<p>Elon Musk's merger of SpaceX and xAI has led to a valuation of SpaceX at $1.25 trillion, closely approaching Tesla's $1.58 trillion market cap. Musk's wealth has surged to over $852 billion, with SpaceX now representing a significant portion of it. Tesla faces challenges, including a 16% drop in vehicle deliveries and a 3% revenue decline in 2025, prompting a shift in focus to Robotaxi and Optimus projects. The merger raises concerns about funding xAI's infrastructure and potential legal issues, as xAI is under investigation in multiple jurisdictions.</p>

- Elon Musk's merger of SpaceX with his AI venture xAI marks a significant shift in his corporate focus, with Tesla's market valuation now substantially impacted.  
- Despite Tesla's declining performance and increased competition, SpaceX remains strong, generating significant revenue and profits, while pursuing a potential IPO.  
- However, the merger introduces regulatory risks and funding needs for xAI that could complicate SpaceX's financial standing, raising concerns among investors about Musk's divided attention.
