A New York Times report that OpenAI may delay its IPO triggered a fifth straight Nasdaq drop and a brutal semicap selloff — FormFactor −12.1%, Micron −6.7% — while capital rotated into software, lifting Microsoft +5.7%.

Microsoft (MSFT) was the basket's clear leader, up 5.7% to $372.97, one session after touching its deepest drawdown of the year. The proximate spark was a disclosure that Michael Burry had taken long-dated MSFT call options expiring December 2028, but the structural driver was a rotation out of AI accelerators and capex names into AI software leaders — the hyperscalers that monetize the buildout rather than fund it. Microsoft sits on the accelerators-capex chokepoint as a demand anchor: its record fiscal-Q3 (Azure +40%, AI ARR past a $37B run-rate) makes it the cleanest large-cap proxy for whether AI compute spend is converting to software revenue. Amazon (+2.5%) and Meta (+1.4%) rode the same rotation; the silicon they buy did not.

FormFactor (FORM) was the worst name in the basket, down 12.1% to $130.74, the sharpest casualty of a semiconductor-equipment rout that hit the entire toolchain. The trigger was a New York Times report that OpenAI is weighing delaying its IPO into 2027 — citing SpaceX's weak post-debut performance and AI-share volatility — which reignited fears about the durability of AI capex and sent the Nasdaq down 0.24% to 25,297.62, its fifth straight loss (the index fell 4.6% on the week). FORM maps to the HBM-memory chokepoint via the probe cards that test stacked memory; it sold off alongside Camtek (CAMT −8.5%), Onto Innovation (ONTO −5.9%), Entegris (ENTG −8.4%), Amkor (AMKR −8.1%), Applied Materials (AMAT −6.2%) and Lam Research (LRCX −5.7%).

The damage radiated across every compute chokepoint except the hyperscalers. Memory gave back Thursday's euphoria: Micron (MU −6.7% to $1,132.33) sold the news of its own record HBM4 quarter. Optical interconnect was crushed — Credo (CRDO −11.2%), Fabrinet (FN −7.6%), Coherent (COHR −6.6%), Marvell (MRVL −5.2%). Cooling and power, the physical chokepoints, fell hard too: Modine (MOD −9.8%), Vertiv (VRT −6.6%), Eaton (ETN −4.1%), GE Vernova (GEV −3.7%). The accelerator complex was comparatively orderly — NVIDIA (−1.6%), AMD (−2.1%), Broadcom (−3.7%), ASML (−2.5%), TSMC (−0.6%) — confirming the move was a rotation within AI, not a wholesale exit.

The calendar is dense and the IPO headline cuts directly into it. Commerce's Section 232 data-center-semiconductor report to the President is due around July 1, and PJM's 2028/2029 Base Residual Auction closes July 7 — a direct read on the data-center power premium. The earnings wave opens with ASML (July 15) and TSMC (July 16), then Samsung (July 23) and SK hynix (July 29) for the next HBM read. Furthest out, OpenAI's own listing window — the Q4 2026 target the Friday report cast into doubt — now hangs over the whole accelerators-capex chokepoint.
