What happened
The Information reported on August 25, 2026 that ClickHouse's annual recurring revenue (ARR) had passed $350 million. Dealroom's summary of the report said the figure came from a person close to the company and was up 40% since May. The number was attributed to that unnamed source, and the sources read did not include a company filing or statement confirming it.
Dealroom said AI agents such as Anthropic's Claude and OpenAI's Codex were increasing demand for tools that track their actions. It also said OpenAI's use of ClickHouse had grown over the past year as OpenAI moved parts of its business, including log management, away from Datadog, a point it attributed to a J.P. Morgan analyst note from May. Langfuse, an AI monitoring startup ClickHouse acquired earlier in 2026, pushed it further into observability. CEO Aaron Katz put gross margins at 50% to 70% and said, "If we wanted to be cash flow positive next year, we could be," while the company chose to invest in growth. Investors valued ClickHouse at $15 billion in January.

Why it matters
ARR above $350 million gives the $15 billion January valuation a reported revenue figure to be read against, though the figure rests on one unnamed source.
Growth was linked to AI agents and to OpenAI moving workloads such as log management from Datadog, so part of the demand cited comes from large AI users.
A gross margin of 50% to 70% per the CEO, against 79% at Datadog and 67% at Snowflake in the figures Dealroom cited, shows where the business sits among listed peers.
