Key Points - The quantum computing industry may be approaching its gold rush era. - Nvidia, Microsoft, and Alphabet all stand to gain a lot from the growth of the space. Folksy wisdom holds that the surest way to make money during a gold rush was to sell shovels rather than swing picks. As with many emerging industries, quantum computing could be reviving that old dynamic, at least for a while, and it's no surprise why. In particular, Nvidia(NASDAQ: NVDA), Microsoft(NASDAQ: MSFT), and Alphabet (NASDAQ: GOOG)(NASDAQ: GOOGL) -- none of which earn a meaningful sum from quantum yet -- could prove to be the best upstream providers to the quantum computing industry. The whole industry could be worth as much as $4.4 billion by 2028, according to research by McKinsey, up from being worth $1 billion today. Missed Nvidia in 2009? This Rare Signal Is Flashing Again.In 2009, a "Double Down" signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same "Total Conviction" signal is flashing for a company 1/100th the size of Nvidia. Continue » Which of these three businesses is best positioned to capture a slice of that growth, not to mention whatever happens in the long run? Nvidia is already selling shovels to everyone Nvidia doesn't build a quantum chip, and it might not ever. Its CUDA-Q software runs on most public quantum processors, splitting each job between graphics processing units (GPUs) and the qubit hardware. In October 2025, it launched NVQLink, an interconnecting layer wiring those processors to its own GPUs, and 17 quantum builders and nine national labs were using its solution within weeks. Another underlying theme here is that any fault-tolerant quantum computer will need plenty of classical computing power besides qubits to decode errors, and Nvidia sells
