Social media company Reddit has revealed a few details about its use of cloud infrastructure in a Securities and Exchange Commission (SEC) filing.

In its IPO prospectus, the company disclosed that it primarily uses Amazon Web Services (AWS) and Google Cloud Platform to run its services in its IPO prospectus.

As part of that filing to go public, Reddit also revealed that it had entered into non-cancellable purchase obligations with the two cloud providers to spend at least $385 million through September 2026 on their services.

It entered into that purchase agreement last year, and met previous minimum purchase commitments for 2022 and 2023.

"As Redditors generate more content, we may be required to expand and adapt our technology and infrastructure to continue to reliably store, serve, and analyze this content," the filing notes. "It may become increasingly difficult to maintain and improve the performance of our products and services, especially during peak usage times, as our products and services become more complex and our traffic increases.

"In addition, because our cloud service infrastructure is run on [cloud service providers], we cannot guarantee that we will be able to expand our infrastructure to meet demand in a timely manner, or on favorable economic terms. This is particularly challenging with regard to increasing international traffic demands."

The filing also makes passing mention of Reddit's own infrastructure and the "cost to acquire additional servers and networking equipment," but does not disclose specifics.

The company also uses Oracle Data Cloud for its advertising platform, while Tencent Cloud Europe owns more than 10 percent of the company.

Reddit said it made $804m in annual sales in 2023, up 20 percent over the prior year. It reported a net loss of $90.8m, an improvement over the $158.6m loss it suffered the year before.
