nvidia's money either comes from equity, or from debt. This means this money is "created" not from nothing, but from future commitments (ala, debt repayments, or promise of profits), which is not the same as what comes out of the Fed.
The Fed printing has no backing behind it - it is definitely inflationary if they do it. Investment from nvidia (or any other company) "creating money" may be productive enough to completely offset their inflationary effects - after all, the company investing demands returns from their investments, and so will only invest in things they expect to return much higher than the cost of interest (or cost of capital).
Therefore, you cannot compare Fed printing money to company investing money.
