Chip Selloff Goes Global: SK Hynix, Samsung, and SoftBank Join the $1 Trillion-Plus Rout

The semiconductor selloff stopped being an American story this week. SK Hynix, Samsung, and SoftBank led a rout across Asian tech, as chip stocks worldwide shed more than $1 trillion in a decline that has now touched every link of the AI supply chain — memory, foundry, equipment, and the holding companies financing it all.

The globalization of the selloff matters because of what it rules out. A US-only decline could be blamed on rotation or domestic politics. A synchronized slide through Seoul and Tokyo says the market is repricing the AI capex cycle itself — the shared revenue stream every one of these companies depends on.

The dominoes so far

The sequence began with Intel's foundry troubles — reports that its 18A-P node would not hit profitable yields until late 2026 or 2027 — then compounded through Meta's plan to resell surplus AI capacity and DeepSeek's move toward in-house silicon. Each development attacked a different pillar of the bull case: execution, scarcity, and customer lock-in respectively.

Memory makers are exposed to the same math from a different angle: high-bandwidth memory expansions were financed against demand projections that suddenly carry error bars. SoftBank, with its leveraged, concentrated AI bets, trades as the sector's high-beta proxy — and traded like it this week.

Where it stabilizes

The bulls' case is that this is a violent mid-cycle correction in a secular trend — that inference demand keeps compounding regardless of whose training capex plateaus, and that July's forced selling created the entry the fast money spent two years waiting for.

The bears' case is simpler: the SOX is finishing its worst month since 2008 because the marginal buyer of compute just became a seller. Both cases will be argued through earnings season. What is no longer arguable is the one-way market — that ended in July, on volume, in every time zone.
