Snowflake's AI Revenue Surge Masks Gross Margin Warning

What happened

Snowflake reported Q2 FY27 product revenue growth of 36% year-over-year, significantly exceeding expectations and prompting management to raise FY27 product revenue guidance to $6.07 billion. The strong top-line acceleration was driven by AI-related demand, but management simultaneously warned that expanding AI workloads are causing gross margin compression. Consequently, Snowflake lowered its FY27 non-GAAP product gross margin guidance to 74%, marking another 100 basis point reduction from previous estimates. This margin downgrade follows earlier concerns about stepped-up AI investment and discounting on large deals highlighted in Snowflake's FY26 disclosures. While the stock surged 20% pre-market on the revenue beat, the margin warning suggests that the cost of AI-driven growth is eroding profitability, a key factor in the prior WAIT rating.

Implication

Investors should closely monitor whether Snowflake can achieve operating leverage as AI workloads scale, or if gross margin remains structurally lower due to expensive infrastructure and cloud commitments; if margins do not recover, the investment thesis could weaken despite strong top-line growth.

Thesis delta

The Q2 FY27 results partially validate the AI-driven re-acceleration thesis, with revenue growth far exceeding the base case. However, the gross margin guidance cut indicates that the cost of this acceleration is higher than expected, pushing margins further below the level required for the bull case scenario. This lowers the probability of the bull case unless Snowflake demonstrates margin stabilization in subsequent quarters.
