reached 650 million monthly active users by November 2025. AI Overviews powered by Gemini now reach more than 2 billion users per month through Google Search, per Alphabet’s Q4 2025 earnings call. The ChatGPT vs Google Gemini statistics below track the numbers behind that asymmetry.

Web Traffic Market Share Comparison

• ChatGPT holds approximately 68% of the AI chatbot web traffic market share as of January 2026, down from 87.2% in January 2025, per Similarweb.
• Google Gemini holds approximately 18.2% of the AI chatbot web traffic market share as of January 2026, up from 5.4% a year earlier.
• First Page Sage’s April 2026 measurement places ChatGPT at 60.4% and Gemini at 15.2%, with Microsoft Copilot at 14.4%, Claude at 4.2%, and Perplexity at 2.8%.
• Gemini’s market share has nearly tripled in twelve months, rising from 5.7% in early 2025 to 15.2% by April 2026.
• ChatGPT’s web-traffic share fell 19.2 percentage points over the twelve months from January 2025 to January 2026, per Similarweb.

Sources: Similarweb and FirstPageSage

The two trackers disagree on absolute share but agree on direction: ChatGPT is losing web visits, Gemini is gaining them.

By the numbers: Similarweb measures ChatGPT at approximately 68% of AI chatbot web traffic in January 2026 and Gemini at approximately 18.2%. First Page Sage’s April 2026 panel puts the two at 60.4% and 15.2%, with Gemini’s share nearly tripling from 5.7% a year earlier.

Annual Revenue and Run Rate

• OpenAI hit $25 billion in annualized revenue in February 2026, up from $20 billion at the end of 2025.
• CFO Sarah Friar confirmed OpenAI’s full-year 2025 figure at $20 billion, alongside $6 billion in 2024 and $2 billion in 2023.
• Google Cloud’s annual revenue exceeded $50 billion for 2025, with Vertex AI and Gemini deployments driving growth, per Alphabet’s Q4 2025 earnings call.
• Total enterprise large language model spend reached $8.4 billion in 2025, per Menlo Ventures.
• OpenAI’s $25 billion annualized revenue divided across 900 million weekly active users works out to roughly $27.78 per weekly user, a direct-monetization yardstick that Gemini does not publish.

Key finding: OpenAI’s revenue ran from $2 billion in 2023 to $25 billion annualized by February 2026, a 12.5-fold increase in three years. Alphabet does not disclose Gemini-specific revenue; most monetization runs through AI Overviews ad inventory inside Search.

How does ChatGPT pricing compare with Gemini Advanced?

OpenAI prices ChatGPT Plus at $20 per month, ChatGPT Team at $25 per user per month, and ChatGPT Pro at $200 per month. Google prices Gemini Advanced at $19.99 per month inside Google One AI Premium, with 2 TB of cloud storage included, plus Gemini Business at $20 per user per month via Workspace. Consumer tiers are within a dollar of each other; the meaningful gap is at the power-user tier, where ChatGPT Pro at $200 has no direct Gemini equivalent.

Enterprise Adoption and Fortune 500 Penetration

• 93% of Fortune 500 companies now use OpenAI products as of late 2025, up from 80% in 2024.
• Microsoft separately reported generative AI deployment in 85% of Fortune 500 companies through its platforms, much of which incorporates OpenAI models via Azure OpenAI Service.
• 78% of Global 2000 enterprises use OpenAI models in production, per Andreessen Horowitz’s survey of 100 CIOs at Global 2000 companies.
• Over 70% of Google Cloud customers actively use Gemini, with 13 million developers building applications on the platform.
• OpenAI now holds 25% of the enterprise large language model market share by usage, the second-largest share, per Menlo Ventures.
• OpenAI held 50% of the enterprise market share by usage just two years ago, before the multi-model shift.
• 81% of enterprises run three or more model families concurrently, ending single-vendor AI procurement.

