I don't think consolidation is the issue here, so anti-trust doesn't make a lot of sense. There are at least five major US companies strongly competing with each other. The issue is that total investment has gone far beyond expected revenue because no one is far ahead, everyone is bidding against each other for chips/power, and competition is driving down token price. Ironically, consolidation would fix this because a single winner would be able to charge monopoly prices. Anti-anti-trust. :-)
