Wednesday's modest post-FOMC advance gave way to a split premarket: the S&P 500 closed at 7,743.98, up 0.28% for a third straight gain, the Dow added 0.19% to 52,475, the Nasdaq Composite rose 0.27% to 26,550, and the VIX slipped to 16.91 after the Federal Reserve held rates at 3.75–4.00% in a 10–2 vote, with two policymakers favoring an immediate hike. The AI trade delivered its verdict after the bell — Microsoft beat on nearly every line and rose about 4% premarket, while Alphabet missed on earnings and revenue, posted negative free cash flow of $9.07 billion, and fell more than 10% premarket even as it held its full-year capital-expenditure forecast near $200 billion. That split has Nasdaq 100 futures down roughly 1.2% while Dow futures — light on Alphabet — point about half a percent higher. The morning's double header at 8:30 AM ET — the advance Q3 GDP estimate and September PCE — lands directly on this fault line: consensus expects growth of 3.1–3.2% annualized and core PCE up 0.3% on the month, and any meaningful deviation reprices the December hike odds that jumped toward 83% after Wednesday's hold.

8:30 AM Update — Q3 GDP and September PCE

Added 8:46 ET. Advance Q3 GDP printed +3.4% annualized vs +3.1% expected (+2.2% in Q2) — a growth beat on the week's biggest data point. September PCE landed in line: headline +0.5% m/m and +3.6% y/y, core +0.3% m/m and +3.1% y/y; initial jobless claims came in at 194K vs ~198K expected (prior week revised to 195K). The futures reaction was muted: at ~8:31 AM ET the S&P 500 held −0.37%, Nasdaq 100 −1.15%, and Dow futures −0.29% — roughly where they stood before the release — while the 10-year eased to ~5.01%. Desk judgment: this lands between the morning's in-line and hot scenarios — stronger growth plus on-plan inflation keeps the December-hike pricing that sat near 83% before the release roughly intact, leaning firmer rather than repricing sharply. The GDP beat validates Wednesday's hawkish hold; the tame core PCE keeps the December meeting a question rather than a certainty.

At a Glance

The GDP/PCE Reaction Function

The following is the desk's framework for reading the session, not a forecast.

• In-line (base case): GDP prints 3.1–3.2% and core PCE 0.3% on the month (3.1% on the year), confirming strong growth with firm inflation — the combination that justified Wednesday's hawkish hold and keeps December hike odds near 83%. The 10-year holds above 5.00%, the dollar stays firm, and equities keep trading the earnings split: Alphabet's drag on the Nasdaq against Microsoft's lift and the Dow's old-economy bid. Desk judgment: this path changes little about the week's arc — the December meeting remains the main event, and the tape's battle is stock-specific, not data-driven.
• Hot (GDP above ~3.5% or core PCE 0.4%+): A hot growth or inflation print hardens the December hike case toward a near-certainty and pushes the 10-year further above 5.00%. Growth leaders take the hit first — Nasdaq futures are already down 1.2% on Alphabet, and a hot print compounds that pressure — while crude's overnight fade reverses and the dollar tests the October highs. Desk judgment: the combination that most threatens the S&P's three-day repair: it reframes Wednesday's hold as a pause on the way to another hike, not as patience.
• Cool (GDP below ~2.8% or core PCE 0.2% or less): A soft growth or inflation print pulls December hike pricing back from ~83% toward a coin flip, yields ease back under 5.00%, and the dollar gives back its overnight firmness. Rate-sensitive names — small caps and the broader equal-weight market — get room to follow Microsoft's premarket strength higher, though Alphabet's 10% premarket drop keeps the Nasdaq capped regardless. Desk judgment: the cleanest relief path for the tape, but it would take the GDP Price Index confirming disinflation, not just a headline miss on growth, to fully unlock it.

