Dow Jumps 509 Points, VIX Craters as Hot CPI Sends Hike Odds to 90%

Wall Street shrugged off a hotter-than-expected inflation report Friday and rallied hard, snapping the week's four-day losing streak. August core CPI rose 0.3% month-over-month, ahead of the 0.2% economists expected, pushing the odds of a Federal Reserve rate hike at next week's meeting to roughly 90% from about 70% a day earlier. Stocks rose anyway: the Dow gained 508.71 points, or 0.98%, to 52,572.81, while the S&P 500 and Nasdaq both climbed nearly 1%.

The disconnect between hawkish data and a bullish tape makes more sense once you look under the hood. Semiconductor stocks led the rally by a wide margin, extending the lift from Oracle's blowout earnings reported after Thursday's close. The VIX, meanwhile, fell more than 11% — a sign that the week's dominant source of uncertainty, today's CPI report, passed without producing a bigger shock, freeing the market to trade on the Oracle-driven AI narrative instead.

The numbers, by the close

Sector and asset ETF scoreboard

All figures below are confirmed closing prices and changes from the prior close.

Today's scoreboard was almost uniformly green — a sharp reversal from Thursday's almost uniformly red one. The standout is semiconductors: SOXX and SMH topped the board, both extending the lift from Oracle's earnings the night before, while energy (XLE) posted a small gain despite crude oil itself falling on the day, another reminder that the sector ETF and the underlying commodity aren't always moving together this week.

Market temperature and volatility

A double-digit percentage drop in the VIX alongside a broad equity rally is a classic "uncertainty resolved" pattern: the data came in hot enough to seal the case for a hike, but not so hot as to suggest inflation is spiraling out of control, and markets had already been bracing for a hawkish outcome after Thursday's PPI report. With the CPI event now behind it, the market appears to have redirected its attention toward the more unambiguously bullish Oracle earnings story.

Rates, dollar, gold, and crypto

Treasury yields sent a genuinely mixed signal today. The 2-year yield, which tracks Fed policy expectations most closely, rose modestly to 4.572% — it had spiked nearly 11 basis points intraday before paring the move — a direct reaction to the jump in rate-hike odds. The 10-year yield, by contrast, actually fell to 4.91%, retreating after briefly approaching the 5.00% threshold earlier this week. That's a sign long-end investors may see today's data as confirming a near-term hike is priced correctly, without necessarily extending the higher-for-longer narrative further out the curve.

Gold slipped modestly, bitcoin ticked higher, and ether posted the day's standout crypto move.

Sectors: leaders and laggards

Today's leadership pattern was almost the mirror image of Thursday's: instead of a broad, indiscriminate selloff with semiconductors hit hardest, today brought a broad rally with semiconductors leading by the widest margin. The read-through from Oracle's earnings dominated sector positioning.

The day's market-moving stories

1. August core CPI comes in hotter than expected

Core CPI, which excludes food and energy, rose 0.3% month-over-month in August, ahead of the 0.2% economists expected. Headline CPI matched forecasts at 0.4% month-over-month and 3.4% year-over-year. The core beat, small as it was, was enough to meaningfully shift the market's read on next week's Fed decision.

2. Fed rate-hike odds jump to 90%

CME FedWatch data showed the probability of a 25-basis-point hike at the Fed's September 16 meeting climbing to roughly 90%, up from about 70-72% just a day earlier. "The upside surprise to core CPI in August means the Fed looks set to hike next week," said Capital Economics' Stephen Brown, a view echoed across Wall Street economists following the report.

3. A wireless-phone price surge drove much of the core beat

A 5.9% jump in wireless telephone service prices alone added roughly a tenth of a percentage point to the core CPI reading, according to Bureau of Labor Statistics data. It's a reminder that a single volatile category can meaningfully swing a headline inflation print that then drives major market repricing.

4. Economists: one hike likely won't end the tightening cycle

Several economists said today's data points to more than a single, one-and-done hike. Capital Economics is projecting an additional quarter-point increase in December and another in March 2027, while EY-Parthenon changed its call from a hold to a hike for next week specifically because of today's core print. Fed Chairman Kevin Warsh's Jackson Hole remarks last month — that inflation remains too high and policy isn't yet restrictive outside housing — look more prescient in light of today's data.

