Nasdaq market growth driven by AI and technology

The Nasdaq market has experienced significant growth driven by investments in artificial intelligence, semiconductors, and digital technologies. Early reports indicated a strong initial public offering market, with $111 billion raised in the first half of the year. This growth is supported by fintech developments, such as companies securing funding to integrate AI into regulated financial environments through secure intelligence layers and decisioning infrastructure. On September 22, 2026, the Nasdaq Composite reached a new record high of 27,231.59, marking its fourth consecutive positive session. This surge was primarily attributed to technology sector momentum, specifically regarding cloud computing growth, semiconductor demand, and AI infrastructure spending. While the Nasdaq saw significant gains, broader market performance was mixed; the Dow Jones Industrial Average declined by 0.4%, and the S&P 500 finished nearly flat. Notable gainers included Monolithic Power Systems, Western Digital, and Sandisk, reflecting strong demand for data storage solutions. By late September, both the Nasdaq Composite and Nasdaq 100 indices continued to close higher. The Nasdaq Composite rose 0.24 percent to finish at 26,861.06 points, while the Nasdaq 100 gained 0.23 percent to close at 30,408.50 points. Since the beginning of 2026, the Composite has risen 15.60 percent and the Nasdaq 100 has risen 20.64 percent. NVIDIA remains a central figure, recording the highest trading volumes across both indices. Analysts continue to monitor whether infrastructure spending is translating into durable revenue, noting that market breadth remains narrow as a small number of mega-cap companies drive most returns. At the start of the new quarter on September 30, US stock markets closed with moderate gains. The NASDAQ 100 rose approximately 0.31 percent, and the S&P 500 increased by 0.19 percent.
