The United States stock market has achieved an all-time high as relentless enthusiasm surrounding artificial intelligence fuels a massive buying spree on Wall Street.

The benchmark S&P 500 stock index closed 0.58 percent higher on Tuesday, surpassing its previous peak set in mid-August. Meanwhile, the technology-heavy Nasdaq Composite also reached a record high, finishing up 0.45 percent. Technology shares dominated the top performers, with nearly all of the "Magnificent Seven" closing higher, excluding Meta.

Amazon led the gains with a 1.95 percent increase, followed by Microsoft up 0.78 percent and Tesla rising 0.51 percent. Both Apple and Alphabet gained 0.22 percent, while Nvidia rose 0.14 percent. Meta experienced a 0.41 percent decline, despite having risen over 20 percent since the launch of its new AI assistant, Muse, last month. Additional notable tech movers included Marvell Technology with a 5.81 percent increase and Cisco, which gained 4.54 percent.

Keith Lerner, chief investment officer and chief market strategist at Truist Advisory Services in Atlanta, Georgia, noted that the current market rally represents a clear technology and AI surge. "Every bull market has a dominant theme, and technology and AI remain this market’s dominant theme," Lerner told Al Jazeera, adding that technology and communication services were the only S&P 500 sectors to rise last month while the remaining nine declined.

Wall Street has successfully moved past various challenges facing the US economy, supported by hyperscalers’ massive multibillion-dollar investments in AI. Despite energy supply concerns resulting from the US-Israel war on Iran and a sell-off in US government bonds partly fueled by growing national debt, the market remains on course for its fourth consecutive year of double-digit returns. The S&P 500 has climbed 14 percent through 2026, and the Nasdaq Composite is up 18.78 percent.

"Investors remain bullish on the prospects for AI," Lochlan Halloway, a senior equity strategist at Morningstar Australia, told Al Jazeera. He explained that belief in strong returns from capital pouring into data centres has outweighed rising interest rates, expensive oil, and a 10-year bond yield exceeding 5 percent. While remaining positive on AI, Halloway cautioned that outcomes vary and market concentration in a handful of companies means the outlook for global and US shares depends on the ongoing success of the AI narrative.

Lerner suggested that historical trends and strong corporate earnings expectations could sustain the market rally through the end of 2026, though he acknowledged that rising interest rates present the primary risk to the upward trajectory. Meanwhile, Asian stock markets experienced declines on Wednesday morning, with major indexes in Japan, South Korea, and Hong Kong moving lower. Concurrently, oil prices increased as traders monitored ongoing conflict developments involving forces aligned with Yemen’s internationally recognised government and the Iran-aligned Houthis, with Brent crude futures reaching $101.45 a barrel.
