Snowflake (SNOW) Surges 37% After-Hours on $6B AWS Deal and Raised Full-Year Forecast

Snowflake Inc. shares surged 37% in extended trading on May 27, 2026, after the data cloud company announced a $6 billion multi-year expansion of its partnership with Amazon Web Services and raised its full-year revenue outlook. The expanded agreement includes Snowflake’s commitment to spend an additional $6 billion on AWS services and use Amazon’s in-house Graviton chips. The deal also deepens collaboration on generative and agentic AI product integration. The news, combined with a beat-and-raise quarterly report, fueled the after-hours rally. Shares had closed down about 20% year-to-date at $175.26 before the spike. For the fiscal first quarter ended April 30, Snowflake reported revenue of $1.39 billion, a 33% year-over-year increase, and adjusted earnings per share of $0.39, both well above analyst estimates of $1.32 billion and $0.32. Product revenue, roughly 95% of total sales, rose 34% to $1.33 billion. The company forecast second-quarter product revenue between $1.415 billion and $1.42 billion, above the $1.37 billion consensus. Full-year product revenue guidance was lifted to $5.84 billion, exceeding its prior view and Street estimates.