5. The 10-year yield retreats even as the 2-year rises

The 2-year yield, which tracks Fed expectations most closely, rose to 4.572% on the hike-odds repricing, having spiked nearly 11 basis points intraday before paring back. The 10-year yield moved the opposite direction, falling to 4.91% after flirting with the 5.00% level earlier this week — a curve dynamic that suggests near-term policy expectations and longer-run growth/inflation expectations are telling somewhat different stories right now.

6. Oracle sells off despite beating — even as it powers a broader AI-stock rally

In a genuine "sell the news" twist, Oracle shares themselves fell 1.74% to $150.28, down $2.66, a day after beating decisively on both EPS and revenue and posting 121% growth in cloud infrastructure revenue. Yet the print still rippled through the broader AI-adjacent trade: semiconductor ETFs were the session's clearest beneficiaries, with SOXX and SMH both posting their best single-day gains of the week, even as the stock that sparked the enthusiasm gave back ground. Oracle was little changed after hours, up just 0.15% to $150.06.

7. The VIX posts its sharpest drop of the week

The VIX fell more than 11% to 15.84, its largest one-day percentage move of the week, as the market's central source of near-term uncertainty — today's CPI report — resolved without a larger surprise. Combined with the Oracle-driven AI enthusiasm, that cleared the way for a broad-based rally.

8. Oil eases back from the week's highs

Crude oil fell 1.79% to $100.65, pulling back after surging more than 7% earlier in the week on the U.S.-Iran conflict. The pullback offered some relief on the inflation front even as the underlying geopolitical situation remains unresolved.

9. Ether sharply outperforms bitcoin

Ether jumped 4.15% to $2,538.36, far outpacing bitcoin's 0.15% gain to $77,358.29. No single catalyst was confirmed for the divergence, but it's a notable break from the two assets' recent tendency to move together.

10. The memory and semiconductor complex broadly stabilizes

A day after DeepSeek's efficiency claims dragged on memory and storage names, the broader semiconductor trade rebounded sharply today, led by Oracle's earnings-driven momentum. It's a reminder that sentiment-driven selloffs in this sector have tended to prove short-lived this cycle, though individual memory and storage names' recovery wasn't independently confirmed for today's session.

Movers below the headlines

The clearest single-stock story remains Oracle, still digesting Thursday night's earnings beat:

Earnings spotlight

Kroger reported before today's open, while the dominant story from Oracle's Thursday-night print continued to drive sector-wide moves:

Kroger: the details

The headline tension in Kroger's quarter is the gap between a lowered sales outlook and resilient profitability. Management cut full-year identical-sales-without-fuel guidance to 0.2%-0.8% (from 1%-2%), and said the Inflation Reduction Act's drag on pharmacy sales should widen to roughly 150 basis points in Q4 as new high-cost drugs, including GLP-1s, join the formulary — but explicitly said that headwind carries no expected profit impact in Q4 or 2027. On the call, management repeatedly framed the softer topline as a function of a pressured consumer (citing reduced SNAP benefits, gasoline over $4, and softer confidence) rather than a Kroger-specific issue, pointing to share gains against Circana's broader industry benchmark as evidence the business is still outperforming a weak backdrop.

Elsewhere, Kroger highlighted continued momentum in Our Brands (Private Selection sales up more than 14%, penetration up roughly 50 basis points), a rebranded loyalty program ("Points," redeemable for fuel or groceries), and reiterated that its planned acquisition of Giant Eagle remains on track for a 2027 close pending regulatory review. On the analyst call, Bank of America's Robbie Ohmes asked about the inflation outlook specifically; management said it still expects grocery inflation to run below CPI for the balance of the year despite mounting fuel-cost pressure — a detail worth watching given today's own hot CPI print.

Oracle: still setting the tone

See Thursday's recap for the full breakdown, including guidance detail. Today's semiconductor rally shows the market embracing the broader AI-infrastructure story from the print — even though Oracle's own stock fell 1.74% to $150.28, a "sell the news" reaction distinct from the sector's enthusiasm. See the movers section above for Oracle's specific price action.

Key market & macro risks to watch

What to watch next

The takeaway

• The market decoupled from the headline inflation story today. A 90% hike-odds print would normally pressure stocks; instead, Oracle's earnings and a collapsing VIX dominated the tape.
• Leadership was narrow, not broad. Semiconductors and technology drove the gains, while small caps and equal-weight tech lagged — worth watching whether participation broadens or the rally stays concentrated.
• The Fed conversation has shifted from "will they" to "how many." With economists now debating a multi-hike cycle rather than a single move, next week's meeting and forward guidance carry outsized weight.
