Semiconductor ETFs slid toward the $600 benchmark for the SMH fund as OpenAI concerns sparked a broader tech pullback. Investors across equity and derivative markets responded, pushing down tech‑heavy funds and amplifying the selloff. MarketWatch reported that big‑tech equities fell enough to weigh on the broader index, while Barron’s analysis highlighted a parallel drop in individual semiconductor stocks.

Yahoo Finance’s sector update confirmed the afternoon dip in technology shares, and Moomoo flagged the SMH price pressure as a test of the $600 level. The combined coverage points to heightened investor caution around AI‑driven revenue expectations. US chip manufacturers and investors holding semiconductor ETFs are the primary exposed parties.

Analysts noted that supply‑chain orders and capital‑expenditure plans could adjust if AI demand stabilizes. Further price action will depend on how quickly AI‑related sales rebound and on any regulatory signals affecting the AI ecosystem.
