Investors on edge as debt ceiling uncertainty weighs on Wall Street and global markets.

Stock futures for Dow Jones, S&P 500, and Nasdaq 100 dipped slightly on Sunday evening as traders monitored the negotiations over the U.S. debt ceiling. President Joe Biden and House Speaker Kevin McCarthy are set to meet on Monday to continue negotiations. Treasury Secretary Janet Yellen has warned that the U.S. could default on its debt as early as June 1. Despite the uncertainty, the market has continued to rise, led by tech stocks. Bank of America strategist Savita Subramanian hiked her year-end target for the S&P 500 to 4,300 from 4,000, saying that stocks were not overvalued. The upcoming week has a relatively light slate of economic data, highlighted by a second reading for first-quarter GDP on Thursday and the personal consumption expenditures inflation gauge on Friday.
