Good morning. The Fed tanked markets yesterday, the FAA is overhauling air travel safety, Nvidia just made the boldest market prediction in tech history, and a woman in Utah was just convicted of poisoning her husband with fentanyl. Let's get into it.
⚡ BIG STORY
The Fed Held Rates — And Stocks Had Their Worst Day of 2026
Yesterday was painful. The Federal Reserve voted 11-1 to hold its benchmark interest rate steady at 3.5%-3.75% — exactly what markets expected. So why did stocks absolutely crater? Because of what Fed Chair Jerome Powell said in the press conference that followed.
The damage:
The Dow Jones dropped 768 points — its worst single day of 2026 — closing at 46,225 and falling below its 200-day moving average for the first time this year. The S&P 500 fell 1.36% to 6,624. The Nasdaq dropped 1.46%. The Dow is now down more than 5% in March alone — on pace for its worst month since 2022.
What Powell actually said that spooked everyone:
Powell told reporters that inflation projections for 2026 are now higher than the Fed expected at the start of the year. The economic disruption from the Middle East is making it harder to predict when rate cuts will come. And the Fed is now in a genuinely difficult position — it can't cut rates to stimulate the economy without risking an inflation surge from rising energy prices. The committee said it needs 'greater confidence' that inflation is moving back toward its 2% target before making any moves.
The one bright spot: Nvidia. While every other Magnificent Seven stock fell over 1% yesterday Nvidia closed up 0.4% — the only major tech stock to finish green. More on that in the AI section below.
NexoBrief take: The Fed is stuck between a rock and a hard place. High energy prices from the oil shock are pushing inflation up — which means rate cuts get pushed further out. Don't expect relief on mortgage rates, car loans, or credit card APRs anytime soon. Plan accordingly.
💰 MONEY MINUTE
Your Portfolio Just Had Its Worst Week of 2026 — Here's What Not to Do
If you checked your investment account this week and felt sick — you're not alone. Between the market selloff, oil price volatility, and Fed uncertainty, most diversified portfolios are down 5-8% from their January highs. Here's the most important thing NexoBrief can tell you right now:
Do not sell.
Selling during a market downturn locks in your losses permanently. The investors who panic-sold during the 2020 COVID crash, the 2022 rate hike selloff, and the 2008 financial crisis all missed the subsequent recoveries that wiped out those losses and then some. The S&P 500 has recovered from every single downturn in its history. Every one.
What smart investors are actually doing right now:
Continuing automatic contributions without looking at the balance. Treating the dip as a discount — buying index funds at lower prices than last month. Rebalancing toward assets that perform well in inflationary environments — energy stocks, commodities, TIPS bonds, and real estate.
The one thing worth reviewing: Your timeline. If you need this money in the next 1-3 years it should not be in stocks regardless of what the market does. If your timeline is 10+ years this week's noise is completely irrelevant to your outcome.
NexoBrief quick take: Market volatility feels awful. It is also completely normal. The investors who build real wealth are the ones who stay in the game when everyone else is running for the exits.
🤖 AI TOOL OF THE DAY
Nvidia Just Said AI Chips Are a $1 Trillion Market — Here's What That Means For You
At its GTC conference this week Nvidia CEO Jensen Huang made the boldest market prediction in tech history: he said the AI chip market represents at least a $1 trillion revenue opportunity through 2027. For context — Nvidia's entire revenue last year was $130 billion. He's predicting the market grows nearly 8x.
What Nvidia actually announced that backs this up:
The next generation Vera Rubin chip platform — more powerful than the current Blackwell chips that are already selling faster than Nvidia can make them. A major push into AI inference — the day-to-day work of running AI models inside real products rather than just training them. And a robotics platform that Jensen called 'the next wave of AI' — physical AI that can see, understand, and interact with the real world.
