Live: Nvidia Hits $4 Trillion, Dow, S&P 500, Nasdaq Post Gains, Trump Issues Tariff Notices
Nvidia reaches a $4 trillion valuation, the highest ever recorded. Dow, S&P 500, and Nasdaq record modest gains. Trump sends new tariff notices to several countries with rates up to 30%. Follow live updates on markets and trade policy.

US markets saw modest gains on Wednesday, led by strong performance in the technology sector, as Nvidia reached an unprecedented $4 trillion market value. At the same time, renewed tariff threats from former President Donald Trump kept investors on alert.
The Dow Jones rose slightly by 0.1%, the S&P 500 added 0.2%, and the Nasdaq posted a 0.5% gain, supported by continued demand for tech shares.
Nvidia took the spotlight, setting a new all-time high in valuation. The company became the first in history to briefly touch a $4 trillion market cap, driven by ongoing enthusiasm around artificial intelligence and chip development.
However, positive sentiment was met with growing concerns over trade policy. Trump released a new round of tariff notices aimed at countries including Iraq, Algeria, Libya, and the Philippines. These new rates, ranging from 20% to 30%, follow previous warnings to other nations. Trump emphasized that all countries must finalize trade agreements by August 1 — a deadline he says will not be extended.

Copper Falls 3% After Hitting Record, Tariff Worries Weigh on Market
Copper prices dropped 3% on Wednesday, pulling back from record highs set just a day earlier. The dip comes as markets react to Trump’s plan to impose a 50% tariff on copper imports.
Import volumes had surged in recent weeks, with buyers rushing ahead of expected policy changes. The US relies on foreign sources for about half its copper supply. Any new duties would likely push up costs across key sectors, including power infrastructure, vehicle manufacturing, and data centers.

Starbucks Stock Rises on Reports of Potential China Partnership
Starbucks shares rose up to 2% early Wednesday following reports the company is exploring partnership options for its China business. According to CNBC, offers have come from firms like Centurium Capital, Hillhouse Capital, and Carlyle Group.
The coffee chain is aiming to keep a significant stake while finding a partner that aligns with its long-term strategy in the region. Starbucks has faced strong competition from low-cost rival Luckin Coffee, which operates more than double the store count in China.
Same-store sales in China had fallen sharply in late 2023 but have recently stabilized, helped by lower pricing and more demand for zero-sugar products. Analysts expect modest growth in the next quarter. Starbucks shares are up over 5% this year, slightly behind the S&P 500’s performance.
