ChatGPT Enterprise Usage Explodes 8x in Just Months, OpenAI Reports

OpenAI's first State of Enterprise AI 2025 report, released on December 8, 2025, shows a dramatic rise in ChatGPT Enterprise activity.

Weekly message volumes have increased eight times since November 2024, based on data from over one million business customers and a survey of 9,000 workers across nearly 100 companies.

This growth marks AI's shift from testing to essential business operations, with OpenAI holding a strong lead at 36% market share in U.S. businesses, far ahead of competitors like Anthropic at 14.3%.

Explosive Growth in Key Metrics

The report details broad expansion in user numbers and deeper tool integration.

Enterprise seats have grown nine times, now exceeding seven million, while API reasoning tokens per organization jumped 320 times, pointing to more complex applications.

Custom Tools Drive Engagement

Custom GPTs and projects see 19 times more weekly users, making up 20% of enterprise messages.

These tools help embed company-specific knowledge, boosting efficiency across sectors.

Boosting Productivity Across Roles

Workers save 40 to 60 minutes daily on average, with data scientists and engineers gaining up to 80 minutes.

Three-quarters of users complete tasks faster and handle work once out of reach, such as non-technical staff writing code.

Sector-Specific Gains

Tech leads with 11 times customer growth, followed by healthcare at eight times and manufacturing at seven.

Professional services, finance, and tech show the highest usage volumes.

Real-World Business Examples

Companies like Intercom resolve 53% of customer calls with AI agents, cutting response times by 48%.

Lowe's AI assistants double online sales conversions, while Indeed boosts job applications by 20% and hires by 13% through AI invites.

Financial and Operational Wins

BBVA uses over 4,000 custom GPTs for operations, automating 9,000 legal queries yearly.

Oscar Health answers 58% of benefits questions instantly, and Moderna shortens product analysis from weeks to hours, speeding research decisions.

Navigating Challenges in a Competitive Landscape

Despite gains, adoption varies, with top users generating twice the messages per seat. Global growth is strong, especially in Japan for API use, but compute demands raise sustainability issues.

OpenAI faces threats from Google's Gemini, prompting internal focus on core strengths.

Editor's Comments

OpenAI's enterprise surge strengthens its position in AI, building on past innovations like GPT models that transformed natural language processing.

This growth aligns with broader trends where AI drives revenue gains, as seen in studies showing 1.7 times higher growth for adopters.

However, uneven rollout risks widening gaps between leading firms and others. Looking ahead, expect AI to evolve into seamless "virtual teams," but success depends on addressing energy needs and ethical integration, potentially reshaping global economies by 2030.
