The Closing Bell

Stocks closed at fresh record highs again, but the rally keeps riding on fewer and fewer names, and Jamie Dimon just told investors the bill for all this AI spending is starting to show up in the cost of money.

The Fed, rates, and a warning from the top.

Treasuries held steady, with the 20-year proxy (TLT) up slightly and the dollar (UUP) off modestly, but the macro story of the day came from JPMorgan's Dimon, who said the AI buildout is now competing directly with government borrowing for capital and that "rates are going up" as a result. That lands alongside fresh trade data showing imports running well ahead of exports, a reminder that the deficit backdrop isn't going away. Small caps (IWM) lagged, down 0.7% while the S&P and Nasdaq (QQQ) both ground higher, underscoring that the move higher is happening in a narrow lane, not across the economy.

AI and chips carry the tape, but breadth is the real story.

Broadcom (AVGO) jumped 3.7% and AMD (AMD) added 2.8% after Marvell's investor day and comments from AMD CEO Lisa Su reinforced confidence in chip demand; Citigroup responded by lifting its AMD price target to $800. JPMorgan flagged Micron's AI memory cycle as a potential $100 billion cash windfall. Nvidia (NVDA) itself barely budged, up just 0.1%, and that gap didn't go unnoticed: strategist David Rosenberg argued Nvidia's strength is "masking a whole lot of pain" in the broader market, a theme echoed by reporting that just 3% of S&P 500 stocks are behind the index's record run and that Nvidia, Apple (AAPL), and Microsoft (MSFT) alone now drive 21% of the benchmark. Elsewhere in AI infrastructure, Google (GOOGL) and Constellation Energy's (CEG) 20-year, 890-megawatt nuclear power pact lifted a wide swath of data center and power names, while Nokia (NOK) and Ciena (CIEN) rallied on comments from Nokia's CEO that AI customers would build data centers twice as fast if supply allowed.

Winners and losers.

Carnival (CCL) and Marvell (MRVL) were among the day's standout gainers. On the downside, Vaxcyte (PCVX) sold off after announcing a combined $1 billion equity and convertible notes offering, while Novavax (NVAX) and Moderna (MRNA) gave back recent gains amid reports of a suspected pneumonic plague outbreak in Russia. Western Digital (STX/WDC) dropped, ArriVent BioPharma (AVBP) hit a 52-week low after its lung cancer drug failed its primary endpoint, and microcap NFT Limited was repeatedly halted on circuit breakers, ending down more than 70%. Apogee Enterprises (APOG) reported before the bell, with pricing power and acquisitions cited as offsets to inflation pressure.

After the bell and tomorrow.

Constellation Brands (STZ), Penguin Solutions (PENG), Neogen (NEOG), and Worthington Steel (WS) report after the close tonight. Bitcoin held near $85,000 with Coinbase (COIN) catching a bid on a favorable CFTC ruling. Watch whether chip strength can broaden out, or whether tomorrow's earnings crop reinforces the narrow-leadership worry.

Bottom line: records are being made at the top of the market, but the rally's foundation is getting narrower, and rising rate pressure from the AI capital race is the crack to watch.
