AI Infrastructure Stocks Surge 11 Trillion Won Ahead of Earnings

Cloudflare Inc. (NET) shares surged 9.74% on the New York Stock Exchange on May 5, closing at $246 and adding roughly $8.4 billion—about ₩11 trillion—to its market capitalization in a single day.

Trading volume topped 4.13 million shares, and its closing-market cap reached approximately $78.1 billion (around ₩110 trillion).

The rally is attributed to strong demand for AI infrastructure and security solutions, coupled with investor anticipation ahead of the company’s earnings report in two days.

With first-quarter results due on May 7, Cloudflare’s stock has climbed sharply, and alongside peers Fastly and DigitalOcean, it is being cited as a key beneficiary of AI-driven revenue growth.

Moreover, by expanding integration with the OpenAI Agent Cloud and forging partnerships with security firms such as Wiz and IBM, Cloudflare is deepening its footprint in AI applications and cloud security.

Headquartered in San Francisco, Cloudflare is a leading web security and content-delivery network provider that handles a significant portion of global web traffic and offers DDoS protection, DNS, and edge computing services.

Recently, the company has been building out edge-based AI inference infrastructure—leveraging Workers AI, AI Gateway, and a vector database—to position itself not merely as a CDN but as a core network platform for the AI era.
