OpenAI suddenly faces a wave of legal problems. Many of them could spill over into the future of other large AI companies. That includes Microsoft (NASDAQ: MSFT | MSFT Price Prediction), Google (NASDAQ: GOOG), and Anthropic. Anthropic’s problem is its IPO valuation. For the two public companies, the problem is their share prices.

The OpenAI problem is anything but trivial. The FT describes the risk as “A spiraling legal crisis threatens to engulf OpenAI after its AI agents hacked dozens of companies and governments worldwide, with the prospect of a barrage of lawsuits marking the latest test of Sam Altman’s leadership.” The legal challenges run across risks from governments and companies. At the core is a rapidly rising number of hacks and the dollar value of the damages they may represent. The additional problem is that the hacks seem to be growing, and OpenAI has not announced a systematic program to slow them.

The legal problem is one of the questions at the heart of the AI sector. It joins several others that have been more prominent. The first is whether AI will destroy humanity. Employees at the companies and outsiders like Bill Gates have raised this, with Gates making a set of very public statements about AI’s disruptive potential.

On a more mundane level, customers have expressed anxiety about the cost of AI as a business tool. Recently, an open model from the company Reflection was described as powerful as those released by Chinese companies. Axios reports, “The marriage of an American open-weight model and Nvidia GPUs would give individuals and companies a new, cheaper alternative to Anthropic, OpenAI and Google.” Open models are usually free. Products from industry leaders are not. However, many customers say they do not need the firepower that Google, Anthropic, and OpenAI offer. They can build in-house applications that meet their needs.

Lawsuits are always a wildcard. The outcome of legal actions is hard to predict. Many lawyers and legal experts say, “A lawsuit is ultimately a journey into unpredictability.” The challenge OpenAI and its competitors face is not just whether they can win or lose lawsuits. It is also the sheer number they could face. Even if they won every case, the financial drain and drag on management time would be major challenges in themselves.

And then there is the question of how much hacking costs other companies. There has been a great deal of discussion about whether governments, or the industry itself, should put guardrails on new models while they are being tested for their ability to hack into systems, and how much damage they can cause.

Anthropic plans an IPO before Thanksgiving that could be worth a staggering $2 trillion. A flurry of lawsuits could challenge that valuation. Microsoft and Google’s future valuations depend heavily on the adoption of Copilot and Gemini. Google’s parent, Alphabet, is the world’s third-most valuable company, with a market cap of $4.16 trillion. Microsoft is fourth at $3.84 trillion. Alphabet’s valuation is no longer based on its Google search engine. Microsoft’s is no longer based on its Azure cloud business and its operating system.

Lawsuits are another major challenge to AI company valuations.
