European equity markets were set to open on a cautious note on Friday as global tech stocks came under renewed pressure amid mounting concerns about the sustainability of AI investments. Heightened fears of AI-driven disruption also weighed on sectors such as logistics, commercial real estate, and financials. On the macro front, investors will parse German wholesale price data, Spanish inflation figures, and a slate of Eurozone indicators including trade, employment, and GDP. Corporate earnings are due from Safran, NatWest, and Adyen, among others. In premarket trading, Euro Stoxx 50 and Stoxx 600 futures were flat to slightly higher, signaling a cautious start to the session.
