Stocks Ease After Shutdown Rally as AI Hype and Market Optimism Collide

​Market Pauses After a Hot Start
Wall Street’s early-week euphoria cooled Tuesday, with U.S. stock futures dipping after a strong rally sparked by hopes that Washington may finally end the record-breaking government shutdown.

The S&P 500 edged down 0.2%, the Dow Jones Industrial Average hovered flat, and the Nasdaq 100 slipped 0.4%, showing traders are catching their breath after a tech-fueled surge that kicked off the week.

Investors are balancing optimism about a potential shutdown resolution with renewed caution over the AI sector, where growth hopes remain sky-high — but increasingly fragile.

CoreWeave Pullback Tests AI Faith
AI infrastructure provider CoreWeave cast a shadow over the tech rally after trimming its full-year revenue forecast, despite strong quarterly results. The Nvidia-backed company said one of its data center partners delayed deployment, sending its stock down more than 8% in premarket trading.

Meanwhile, SoftBank made a surprise move — selling its entire $5.8 billion stake in Nvidia to fund its next wave of AI investments. Founder Masayoshi Son said the sale would free up capital for new ventures, including partnerships with OpenAI and Oracle, as he seeks to build his own global AI ecosystem.

Despite the shake-up, Nvidia’s stock rose 5.8% Monday and held near $196 premarket, as investors viewed SoftBank’s sale as a strategic reshuffle rather than a loss of confidence.

Shutdown Vote Sparks Hope — but Not Complacency
Markets were also buoyed by signs that the 41-day U.S. government shutdown may soon end. The Senate passed a funding bill Monday night, sending it to the House of Representatives for a final vote.

President Donald Trump expressed support for the measure, even though it omitted the healthcare subsidy extensions Democrats had demanded. Lawmakers are expected to hold a separate vote on those Affordable Care Act credits in December.

Investors welcomed the progress, though many remain cautious about how quickly federal operations can restart and whether a new round of political wrangling could emerge before year-end.

TSMC Adds a Note of Caution
Adding to the day’s mixed tone, Taiwan Semiconductor Manufacturing Company (TSMC) reported its slowest monthly revenue growth in more than a year, underscoring concerns that the AI chip boom might be outrunning real-world demand.

Sales rose 16.9% in October, just shy of forecasts — a slowdown compared to earlier months. Analysts noted the figures were distorted by early order pull-ins and a stronger Taiwanese dollar, but the data still fueled talk that AI chip demand could be plateauing after a year of extraordinary gains.

The Takeaway: Euphoria Meets Exhaustion
Tuesday’s session marks a reality check for markets that have sprinted ahead on AI optimism and shutdown relief. The AI trade remains dominant, but the latest updates from CoreWeave, SoftBank, and TSMC highlight that even this juggernaut isn’t immune to pressure.

As one strategist put it, “This isn’t the end of the AI story — just a reminder that it’s not all straight lines up.”

​For now, traders are watching Washington, waiting for the shutdown to end — and wondering whether the next rally still has fuel left in the tank.
