The Strait of Hormuz situation has moved over the weekend and is the most immediately market-relevant story in the batch. Fresh US strikes on Iranian radar sites and Iranian attacks that Kuwait has now publicly condemned suggest the ceasefire framework is under serious strain. Satellite analysis seen by BBC Verify indicates Tehran’s strikes were more precise and more extensive than Washington has publicly acknowledged, which matters for how you read the balance of escalation risk.

The strategic framing matters more than the product itself — it confirms Nvidia is serious about moving down the stack from data centres into consumer and enterprise endpoints.

OpenAI separately solved an 80-year-old mathematics problem using one of its models. The research community will debate the significance, but for anyone watching AI capability trajectories, it is a concrete demonstration of frontier model performance on formal reasoning tasks that goes beyond benchmarks.

The Economist has a piece out arguing private credit markets need to reprice assumptions built on cheap capital and predictable exits. Worth reading if you have exposure there — the argument is that the stress hasn’t shown up yet but the conditions that masked it are gone.
