Snowflake (SNOW) stock tumbled after the AI data cloud provider reported a narrower-than-expected loss but issued guidance that fell short of the Street’s estimates. The company also announced it expanded its partnership with Anthropic (ANTH.PVT).

Snowflake shares fell 8% in pre-market trading on Thursday.

The Montana-based company reported on Wednesday that revenue grew 29% year over year to $1.15 billion during the quarter, slightly missing Wall Street’s estimates of $1.18 billion, according to S&P Global Market Intelligence. Snowflake reported a net loss per share of $0.87, a smaller loss than the $0.96 per share analysts were expecting.

For the fourth quarter, Snowflake guided for product revenue between $1.19 billion and $1.2 billion, which was slightly below the midpoint revenue forecast by the Street of $1.23 billion. The full-year revenue guidance of $4.44 billion also fell below expectations of $4.6 billion.

Snowflake also announced a multiyear, $200 million agreement with Anthropic that will make Anthropic’s Claude AI models available on the Snowflake platform and establish a joint venture to deploy AI agents across the world’s largest enterprises.

The deal deepens Snowflake’s relationship with Anthropic, as the company has already processed trillions of Claude tokens on its platform.

“Enterprises have spent years building secure, trusted data environments, and now they want AI that can work within those environments without compromise,” Anthropic CEO and co-founder Dario Amodei said in a statement. “This partnership brings Claude directly into Snowflake, where that data already lives. It’s a meaningful step toward making frontier AI genuinely useful for businesses.”
