Five trading days, four scheduled catalysts, and a Fed chair who has been in the job three months. That is the setup heading into the week of August 24-28, and the calendar is unusually stacked even by this year's standard.
What's the single biggest event to watch this week?
Kevin Warsh delivers his first speech as Fed chair at the Jackson Hole Economic Policy Symposium, hosted by the Federal Reserve Bank of Kansas City from Thursday through Saturday, August 27-29. His keynote lands Friday. Warsh took over from Jerome Powell in May 2026, and this is the first time markets get an unscripted read on how he frames policy outside a press conference.
Every Jackson Hole since 2020 has moved yields within minutes of the chair's remarks. What makes this one different is that nobody has a prior speech from this chair to compare it against. Powell's framing habits were priced in after a decade on the committee. Warsh's are not, which is exactly why positioning tends to go quiet into a week like this: traders wait for the keynote's tone before committing size either direction.
What does Wednesday's economic data actually tell the Fed?
Core PCE and the second GDP estimate both print Wednesday, August 26, typically around 8:30 AM ET alongside durable goods orders. Core PCE is the Fed's preferred inflation gauge specifically because it strips out food and energy, the two categories most likely to spike from a one-off shock rather than a change in underlying price pressure.
The catch is the lag. Wednesday's Core PCE print describes July spending, already three weeks stale by the time it lands. GDP's second estimate for the prior quarter carries a similar lag. Neither number is a live read on where the economy stands today, but both are exactly what the Federal Open Market Committee will lean on heading into the September 16 meeting, because it is the most complete data the committee has.
What is the Fed actually pricing for September, and is it a cut?
No. As of August 23, CME FedWatch-tracked pricing for the September 16 meeting runs roughly 60% for a hold at the current 3.50%-3.75% target range and close to 40% for a hike to 3.75%-4.00%. That is a meaningfully different split than most of 2025, when the market spent the year pricing cuts.
The Federal Reserve has held the funds rate at 3.50%-3.75% since December, reconfirmed at the June meeting, Warsh's first as chair. The reason the hike odds are live at all: inflation prints have kept coming in hotter than forecast through the summer, while the labor market has not softened enough to give the committee cover to ease. Rate hikes typically follow that kind of data pattern rather than lead it, which is why this week's prints carry more weight than a routine data day would.
Why does Nvidia's earnings report matter beyond one stock?
Nvidia reports fiscal Q2 2027 results Wednesday, August 26, after the close, with Wall Street modeling roughly $93-95 billion in revenue and adjusted earnings per share near $0.65-0.68, on continued AI accelerator demand and the ongoing Blackwell architecture ramp, per MarketBeat's earnings calendar. That revenue estimate would represent close to 80% year-over-year growth from the same quarter last year.
Nvidia's print has functioned as a bellwether for the entire AI capital-spending trade for several quarters running, not just its own share price. A guide that disappoints on data center demand or gross margin gets read as a signal about hyperscaler capex broadly, on the same day markets are also digesting Core PCE and GDP. Three macro-scale inputs landing within hours of each other is not a coincidence traders get often.
What broke last week that sets up this week?
The S&P 500 closed Friday, August 21, at 7,674.37, up 0.4% on the day but still down for the week after a bond selloff pressured risk assets, with technology shedding more than 3% over five sessions. The 10-year Treasury yield rose to 4.74% the same session. The VIX closed at 15.13, down 5.5% on Friday and still inside a normal-risk range even after the week's volatility.
Rising long-end yields, not any single headline, did most of the damage to equities last week. That mechanism does not reset over a weekend. Watch the 10-year into Wednesday's GDP and PCE prints specifically, since a hotter number that pushes yields higher again would extend the same pressure that already cost the major indexes a losing week.
