Sam Altman spent years calling advertising a last resort. "If we need to make money that way, we will. But it feels like a failure," he said in 2023.
On February 9, 2026, ChatGPT started running ads. Six weeks later the pilot had crossed $100 million in annualized revenue. By May 5, any US business could buy a placement directly at ads.openai.com with no minimum spend.
The same week, Klarna — the company that became the poster child for AI replacing human workers — quietly started rehiring the people it fired. CEO Sebastian Siemiatkowski said publicly: "We went too far."
Two of the most cited AI success stories reversed course in the same week. Almost nobody is asking the right question about what it means for you.
What OpenAI just built and why it changes your acquisition strategy
Here is what ChatGPT ads actually are, and why the targeting is unlike anything that has existed before.
Google infers what you want from your search history. Meta infers it from your behavior. ChatGPT users directly state exactly what they want, in natural language, in real time. When someone types "what is the best project management tool for a 10-person remote team?" - they are not browsing. They are deciding.

What changed on May 5
OpenAI removed the minimum spend entirely. At launch it was $200,000. By April it dropped to $50,000. On May 5 it went to zero. CPC floor is $3–5. CPM is $25, down from $60 at launch. The channel is open. Any US founder can now buy placements inside ChatGPT conversations for any budget.
The minimum spend dropped from $200,000 to zero in 90 days. That is not a pricing decision. That is a land-grab. OpenAI wants as many advertisers inside the platform as possible before the CPMs normalize and the channel becomes crowded.
Early Criteo data from the pilot shows LLM referrals convert at 1.5x compared to other digital channels. The window where ChatGPT ads are cheap, uncrowded, and high-converting is open right now. It will not stay open.
The most important technology product of the decade just became an ad platform. Your customers are already inside it. The question is whether your competitor will be the sponsored answer they see.

The Klarna story nobody told correctly
In 2023, Klarna CEO Sebastian Siemiatkowski called Sam Altman and told him he wanted Klarna to be OpenAI's favorite guinea pig. The company replaced 700 customer service agents with an AI chatbot. In earnings calls and press releases, Klarna claimed the AI was handling two-thirds of all customer interactions.
The efficiency gains were real. The cost savings were real. The story was everywhere. Then something quieter happened.
2024 - The announcement
Klarna claimed AI handles ⅔ of all customer interactions. Story covered globally as proof AI could replace human workers.
700 Jobs replaced by AI chatbot
2026 - The reversal
CEO: "We went too far. We focused too much on efficiency and cost. The result was lower quality."
Rehiring human agents being recruited again
Customer satisfaction on complex interactions dropped. The cost savings did not fully materialize once you accounted for the cases the AI could not handle. By September 2025, Klarna was reassigning internal staff back to customer support. By February 2026, the CEO said it publicly.
Klarna is now recruiting human agents again - specifically targeting students and rural workers - and framing the reversal as a strategic evolution. External analysts were more direct.

The IBM data point nobody quotes
Only 1 in 4 AI projects delivers the return it promises, per IBM research. The Klarna case is now what analysts call the canonical enterprise cautionary tale of 2026. Every executive proposing an AI workforce strategy gets asked the same question: how does your plan avoid the Klarna outcome?
The real lesson is not that AI failed at customer service. It is that full replacement failed. Augmentation works. Replacement does not.
What these two stories mean for your business right now
Taken together, OpenAI's ad launch and Klarna's reversal are telling you the same thing from opposite directions. One is about distribution. One is about operations. Both are about the gap between what AI can do in theory and what actually works in practice.
1. Check what ChatGPT says about your category today.
Open ChatGPT and type: "what is the best [your product category] for [your use case]?" That answer is your new competitive landscape. 900 million weekly users are asking questions like this right now. Do you appear? Does your competitor? If you don't know, you are flying blind on your most important emerging acquisition channel.
2. Audit where you are using AI for full replacement vs augmentation.
Klarna replaced humans entirely. The hybrid model - AI for volume, humans for complexity - consistently outperforms full automation on both cost and satisfaction metrics. Map every AI-powered function in your business and ask: what breaks if you remove the human entirely?
3. Decide if your acquisition strategy is built for 2019 or 2026.
If your entire customer acquisition depends on Google search, you are one algorithm shift away from a crisis. ChatGPT ads are currently cheap, uncrowded, and converting at 1.5x vs other channels. The window where early movers get cheap clicks is open now. Model what $5,000/month in ChatGPT ad spend would do for your business before the CPMs normalize.

🔮 The Bottom Line
ClaSam Altman called advertising a failure state. Then he built a $100 million ad business in six weeks.
Sebastian Siemiatkowski called AI the future of customer service. Then he rehired the people he fired.
Neither story is about hypocrisy. Both are about the same thing: the gap between what AI can do in theory and what actually works in practice is still being discovered in real time at enormous scale, with real consequences for every founder watching.
You are not too small to be affected by either. You are exactly the right size to move faster than the companies making these mistakes.
