Claude Surpasses ChatGPT in Usage Rate, Nearly 70% Practice Vibe Coding [GMO Internet Group]

GMO Internet Group (Group Representative: Masatoshi Kumagai) announced the results of a survey conducted in June 2026, revealing that the adoption rate of generative AI in business operations across the group has reached 98.7%. Furthermore, Claude has seen a sharp increase to 73.4% in daily use of generative AI services, making it the top-used service. Group Representative Masatoshi Kumagai is also actively practicing vibe coding with Claude Code, and in the past two months, he has developed an application by having AI write 100,000 lines of code through trial and error, thereby solving his own challenges.

Survey Summary

As of June 2026, the overall adoption rate of generative AI in business operations is 98.7% (an increase of +0.9 points from the previous survey), with 89.3% (an increase of +5.6 points from the previous survey) of partners using it almost daily.

Monthly business reduction time is 432,000 hours, approximately 65.1 hours per person (an increase of +11.2 hours from the previous survey), achieving a reduction of over 11 hours compared to the previous survey three months ago.

The results show Claude used by 73.4%, followed by ChatGPT at 72.3%, and Gemini at 64.3% for daily generative AI services.

The effect of the "GMO AI Boost Subsidy" (*1) continues, with a significant increase in paid service contract rates to 89.5% (an increase of +16.0 points from the previous survey).

Including those who have "practiced in business" and "have tried" vibe coding (developing services and tools with AI), approximately 70% have experience. Furthermore, over 40% (40.8%) are practicing it in their business operations.

[GMO Internet Group's Generative AI Utilization Survey Results]

As of June 2026, the overall adoption rate of generative AI in business operations is 98.7% (an increase of +0.9 points from the previous survey).

98.7% of domestic partners (excluding shift workers) are utilizing generative AI (an increase of +0.9 points from the previous survey).

Regarding usage frequency, 89.3% are "using it almost daily" (an increase of +5.6 points from the previous survey).

Through the utilization of generative AI, a reduction of approximately 432,000 hours per month has been achieved, with a reduction of about 65.1 hours per person (an increase of +11.2 hours from the previous survey).

The results show Claude used by 73.4%, followed by ChatGPT at 72.3%, and Gemini at 64.3% for daily generative AI services.

While ChatGPT had the top usage rate previously, Claude has now surged to the top with a 73.4% usage rate.

The paid service contract rate also saw a significant increase to 89.5% (an increase of +16.0 points from the previous survey), indicating the successful penetration of the "GMO AI Boost Subsidy."

Including those who practice vibe coding in business and those who have tried it, 71.8% of people are practicing it, with 40.8% practicing it in their business operations.

71.8% of people are practicing vibe coding in their business operations or have tried it, meaning about 70% of partners have practical experience.

Specifically, those practicing it in their business operations have reached 40.8% (approximately 40%).

What did you feel still needed to be done by yourself (a human)?

Many responses continued to indicate that the final confirmation should be done by humans to prevent hallucinations, with particular caution advised for numerical data, dates, and legal information.

Many responses also continued to state that interpersonal tasks should be handled by humans. The limitations of AI's "empathetic" ability appear to be a common understanding among many partners.

Requests for coding to generative AI are on an increasing trend, but there were opinions that human review is essential due to incidents occurring from "over-reliance" as a real-life experience.

Partner Comments

<Please tell us if there was anything you felt still needed to be done by yourself (a human) when using AI.>

- "If the individual's attitude of researching and thinking, which is a prerequisite for AI utilization, is weak, relying on AI can lead to shallower thinking and paradoxically increase confirmation costs."

- "Complex communication that involves reading between the lines is difficult for AI."

- "AI can organize points and create a draft, but the responsibility lies with humans."

- "AI is overwhelmingly faster at code generation, but human review ensures quality. This is especially important for complex business logic."

What are the conditions for someone who is proficient in using generative AI?

"Achieving results in business" was the most frequent answer. "Achieving results" is increasingly valued as an evaluation criterion over simply "knowing."

"Being able to divide roles between humans and AI" was the next most common answer. The essence of proficiency is recognized as being able to appropriately divide tasks between AI and humans, rather than being completely dependent on AI.

High evaluations are also given to those who do not take AI outputs at face value, but rather test them with hypotheses and can explain them in their own words. Judgment and explanation skills are becoming established as prerequisites for AI literacy.

Partner Comments

<In your opinion, what kind of person do you think is proficient in using generative AI?>

- "Someone who can connect outputs to outcomes (business value) rather than just outputs. In an era where anyone can produce outputs, the ability to commit more to outcomes is important."

- "Someone who can distinguish between what to delegate to AI and what to decide for themselves. They can break down business tasks into processes, verbalize them in a format that AI can handle, and perform quality checks themselves without blindly accepting the output."

[Group Representative Masatoshi Kumagai's Comment]

GMO Internet Group is advancing towards hyper-automation in November 2027. I am personally at the forefront, promoting, executing, and leading by example in AI utilization. I believe that AI can bring about genuine transformation throughout an organization only when the management itself masters its use. I am practicing vibe coding with Claude Code and have personally developed an application called "Dream Fulfillment Cockpit" to solve my own challenges, which I continue to update daily.

Recognizing the reality that coding has already become an AI job rather than a human one, GMO Internet Group will review the organizational structure and operational methods of the entire company, including engineers. We will then transform into an "AI-nized" organization. All partners will solve their own challenges through vibe coding and maximize productivity through token management. This is the ideal for GMO Internet Group as a hyper-automation group.

[Leader of the Group's AI Promotion Project "AI Shiaouze!", Jangbae Lee's Comment]

From prompt engineering to context engineering and AI orchestration, and now into the era of loop engineering. The environment surrounding us is evolving at a dizzying speed.

From now on, our new job will be to rebuild the cycle itself where AI verifies, corrects, and re-executes. What is necessary to keep that loop running intelligently is a graph DB as a "second brain," and this is what I am most focused on right now. Knowledge connected by nodes and edges is recalled not by search but by "association," and the implicit knowledge of individuals is structured as organizational assets. In other words, it's a reproduction of synapses. Loops generate knowledge, graphs connect knowledge, and connected knowledge makes the next loop smarter—2026 will be an exciting year for transforming and improving the very intelligence of our organization through this cycle.

We have been promoting initiatives such as the AI reskilling program "Tora no Ana." In May 2025, we established the "GMO AI Boost Subsidy" with an annual investment of 1 billion yen (average of 10,000 yen per person per month) to promote AI utilization. Furthermore, in response to the rapid evolution of Claude, we have additionally invested 1.15 billion yen as "GMO AI Boost Subsidy for Claude" (*3). (February 2026)

Since January 2026, we have designated "GMO AI Day" (※4) as a day for all partners to concentrate and seriously engage with AI. Through these efforts, GMO Internet Group aims to become "the most hyper-automated company group in Japan" (*5) by fully utilizing AI agents by November 30, 2027.
