OpenAI ChatGPT and the Advertising Question

While Google and Anthropic celebrated product launches, OpenAI faced a different narrative. Code references such as “search ad,” “search ads carousel,” and “bazaar content” were discovered in ChatGPT Android app version 1.2025.329, suggesting the company is preparing to introduce advertisements.

Current Status:

  • No official announcement from OpenAI
  • ChatGPT has roughly 800 million people using it every week, up from 100 million weekly users in November 2023
  • India has become the single biggest user base, ahead of the US, with ChatGPT handling about 2.5 billion prompts a day

Potential Advertising Model: Evidence suggests that ads will start around search, shopping and recommendation answers, with marketplace-style product cards, not inside every normal chat. The approach would be similar to what Google shows in AI Overviews and what Microsoft's Copilot already displays for shopping queries.

CEO Perspective: Sam Altman acknowledged that ads are “something we may try at some point,” while emphasizing that ChatGPT's value comes from the trust users place in its recommendations. He noted that if ChatGPT were accepting payment to put inferior options above better ones, it would be catastrophic for user trust.

Strategic Context: The move appears driven by the need for additional revenue streams beyond subscriptions to support increasing computational demands and maintain free-tier access.

The November announcements demonstrate a market moving toward specialization. Rather than competing solely on general capabilities, companies are carving out distinct niches:

  • Google: Visual AI and creative workflows
  • Anthropic: Enterprise coding and precision tasks
  • OpenAI: Broad accessibility with potential ad-supported models

The Sustainability Question

According to the Wall Street Journal, Anthropic is positioned to break even by 2028, while OpenAI plans to hit that mark in 2030. This financial reality explains the different approaches to monetization and may presage further industry consolidation.

User Choice and Market Maturity

The competitive landscape now offers genuine choice based on use case rather than simply “which AI is best.” Professional developers can optimize for Opus 4.5's coding prowess, visual creators can leverage Gemini 3's image capabilities, and general users can choose between ChatGPT's accessibility and competitors' specialized offerings.

Conclusion: An Inflection Point for AI

November 2025 marks a defining moment in artificial intelligence competition. The simultaneous launches of Gemini 3 and Opus 4.5, contrasted with ChatGPT's advertising controversy, illustrate the industry's maturation from general-purpose tools to specialized, commercially viable products.

For users, the question is no longer “which AI should I use?” but rather “which AI best serves my specific needs?” Visual creators have a clear choice in Gemini 3's Nano Banana Pro. Developers and technical teams can leverage Opus 4.5's superior coding capabilities. General users must weigh ChatGPT's accessibility against potential advertising and the specialized strengths of competitors.

The meme that sparked this analysis may have been humorous, but it captures a genuine inflection point: the era of undifferentiated AI assistants is over, replaced by a diverse ecosystem where innovation, monetization, and user trust compete for primacy.

As these platforms continue to evolve, success will depend not just on technical capabilities but on aligning product strategy with user needs and sustainable business models. The companies that master this balance will define the next chapter of artificial intelligence.
