Nasdaq Futures Drop 0.7% as Broadcom Flags AI Financing Risks and CXMT Advances DRAM Design

US equity futures opened mixed on Tuesday with the Nasdaq lagging after Monday's low-volume session where the index fell 0.7%. Broadcom's warning on capital allocation risks and China's CXMT touting advanced DRAM architecture prompted sharp selling in Korean memory names, while Western Digital and Micron shares declined 4.5% and 2.8% in premarket. JPMorgan's FICC revenue miss of $5.37 billion against $6 billion estimates added to caution, though the bank raised its net interest income guidance.

The move reflects capital markets repricing the pace of AI infrastructure deployment. South Korean semiconductor firms absorbed the largest losses as CXMT's architecture progress signals faster Chinese catch-up in high-bandwidth memory, raising questions over long-term pricing power for established suppliers. Treasury yields declined 2-5 basis points as investors sought duration amid the rotation out of growth names, while the dollar index snapped a four-session advance.

State and corporate incentives remain aligned around securing compute capacity, yet the documented cost of capital and execution risk are now surfacing in price action. CXMT's advance and Broadcom's financing comment together indicate that supply constraints are easing faster than demand-side funding can scale, compressing margins for memory incumbents. Subsequent sessions will test whether the selloff broadens beyond hardware suppliers into software and cloud names dependent on sustained capex growth.

Federal Reserve speakers including Goolsbee and Barkin are scheduled today alongside existing home sales data, providing the next policy signal. Markets will watch whether the 10-year yield holding above 5.1% sustains pressure on valuation multiples or prompts a relief rally if data shows cooling labor demand.
