Snowflake shares exploded 23% on Wednesday, closing at $359.14 and touching a new 52-week high, after the cloud data platform posted a fiscal second-quarter beat so strong that even skeptical analysts scrambled to raise their targets. The move ranked among the single biggest one-day stock gains on Wall Street this week, and it wasn't a fluke — trading carried into Thursday's session as investors digested a guidance hike that few had expected.

The numbers told the story. Snowflake reported adjusted earnings of $0.62 a share against a Wall Street consensus of just $0.45 — a beat of nearly 38% — on revenue of $1.55 billion, ahead of the $1.48 billion analysts had modeled, according to an earnings call transcript published by Investing.com. Product revenue, the metric Wall Street watches most closely for Snowflake's consumption-based business, rose 37% year-over-year to $1.49 billion — the company's third straight quarter of accelerating growth.

AI tools do the heavy lifting

Management credited artificial intelligence products — including the Cortex platform, the CoCo coding agent and the CoWork tool — with driving nearly half of that acceleration. CoCo alone has amassed more than 9,100 paying accounts, up over 2,000 in a single quarter, while net revenue retention held at 126% and the company added 692 net new customers, up 32% from a year earlier, per Investing.com's earnings breakdown.

"AI is compounding Snowflake's advantage across three reinforcing dynamics," said CEO Sridhar Ramaswamy, pointing to new workloads, faster product adoption and rising platform consumption.

Snowflake didn't just beat the quarter — it raised the bar for the rest of the year. Full-year product revenue guidance jumped to $6.07 billion from $5.84 billion, implying 36% growth, while non-GAAP operating margin guidance climbed to 14.5% from 13.5%. Remaining performance obligations, a proxy for future bookings, hit $9 billion, up 30% year-over-year, according to 24/7 Wall St.'s market wrap, which also noted knock-on gains for cloud peers Oracle and Cloudflare on the same day.

Wall Street's response was swift. Needham lifted its price target to $450, and multiple other desks reiterated bullish ratings, though not everyone is celebrating unreservedly — Guggenheim held a Neutral rating, and Investing.com's own analysis flagged that the stock is now up roughly 68% year-to-date, raising the question of whether the AI-fueled rally has already priced in the good news.

The stock's after-hours pop was a reversal in itself: shares had actually slipped more than 4% during Wednesday's regular session before the results dropped, only to erase that loss and then some once the report hit. Snowflake's next test comes with third-quarter guidance already on the table — $1.588 billion to $1.593 billion in product revenue, implying 37-38% growth — a bar the company will need to clear again to keep momentum, and the stock, moving in one direction.
