Quantum computing is advancing slowly but surely towards being able to factor large numbers. Much of modern encryption relies on large numbers being unfactorable. Research is being done into quantum-safe encryption, but it hasn't really caught on.

If quantum computing gets to the point where people start being scared of it, and there's a rush to transition to safer encryption, this market resolves YES. If everyone acts wisely and updates their encryption far in advance of a quantum computer that can break it, this market resolves NO.

Yes, this is very subjective. I won't bet.
