Anthropic is likely to name EY as its auditor, a decision shaped by conflicts among the Big Four accounting firms. The move highlights how AI partnerships are complicating regulatory compliance and IPO readiness.
Why EY Won the Mandate
The choice of EY comes down to a simple problem: the other three firms in the Big Four have too many entanglements. As Anthropic's business grows, its auditor needs to be independent, and that's getting harder to guarantee when the same firms are already working with other AI players and their investors.
EY, for its part, has been building out a technology practice that can handle the unique structure of AI companies. Anthropic's revenue model, its reliance on cloud partners, and its complex equity arrangements all need an auditor that understands the sector without tripping over a conflict.
The Conflict Problem at the Big Four
Conflicts among the Big Four aren't new, but they're sharper in AI. These firms audit and consult for a web of startups, venture funds, and hyperscalers. When one firm audits an AI company that has a strategic investment from a cloud provider, and that same firm also audits the cloud provider, independence gets murky.
Anthropic's situation is particularly tangled. The company has partnerships with major tech players, and those relationships create overlapping financial interests. The Big Four have to weigh whether they can serve Anthropic without compromising their work for other clients. In this case, the conflicts pushed the mandate to EY.
Choosing a Big Four auditor is a standard step for any company eyeing a public listing. For Anthropic, it's a signal that the company is getting serious about the regulatory and financial reporting requirements that come with an IPO.
The selection also reflects the broader trend of AI companies facing extra scrutiny. Regulators are paying close attention to how AI firms value their assets, account for partnerships, and disclose risks. An auditor with a clean slate and deep tech expertise is a practical necessity.
Anthropic hasn't confirmed the appointment, and EY hasn't commented. The official announcement could come with its next financial filing or ahead of a potential IPO filing. Until then, the market will be watching to see how the rest of the Big Four respond to the growing pile of AI-related conflicts.
