ChatGPT Surges in Enterprises, Challenging Microsoft Copilot in Office Automation

ChatGPT is rapidly emerging as the preferred AI assistant for office automation, even as Microsoft continues to pour billions into Copilot and expands its integration across the Microsoft 365 ecosystem. Recent reports from industry sources and user anecdotes reveal a pronounced and unexpected shift in enterprise behavior: employees, often of their own accord, are choosing OpenAI’s ChatGPT over Microsoft’s Copilot—even in organizations that have formally adopted Copilot across thousands of seats. This development signals not only a changing landscape in AI-powered workplace productivity, but also a subtle but significant rivalry brewing between long-standing partners OpenAI and Microsoft.

The Corporate Shift Toward ChatGPT​

In interviews with executives and IT administrators from major firms, the story that emerges is often one of grassroots preference. Amgen, a global biopharmaceutical company, exemplifies this trend. After purchasing Copilot licenses for 20,000 employees, Amgen found that within a year, staff had begun advocating for—and increasingly adopting—ChatGPT for day-to-day tasks. “ChatGPT is simply more convenient, faster, and more enjoyable to use,” a representative explained, echoing sentiments widely shared among end users.
The pharmaceutical giant’s story isn’t isolated. At Bain & Co., despite a close and publicized partnership with Microsoft, over 16,000 employees regularly turn to ChatGPT, while only a fraction—around 2,000—make use of Copilot, with most restricted to using it alongside Excel. New York Life has taken the more diplomatic route, allowing employees to choose between the two AI assistants, delaying any definitive selection until usage data and internal feedback can better inform the ultimate decision.
These patterns reflect a fundamental truth in office automation today: while enterprise contracts and technical integrations matter, usability, speed, and user familiarity carry enormous weight in the adoption of AI assistants.

Analyzing the Underlying Drivers​

Several factors are fueling ChatGPT’s ascendancy, even in environments where Copilot boasts a technical head start thanks to its deep integrations with Outlook, Teams, Excel, and other Microsoft 365 services.

1. Familiarity Breeds Preference​

One of the most cited reasons by users is familiarity. Many office workers were exposed to, and grew comfortable with, ChatGPT in their personal lives long before their organizations rolled out Copilot. This informal pre-training has powerful downstream effects: users default to what they know and trust, rarely opting to switch to something that feels redundant or marginally different. As ChatGPT updates are pushed to the public more quickly than Copilot—and with branding squarely aligned to “cutting-edge AI technology”—it’s seen as the direct conduit to the latest innovation.

2. Speed and User Experience​

In user surveys and anecdotal feedback, ChatGPT’s interface is routinely described as more streamlined, with snappier responses and fewer frustrating delays. While Copilot offers the promise of in-context awareness—surfacing insights from emails, files, and calendars—this added integration often leads to more complex user flows. For employees whose primary AI needs revolve around research, content drafting, or rapid information synthesis, ChatGPT reportedly “just feels faster.” The perception of being a direct line to the “best AI” is difficult to shake, especially when updates or new capabilities debut first on ChatGPT, then trickle down to Copilot after additional vetting and compliance checks.

3. Flexibility in Pricing and Access​

At the executive level, cost remains a major factor. Microsoft’s Copilot for Microsoft 365 continues to be priced at $30 per user per month, while ChatGPT Enterprise has typically come in at around $60 per seat. However, OpenAI’s move to test flexible, usage-based pricing has upended the equation. Companies with wide but uneven use patterns often find such models more fiscally attractive than a flat, per-seat approach. This dynamic pricing is particularly compelling for businesses evaluating long-term scalability and return on investment.

4. Perceived Value vs. Integration Depth​

Microsoft’s key differentiator for Copilot remains its seamless weaving into Outlook, Teams, Word, and Excel, allowing for AI-powered features directly in the apps where employees already work. For some tasks, this context-sensitive intelligence is indispensable. Still, as several organizations have discovered, the perceived value of such depth may not outweigh the friction of learning a new tool—especially when many AI tasks don’t require deep integration with business documents and emails.

The View from Microsoft: Successes Amidst Stiff Competition​

While the narrative of ChatGPT overtaking Copilot resonates with many end users and rank-and-file employees, Microsoft is hardly on the ropes. Corporate adoption statistics paint a more nuanced picture. More than 100,000 paid users at Barclays, Accenture, and Volkswagen are actively using Copilot, according to recent statements from Microsoft. And as organizations further embed AI in critical business workflows—beyond ad-hoc queries and text drafting—the integration strengths of Copilot become more attractive.
Microsoft has also made strategic moves to expand Copilot’s presence: launching versions for macOS, introducing Copilot for Gaming on iOS and Android, and integrating Copilot into popular platforms like Rakuten Viber in select regions. Notably, Copilot’s ability to tap into proprietary enterprise data while remaining compliant with corporate security policies gives it a long-term edge in regulated industries, where governance and data control are non-negotiable.

The Growing Rivalry: From Partnership to Competition​

When Microsoft invested over $13 billion in OpenAI, few could have predicted that their partnership would evolve into one of the tech sector’s most intriguing rivalries. Today, competitive tensions are coming to the fore. Microsoft is developing its own family of AI models and has hesitated to fully embrace OpenAI’s proposed structural changes. Simultaneously, OpenAI, keen to avoid over-reliance on Microsoft, has started inking agreements with rival cloud providers and acquiring startups that directly compete with Microsoft’s software portfolio—including Windsurf, a GitHub Copilot analogue.
Industry observers point to this dynamic as a classic case of “coopetition”—the blend of cooperation and competition that often defines tech alliances. For Microsoft, the short-term risk is clear: as employees snub Copilot in favor of ChatGPT, corporate IT strategies are undermined, and enterprise contracts remain vulnerable to renegotiation or churn.

Critical Analysis: A Tale of Two AI Assistants​

Strengths of ChatGPT​
