Just seven companies are expected to generate nearly $2.8 trillion in net profits over the next three years. That's more than the entire economy of Italy. But the real story isn't just the total number. It's how those profits are distributed. $AMZN is expected to generate the highest revenue in the group: $2.8 trillion. And yet, its net profit is projected to reach only $345 billion. Meanwhile, $NVDAB , with roughly half the revenue, is expected to generate $660 billion in profits. Nearly twice Amazon's profits, with half the revenue. The secret comes down to one word: Margin. NVIDIA's profit margin is close to 55% of every dollar it generates. Amazon's is around 12%. The companies selling the AI infrastructure keep the money. The companies building on top of it distribute much more of that revenue across their costs. And at the bottom of the list, there's an even bigger surprise. $TSLAB is expected to generate just $20 billion over the entire three-year period. That's only 3% of NVIDIA's projected profits over the same timeframe. Two companies carrying the same “Magnificent Seven” label. Yet a 33x difference in projected profits separates them. The market still puts them in the same basket. But the numbers suggest the group split a long time ago: Money-printing machines at the top. Growth stories still waiting to prove themselves at the bottom. So here's the question: Do you buy the label or do you buy the margin?
