How does a big lottery winner cash his huge check risk-free?
You cant! There is the risk that between the time you get the check and the time you get to the bank that you will be murdered, have a heart attack, stroke, or aneurysm too.  And they are probably more likely than the bank going out of business between the time you deposit the money and get access to it. Prior to accepting the check I would do the following: Get a lawyer that specializes in finance and tax law.  There are some steps you can take to minimize your tax exposure.  There is little you can do about the immediate tax on the winnings but there are things you can do to maximize the return of your money.    You will want to do what you can to protect that money for yourself and your family.  Also create or revise your will.  This is a lot of money and if something happens to you people from your family and "friends" will come out of the woodwork trying to claim your money.  Make sure your money goes where you want it to in the event something happens to you. Get a financial planner.  This money can either make you or break you.  If you plan for success you will succeed.  If you trust yourself to make good decisions with out a plan, in a few years you will be broke and wondering what happened to your money. Even at 1% at 20million dollars that is 200k a year in interest... a pretty good income by itself.  You do not have to save every penny but you can plan for a nice lifestyle that will last, if you plan and stick to your plan. Do research and know what bank you are going to deposit the money in.  Talk to the bank let them know of your plans so they can be ready for it.  It is not every day that they get a 20 million dollar deposit.  They will need to make plans to handle it.  If you are going to spread the money out among several banks they can prepare for that too. When choosing that bank I would look for one where their holdings are significantly more than you are depositing.  I would not really go with one of the banks that was rescued.  They have already shown that they can not handle large sums of money and assuming they will not screw it up with my money is not something I would be comfortable with.  There were some nice sized banks that did not need a bail out.  I would choose one of them.
