The U.S. Senate has confirmed Waller as the new Federal Reserve Chair, succeeding Powell, with a vote of 54-45. On Waller's first day, the S&P 500 reached a high of 7,501 before retreating, while Bitcoin fell below $82,000, stabilizing above $77,000. Market analyst Tom Lee anticipates a potential 15% to 20% market pullback during the initial phase of Waller's tenure but remains optimistic, projecting the S&P 500 to hit 7,700 by the end of 2026.
