Two Sigma and Renaissance (albeit not Medallion) primarily invest outside capital.

Renaissance does take outside capital, but their primary business is Medallion. The outside capital is just a way to make a bit more by trading on their reputation.

Two Sigma does generate a bit more revenue from outside capital than Renaissance, but it is my understanding that the heart of their business is still prop trading. But I don't know that for certain.
