The 10-minute window delivers two high-significance market-moving signals: a major geopolitical escalation in the Strait of Hormuz and a significant antitrust development involving Amazon. The Strait of Hormuz, a critical chokepoint carrying roughly 20% of global oil consumption, is reportedly closed for the first time in modern history, corroborated by BBC, Reddit, and jetstream.bsky sources. This directly follows President Trump's statement that the US will not lift its blockade until a deal is made with Iran, escalating tensions and threatening sustained oil supply disruption. Concurrently, a breaking antitrust allegation from The Guardian via jetstream.bsky claims Amazon colluded with Walmart and Chewy to raise online prices, potentially triggering regulatory scrutiny and legal risk for Amazon's core e-commerce business. A secondary, lower-significance signal is the IEA report that data centers drove half of US power demand growth in 2025, highlighting energy intensity of AI infrastructure but lacking immediate price action. Other items, including earnings beats (Northfield Bancorp, Servisfirst Bancshares), psychedelic stock surges on Trump's executive order, and various geopolitical snippets (Ukraine air alerts, US-Mexico trade talks), are either noise or lack specific, actionable US market impact within the next 1-8 hours.
