The week the AI trade split in two

Last Sunday we said the vote and Washington's borrowing plan would set the price of AI's bill. Both arrived. The vote mattered more.

Democrats took both chambers on Tuesday. Wednesday, the Dow rose about 3% while chip stocks fell. Thursday, the selling reached everyone. The Nasdaq fell 5.5%, into a correction, and the semiconductor index fell 12.2%. Friday's strong jobs report and a partial chip rebound only dented the damage.

The line ran through the AI trade itself. The companies that sell the buildout fell hardest. The companies that pay for it fell far less.

The other five stories came at the same week from different sides. Oil lost its war premium without a deal. Memory costs reached your phone. Hiring surged, and the Fed's hike bet held. Raising money got visibly more expensive. And prediction markets lost ground in court.

The sellers of AI took the hit

On Thursday, AMD (AMD) and Micron (MU) lost about 17% each and Nvidia (NVDA) about 9%. Microsoft (MSFT) and Meta (META) fell about 4%. Amazon and Alphabet lost about 2%.

The trigger was political. Texas elected Gina Hinojosa, who pledged to ban data-center approvals until lawmakers pass protections. UBS estimated that about 30% of expected 2028 U.S. data-center additions could be at risk from construction pauses. Wednesday's selling in power and construction names priced a campaign pledge, not a policy. Hinojosa doesn't take office until January.

The split follows the money. A slower data-center build is lost revenue for the chip seller. For the buyer, it's a smaller bill.

Nothing in the orders has changed yet. AMD guided fourth-quarter revenue to about $17 billion and expects server revenue to double next year. Asia sold anyway. Seoul's Kospi fell 6% on Friday, as foreign investors ran and local buyers caught them.

For now, the suppliers carry the policy risk. The buyers hold an option to spend less.

Oil gave back its war premium. Nobody signed anything.

Brent fell about 8% on Wednesday, below $100 for the first time in about a month. It was on course for its biggest weekly drop since April 2020.

What changed was Washington. President Trump told the Financial Times the U.S. had no immediate plans to strike Iran. Vice President JD Vance wrote that "the reason we lost is the war."

Tehran didn't move. Iran has sent a nuclear proposal through Qatar, a senior official told Reuters, but wants seven demands met first, including sanctions relief and war reparations. The U.S. struck Iran's Qeshm Island early in the week, the Wall Street Journal reported. Tanker attacks kept running near a record pace, according to Britain's maritime agency.

The refiners paid first. Marathon Petroleum (MPC) fell about 9.5% on Wednesday. CVR Energy (CVI) sold new stock at $47.55 to fund a refinery purchase priced on war-era margins, and its shares slid below that within a day.

Oil now carries a political premium instead of a military one. Politics can change in a single post.

Your phone is paying AI's memory bill

Apple (AAPL) had its best September quarter ever and raised prices on iPhones, Macs and iPads. It still guided holiday-quarter gross margin to 45% to 46%, citing "primarily the impact of higher memory costs." Chief Executive John Ternus called memory pricing "unprecedented."

Stripping out last quarter's tariff refunds, that's a step down of one to two points. Apple can absorb it. The rest of the phone market can't.

Qualcomm (QCOM) showed who pays. Its phone-chip revenue fell 26%, partly on lost Apple business, as global smartphone shipments dropped to a 14-year low, according to Counterpoint figures cited by Reuters. Arm's royalties grew just 8%. Arm blamed memory prices, which hit mid- and lower-tier phones hardest.

AI servers are outbidding phones for memory. Qualcomm's answer is to raise its own prices, which makes the phone more expensive again.

The memory makers are winning the auction. Everyone paid by the unit is paying for it.

Hiring surged. The hike bet held.

Employers added 165,000 jobs in October, more than double the roughly 65,000 expected. Unemployment fell to 4.1%. Hourly pay rose 0.4% in the month, and revisions added 84,000 jobs to August and September.

The report landed on a jumpy rate market. On Thursday, as stocks fell, Kalshi's December hike contract slid from 80 cents to as low as 62. After Friday's report, futures put a December hike back near 77%, CME FedWatch data showed.

Cheaper oil pulled expected inflation down, with one-year inflation swaps near 2.1% from 2.7% a week earlier. But the Fed officials who wanted a hike haven't moved. Abroad, the Bank of England hiked to 4% and Australia raised rates too.

Treasury kept its auction sizes steady but dropped "at least" from its promise to hold them. The 10-year yield closed Thursday at 4.84%, below the 4.93% where the week began.

Oil gave the Fed a reason to wait. Jobs took it back.

Raising money got more expensive, in plain sight

On Oct. 28, Oracle (ORCL) promised to cap new outside funding at $20 billion through 2030. Five days later it raised all of it. Half came as stock at $116. The other half came as notes with coupons of up to 8.65%, about $777 million a year of new interest.

Marvell (MRVL) agreed to buy Lumentum for 4.5 of its own shares per share, a headline $1,132. Marvell's stock had fallen about a third since that price was set, so the offer was worth about $763 on Monday afternoon. Marvell owes $5.8 billion if the deal fails in certain circumstances.

MasTec went the other way. It suspended late-stage talks on a large acquisition to prioritize buying back its own stock.

When the buyer's stock is the currency, the buyer's chart sets the price. When debt is the currency, the coupon does.

Prediction markets lost ground in court

DraftKings (DKNG) cut its 2026 profit forecast to $175 million to $275 million of adjusted EBITDA, from $700 million to $900 million in August. It will spend $650 million to $700 million this year on Predictions, its prediction-market product. Its own deck modeled sports contracts ending on July 31, 2028. The stock was down more than 20% on Friday.

The courts moved against the product. The Second Circuit refused to stop New York and Connecticut from enforcing gambling laws against Kalshi's sports contracts. The Ninth Circuit declined to rehear its ruling for Nevada. Arkansas sued Kalshi.

States don't need a final ruling to shrink the market. After Utah charged Kalshi's founders, DraftKings and FanDuel pulled sports contracts there within two days.

Kalshi raised money last week at $40 billion. DraftKings and FanDuel's parent, Flutter, were worth about $26 billion combined before Friday's drop. DraftKings is spending to close that gap while the courts decide whether the gap is worth closing.

THE MARKET SIPS TAKEAWAY

This week the market drew a line through the AI trade. The companies selling the buildout took the political risk. The companies paying for it got to keep their option to spend less.

The rest of the week rhymed. Oil dropped on a political mood, not a deal. Memory costs moved down the supply chain to phones. Money got more expensive for anyone who had to raise it.

The read holds if Microsoft, Meta, Amazon and Alphabet keep beating the chipmakers on down days. It breaks if supplier orders stay strong and the chip selloff reverses. Tomorrow, we look at the week that tests it.

UNTIL THEN, SIP SLOWLY!
