Several U.S.-listed companies experienced notable share price movements in premarket trading on Monday, Sept. 21, 2026. The activity followed a series of company-specific announcements, media reports, and changes in analyst ratings.
Media companies Paramount Global and Warner Bros. Discovery saw their share prices increase. Paramount shares rose over 5.8%, while Warner Bros. Discovery shares were up more than 7%. The increases followed a report from The Wall Street Journal over the weekend. The report stated that Paramount and the office of California Attorney General Rob Bonta had entered into discussions regarding a settlement for a lawsuit related to the proposed merger of the two companies.
In the technology sector, Accenture shares increased by more than 6%. The movement occurred after the professional services company announced on Friday that it would partner with artificial intelligence firm Anthropic. According to a statement from Anthropic, the agreement includes plans for each company to invest at least $1 billion to expand their capabilities in AI development and application.
Conversely, shares of the pharmaceutical company Novo Nordisk declined by nearly 5%. The stock’s fall came after the Denmark-based company detailed its long-term financial and product development goals. Novo Nordisk announced its intention to launch a minimum of five drugs by 2030 and to generate more than 150 billion Danish kroner (approximately $23 billion) in risk-adjusted pipeline sales by 2035.
Cryptocurrency exchange Coinbase Global Inc. saw its shares gain more than 4%. The stock’s movement was concurrent with a rise in the price of bitcoin, which reached $85,229.44, a level not recorded since Jan. 29. The gain on Monday followed a 10% increase in Coinbase shares last week after a regulatory development related to tokenized stocks.
Shares of home furnishings company Arhaus rose nearly 3%. The move followed an upgrade of the company’s stock rating by investment firm Jefferies. An analyst note from the firm revised the rating to “buy” from “hold,” with Jefferies analyst Jonathan Matuszewski citing the company’s strategy to increase its brand awareness as a factor in the decision.
