Today’s business headlines span spectacle, science, scandal and dealmaking. In Washington, the Treasury is quietly preparing for the possibility of a new $250 bill bearing Donald Trump, though any such note still depends on Congress changing the law. In one of the day’s biggest corporate moves, Tilman Fertitta’s firm struck a $5.7 billion cash deal for Caesars Entertainment, a takeover that expands his casino empire and underscores continued consolidation in gaming. In South Korea, Samsung affiliates are betting $408 million on Dunamu, owner of crypto exchange Upbit, signaling how mainstream institutions are positioning for the next phase of digital-asset regulation. Meanwhile, new “BlackHoleWeather” simulations offer a reminder that investment in cutting-edge computing is reshaping astrophysics as well as industry. And in a starkly different story, former CIA officer David Rush faces allegations he stole more than $40 million in gold and cash from federal custody.
