U.S. stocks closed higher on Friday, extending Wall Street’s recent rally as investors continued to show strong confidence in companies benefiting from the artificial intelligence boom, while attention increasingly shifted toward the start of the corporate earnings season.

The major indexes all posted gains, helping the broader market secure its fourth weekly advance in the past five weeks despite ongoing concerns over geopolitical tensions, elevated interest rates, and questions about whether the rapid growth of artificial intelligence can continue to justify soaring company valuations.

The benchmark S&P 500 climbed 0.4% to finish at 7,575.39, while the Dow Jones Industrial Average added 149.60 points, or 0.3%, closing at 52,367.01. The technology-heavy Nasdaq Composite also advanced 0.3%, ending the session at 26,281.61 as technology shares continued to attract investor interest.

Technology companies once again dominated market sentiment, with artificial intelligence remaining the strongest driver of stock performance.

Among the day’s biggest stories was the Nasdaq debut of South Korean semiconductor giant SK Hynix.

The company, one of the world’s leading producers of advanced memory chips used in artificial intelligence systems, made a strong entrance into U.S. markets after raising approximately $26.5 billion through the sale of American depositary shares priced at $149 each.

Trading began around midday, and investor demand quickly pushed the shares sharply higher. By the closing bell, SK Hynix had surged 13.1%, reflecting continued enthusiasm for companies positioned at the center of the rapidly expanding AI industry.

The company’s remarkable performance follows an extraordinary year in its domestic market, where its Seoul-listed shares have climbed approximately 634% over the past twelve months.

The gains have been fueled by explosive demand for high-performance memory chips that power AI applications, cloud computing infrastructure, and advanced data centers.

The artificial intelligence revolution has generated enormous profits for leading semiconductor manufacturers as global technology companies continue investing billions of dollars in AI infrastructure.

However, the sector’s rapid rise has also sparked growing concerns among investors and analysts that valuations may be running ahead of business fundamentals.

Some market observers worry that the unprecedented spending on chips, servers, and massive data centers may ultimately fail to produce sufficient long-term productivity gains and corporate profits to justify current stock prices.

Those concerns have contributed to heightened volatility across AI-related stocks in recent months, with sharp swings becoming increasingly common as investors weigh long-term opportunities against valuation risks.

Despite those uncertainties, AI leaders continued to outperform on Friday.

Nvidia once again provided the strongest boost to the broader market after its shares climbed 4%, making it the single largest contributor to gains in the S&P 500.

The chipmaker remains one of Wall Street’s most influential companies as demand for its advanced graphics processors continues to surge across artificial intelligence applications worldwide.

Beyond the technology sector, investors are increasingly focusing on the upcoming corporate earnings season, which is expected to provide fresh insight into the health of the U.S. economy and the ability of major companies to sustain strong profit growth.

Airline giant Delta Air Lines was among the first major corporations to report quarterly results.

The carrier announced stronger-than-expected revenue and earnings for the April through June quarter, supported by resilient travel demand despite higher fuel costs. Delta said both leisure and business travel remained healthy during the period, allowing the company to offset increased operating expenses.

The airline also issued an optimistic earnings forecast for the summer quarter, with the midpoint of its guidance exceeding analysts’ expectations.

Despite the positive financial results, Delta shares declined 1.8% during Friday’s session. Analysts noted that the stock had already gained more than 28% this year, leaving investors inclined to lock in profits following the earnings announcement.

Wall Street’s attention is now turning toward next week’s earnings reports from several of the nation’s largest financial institutions, which are expected to provide an important assessment of economic conditions, consumer spending, loan demand, and corporate investment.

Among the major banks scheduled to report results are Bank of America, Citigroup, JPMorgan Chase, Goldman Sachs, and Wells Fargo.

Strong earnings from the banking sector could reinforce investor confidence that corporate America remains resilient despite higher borrowing costs and ongoing economic uncertainty.

Elsewhere in the market, Circle Internet Group gained 5% after announcing it had received regulatory approval in the United States to establish a national trust bank.

The company, which issues the USDC stablecoin, said the new institution will operate under the name Circle National Trust. Chief Executive Officer Jeremy Allaire described the approval as a significant milestone in integrating blockchain technology and digital assets more deeply into the U.S. financial system.

Consumer products manufacturer WD-40 also delivered one of the strongest performances of the day after reporting quarterly earnings that significantly exceeded analysts’ expectations. Investors responded positively to the results, sending the company’s shares up 10.6%.

Meanwhile, developments in global energy markets continued to influence investor sentiment.

Oil prices eased further after surging earlier in the week amid renewed geopolitical tensions involving Iran. Brent crude, the international benchmark for oil prices, slipped 0.4% to settle at $76.01 per barrel.

Although prices have moderated, Brent crude remains above the approximately $72 level recorded at the beginning of the week. However, it is still well below the wartime peak of nearly $120 per barrel reached during the height of earlier concerns over potential supply disruptions.

Energy markets remain focused on the Strait of Hormuz, one of the world’s most critical oil shipping routes.

Investors continue monitoring the possibility that renewed military conflict could disrupt tanker traffic through the strategic waterway, potentially restricting crude exports from the Persian Gulf and placing upward pressure on global energy prices.

Geopolitical uncertainty intensified after President Donald Trump announced on social media that the United States had agreed to continue diplomatic discussions with Iran while simultaneously declaring that the ceasefire between the two countries was over, adding another layer of uncertainty to already volatile markets.

The bond market also reflected investor caution.

The yield on the benchmark 10-year U.S. Treasury note edged higher to 4.56%, up from 4.54% at the previous close.

Higher Treasury yields have remained a challenge for global financial markets as investors continue to weigh the risk that elevated energy prices could keep inflation above central bank targets.

Persistent inflation may force the Federal Reserve and other major central banks to maintain higher interest rates for longer or potentially tighten monetary policy further if price pressures intensify.

While higher interest rates are designed to slow inflation, they also increase borrowing costs for businesses and consumers, potentially reducing economic growth and placing pressure on stock valuations.

International markets produced mixed performances to end the week.

South Korea’s Kospi index led major global markets with a gain of 2.5%, supported by continued strength in technology shares. Japan’s Nikkei 225 advanced 1.2%, reflecting optimism surrounding semiconductor and export-oriented companies.

In contrast, Chinese equities moved lower, with Shanghai’s benchmark index falling approximately 1% as investors weighed ongoing concerns surrounding economic growth and domestic demand.

Despite lingering uncertainties surrounding inflation, interest rates, energy markets, and geopolitical developments, Friday’s session demonstrated that investor enthusiasm for artificial intelligence remains one of the dominant forces driving global equity markets.

As corporate earnings season begins, investors will be closely watching whether strong financial results can continue to support record-high stock valuations and sustain Wall Street’s recent momentum.
