Details
September CPI rose 3.7% year over year, with core inflation at 2.6%, hotter than expected
Headline CPI rose 0.6% month over month; the upside surprise triggered the day's sell-off.
Gasoline prices jumped 9.1% in September, tied to Middle East conflict energy prices
Gasoline accounted for over half of the monthly all-items increase.
Nasdaq fell about 2% and the S&P 500 fell more than 1% on the CPI report
Tech stocks were hit as investors rotated toward defensives such as healthcare and consumer staples.
CME FedWatch odds of a 25bp October rate hike rose to about 37%
Up from 22% on Tuesday and about 18% a week earlier.
AI infrastructure stocks including GE Vernova and Eaton were among the day's laggards
These names are tied to the data-center buildout and sensitive to the cost of capital.
SOXX semiconductor ETF fell 4%, its seventh straight losing session
The streak has produced a decline of nearly 12%, the worst since May 2025.
Broadcom CEO Hock Tan warned Monday that access to capital could be the industry's next constraint
He spoke at a conference in Singapore; higher rates would make a financing constraint more acute.
Anthropic is expected to share updated financials with institutional investors on Wednesday
No figures have leaked; the commentators suspect disappointment, which is speculation.
Stat = data point, Context = background, Market Impact = market/price effect, Industry Update = business signal, Financials = company finances
What This Means
A hotter inflation reading raised the odds that the Fed tightens again, and capital-hungry AI infrastructure stocks sold off. The chip sector's seven-day slide shows how exposed the AI buildout trade is to interest rates and financing costs. The suggestion that Anthropic's financials will disappoint is commentators' conjecture, not reported fact.
