Good morning.

The man who taught the Federal Reserve to speak in riddles has gone quiet. Alan Greenspan, who chaired the central bank for more than 18 years across four presidents, died Monday at age 100. For a generation of traders he was "the Maestro," the man whose every mumble about "irrational exuberance" could move markets before anyone was sure what he'd actually said. He leaves the stage just as his old institution turns sharply hawkish under a brand-new conductor, which is its own kind of eulogy: the Fed Greenspan built now belongs to someone else, and that someone is in no mood to cut.

Markets

The market spent a year flying first class on artificial intelligence. Tuesday it found the seatbelt sign.

US stock futures buckled before the open, led by the same megacap and chip names that powered the climb. Nasdaq 100 futures fell about 2.5%, putting the index on pace to erase more than $1 trillion in market value in a single session, while S&P 500 futures dropped 1.35% and the Dow held up better with a 0.5% dip. The fear gauge did the rest of the talking, with the VIX jumping roughly 14% toward 20.

This isn't one bad headline. It's two anxieties arriving together: a creeping doubt about whether all that AI spending will ever pay for itself, and a hard repricing of what the Fed does next.

The selloff has a cruel symmetry, because the biggest winners are giving back the most. Memory chips, the best-performing corner of the S&P 500 this year, led the dive, and the hyperscalers that have committed tens of billions to AI build-outs are being asked, again, to show the returns.

By the numbers:

Not everyone thinks the central bank is the story. Economist Nouriel Roubini argued on Bloomberg Television that investors are too "obsessed with the Fed" and that the AI boom remains the dominant force in this market, whatever rates do. The bulls' problem is that on Tuesday, both worries were pulling the same direction.

Buckle Up: A 14% pop in the VIX off a low base isn't panic; it's the cabin realizing the air got thin. The real test is whether the rate repricing sticks, because a market that spent a year betting on cuts cannot re-rate to hikes without a few stomach-dropping sessions. Watch the long end of the Treasury curve and Friday's inflation print for whether this is an air pocket or the start of a longer descent.

Big Tech

The most valuable thing in the AI race isn't a chip or a data center. It's the people who know how to use them, and Google just watched two of its best walk out the door.

Alphabet (GOOGL) fell as much as 7% on Monday, its steepest single-session drop in more than a year, after two landmark researchers left for rivals within days of each other, CNBC reported. Noam Shazeer, a vice president of engineering and co-lead of the Gemini models and a co-author of the 2017 "Attention Is All You Need" paper that gave the world the transformer, departed for OpenAI. Days later John Jumper, who shared the 2024 Nobel Prize in Chemistry for AlphaFold after nearly nine years at DeepMind, announced he was joining Anthropic.

The back-to-back exits lopped roughly $250 billion off Alphabet's value and landed on the market's rawest nerve: the worry that the AI lead any one company holds is thinner, and more poachable, than the share price assumes.

Big Tech has spent two years treating elite researchers like franchise quarterbacks, and the transfer market is just as ruthless. Shazeer's case is the sharpest reminder of the stakes: Google paid a reported $2.7 billion in 2024 to bring him back through a deal for his startup Character.AI, only to lose him to the very rival he was hired to fight.

The market read it as more than gossip. Premarket Tuesday, Alphabet slipped another 2.1% as the broader tech tape sold off, extending a slide that began the moment investors started asking whether a moat made of talent holds when the talent has options. Anthropic, fresh off its own confidential IPO filing, just made the answer look more uncomfortable by hiring a Nobel laureate away from Google.

Talent Tax: Alphabet still owns world-class labs, custom silicon and a search engine that prints cash, none of which left with the researchers. But the departures put a number on an old anxiety, and in a week when the whole AI trade is wobbling, a brain drain is the last story Google wanted leading the tape. The fix isn't a product launch; it's convincing the next Shazeer that the best place to build the future is still in-house.

Markets

Most companies tap the bond market because they're short on cash. SpaceX is doing it with a vault that would make a sovereign nation blush.

Ten days after the largest IPO in history, SpaceX (SPCX) kicked off its first-ever investment-grade bond sale, seeking around $20 billion even though it's sitting on roughly $100 billion in cash, most of it freshly raised. The deal carries investment-grade ratings from all three major agencies, and demand is expected to be ferocious. The catch is that the equity side hasn't been nearly as kind: the stock slid for a third straight session, dropping below a $2 trillion valuation for the first time since its debut after shedding more than $600 billion over three days, though it still trades about 9% above its $135 offer price.

So why borrow against a war chest? Because the war chest isn't big enough for what comes next.

SpaceX is no longer just rockets and Starlink dishes. It is pitching itself as the next great AI infrastructure player, and that ambition burns cash at a rate that even an $86 billion IPO can't cover. Bloomberg Intelligence frames the bond sale as a down payment on a spending spree, not a rescue.

Buy Now, Ask Later: The bond market's enthusiasm for a cash-rich, founder-defined business says as much about the appetite for AI exposure as it does about SpaceX. Credit investors are betting on present leverage and a famous name; equity investors are betting on a future that's still mostly slideware. For now the two camps disagree loudly, and the gap between a feeding-frenzy bond book and a three-day stock skid is the whole story.

Monday buried a Fed legend; Tuesday opened with the Fed he built threatening to hike into a tech selloff. The AI trade lost altitude, Google lost two brains, and SpaceX went looking for $20 billion it technically doesn't need. The throughline is confidence — in talent, in the boom, in the idea that you can always borrow against tomorrow. Micron's number lands Wednesday, the Fed's favorite inflation gauge hits Friday, and somewhere a Maestro is reminding us that exuberance has a habit of getting irrational. Keep your trays in the upright position.

That's the tape. We'll see you at the open. — AllThingsWallSt
