AI Edge Cloud Stocks Surge by 400 Billion Won in a Day

Fastly Inc. (NASDAQ: FSLY) closed at $25.10 on the Nasdaq on the 15th, up 7.36%, as over 10.5 million shares changed hands.
Its market capitalization swelled to about $3.8 billion (roughly KRW 5.3 trillion), adding nearly $300 million (KRW 420 billion) in a single day.
Since the start of the year, Fastly has stood out as a highly volatile tech stock, swinging sharply on expectations for AI-driven traffic and growing demand for edge computing.

Recently, projections that the sovereign cloud market will expand to $80 billion by 2026 have underscored potential tailwinds for the company, even as share-price volatility has picked up ahead of its next quarterly earnings report on May 6.

In March, Fastly switched its auditor to KPMG, sparking investor debate over its valuation and corporate-governance risks following the steep rally.

Headquartered in San Francisco, Fastly is an edge-cloud and content delivery network provider that delivers websites and applications quickly and securely around the world. Under CEO Kip Compton, who took the helm in 2025, the company has refocused on an AI- and security-centric edge platform, targeting $620 million in revenue for 2025 and aiming for further growth in 2026 while balancing profitability and expansion.
