What matters before the open

AI capex sustainability dominates the tape as TSMC's strong guidance clashes with hyperscaler ROI fears and open-source model commoditization. Netflix faces a 'show-me' quarter amid slowing engagement and Q3 guidance misses. Meanwhile, Korean memory makers see structural shortages despite ETF-driven liquidations.

Main narratives

day change
01

Hyperscaler capex sustainability faces open-source commoditization

TSMC's Q2 beat and raised capex guidance support the infrastructure buildout, but hyperscaler ROI is questioned as open-weight models (Kimi K3, DeepSeek) commoditize frontier AI, potentially capping hardware demand.

02

Engagement deceleration offsets peak bearishness

Netflix engagement growth slowed to 2% in H1 2026, and Q3 guidance missed estimates. Bulls argue the market is overly pessimistic, ignoring 12% revenue growth and live event strategy, while bears point to ad-tier scaling issues.

03

ETF liquidations mask structural DRAM deficits

Korean memory stocks suffered sharp declines attributed to retail ETF liquidations and margin peak fears. However, analysts project DRAM supply fulfillment dropping to 60% by 2027, with LTAs signed above spot rates.
