OpenAI is fighting back in the increasingly competitive enterprise artificial intelligence market as businesses expand their use of ChatGPT, Codex and other AI-powered workplace tools.
The company has been pushing aggressively into business AI after Anthropic gained an important lead in enterprise adoption earlier in 2026.
According to Ramp data published in May, 34.4% of surveyed businesses were paying for Anthropic services in April, compared with 32.3% for OpenAI. It was the first time Anthropic had moved ahead of OpenAI in verified business customers in the dataset.
But OpenAI’s latest enterprise data suggests the company is gaining momentum again, particularly as businesses move from simply asking AI questions toward using AI agents to complete actual work.
Anthropic Initially Took the Enterprise Lead
Anthropic’s rise in business AI adoption became one of the biggest developments in the AI market during the first half of 2026.
Ramp’s data showed Anthropic overtaking OpenAI among businesses paying for AI services in April.
The difference was relatively small, with Anthropic at 34.4% and OpenAI at 32.3%.
However, the result was significant because enterprise customers are generally considered particularly valuable to AI companies.
Businesses can purchase large numbers of seats and consume substantial amounts of API and AI-agent capacity.
OpenAI Still Has a Massive Business Footprint
Despite Anthropic’s temporary lead in Ramp’s adoption data, OpenAI already has an enormous enterprise customer base.
OpenAI announced in November 2025 that more than 1 million businesses around the world were directly using its products.
That figure included organizations paying for business use through ChatGPT workplace products or direct consumption of OpenAI models through its developer platform.
OpenAI has continued expanding that business ecosystem throughout 2026.
Enterprise Is Becoming a Bigger Part of OpenAI’s Business
OpenAI said in April 2026 that enterprise revenue accounted for more than 40% of its revenue and was on track to reach parity with consumer revenue by the end of the year.
The company also reported that Codex had reached 3 million weekly active users and that its APIs were processing more than 15 billion tokens per minute.
Those figures demonstrate how quickly OpenAI’s business strategy has expanded beyond the consumer ChatGPT chatbot.
ChatGPT Enterprise Is Becoming More Powerful
ChatGPT Enterprise is designed specifically for organizations.
The service provides centralized administration, enterprise privacy and security controls, advanced tools, usage insights and customization features.
Organizations can manage users and workspaces while providing employees with access to advanced AI capabilities.
OpenAI has also continued adding agentic tools and Codex functionality to its business offerings.
Enterprise AI Is Moving From Assistance to Execution
One of the biggest changes in business AI is the shift from simple assistance to actual task execution.
Employees initially used AI primarily to:
- Write emails
- Summarize documents
- Brainstorm ideas
- Answer questions
- Generate content
Now businesses are increasingly asking AI systems to perform multi-step tasks.
AI agents can search for information, work with files, use software tools and complete longer workflows.
OpenAI says this shift is becoming increasingly important among its enterprise customers.
Codex Is Driving Enterprise AI Growth
Codex has become one of OpenAI’s most important business products.
The AI coding system helps developers understand code, write software and complete programming tasks.
But OpenAI’s enterprise data shows that Codex usage is spreading beyond engineering.
Since February 2026, weekly active enterprise Codex users reportedly grew:
- 108× in legal
- 41× in sales
- 41× in recruiting
- 26× in marketing
- 5× in engineering
This indicates that agentic AI is expanding into departments that traditionally had little direct interaction with software-development tools.
Enterprise AI Is Becoming More Agentic
OpenAI reported that as of June 2026, agentic AI usage represented 64% of combined Codex and ChatGPT output tokens among enterprise customers.
That is a major shift from the traditional chatbot model.
Instead of simply generating answers, businesses are increasingly allowing AI systems to perform tasks using tools and organizational context.
ChatGPT Work Expands AI Beyond Developers
OpenAI is also trying to expand agentic AI beyond software engineers.
Its ChatGPT Work strategy is designed to allow employees across organizations to delegate substantive tasks to AI.
This could make AI useful for employees working in:
- Sales
- Marketing
- Recruiting
- Finance
- Legal
- Operations
- Research
- Customer support
The goal is to make AI a general workplace execution layer rather than simply a chatbot.
Why Enterprise Customers Matter
Enterprise customers can be particularly valuable because their AI usage can become deeply integrated into company workflows.
