Elon Musk's SpaceXAI is launching Grok 4.5, its smartest model yet, and its first release since going public and acquiring the AI coding startup Cursor.

Wall Street's sell-side analysts published a slew of bullish reports on SpaceX Tuesday, while cautioning that years of massive investments will be needed to bring Elon Musk's vision for the company to fruition.

South Korea's other massive memory chipmaker, SK Hynix, plans to sell $28 billion in stock in the U.S. later this week, even as waves of volatility batter the chip shares.
