MU, SKHY Stocks Rise As Anthropic Filing Shows $450B In Compute Commitments; Kospi Rally Triggers Program-Trading Pause

What happened

Memory stocks rose after Anthropic's IPO filing showed first-half revenue of $16.3 billion and $450 billion in cloud computing commitments. Micron gained 1% overnight, SK Hynix 5.6% and Samsung 4% in Seoul, while the Kospi rose 3% and the Korea Exchange briefly paused program trading.

Confirmed

Global impact / market context

The $450 billion commitment is a signal of future spending on cloud and AI infrastructure, which supports demand for memory chips made by Micron, SK Hynix and Samsung. If that spending continues, it could lift revenue and capital spending across chipmakers and data-center suppliers, even though Anthropic itself reported large losses.

Analyst inference

Investors are looking past Anthropic's $80.7 billion net loss, driven by a $72.4 billion accounting charge on convertible notes, and focusing on its revenue growth and purchase commitments. That optimism lifted memory and neocloud stocks, while Nvidia, Intel, AMD, Amazon and Microsoft fell, showing money rotating into specific AI supply-chain names rather than broad tech.

Analyst inference

What to watch

1. The Korea Exchange triggered a sidecar, a brief pause in program trading that activates when futures move sharply. Watch whether another pause occurs if Seoul shares keep swinging during the session. Confirmed
2. Track how much of Anthropic's $450 billion cloud commitment flows to memory suppliers, since higher AI infrastructure orders would mean more revenue for Micron, SK Hynix and Samsung. Proposed
3. Watch whether Anthropic's large losses and convertible-note charge, which means debt that can turn into shares, raise doubts about funding future commitments and put pressure on memory and neocloud stocks. Analyst inference
