MARA Holdings Inc. shares traded higher Monday as Bitcoin moved above $85,000, extending a broader rally across digital-asset markets. The stock gained 4.53% to $13.84 in premarket trading, according to Benzinga Pro data. Momentum followed sustained gains over the weekend and regulatory developments late last week. After the Clarity Act failed to advance in the U.S. Senate, the Commodity Futures Trading Commission (U.S. derivatives regulator) and the Securities and Exchange Commission (U.S. securities regulator) introduced proposals on September 17 aimed at creating a formal oversight framework for crypto-asset transactions. As a cryptocurrency miner, MARA uses computational power to secure the network and receive block rewards. Because expenses including electricity, facility maintenance and hardware depreciation are relatively fixed in fiat currency, higher Bitcoin prices can expand the margin on each newly mined coin. The source also referenced gains in S&P 500, Nasdaq 100 and Dow Jones futures following a fresh warning from Trump to Iran.
