$1 trillion for Musk on Forbes after SpaceX shares jump

$1 trillion: Forbes put Elon Musk's net worth there on Oct. 5, up $30.6 billion since Oct. 2, after SpaceX shares jumped. My take: it's mostly a higher paper value on his large, hard-to-sell private holding, not cash. Different trackers use different math, so read $1 trillion as rough.
