No but being rich does mean one can hire a lot of intelligent people to figure it out for them. A LOT.
The thing is, if someone figures out something against aging, you can bet it will be made incredibly expensive. After all, the planet will have a massive problem if everyone starts using it. Basically every problem we have on this world would increase massively, from global warming to housing, energy, pollution, traffic.
So it will be limited to the few and in our society that means the most wealthy (not that I agree with that but it is what it is).
So they would probably keep it secret and expensive, but they'd also be very motivated to invest in it because it would be insanely profitable. And they would benefit personally by living longer obviously. I'm sure those people with hundreds of billions in the bank think about these things.
I'm pretty sure someone like Elon Musk would eventually invest in that. Right now he's probably a bit too young to worry about ageing. But he's someone who believes in technology shaping the future of humanity. And he's got the money to try.
