Memory and storage maker Kingston remain on Forbes’ list of America’s Top Private Companies for 2025, this time placing 28th, making a one-place improvement over 2024. The company earned $14.4 billion in revenue for the past year, which is a small improvement over 2024’s $14.0bn.
Kingston Places 28th On Forbes’ List

Notably, Kingston ranks first place under “Technology Hardware & Equipment” category, being one of the only two entries in the top 200 the most valuable of its kind while remaining privately-owned (meaning no presence in the stock market). The company says it has maintained its longstanding leadership as third-party DRAM supplier and SSD shipments spanning over two decades, which contributed to its strong presence in America’s private sector.
“This Forbes recognition, along with our ‘Built on Commitment’ philosophy, marks Kingston’s dedication and long-term vision: expand our product offerings, strengthen global partnerships, and continue setting industry benchmarks for performance and reliability,” the company said in its press statement.
Fun fact, OpenAI made it into the list for the first time, placing at just 155th, despite huge amounts of cash changing hands through the company lately. It’s a good reminder to tell you that OpenAI has only just become a for-profit business, so its numbers look relatively small. Meanwhile, Valve is placed at 120th – a big jump from the previous year’s 139th place. Previous entrants of this list, including X (Twitter) and Bose, are absent this time around.
