The Fall of Character.AI: popularity that didn't pay for the servers
A platform with around 20 million monthly users was spending more on computing alone than it earned in its best month. For companies that build products on language models or buy them, this collapse shows where to look for risk.
From $2.7 billion to $20 million in two years
Character.AI is a platform for chatting with chatbots that imitate fictional characters, celebrities, and user-created personas. Last week, it filed for creditor protection in a Delaware court under Chapter 11 of the U.S. Bankruptcy Code. Foreign media report the date as October 12 or 13. The company's liabilities are estimated at $50-100 million, with assets at a similar amount.
In August 2024, Google paid $2.7 billion for a non-exclusive license to Character.AI's technology. In practice, it bought back the founders, Noam Shazeer and Daniel de Freitas, along with part of the research team. Today, Disney is offering $20 million for selected, undisclosed assets and a non-exclusive license to part of the intellectual property. It is acting as the stalking horse bidder, meaning the bidder setting the opening price for the auction, so someone else could still outbid it.
The sale is expected to close at the end of November or the beginning of December. Until then, the service and paid subscriptions remain active. If no suitable offer appears, the platform will be shut down.
More than the asset price, the numbers about people are telling. According to a court document obtained by Bloomberg, Disney agreed to make job offers to at least 60 employees, that is, most of the team, with total annual compensation estimated at $60 million. The vast majority accepted. On salaries alone, Disney will therefore spend three times more per year than it is offering for the assets. The conglomerate's first CTO is already Karandeep Anand, former president of Character.AI. The same Disney had previously accused the platform of using characters from its franchises without permission and sent it a cease-and-desist letter.
A balance sheet that was never going to add up
Character.AI did not fail for lack of interest. The company reports around 20 million monthly active users, and at its peak, in mid-2024, around 28 million. Other sources cite 12 to 21.6 million, depending on the metric, so these figures should be treated with caution. The problem was elsewhere. Court documents described by 404 Media show the following breakdown:
- computing: $13.8 million per month in 2024 and $10 million in 2025,
- January-August 2026: $56.1 million for computing and $19.7 million for salaries,
- subscriptions: at most $2.8 million per month, at times below $1 million,
- all revenue, including ads: $5.3 million in the best month,
- loss in August 2026: about $8-9 million per month.
Our calculation: this year, computing alone cost an average of about $7 million per month. That is more than the company earned from all sources in its best month. With 20 million users and no more than $2.8 million from subscriptions, that works out to just a few cents of revenue per user per month. Meanwhile, every chatbot conversation costs money, because the model has to be run each time.
CEO Colin Adams admitted in a statement filed in court that the company's technology is expensive to maintain and that profitability had been a problem since the beginning of operations. In the filing, the company juxtaposes a "large and engaged user base" with high costs, the risk of legal claims, and regulatory proceedings. Lawsuits from families, including the mother of a 14-year-old boy who took his own life after an obsessive relationship with the platform's chatbot, a lawsuit by the state of Kentucky, and investigations into child safety added expenses. However, the documents show that the company was also not profitable regardless of these disputes.
Why an AI product doesn't add up like ordinary SaaS
Classic SaaS (software delivered by subscription through a browser) achieves margins in the 80-90 percent range, because serving one more customer costs almost nothing. Industry estimates for AI services speak of 50-60 percent. Inworld AI, a company in the conversational AI industry and therefore a non-neutral source, calculates the daily AI cost per active user at from $0.09 for text chat on a small open model to $18.24 for a voice conversation on OpenAI's flagship model. When about 3 percent of users pay, one subscriber has to cover the costs of about 33 people.
Character.AI did what is usually advised. It simplified its models and moved part of the workload to cheaper infrastructure. It abandoned building its own foundation models in favor of fine-tuning models with open weights. It laid off people, introduced ads in mid-2025, and paid add-on features at the beginning of 2026. Computing costs fell by roughly half, but the loss still amounted to millions of dollars per month.
This is where a caveat to a popular piece of advice comes in handy. Lightning AI, a provider of tools for building models, argued in Business Insider Polska that greater savings than hunting for cheaper tokens (query billing units) come from building smaller models tailored to a company's data and tasks. The advice sounds reasonable, but it is worth remembering that its author profits from it. The Character.AI case shows the limit of that advice: a cheaper model lowers the bill, but it will not fix a product that brings in just a few cents in subscription revenue per user.
What happens to data when the provider disappears
Disney's offer does not include user data or chat histories. They may be sold separately, to another buyer. The company says its data protection practices have not changed, but its privacy policy since August 2025 allows data to be transferred in an asset sale. This includes private conversations, including voice conversations, mental health information, age, and device identifiers.
A coalition of 40 U.S. state attorneys general filed objections in the proceedings and is demanding nine binding conditions for any buyer. These include age verification, deadlines for deleting data, and limiting the training of models on private conversations without explicit consent. New York Attorney General Letitia James noted that the company collected some of the most private thoughts children have ever shared, and now those conversations may go to the highest bidder. The point of reference is the 23andMe case from 2025: the U.S. Federal Trade Commission then found that privacy promises are also binding on the buyer of assets from bankruptcy.
Questions to ask before signing with an AI provider
For companies that build products on language models or buy them from start-ups, this story leads to a checklist of questions:
In the end, the lesson is simple: the popularity of an AI product proves nothing until revenue per user exceeds the cost of serving that user. It is worth doing that math before signing the contract, not in bankruptcy court.
