One of the bills (The "Ending Platform Monopolies Act") specifically targets companies with $600 billion market cap (AAFG), and misses Walmart by around $200 billion (it currently has market cap of less than $400 billion). It will be really funny if Walmart stock rises due to Amazon being split, and hits the $600 billion.
Companies with strong financial engineering competencies will have no problem working around these limits.
Instead of the government picking winners and losers, how can the rules be structured to level the playing field for everyone?
