Markets surged as the S&P 500 reached a record high, driven by optimism regarding a potential U.S.-Iran agreement to reopen the Strait of Hormuz. Despite the bullish sentiment, the earnings landscape remained complex; while companies like SpaceX and AMD posted strong revenue beats, investors demonstrated caution regarding high capital expenditures, particularly in AI-focused initiatives, causing volatility. The regulatory environment was similarly active. New Jersey filed a federal antitrust lawsuit against Amazon, and the Supreme Court unveiled its October docket, which includes major disputes on climate change and privacy. State-level regulatory friction was also evident, as Texas paused new data center approvals pending an audit. Meanwhile, geopolitical instability continued to simmer, with reports highlighting significant growth in Colombian narco-terrorist groups and recurring power grid failures in Cuba.
