The Digital Asset Market Clarity Act, or CLARITY Act, is moving toward a key Senate markup expected in January, according to White House artificial intelligence and crypto advisor David Sacks. The bipartisan bill, already passed by the House in July, aims to define which digital assets are securities or commodities and clarify the roles of U.S. regulators in overseeing crypto markets. Its progress follows earlier delays linked to a 43-day government shutdown and will require navigating a closely divided Senate before potentially reaching President Donald Trump for signature.

As President Donald Trump's second term enters its first year, the Senate has confirmed Mike Selig to lead the CFTC and Travis Hill to head the FDIC, filling long-standing vacancies at two pivotal financial watchdogs.

The appointments also cement a more permissive stance on crypto banking at the FDIC while positioning the CFTC to shape rules for spot trading and stablecoins.
