The AI tools used most by companies. There's a surprising winner and a shocking laggard. (www.businessinsider.com)

A Wharton Human‑AI Research survey of business leaders, reported by Business Insider, finds that nearly 75% of companies are seeing positive ROI from generative‑AI projects and shows which vendor tools enterprises actually use. The headline: OpenAI’s ChatGPT is the most widely used, Microsoft’s Copilot outpaces Google’s offerings, and Anthropic’s Claude—despite expectations—is comparatively underused. Business Insider’s graphics illustrate these ranked adoption patterns and the author notes Copilot’s advantage likely stems from being embedded directly into Microsoft’s productivity stack. The result matters because it signals enterprise AI is moving beyond pilots to measurable value, and that distribution and integration matter as much as raw model quality. Technical implications include preference for tightly integrated assistants (Copilot) and widely accessible APIs/interfaces (ChatGPT), which lower deployment friction and accelerate ROI. The lagging adoption of Claude suggests market share still favors incumbents with strong enterprise channels, and it underscores ongoing priorities for companies: workflow embedding, security/compliance, fine‑tuning or private deployment options, and total cost of ownership. Vendors now face pressure to prove not just model performance but seamless enterprise integration, governance tooling, and measurable productivity gains.
