Energy sectors also saw significant gains as crude oil prices surged, reflecting tightening global supplies and geopolitical tensions.

The S&P 500's ascent was largely fueled by the relentless demand for AI chips, with major technology players continuing to drive market sentiment. Investors remain keenly focused on the upcoming earnings reports from several "Magnificent Seven" companies, which are expected to provide further direction on the sustainability of the current AI-driven rally.

Energy markets experienced a significant surge, with Brent Crude topping $109 per barrel as emergency stockpiles reportedly drained at a record pace.

In corporate news, Organon (OGN) shares soared by 27% following an all-cash acquisition deal by Sun Pharma, highlighting continued M&A activity in the pharmaceutical sector. Conversely, POET Technologies (POET) saw its stock plummet by nearly 50% after the unexpected termination of a key AI partnership with Marvell, demonstrating the volatility inherent in high-growth tech ventures.

Persistent inflation remains a key concern for central banks, with recent data suggesting that price pressures are not abating as quickly as hoped. This ongoing challenge continues to shape monetary policy expectations, keeping interest rate decisions at the forefront of market participants' minds.

Adding to the tech landscape, a Federal Reserve study linked the rise of generative AI tools like ChatGPT to a significant slowdown in US programmer job growth.