Once an organization connects AI to internal knowledge, software and business processes, switching providers can become more complicated.
That creates the possibility of longer-term customer relationships.
For OpenAI and Anthropic, winning these customers is therefore about much more than selling chatbot subscriptions.
Anthropic Still Has a Strong Position
OpenAI’s recent enterprise momentum does not mean Anthropic has lost its advantage.
Anthropic has built a strong reputation among developers and businesses, particularly through Claude and Claude Code.
Ramp’s data showed Anthropic leading OpenAI among businesses paying for AI services in April.
Anthropic has also benefited from strong adoption among technology, finance and professional-services companies.
Claude Code Is Anthropic’s Major Advantage
Claude Code has become one of Anthropic’s most important products.
The tool allows developers to use Claude as an AI coding agent capable of working through software projects.
Its success has helped Anthropic establish a strong position among developers and enterprise technology teams.
That creates direct competition with OpenAI’s Codex.
OpenAI and Anthropic Are Competing for the Same Enterprise Budgets
The enterprise AI market is becoming a direct battlefield between the two companies.
Businesses increasingly have to decide whether to spend their AI budgets on:
- ChatGPT
- Claude
- Codex
- Claude Code
- APIs
- AI agents
- Enterprise AI platforms
The competition is therefore shifting from model benchmarks to actual business adoption.
Privacy Is Becoming a Competitive Weapon
Data privacy is another major area of competition.
Businesses often handle sensitive information involving customers, employees, finances and intellectual property.
That makes data-retention policies extremely important.
OpenAI recently introduced a new safety approach called Private Safety Processing, designed to help detect misuse without retaining detailed customer interaction data.
The system is being tested with enterprise and API customers.
OpenAI Is Trying to Differentiate on Data Control
OpenAI’s new privacy approach could become an important selling point for businesses that are concerned about sensitive information.
The company is also working on ways for customers to maintain greater control over their data.
For highly regulated industries such as healthcare and finance, these controls could influence which AI provider a company chooses.
Anthropic Is Also Changing Its Enterprise Data Policy
The privacy battle is not one-sided.
Anthropic is reportedly planning changes to its enterprise data-retention policy that would give business customers greater control over their data.
The company is also preparing a new safety system later in 2026.
This demonstrates how important enterprise security and privacy have become in the AI market.
The Enterprise AI Race Is About More Than Chatbots
The competition between OpenAI and Anthropic is increasingly moving beyond chatbot quality.
Businesses are evaluating AI providers based on:
- Reliability
- Security
- Privacy
- Cost
- Model performance
- Agent capabilities
- Integrations
- Developer tools
- Administrative controls
This means the winner may not necessarily be the company with the best-performing chatbot.
The winner could be the company that becomes most deeply integrated into everyday business operations.
OpenAI Has a Major Distribution Advantage
ChatGPT already has enormous consumer recognition.
That gives OpenAI an important advantage when businesses introduce AI tools to employees.
Many workers are already familiar with ChatGPT from personal use.
OpenAI has described this consumer-to-enterprise transition as an important part of its workplace growth.
Employees often bring the tools they already know into professional environments.
Consumer Adoption Can Lead to Enterprise Adoption
OpenAI says more than 700 million people were using ChatGPT weekly in its January 2026 workplace research.
The company argues that widespread consumer adoption is helping accelerate workplace adoption.
This creates a powerful distribution effect.
Employees already familiar with ChatGPT may require less training when companies officially deploy it.
Anthropic Has a Different Advantage
Anthropic has built much of its recent enterprise momentum around professional and developer use.
Claude’s reputation for reasoning and coding has helped the company gain traction in organizations that use AI for technical and knowledge-intensive work.
Claude Code has been particularly important in this strategy.
AI Coding Is Becoming a Major Enterprise Market
Software development is one of the areas where businesses are seeing some of the most immediate value from AI agents.
AI coding tools can help developers:
- Write code
- Debug software
- Understand large codebases
- Generate tests
- Refactor applications
- Investigate technical problems
- Automate repetitive engineering tasks
Both OpenAI and Anthropic are aggressively competing in this market.
OpenAI Wants AI Agents Everywhere
OpenAI’s enterprise strategy increasingly centers on agents.
The company’s research shows that organizations at the frontier of AI adoption are moving from using models for assistance toward delegating work to AI systems.
