http://www.theregister.co.uk/2016/08/11/exodus_intelligence_500k_bounty/ Apple offers up to $200K "for major flaws in iOS". Exodus offers up to $500K for the same. Probably there is a marketing catch in "up to". Likely on the black market prices are higher. IIRC Some leaked Hacking Team emails suggest "exploit brokers" are reselling sploits for $100K per sploit (and possibly higher).
