-- Stocks wobbled on Thursday as Nvidia's (NASDAQ:) outlook lifted tech stocks despite worries that there still was no resolution to the ongoing debt ceiling standoff.

Nvidia is projecting a record quarter because of surging demand for chips that help power artificial intelligence technology, especially around generative chatbots that have caught the public's attention in the last few months. Tech giants from Microsoft (NASDAQ:) to Amazon.com (NASDAQ:) and Alphabet's (NASDAQ:) Google are driving demand for the chips, as are cloud services providers.

The positive outlook is lifting shares of other chip makers, which are also seen benefiting from the trend at varying degrees.

The enthusiasm is drowning out fears about a possible government default if the debt ceiling issue isn't resolved in the next week. Biden administration officials have warned that Congress has until June 1 or thereabouts to raise or suspend the debt ceiling before it runs out of options. But negotiators are still trying to hammer out details on spending levels with Congress set to break for the long holiday weekend.