Why this matters for your career and your money: Every AI tool you use daily — ChatGPT, Claude, Midjourney, Perplexity — runs on Nvidia hardware. If Nvidia's $1 trillion prediction is even half right, the AI tools available to you in 2027 will be dramatically more powerful and dramatically cheaper than what exists today. The productivity gap between people who use AI tools and people who don't is about to get much wider.
NexoBrief verdict: Nvidia is not just a chip company — it's the foundation of the entire AI economy. Understanding what they build helps you understand where AI goes next. The GTC keynote replay is at nvidia.com and worth watching.
🚀 STARTUP SPOTLIGHT
Microsoft vs OpenAI — The AI Partnership That's Starting to Crack
The most important business relationship in tech is showing serious signs of strain. Microsoft invested $13 billion into OpenAI and built its entire Copilot AI product strategy around exclusive access to OpenAI's models. Now OpenAI is reportedly looking to reduce its dependence on Microsoft's Azure cloud — and Microsoft is said to be considering legal action over cloud rights.
What's actually happening: OpenAI needs more computing power than Microsoft can provide fast enough. To meet demand it has been routing some workloads to Amazon Web Services and Oracle — direct competitors to Microsoft's Azure. Microsoft's contract with OpenAI reportedly gives it preferred cloud provider status. OpenAI's workaround may be breaching that agreement.
The deeper tension: OpenAI is transitioning from a nonprofit to a for-profit company and needs to generate returns for investors beyond just Microsoft. That means building its own cloud business, selling directly to enterprise customers, and reducing the revenue share that flows back to Microsoft. These are fundamentally conflicting interests.
Why this matters for everyone: If the Microsoft-OpenAI partnership fractures it reshapes the entire AI landscape. Amazon, Google, and Oracle all become stronger AI players overnight. Startups building on OpenAI's API face uncertainty about pricing and access. And Microsoft suddenly has a $13 billion bet that's not paying off the way they planned.
NexoBrief take: The biggest AI story of the next 12 months may not be a new model or a new chip — it could be the breakup of the partnership that defined the first wave of the AI boom. Watch this one closely.
🌍 CURRENT EVENTS
FAA Overhaul, Fentanyl Murder Conviction, AI Deepfake Victims, and More
Four stories today that have nothing to do with oil prices or geopolitics — but affect your daily life directly:
The FAA is overhauling air travel safety:
Following last year's deadly collision between an American Airlines jet and a US Army Black Hawk helicopter near Washington DC that killed 67 people the FAA announced sweeping new safety rules this week. The agency is suspending the use of visual separation between planes and helicopters in congested airspace around major airports. If you fly regularly out of DC, New York, Chicago, or LA — expect new procedures and potentially longer taxi times as controllers adjust to stricter protocols.
The fentanyl murder conviction:
A Utah jury convicted Kouri Richins of fatally poisoning her husband's drink with fentanyl in 2022 — a case that made national headlines partly because Richins had written a children's book about grief after her husband's death. She was found guilty of aggravated murder and four other charges including forgery and fraud. The case is a stark reminder of the fentanyl epidemic's reach into unexpected corners of American life.
Teenage girls targeted by AI deepfakes:
Three teenage girls are suing AI company xAI — Elon Musk's artificial intelligence startup — alleging that its image generation tools were used to create nonconsensual nude images of them without their knowledge or consent. The case is the latest in a growing wave of litigation targeting AI companies for enabling image-based sexual abuse. At least 40 states now have legislation pending or passed targeting AI-generated deepfake content.
Avian flu update:
Montana State University received a $1.9 million federal grant to study avian flu — as the virus continues spreading through US poultry and dairy cattle populations. The CDC confirmed this week that human cases remain rare but the economic impact on egg and poultry prices is significant. Egg prices are up 47% year over year nationally — a direct result of the ongoing avian flu outbreak wiping out laying hen populations.
NexoBrief take: Four stories that touch aviation safety, the justice system, AI regulation, and your grocery bill. The deepfake litigation and the FAA overhaul are both stories with long tails — expect both to be in the news for the rest of 2026.
