Cloud Stocks Retreat as AI Financing Worries Spread: Snowflake and Cloudflare Tumble 7%, Datadog Drops 6%

Cloud software stocks are under heavy pressure as worries about AI financing spread across the sector. High-growth names that posted strong recent results are absorbing much of the selling.

Snowflake (NYSE:SNOW | SNOW Price Prediction) stock is down 7% at $310.83 early in the session, leading the cloud group lower. Likewise, Cloudflare (NYSE:NET) stock is down 7% to $293.45. Meanwhile, Datadog (NASDAQ:DDOG) stock is down 6% to $249.08, representing a slightly smaller decline than its peers.

Sector funds are falling far less. The First Trust Cloud Computing ETF (NASDAQ:SKYY) is down 4%, while the Invesco QQQ Trust (NASDAQ:QQQ) is down 1.35%. In other words, large-cap tech is slipping but cloud-computing stocks are generally declining faster.

AI Financing Fears Hit High-Growth Cloud Names

This decline extends a rotation out of AI-linked stocks as investors question how AI infrastructure spending gets financed. Snowflake added its own wrinkle in late September, when it proposed a convertible note offering. Those notes can later convert into equity, placing Snowflake directly inside the financing debate.

Each company sells a different piece of the cloud: Snowflake offers a data platform, Cloudflare runs a global network for security and content delivery, and Datadog sells software that tracks applications and infrastructure. That mix ties revenue at all three to cloud usage, so an AI spending pullback could hit them at once (we featured seven suppliers supporting the AI expansion, from power to networking, in a free report you can grab here).

Strong Earnings Haven’t Shielded Snowflake

Snowflake’s latest results were strong. In its Q2 FY2027 report on September 2, Snowflake posted revenue of $1.55 billion, up 35.1% year over year, along with non-GAAP EPS of $0.62 that beat estimates.

Management also raised Snowflake’s fiscal 2027 product revenue guidance to $6.07 billion from $5.84 billion. Its net revenue retention held at 126%, and remaining performance obligations reached $9 billion. Those figures suggest customers are expanding their commitments to the platform.

AI adoption is adding to Snowflake’s momentum. CoCo passed 9,100 accounts in the quarter, while CoWork expanded to 5,800 accounts. Executives called AI a “powerful flywheel” for consumption.

One concern surfaced on Snowflake’s September earnings call. The company cut its fiscal 2027 non-GAAP product gross margin guidance to 74% because fast-growing AI workloads carry a lower contribution margin. Then-CEO Sridhar Ramaswamy stated “As models have gotten more powerful, cost has absolutely become a concern.”

Cloudflare Steers Clear of the AI Capex Race

Cloudflare has taken a more selective path on AI spending, even as it restructures around what it calls an “agentic AI-first operating model.” On its Q2 2026 earnings call in August, then-CEO Matthew Prince explained why Cloudflare avoids selling commodity compute:

I think not all revenue is created equal. And if you’re selling what is just commodity compute, if you’re basically letting, you know, an AI company use your balance sheet and your credit rating in order to buy servers that are the same as everybody else’s servers, that’s just not attractive business for us.

Prince added that Cloudflare has “always focused on how we can squeeze as much out of every CapEx dollar as possible.” That sets Cloudflare apart from hyperscalers that buy servers and lease them back.

Yet, that discipline hasn’t insulated Cloudflare stock. Datadog has leaned into AI with launches such as Bits AI and AI Guard, and Datadog shares are doing slightly better, though still trailing the cloud ETF.

Snowflake’s Financing Question Hangs Over Cloud Names

Snowflake’s bull case rests on demand for data platforms that feed AI workloads, backed by three straight quarters of accelerating product revenue growth. Cloudflare bulls point to its capital discipline, and Datadog bulls to AI monitoring demand. The bear case for all three: investors keep marking down AI-linked names until financing concerns ease.

The next test for Snowflake is whether AI demand keeps product revenue growth on its guided path. Traders may want to check for whether SKYY closes its gap with QQQ.

Strong recent results give Snowflake, Cloudflare, and Datadog a fundamental buffer, while the financing concern could keep the three stocks volatile. Position sizes should be kept small, if you choose to invest at all, until the AI financing question resolves.
