U.S. stock markets closed mixed on Tuesday with the Nasdaq hitting a record high, driven by semiconductor gains as investors focused on AI hardware and memory chips like Micron and SanDisk. Oil prices declined for a fifth consecutive day after U.S.-Iran diplomatic talks, while upcoming Trump-Xi meetings on tariffs and trade will be the key catalyst this week for market direction.
U.S. stock markets closed mixed on Tuesday with the Nasdaq reaching a record high, driven by AI semiconductor strength—Micron and SanDisk surged on memory demand—while financials lagged amid fears of AI-driven fee compression. Oil declined to five-day lows amid U.S.-Iran diplomacy at the U.N., and upcoming Trump-Xi meetings on tariffs and AI represent the week's key catalyst for market direction.
Edgewater Research estimates Anthropic's 2027 DRAM demand could reach 40–50 billion 1Gb-equivalent units, potentially making the AI company a major DRAM buyer at Nvidia scale. About 20% of this demand could be purchased directly from memory manufacturers.
Micron is set to report Q4 earnings on Sept. 30, with investors closely watching commentary on 2028 market dynamics rather than near-term financials. The memory chip maker's high-bandwidth memory products are fully booked through 2027, making 2028 guidance critical to determining how long the AI-driven boom will sustain the current profitability cycle.
High-bandwidth memory (HBM) is consuming a disproportionate share of DRAM wafer production, creating structural supply constraints through 2027-2030. Samsung, SK Hynix, and Micron are allocating capacity primarily to AI data centers and servers, leaving consumer DRAM and NAND markets tight with elevated prices, while customers are securing multi-year supply contracts.
The Nasdaq reached a record high in a mixed market session Tuesday, with chip and AI stocks performing well while the Dow fell slightly due to losses in Cisco and financials. Crude oil prices continued declining, and Sandisk and Micron showed buy signals.
