US stocks were mixed on Thursday, eyeing fresh records as OpenAI (OPAI.PVT) buzz buoyed techs and blotted out the prospect of a US government shutdown with no end in sight.
The tech-heavy Nasdaq Composite (^IXIC) led the way higher, rising 0.1%. The S&P 500 (^GSPC) declined 0.1%. The Dow Jones Industrial Average (^DJI), which includes fewer tech stocks, fell 0.2%.
The S&P 500 scored a fresh all-time high on Wednesday, closing above 6,700 for the first time, as investors focused on a fall in ADP jobs numbers that cemented bets on interest-rate cuts this year.
That upbeat mood held as a wave of good news from the AI sector lifted chip stocks worldwide, with Nvidia (NVDA) rising to a record high. AMD (AMD) and SK Hynix (000660.KS, HXSCL) also gained.
OpenAI's (OPAI.PVT) valuation soared to $500 billion after an employee share sale, boosting tech rally hopes despite fears of an AI bubble. The ChatGPT maker ousted Elon Musk's SpaceX (SPAX.PVT) as the most valuable startup in the world.
Elsewhere on the tech front, shares in Alibaba (BABA, 9988.HK) stock popped after JPMorgan raised its price target by almost 45%.
Markets are setting aside the US government shutdown, which looks set to drag on at least until the end of the week. The Senate will be out Thursday in observance of Yom Kippur, making Friday the next chance to hold a vote on funding, after it rejected Republican and Democratic bills on Wednesday to trigger the stoppage.
Given that, Friday's scheduled release of the September jobs report is all but certain to be delayed. That has Wall Street looking elsewhere during the federal data blackout as Fed policymakers have indicated cracks in the labor market will loom large in their October rate decision.
Private data from the firm Challenger, Gray & Christmas released Thursday found hiring plans at their lowest level since 2009, even as layoffs fell. The report provided more evidence of the softening “low hire, low fire” labor market after Wednesday's ADP report. Investors remain near-unanimous on bets for a cut at the Fed's next meeting.
