Congress has reached a deal to raise the federal debt ceiling, news that was well-received on Wall Street. The bill now heads to the desk of President Joe Biden, which raises the odds of the government avoiding a potentially catastrophic default. The good news from Washington, D.C., along with a stronger-than-expected jobs report, gave stocks a boost at the tail-end of the trading week. 

Telecom stocks dropped on Friday after Bloomberg reported that Amazon is in talks with wireless carriers to launch its own mobile service for Prime members. Amazon is said to be in talks with Verizon, T-Mobile, and Dish Network to potentially resell their mobile services to Prime members at a lower cost and even free in some cases. The report comes as Amazon tries to attract more members to its subscription service. However, it could take months for the companies to seal a deal. This wouldn't be the first time Amazon attempted to get into mobile. The company in 2014 launched its Fire Phone, which it scrapped a year later.

Just weeks after a massive rally, shares of Nvidia rose another 4 percent this week, pushing the chipmaker's market cap past the $1 trillion mark. The company is riding a wave of enthusiasm around the rise of artificial intelligence, and advanced semiconductor manufacturers are positioning themselves to benefit from increased adoption of the technology. Nvidia has also continued to boost investor expectations with a steady clip of announcements around new products and services. The stock was up nearly 4 percent this week.

Another beneficiary of the AI boom has been C3.ai, which provides AI-based solutions to businesses. But now the company is facing pressure from a short-seller who is accusing C3 of inflating margins, engaging in "aggressive accounting," and for an overall lack of transparency. Billionaire CEO Tom Siebel is pushing back against the allegations, saying in a statement that it "appears to be a highly creative and transparent attempt by a self-acclaimed short seller to short the stock, publish an inflammatory letter to move the stock price downward, then cover the short and pocket the profits." The stock ended the day Friday down 7 percent but still rose 12 percent for the week.
