Nasdaq Reaches a New Intraday Record

Global financial markets received a fresh boost from renewed enthusiasm surrounding artificial intelligence, with the Nasdaq Composite reaching an intraday record of 27,231.59 on September 22, 2026.

The index gained 0.40% during the session as investors continued to focus on strong technology earnings and expectations for continued investment in artificial intelligence.

The move reflects renewed interest in technology stocks after a period of market uncertainty surrounding inflation, interest rates and geopolitical risks.

AI Optimism Supports Technology Stocks

Artificial intelligence has once again become a major driver of market sentiment.

Recent developments surrounding AI products and infrastructure have encouraged investors to reassess the growth potential of technology companies. Reuters reported that optimism around AI adoption and corporate earnings helped support the Nasdaq’s latest advance.

The enthusiasm has also extended to semiconductor companies, which are closely linked to demand for AI computing infrastructure.

Earlier in the week, AMD reached a market capitalization of $1 trillion after its shares gained around 10%. Intel and Arm also recorded significant gains as semiconductor stocks attracted renewed attention.

Oil Prices Move Lower

While technology stocks strengthened, oil prices moved in the opposite direction.

U.S. crude fell 0.47% to around $95.33 per barrel, while Brent crude declined 0.43% to approximately $99.92 per barrel on September 22. Reuters attributed the move partly to improving expectations for oil supply from the Middle East.

Lower oil prices can influence inflation expectations because energy costs affect transportation, manufacturing and consumer prices.

Markets therefore continue to monitor developments in energy markets alongside monetary policy and geopolitical events.

Global Markets Also Gain

The positive sentiment was not limited to the United States.

The MSCI World Index edged up 0.08%, while Europe’s STOXX 600 gained 0.2% during the same trading session. Technology-related optimism helped support broader market sentiment.

Investors are also watching international developments, including U.S.-China relations and potential discussions involving artificial intelligence cooperation.

Investors Watch AI Spending and Interest Rates

Despite the latest market gains, financial markets remain sensitive to interest rates.

The Federal Reserve recently raised its benchmark rate to 3.75%-4.00% and indicated that another increase could be possible later in 2026. That creates a contrasting backdrop for technology stocks because higher borrowing costs can affect corporate investment and company valuations.

For now, strong expectations surrounding AI spending and technology earnings are helping support market sentiment. However, investors continue to monitor inflation, interest rates, oil prices and geopolitical developments as potential sources of market volatility.

The latest Nasdaq milestone shows how strongly artificial intelligence remains connected to global financial-market sentiment in 2026.