This could eventually transform AI from a productivity tool into an operational layer for businesses.
The Next Battle Could Be Enterprise AI Agents
The next stage of competition may therefore involve which company can build the most useful and reliable enterprise agents.
A successful agent could potentially:
- Understand a business request.
- Search company information.
- Analyze documents.
- Use software applications.
- Make recommendations.
- Complete actions.
- Report the results.
That is significantly more valuable than simply answering a question.
Businesses Are Becoming More Comfortable With AI
Enterprise adoption is also benefiting from greater familiarity with AI.
Employees who have already used AI personally are increasingly comfortable using it professionally.
Companies are now building policies, training programs and governance systems around AI.
This is creating a more mature enterprise market.
AI Governance Is Becoming Essential
As AI systems gain the ability to take actions, companies need stronger controls.
Organizations need to know:
- What the AI can access
- What actions it can perform
- Which employees can use it
- What data it can process
- How activity is monitored
- How sensitive information is protected
Enterprise AI platforms are therefore increasingly competing on governance and administration.
ChatGPT Enterprise Offers Centralized Controls
ChatGPT Enterprise provides centralized workspace management and administrative capabilities.
Organizations can control access, manage members and monitor usage through enterprise analytics.
OpenAI’s workspace analytics tools allow administrators to examine adoption and engagement trends across their organization.
The Financial Stakes Are Huge
The enterprise AI market could become one of the largest sources of revenue for AI companies.
Businesses are willing to spend substantial amounts when AI tools deliver measurable improvements in productivity.
This creates a major opportunity for both OpenAI and Anthropic.
But it also means investors will closely monitor enterprise customer growth.
OpenAI Needs to Maintain Its Momentum
OpenAI’s enterprise business is growing rapidly, but the company faces intense competition.
Recent financial reporting showed that Anthropic’s revenue growth has been particularly strong, with the company surpassing OpenAI in quarterly revenue during the second quarter of 2026.
That makes enterprise growth even more important for OpenAI.
Anthropic Is Not Standing Still
Anthropic is also continuing to improve its enterprise offering.
Claude Code, enterprise security and data controls are all part of the company’s effort to build deeper relationships with businesses.
The competition is therefore likely to remain intense.
The AI Enterprise Market Could Support Multiple Winners
Despite the rivalry, there may be enough demand for multiple major AI platforms.
Large companies may use more than one AI provider depending on the task.
For example, a company might use:
- ChatGPT for general workplace productivity
- Claude for specialized reasoning
- Codex for software development
- Gemini for Google Workspace integration
This multi-model strategy could become common among large enterprises.
The Future Could Be Multi-Model
Companies may increasingly avoid relying on a single AI provider.
Instead, they could route different tasks to different models.
This would allow businesses to optimize for:
- Cost
- Accuracy
- Speed
- Privacy
- Specialized capabilities
OpenAI and Anthropic will therefore need to compete not only for exclusive customers but also for a larger share of each customer’s AI workload.
What Happens Next?
OpenAI will likely continue expanding ChatGPT Enterprise, Codex and agentic capabilities.
Anthropic will continue investing in Claude, Claude Code and enterprise data controls.
Both companies are also likely to compete aggressively on pricing, security and model performance.
The next major battleground will be AI agents capable of performing meaningful business tasks with minimal human supervision.
Final Verdict
OpenAI is making significant progress in enterprise AI even as Anthropic has gained ground among business customers.
Anthropic briefly overtook OpenAI in Ramp’s April 2026 business-adoption data, with 34.4% of surveyed businesses paying for Anthropic compared with 32.3% for OpenAI.
But OpenAI’s latest enterprise data shows a rapidly expanding business ecosystem, particularly around Codex and agentic AI.
OpenAI says enterprise agentic usage is increasingly shifting from simple assistance toward actual task execution, while weekly Codex usage has grown dramatically across departments such as legal, sales, recruiting and marketing.
The battle between OpenAI and Anthropic is therefore entering a new phase.
The question is no longer simply which company has the smarter chatbot.
It is increasingly about which AI platform businesses will trust to perform real work.
If OpenAI can convert its enormous ChatGPT user base and growing enterprise adoption into deeper agentic workflows, it could regain a stronger position against Anthropic.
But Anthropic’s momentum in enterprise adoption and Claude Code means the competition is far from over.
