It's definitely possible. assets = liabilities + equity. Well, SVB equity has already been wiped out to zero, so that's money JP Morgan doesn't need to come up with to make the value of the assets (i.e their securities) equal their liabilities (their deposits). It could theoretically be worth it to JPM to buy SVB to (a) in one fell swoop take over the biggest startup-focused financial institution, and (b) calm systemic risk fears.
