US equity futures fell after a selloff in large tech names spilled into Asian AI-related shares, while investors awaited further progress in US‑Iran talks. Asia tech subindexes reversed an eight-day rally; Japanese and South Korean markets retreated and South Korean stocks dropped nearly 10%. Megacap tech moved in sync — Alphabet weakened and SpaceX slid as IPO enthusiasm cooled, notably for companies still cash‑flow negative yet reported to have raised about $75bn via an IPO. Market sentiment is shifting from last year’s broad AI euphoria toward a proof‑of‑performance phase, with investors demanding that heavy AI infrastructure investment produce returns. Market focus this week is Micron Technology’s earnings call. Gam Investment Management fund manager Jian Shi Cortesi said many investors holding AI names have large gains and may pare positions, and that tech is unusually sensitive to the interest‑rate outlook and potential Fed hikes.
