Stock Market Recap — Sep 21, 2026
Nasdaq hits record with Meta-led AI rally
Falling oil prices set a risk-on tone, pulling yields lower and lifting futures before AI enthusiasm drove technology shares to a record close. Hawkish Fed rhetoric limited the rates relief, while oil partially rebounded after hours as hopes for US-Iran talks faded. • Markets/Oil: Nasdaq rose 2.3% to a record 27,122.09, while WTI settled 4.5% lower at $95.78. Brent later recovered to $101.06 as diplomatic optimism weakened. • Meta/AI: Meta surged more than 11% after Muse topped US app-store charts. Shopify agreed to integrate Muse with Shop Pay, while AMD, Intel and Arm rallied sharply. • Fed/Rates: Goolsbee warned that persistent demand-driven inflation could require a more aggressive response, and Musalem said additional rate increases would likely be needed. • Media M&A: Paramount settled challenges from 12 states and the Writers Guild, clearing the main state-level obstacle to its $110 billion Warner Bros. acquisition. • AI Infrastructure: Alibaba unveiled its Zhenwu V900 accelerator and targeted 20 gigawatts of cloud data-center capacity by 2032. Separately, financing concerns slowed SB Energy’s IPO plans despite additional Nvidia backing.
