Because of its superior technology and extraordinarily profitable business model, Nvidia has become the central bank of the artificial intelligence revolution. Just as the Federal Reserve determines monetary policy for the United States and, in many cases, strongly influences monetary policy across the world, Nvidia influences almost every aspect of the AI revolution. This is one reason so many eyes will be upon the company as it unveils its latest earnings results on Wednesday.Nvidia generates extraordinarily high profit margins. Its gross margin, the difference between the cost of producing its products and the revenue it receives from selling them, is around 75%. In practical terms, that means Nvidia generates extraordinary amounts of free cash flow. For its current fiscal year, which ends in January 2027, Nvidia is projected to produce about $150 billion in free cash flow. Nvidia uses that cash to influence nearly every part of the global AI revolution, including compute capacity, which has become the currency of the revolution.Over the past three years, Nvidia has increased its earnings and free cash flow at an astounding rate. Net profit has risen from about $30 billion in the fiscal year that ended in January 2024 to a projected $240 billion for the fiscal year ending in January 2027. The company devotes a good chunk of that to research and development. This fiscal year, Nvidia will spend about $25 billion on R&D. But large amounts of capital will also be used to help companies finance purchases of Nvidia’s most advanced accelerated computing platforms. This is a form of circular financing, but it is not fundamentally different from the financing arms operated by vehicle manufacturers or home builders.
