1 million business customers: the fastest-growing business platform in history
TL;DR: OpenAI has reached 1 million business customers globally—the fastest-growing business platform in history—with category leaders including Amgen, Commonwealth Bank, Booking.com, Cisco, Lowe’s, Morgan Stanley, T-Mobile, Target, and Thermo Fisher Scientific. ChatGPT Enterprise seats grew 9x year-over-year, with 7 million total ChatGPT for Work seats deployed (up 40% in two months).
Consumer adoption fuelling enterprise momentum
OpenAI announced today that more than 1 million business customers worldwide are directly using OpenAI products—either through ChatGPT for Work or through direct model consumption via the developer platform. This milestone encompasses all organisations actively paying OpenAI for business use.
The company attributes its enterprise momentum partly to widespread consumer adoption. With more than 800 million weekly users already familiar with ChatGPT, adoption and ROI within businesses is realised more rapidly. Pilots are shorter and rollouts face less friction compared to traditional enterprise software deployments.
This dynamic is reflected in ChatGPT for Work growth: the platform now has more than 7 million total seats, up 40% in just two months. ChatGPT Enterprise seats specifically have grown 9x year-over-year, demonstrating accelerating enterprise adoption.
New enterprise capabilities driving full-scale deployment
To support this acceleration, OpenAI has launched a wave of tools, integrations, and capabilities designed to help teams move from early experimentation to full-scale deployment:
Company knowledge integration
OpenAI introduced company knowledge, enabling ChatGPT to reason across tools like Slack, SharePoint, Google Drive, and GitHub to get answers, perform analysis, and take action using a version of GPT-5 optimised for working with tools and providing citations.
Codex adoption surge
Codex, OpenAI’s model for code generation, refactoring, and workflow automation, has seen usage increase 10x since August. Organisations like Cisco have rolled out Codex into engineering workflows, cutting code review times by 50% and shrinking project timelines from weeks to days.
AgentKit for rapid agent development
AgentKit makes enterprise agents practical to build and deploy, enabling teams to progress from idea to production in days instead of months. Private equity firm Carlyle reports the AgentKit evaluation platform cut development time on their multi-agent due diligence framework by over 50% whilst improving agent accuracy by 30%.
Multimodal workflow expansion
OpenAI has advanced multimodal models to enable richer workflows, from the Image Generation API and Sora 2 for visual and video creation to gpt-realtime and Realtime API for building production voice agents. Teams across industries can now work across text, images, video, and audio in one unified system.
75% of enterprises report positive ROI
According to a recent Wharton study, 75% of enterprises report a positive ROI from AI deployments, with fewer than 5% reporting negative returns. Whilst numerous studies examine this topic, OpenAI notes this research reflects what they observe with customers: when AI is deployed with the right use case and infrastructure, teams see tangible results.
Indeed: 20% application increase, 13% hiring lift
Indeed is using OpenAI APIs in its Invite to Apply feature, driving a 20% increase in applications and a 13% lift in hires—demonstrating measurable impact on core business metrics in recruitment.
Lowe’s: Empowering 1,700+ stores
Lowe’s empowers all associates in 1,700+ stores with expert project guidance through Mylow Companion, an in-store app built with OpenAI models, democratising product expertise across the retail workforce.
Intercom: Quarters to days
With OpenAI as the backbone of Fin, their customer service agent, Intercom has accelerated development cycles from quarters to days—a dramatic compression in time-to-market for new capabilities.
Databricks: Native OpenAI integration
Starting today, Databricks is bringing OpenAI frontier intelligence to where enterprises’ data already lives, making it easier to build and run high-quality agents within existing data infrastructure.
Beyond internal adoption: Building on the platform
Beyond internal enterprise adoption, OpenAI observes a second trend: businesses increasingly want to build new applications and agentic workflows directly on the OpenAI platform.
Apps in ChatGPT
Companies including Canva, Figma, Zillow, and Spotify have plugged their applications directly into ChatGPT to meet users where they already are, creating integrated experiences within the ChatGPT interface.
Agentic Commerce Protocol
Shopify, Etsy, Walmart, PayPal, and Salesforce are building new shopping experiences through the Agentic Commerce Protocol (ACP) in ChatGPT, bringing conversational commerce into the flow of everyday decisions and transforming how consumers discover and purchase products.
Rethinking the operating system for work
OpenAI expresses gratitude to customers building with them today whilst looking forward to developments in 2026 and beyond. The company identifies a significant opportunity to rethink the operating system for work and remains committed to building the platform to power this transformation.
The milestone of 1 million business customers—achieved faster than any previous business platform—suggests the fundamental shift from AI as experimental technology to AI as essential infrastructure for modern organisations. The combination of consumer familiarity, enterprise-grade capabilities, and demonstrable ROI creates conditions for continued rapid adoption across industries and geographies.
