Senate Shutdown Progress Buoys Hopes as AI Valuation Jitters Leave Markets Split

Investor focus turns to a pending House vote following the Senate’s advance on a temporary funding plan.

Overview

  • Wall Street closed higher Monday with a tech-led surge as Nvidia jumped 5.8% and Palantir gained 8.8% after the Senate advanced a measure to end the record U.S. government shutdown.
  • Trading turned mixed Tuesday as renewed concerns about rich AI valuations weighed on the Nasdaq, with Nvidia slipping after reports of a SoftBank share sale and CoreWeave’s guidance disappointment.
  • Mexico’s S&P/BMV IPC fell 0.45% on Monday but opened Tuesday at a new intraday high near 63,731 points, reflecting rapid swings tied to U.S. political and technology sector signals.
  • The Senate action still requires House approval to reopen federal operations, a key next step after more than 40 days without official U.S. data and with investors leaning on private indicators.
  • Operational strains persisted as the FAA ordered roughly a 4% cut to daily flights at 40 major U.S. airports and American Airlines reported over 250,000 weekend cancellations or delays, while Banxico’s governor signaled a possible December rate cut.
