ChatGPT’s Third Anniversary: What It Means for the Industry

ChatGPT celebrated its third anniversary on November 30, marking three years since OpenAI released the chatbot that became the fastest-growing consumer application in history and catalyzed the current AI boom.

When OpenAI introduced ChatGPT on November 30, 2022, the company described it simply as “a model called ChatGPT which interacts in a conversational way.” Within two months, the application reached 100 million users—a growth rate that shattered previous records. Today, ChatGPT serves 800 million weekly users, roughly double the combined user base of its five main competitors.

The adoption numbers continue climbing. About one-third of American adults have used ChatGPT, with that figure rising to nearly 60% among adults under 30, according to Pew Research Center. The application remains the top-ranked free app on Apple’s App Store.

From Startup to $500 Billion Valuation

The commercial transformation has been equally dramatic. Eighteen months before ChatGPT’s release, OpenAI held a $14 billion valuation. The company is now valued at $500 billion, placing it among the 20 most valuable companies globally.

The ripple effects have reshaped technology markets. Nvidia’s stock has gained 979% since ChatGPT’s launch, as demand for AI training chips exploded. The seven most valuable S&P 500 companies—Nvidia, Microsoft, Apple, Alphabet, Amazon, Meta, and Broadcom—all have significant AI exposure, contributing to a 74% surge in the broader index.

Microsoft’s partnership with OpenAI has positioned the company as a leader in enterprise AI. Google responded by accelerating its own AI assistant development, while Meta, Amazon, and Apple have all expanded AI initiatives.

The funding environment reflects sustained investor enthusiasm. Recent AI funding rounds have reached into the billions, with infrastructure companies, application developers, and specialized AI startups all attracting capital.

Three Years of Fast Evolution

ChatGPT itself has evolved substantially. The original release used GPT-3.5; OpenAI has since launched GPT-4, GPT-4 Turbo, and most recently GPT-5 with expanded reasoning capabilities. The product has expanded from text chat to include image generation, voice interaction, web browsing, and code execution.

Competition has intensified with Anthropic’s Claude, Google’s Gemini, and open-source alternatives like Meta’s Llama gaining market share. Yet ChatGPT’s first-mover advantage and brand recognition have proven durable.

The three-year milestone arrives at a transition point for the AI industry. Initial hype cycles have given way to questions about practical applications, enterprise deployment, and return on investment. OpenAI itself has shifted from a nonprofit research lab to a capped-profit company now pursuing a full for-profit conversion.

For workers across industries, ChatGPT’s anniversary carries mixed implications. Productivity tools have proliferated, but so have concerns about job displacement and the devaluation of certain skills. The past three years have established that AI will reshape work; the next three will likely determine how comprehensively.

ChatGPT didn’t invent large language models, but it made them accessible to hundreds of millions of people who had never interacted with AI directly. That distribution achievement—turning research into a consumer product used by a third of American adults—may prove to be OpenAI’s most consequential contribution, regardless of what technical advances follow.
