Good morning. Trump landed in Beijing with Jensen Huang — the Nvidia CEO joined the presidential delegation. Kevin Warsh is confirmed as the new Fed chair. The Iran war has cost $29 billion. Hackers used AI to create the first documented zero-day exploit. And scientists found a molecular switch in brown fat that could replace Ozempic. Let's go.
⚡ BIG STORY
Trump Landed in Beijing With Jensen Huang. The Nvidia CEO Is in the Presidential Delegation.
Trump arrived in Beijing Tuesday for his summit with President Xi — and in a move that signals exactly what's at the center of this meeting, Nvidia CEO Jensen Huang joined the presidential business delegation. The most powerful AI chip company on earth, whose chips China desperately wants and the U.S. has restricted, sitting at the table as part of America's official party.
The summit agenda is dense: rare earth export controls, semiconductor restrictions, Taiwan, trade tariffs, and AI governance. China suspended rare earth exports and banned semiconductors from Dutch chip company Nexperia earlier this year — a direct retaliation for U.S. chip controls. The key outcome both sides are working toward is a mutual de-escalation: the U.S. eases some chip export restrictions, China resumes rare earth exports. Huang's presence signals the U.S. sees that trade as worth making.
What happened overnight:
S&P 500 hit another record Tuesday, driven almost entirely by tech stocks — most of the broader market actually declined on the day. The AI trade is narrowing to a smaller and smaller group of winners
Samsung Electronics briefly shed $66 billion in market cap Tuesday on fears of a worker strike — South Korean authorities intervened to calm markets, and shares partially recovered
The Pentagon told Congress Tuesday that the war has cost $29 billion so far — the largest single military expenditure since the Iraq War
NexoBrief take: Jensen Huang in the presidential delegation to Beijing is the most important business-geopolitics story of the week. Nvidia is simultaneously the company China most wants access to and the company the U.S. most wants to restrict. Having its CEO at the table is either a signal of imminent deal-making or an extraordinary piece of theater. The outcome will move Nvidia's stock significantly in either direction.

Kevin Warsh Is Confirmed as Fed Chair. Here's What Changes — And What Doesn't.
The Senate confirmed Kevin Warsh as the next chair of the Federal Reserve Tuesday in a 56-43 vote. He takes over from Jerome Powell, who will remain on the Board of Governors. Warsh, 56, is a former Fed governor and Morgan Stanley investment banker who has been publicly critical of Powell's approach to inflation — arguing the Fed was too slow to tighten and too quick to signal loosening.
The 8-4 dissent at Powell's final meeting two weeks ago was a preview of the direction Warsh is likely to take: more hawkish, more skeptical of cutting rates, and more willing to hold even if unemployment ticks up. Markets have already partially priced this in — the yield curve has steepened since his nomination was announced.
What actually changes under Warsh:
Rate path: Warsh is expected to slow or pause the Fed's rate-cutting cycle. Markets were pricing in two cuts in 2026; that forecast is now in question
Communication style: Powell was known for careful, consensus-driven messaging. Warsh is more direct and has a history of public dissent — the Fed's communications will become less predictable
Relationship with the White House: Trump has been openly critical of Powell for years. Warsh is a Trump ally, but has said publicly he will make decisions independently. That independence will be tested immediately
NexoBrief take: The Fed just got its most significant leadership change since 2018. Warsh is smart, credentialed, and genuinely hawkish — this is not a rubber stamp for whatever Trump wants. But the direction is clear: rates stay higher for longer than Powell would have allowed. Mortgage rates, corporate borrowing costs, and the housing market all adjust accordingly.
🤖 AI TOOL OF THE DAY
Hackers Used AI to Create the First Documented Zero-Day Exploit. This Changes Cybersecurity.
Security researchers confirmed Tuesday that a hacking group used an AI system to independently discover and exploit a previously unknown vulnerability in a widely-used open-source package — the first publicly documented case of AI being used to generate a zero-day exploit in a real-world attack. The attack hit npm packages tied to Mistral, UiPath, and TanStack, injecting malicious code into the software supply chain.
