20% Surge in Two Days... Today, 7 Trillion Won Vanished from AI Infrastructure Stocks

On January 28, Cloudflare Inc. (NYSE: NET) shares plunged 10.3% on the New York Stock Exchange, closing at $184.73 on trading volume exceeding 5.52 million shares. Its market capitalization fell to about $58.2 billion (roughly ₩75 trillion), erasing nearly $5.4 billion (around ₩7 trillion) in a single day.

The downturn followed a two-day rally—each session up over 9%—driven by explosive interest in Moltbot, the company’s open-source autonomous AI agent built on Cloudflare’s infrastructure. Analysts attribute today’s sell-off to profit-taking after that surge. With the fourth-quarter 2025 earnings report set for February 10, investors are watching closely to see if the AI agent momentum will translate into higher revenue and improved profitability.

Cloudflare, a “connectivity cloud” provider combining web security, content delivery network (CDN), zero-trust networking and edge computing, has emerged as a go-to infrastructure partner for AI workloads thanks to its globally distributed network. High growth expectations and valuation have made its shares particularly volatile amid tech-sector rotation and profit-taking.
