We still dont know what they did or didnt do. I doubt they "put all their eggs in one basket". No bank is this stupid at risk management, and from everything I read on SVB it was trusted well run bank. They had a lot in treasury bonds, which are locked up for 5 years, or they can sell at a loss (a bigger loss since interest rates keeps climbing). They were trying to raise funds to not sell at a loss and wanted to keep to maturity, this spooked big shot VCs with a huge twitter following, and then caused everyone to want their money back. It was a self fulling prophecy.
As far as we know at this moment (not much), SVB did what every single financial instution is doing and expected to be doing. If this happened to JPM, they would also be in the same situation. The only benefit JPM has is that they have a 'better' reputation and may not have caused such a contagion of panic.
