1. NVIDIA Scales Back OpenAI Data Center Guarantee
Per WSJ, NVIDIA and OpenAI are nearing a financing deal for a 10GW data center campus in Ohio, but the deal structure has been revised: NVIDIA’s guarantee reduced from $250B to under $120B, covering only 5GW, in response to investor concerns over financial risk.
2. Trump Urges Americans to Accept Higher Oil Prices
Trump stated in a New York speech that Americans should “accept higher gas prices” as the cost of stopping Iran from obtaining nuclear weapons, and again claimed he would declare the Strait of Hormuz as US territory after “defeating Iran.”
3. Iran Responds Forcefully to Trump
Iran’s Deputy Foreign Minister responded that “the Strait of Hormuz cannot be controlled by a tweet, an aircraft carrier, or an executive order”; IRGC Navy Commander stated the strait remains under full Iranian military control.
4. UAE Vessel Attacked in Strait of Hormuz

π§ Assessment
Middle East geopolitical risk continues to escalate β Trump’s “takeover of Hormuz Strait” rhetoric combined with repeated attacks on UAE vessels puts strait transit security in focus.
Oil prices fell rather than rose, indicating the market has not yet priced in strait disruption risk, trading more on demand-supply balance.
NVIDIA scaling back OpenAI guarantees marks the first major “retreat” signal in the AI infrastructure boom β investors are beginning to question the sustainability of AI capital expenditure.
US markets closed for weekend; watch next week’s open for pricing of geopolitical risk and AI sector adjustment.