A zero-day exploit is a vulnerability that the software's developers don't know about yet — meaning there's no patch, no defense, and no warning. Finding them has historically required highly skilled human researchers working for weeks or months. The AI found one and weaponized it autonomously. This is the scenario the five-nation cybersecurity warning from last week was pointing at.
Why this is a threshold moment:
The cost of finding vulnerabilities just dropped dramatically. What required a team of expert hackers now requires access to an AI model and some prompt engineering
Open-source software supply chains are the most exposed — packages used by millions of developers are now potential attack surfaces that AI can probe faster than humans can defend
OpenAI launched a $4 billion enterprise AI deployment company today — called OpenAI Enterprise — to help companies deploy AI safely at scale. The timing is notable: the same day AI is confirmed in a live cyberattack
NexoBrief take: The Vulnpocalypse isn't coming. It's here. The first documented AI zero-day in a real-world attack is the before-and-after moment for cybersecurity. Every security team in every company should be reading this report today.
🚀 STARTUP SPOTLIGHT
SoftBank Just Put $450 Million Into a British AI Chip Startup. Here's Why That Matters.
SoftBank invested $450 million in Graphcore — a Bristol-based AI chip startup founded in 2016 that has been building specialized processors for AI workloads. The investment values Graphcore at approximately $2.8 billion and gives SoftBank a controlling stake. It is the largest single investment in a UK AI chip company in history.
Graphcore's Intelligence Processing Unit, or IPU, is architecturally different from Nvidia's GPU. GPUs were designed for graphics and repurposed for AI. IPUs were designed specifically for the way AI models think — optimized for the sparse, irregular computation patterns that neural networks actually use. The company has been competing against Nvidia for enterprise AI deployments and has customers including Microsoft, Dell, and several major research institutions.
Why this deal matters right now:
The Beijing summit has put AI chip supply chains at the center of U.S.-China geopolitics. A British AI chip company with $450 million from SoftBank becomes a strategically significant alternative to both Nvidia and Chinese chip ambitions
The UK government has been pushing to become a global AI hub — the Graphcore investment is the largest validation of that strategy yet and lands during a week when Jensen Huang is literally in Beijing with the U.S. president
SoftBank has been building an AI chip portfolio alongside its ARM Holdings position. Graphcore, ARM, and potential investments in other chip startups suggest SoftBank is trying to own the AI hardware stack the way it tried to own real estate tech with WeWork — but with better underlying assets
NexoBrief take: Graphcore is the most credible alternative AI chip company in the Western world. $450 million from SoftBank in a week where AI chips are literally the subject of a presidential summit is either the best timing in startup history or a sign that SoftBank knows something about what's being negotiated in Beijing. Either way — watch Graphcore.
🌍 CURRENT EVENTS
Scientists Found a Fat-Burning Switch. GM Is Cutting 500 IT Jobs. Beer Demand Is Falling.
Scientists found a molecular switch in brown fat:
Scientists at McGill University uncovered a hidden molecular switch in brown fat — the body's heat-generating fat — that triggers an alternative calorie-burning system. The switch is activated by glycerol, a molecule released when fat breaks down in the cold. The enzyme it activates, TNAP, produces heat by burning calories through a completely different mechanism than anything current weight-loss drugs target. This is not a GLP-1 pathway. It's a new pathway entirely — and if it can be activated pharmacologically, it could produce a weight-loss drug that works differently from Ozempic and with fewer side effects.
Three more quick:
GM is laying off 500 to 600 salaried IT workers as it restructures toward AI-fluent technical roles. The automaker is becoming a software, autonomy, and AI company — and discovering its existing IT workforce doesn't map onto the skills it needs
Beer demand is falling as gas prices surge — a new data analysis shows that when gas tops $4 a gallon, discretionary spending on alcohol drops measurably. Americans are choosing between the pump and the pub, and the pump is winning
U.S. students showed meaningful improvement in math scores on the latest national education assessment — the first significant positive movement since the COVID learning loss era began. Small but real progress
NexoBrief take: The brown fat molecular switch is the most genuinely exciting obesity research published in months. A new calorie-burning pathway that isn't GLP-1, activated by a molecule the body already produces naturally, with no pharmaceutical side effects yet — that's the kind of finding that starts a new drug class. File under: watch this carefully over the next two years.
