We will show how to construct hyperkähler manifolds of O'Grady 10 type out of smooth cubic fourfolds. Applications to classical algebraic geometry questions on intermediate jacobian fibrations of families of cubic threefolds, and quintic elliptic curves on cubic fourfolds will be explained. This is based on joint work with Chunyi Li and Laura Pertusi. Meeting passcode: MSU ALG
