Can someone explain to me these billions and trillions being invested AI.

Can someone explain to me these billions and trillions being invested in Data Centres and cloud centres and AI by Google, Oracle, etc where are funds going. I mean if a company is going negative, another must be going positive?

I mean the money is not vanishing in air. I understand these are long term investments but then the money must be going somewhere and someone or some companies just be benefiting in the short term?
