The S&P 500 ended lower on Tuesday, with Salesforce and other software makers losing ground, while hostilities in the Middle East lifted oil prices and investors awaited inflation data that could affect the chance of an interest rate hike.
Salesforce CRM.N and Intuit INTU.O fell about 4%, while ServiceNow NOW.N lost 5%. OpenAI's launch last week of its newest model, GPT-6 Astra, reignited speculation that AI could compete with services now offered by specialized software companies.
The S&P 500 software and services index .SPLRCIS fell 1.4%, down for a second straight day.
"Astra has kind of reignited the software disruption fears and it's resumed that old trend that we got used to for a while, where semiconductor stocks and data center capex beneficiaries do well, while software stocks do poorly," said Jed Ellerbroek, portfolio manager at Argent Capital Management.
Intel INTC.O jumped 9% and Qualcomm QCOM.O rose 3.2% after striking a deal with Amazon AMZN.O to develop custom AI chips.
Traders increased bets on an interest rate hike at the U.S. Federal Reserve’s September 15-16 meeting after the Labor Department reported last week that employers added far more positions than expected in August.

S&P VALUATION DOWN FROM JUNE
The S&P 500 has gained about 12% in 2026, and it remains down about 1% from its record-high close on August 13.
The benchmark stock index is now valued at 19 times expected earnings, down from 21 in early June, according to LSEG data. That lower valuation reflects increased earnings expectations following a strong second-quarter reporting season.
Despite that increased earnings optimism, the U.S.-Israeli war with Iran has remained an overhang on equities.
Oil prices touched a six-week high on Tuesday after Iran-backed Houthis in Yemen attacked Saudi energy facilities, setting oil installations ablaze and threatening a major expansion of the six-month-old Middle East war.
Shipping traffic through the Strait of Hormuz slowed, with Iran threatening on Monday to retaliate for any new U.S. attacks.
"The conflict between the United States and Iran is beginning to look less like a temporary disruption and more like a longer-term backdrop for markets," said Jeff DerGurahian, chief investment officer at loanDepot.
The S&P 500 energy index .SPNY rose 1%, with Marathon Petroleum MPC.N up 2.4% and Occidental Petroleum OXY.N adding 1%.
