[Marvel and DC universes] What could cause Wayne Enterprises or Stark Industries to go bankrupt?

Both companies have seemingly limitless amounts of cash. What could possibly cause it all to dry up?

Wayne Enterprises could, in most circumstances, outright buy most iterations of Stark's companies without much (if any) fuss. Between Wayne Enterprises and LexCorp, the two holding companies make an absurd amount of the GDP of the US - upwards of *half* if some claims are to be believed. Remember that WayneTech is only one small part of what Wayne Enterprises encompasses.

Stark, meanwhile, has gone bankrupt or been bought out multiple times. His current company (Stark Unlimited) is something like the sixth company he's had and built up. It wouldn't take nearly as much for his companies to go bankrupt.
