Microsoft shares climbed roughly 3.3% on May 28, adding to a broader software sector rally. The catalyst was not Microsoft itself, but Snowflake, whose fiscal Q1 results suggested that enterprise AI demand is translating into real revenue.
Snowflake’s stock surged 36% on the day, its best trading session ever, after reporting product revenue of $1.33 billion, a 34% jump year-over-year. The company raised its full-year guidance, and the ripple effect was immediate. Palo Alto Networks, Atlassian, and Microsoft all rode the wave higher.
Why Snowflake’s earnings moved the entire sector
Microsoft and its peers had fallen 10-14% year-to-date before this rally, largely because investors were spooked by the enormous capital expenditures required to build out AI infrastructure. The fear was that companies were spending billions on AI without a clear path to monetizing it.
Snowflake’s earnings flipped that narrative. A 34% revenue growth rate, combined with raised guidance, told Wall Street that enterprise customers are not just experimenting with AI — they are paying for it.
