Claude Suffers Global Outage a Day After Anthropic's IPO Filing

A Bad Day to Go Down

Anthropic's AI chatbot Claude experienced a global outage on Tuesday morning, suffering elevated errors across multiple services. The timing was striking: the disruption arrived just one day after the company announced it had confidentially filed for an initial public offering with the U.S. Securities and Exchange Commission. The outage primarily affected Claude's Opus 4.6 model, beginning at around 06:04 UTC and lasting several hours before a fix was implemented, with monitoring resuming at 10:42 UTC according to the company's status page.

A Pattern of Instability

This was not an isolated incident. The disruption follows a run of capacity-related issues that have troubled Anthropic's services in recent months. The company's status page shows incidents on a near-daily basis in the week preceding the outage, with elevated errors reported across models including Opus 4.7, Sonnet 4.6, and Haiku 4.5. Back in March, Claude went offline due to what Anthropic described as "unprecedented demand," knocking out consumer-facing platforms while the business API remained operational. The company has repeatedly cited "unexpected capacity limitations" as its user base grows rapidly.

IPO Filing and the Spotlight

The timing of Tuesday's outage drew particular scrutiny. On Monday, Anthropic confirmed it had submitted a confidential draft registration statement to the SEC, a key step towards a public listing that could value the company at close to $1 trillion. The filing reportedly puts Anthropic ahead of rival OpenAI in the race to go public. "This provides us with the opportunity to go public once the SEC finalises its assessment," the company said. The number of shares and the pricing have not yet been determined, and the offering will depend on market conditions.

What Investors Will Be Watching

The outage underscores the infrastructure challenges facing Anthropic as appetite for its models surges. With errors hitting its most powerful models almost daily through May and into June, the central question for prospective investors is whether the company can scale its infrastructure fast enough to match demand. During the March outage, Anthropic stressed that the API supporting businesses remained unaffected even as consumer platforms went down, a distinction that matters greatly to enterprise customers. As Anthropic moves towards a public listing, reliability is no longer just an engineering concern, it is a business and investor story.
