The S&P 500 rose 0.3% to a fresh record high on Thursday, while the Nasdaq gained 0.6% and the Dow Jones hovered near the flatline. Investors kept a cautious eye on the ongoing US government shutdown, though markets largely shrugged off concerns, awaiting further developments and hoping the stalemate proves short-lived. Technology led sector gains after OpenAI raised $6.6 billion in a share sale valuing the company at $500 billion and announced an agreement with South Korean chipmakers. Industrials, energy and consumer discretionary stocks also advanced, while real estate lagged. Among megacaps, Nvidia (+1.8%), Broadcom (+2.6%), and Oracle (+1.7%) posted strong gains. Also, Tesla added more than 1% as its global vehicle deliveries rose 7.4% in Q3, marking a surprising rebound and helped by the EV tax credit expiration in the end of September. On the other hand, Amazon shares slipped nearly 0.5%.
