Natalia Connolly of the consulting firm AlixPartners says the AI tool Claude Code missed $800,000 in a single merger contract. BigGo Finance reported the claim on November 8, 2026. The short version: a tool that reads fast still overlooked a large sum in a deal document.
The players
Claude Code is an AI tool from Anthropic. It is built mainly to help people write software, not to review legal or financial paperwork. AlixPartners is a global consulting firm that advises companies on deals and turnarounds, which means helping them through big transactions or hard times. An M&A contract is the paperwork for a merger or acquisition, where one company buys or combines with another.
What is not known
The material available is thin, and the full article text was not available. It does not say what the $800,000 was, such as a fee, a payment term or a hidden cost. It does not say how the tool was used, whether the error was caught before anyone lost money, or how Connolly or AlixPartners responded. Those details would change how serious this is.
Why it matters
Many small businesses now use AI to summarize contracts, check invoices or flag risks. This story is a reminder that these tools can miss things, and a miss on the money terms can be costly. Having a person check the numbers before you sign or pay is a low-cost safeguard.
The takeawayIf AI helps you review a contract or invoice, have a person check the money terms before you sign or pay.
