US markets jump on AI rally as yields ease and oil slips

US stock markets jumped sharply on Monday, led by strong gains in artificial‑intelligence names such as Advanced Micro Devices. The chipmaker’s rise helped push the main indices higher. At the same time, Treasury yields pulled back from their recent peak, easing pressure on the market. Crude oil prices also fell, reaching an eleven‑day low. Meta Platforms saw its shares soar after analysts raised their price targets following the launch of the company’s new AI assistant. The combined effect of AI optimism, lower bond yields and cheaper oil gave investors a fresh boost on the trading floor. The rally was noted in the Economic Times market update at 01:27 AM IST on 22 September 2026.