OpenAI sells direct to Fortune 500 IT buyers; Google rides Google Cloud’s footprint.

Why it matters: Survey data from Menlo Ventures shows 81% of enterprises run three or more model families concurrently, with the multi-model approach now the default in enterprise procurement. Single-vendor AI strategy is dead in regulated industries, so the ChatGPT-vs-Gemini decision rarely settles in any one procurement contract.

Accuracy Benchmarks: MMLU, GPQA, SWE-Bench

• On the MMLU benchmark, Gemini 3.1 Pro Preview leads at 94.1%, followed by GPT-5.2 at 91.4%, per the LM Council’s benchmark suite.
• MMLU is now considered saturated at 88-94% for top models and no longer differentiates frontier models.
• Frontier labs increasingly rely on GPQA Diamond, SWE-bench Verified or SWE-bench Pro, AIME 2025, ARC-AGI 2, and Humanity’s Last Exam for benchmark differentiation.
• Gemini’s MMLU lead at 94.1% vs 91.4% is real but functionally tied; both models saturate the benchmark.

Worth noting: MMLU now saturates at 88-94% for top models, with Gemini 3.1 Pro Preview at 94.1% and GPT-5.2 at 91.4%, per the LM Council’s benchmark suite. Capability rankings shift every few months, while public perception of model leadership tracks the older numbers (see Claude vs ChatGPT data).

Coding and Reasoning Benchmarks Head-to-Head

• On Terminal-Bench 2.0, Claude Opus 4.6 holds the industry-leading score at 65.4%, per the LM Council benchmark suite.
• SWE-bench Verified and SWE-bench Pro are among the benchmarks that frontier labs increasingly rely on for model differentiation.
• AIME 2025 and ARC-AGI 2 are among the benchmarks frontier labs rely on for model differentiation, alongside GPQA Diamond and Humanity’s Last Exam.
• Coding is the active frontier of model differentiation, since enterprise contracts hinge on IDE integration and agentic workflows.

• Forward indicators point to a multi-model equilibrium.

Common Questions

How many users does ChatGPT have vs Gemini in 2026?

ChatGPT reports 900 million weekly active users as of February 27, 2026, per OpenAI. Google Gemini reaches 650 million monthly active users as of November 2025, per Google. Gemini-powered AI Overviews separately reach more than 2 billion users monthly through Google Search, per Alphabet’s Q4 2025 earnings call. The comparison depends on whether you count the chatbot surface or the embedded assistant.

Which has higher revenue, ChatGPT or Google Gemini?

OpenAI reports $25 billion in annualized revenue as of February 2026, up from $20 billion at the end of 2025. Google Cloud’s annual revenue exceeded $50 billion for 2025, with strong growth from Vertex AI and Gemini deployments, per Alphabet’s Q4 2025 earnings call. Alphabet does not separately disclose Gemini-specific revenue in this report. OpenAI runs a direct-revenue model; Google embeds Gemini monetization inside Search ads and Cloud subscriptions, making like-for-like comparison hard.

Conclusion

The ChatGPT vs Google Gemini statistics for 2026 show two competitors built on different distribution mechanics, with the asymmetry visible across every metric. ChatGPT serves 900 million weekly active users. OpenAI’s annualized revenue run rate reached $25 billion. Google Gemini reaches 650 million monthly active users as of November 2025, per Google. AI Overviews powered by Gemini reach more than 2 billion users monthly through Google Search. 93% of Fortune 500 companies use OpenAI products as of late 2025. Over 70% of Google Cloud customers actively use Gemini, with 13 million developers building on the platform.

ChatGPT’s web-traffic share fell 19.2 percentage points in twelve months, from 87.2% to approximately 68%, per Similarweb. 81% of enterprises run three or more model families concurrently. The single-vendor era is over. Buyers route workloads across multiple chatbots, so the ChatGPT-vs-Gemini decision is rarely winner-take-all.