Overnight Headlines

• The AI trade gets its report card, and the grades are split: Microsoft beat analyst expectations for revenue and earnings in its fiscal first quarter, with Azure cloud growth and capital spending below expectations supporting a roughly 4% premarket gain. Alphabet missed on both adjusted earnings per share and revenue, reported negative free cash flow of $9.07 billion, and maintained its full-year capital-expenditure forecast at $195–205 billion even as its cloud business roughly doubled; shares fell more than 10% premarket. The message from the overnight tape is blunt: the market is no longer paying for AI ambition on trust — it wants the spending to turn into cash. Wednesday's regular session had gone the other way, with Micron up nearly 6% and Broadcom up more than 2% on strong chip demand, and Oracle up about 11% after saying it would restrict additional fundraising to $20 billion through fiscal 2030.
• The Fed holds, and the December hike trade gets louder: The FOMC kept rates at 3.75–4.00% in a 10–2 vote, with two policymakers voting for an immediate hike, and the press conference kept December firmly in play — markets now price an ~83% chance of an increase at the December 8–9 meeting. The 10-year yield climbed roughly 5 basis points to ~5.04%, gold eased to ~$4,028 on the firmer rate path, and the dollar index held near 102.25. With headline PCE expected at 3.6% year over year and core at 3.1%, the data this morning either validates or reprices that entire December repricing in one shot.
• Asia mixed, Europe's central-bank double bill, oil's round trip: Japan's Nikkei rose about 1.1% on chip strength while South Korea's Kospi fell roughly 1–2% and Shanghai slipped ~0.7%; the ECB decides at ~9:15 AM ET with a hold at 2.50% expected and the December-hike signal the focus of the press conference. Crude faded overnight — WTI down ~1.5% to ~$101.26 — after the Wall Street Journal reported the U.S. vice president sent a letter to Iran's security council secretary seeking to revive peace talks, reversing part of Wednesday's geopolitical premium from reported attacks on Saudi infrastructure. Gold and silver both eased on the stronger dollar, while Bitcoin slipped below ~$80,200.
• A heavyweight earnings double header frames the data: Before the open, Caterpillar, Eli Lilly, Mastercard, and Merck report; after the close, Amazon, Intel, Coinbase, and Starbucks headline. With the 7-year Treasury note auction at 1:00 PM ET and the EIA natural-gas report at 10:30 AM ET, the session has stock-specific and rate-market catalysts well beyond the 8:30 AM ET data.

What to Watch at the Open

1. Whether the GDP and PCE prints agree with each other. The desk's scenarios assume the growth and inflation signals point the same way; the tricky version is a split — hot GDP with soft core PCE, or weak growth with a hot price index — which leaves the December hike odds whipsawing and the 10-year stuck near 5.00% with no clear direction. A clean pair of prints moves the tape; a conflicted pair moves it twice.
2. Nasdaq breadth beyond the two mega-caps. Alphabet's 10% premarket drop is the day's biggest single-stock risk, but the question for the index is whether the rest of big tech holds its bids — Microsoft's premarket gain and Wednesday's chip strength argue the AI trade still has buyers at the right price. If the whole Nasdaq complex rolls over with Alphabet, the fade is about AI spending, not one quarter.
3. The ECB's December signal at 9:45 AM ET. With a hold at 2.50% fully expected, the trade is in the press conference: whether the governing council validates the roughly 84%-priced December hike after September inflation hit 3.8%. A hawkish ECB alongside a hot U.S. print would be the full tightening-tone day; a dovish one would give the morning's data a softer global backdrop.
4. Crude's overnight fade and the premarket Dow bid. WTI back under ~$101.50 eases the inflation side of the ledger just ahead of the PCE print, and Dow futures pointing half a percent higher show where the tape wants to rotate when tech wobbles. If oil reclaims its overnight losses into the data, the energy premium re-enters the inflation debate minutes before the release.

The Structural Read

Thursday is the week's data climax: GDP, PCE, jobless claims, and the ECB decision all before 10:00 AM ET, with the Bank of Japan and the Employment Cost Index arriving Friday. The structural anchors from Wednesday's FOMC are unchanged — rates held at 3.75–4.00% with December priced at ~83% — but those anchors were built on September's inflation and October's growth, and the next two mornings' releases rewrite the inputs. Inflation has come down dramatically from the 2022 highs even with crude back above $101 and headline PCE near 3.6%, and the market's bias toward treating pullbacks as rotations has held for three straight closes. Desk judgment: the overnight AI-earnings verdict is the deeper read on the tape's health than any single data point this morning — the desk's standing bias is that investors are rotating toward proven cash generation, and this morning's GDP and PCE prints decide whether that rotation gets a rate-path tailwind or headwind. The risk to the read is a hot pair of prints landing on a tape already paying above 5.00% for the 10-year, which turns a stock-specific story into a macro one.

Bottom line: A data-day triple header — Q3 GDP, September PCE, and jobless claims at 8:30 AM ET, then the ECB at ~9:15 AM ET — opens with Nasdaq futures down ~1.2% on Alphabet's earnings miss and Microsoft's beat lifting the premarket elsewhere. Watch the GDP/PCE pair for whether it validates Wednesday's hawkish hold, the ECB press conference for the European half of the December-hike trade, and whether Alphabet's drag stays stock-specific or drags the whole AI complex with it.
