• Databricks is in the middle of a mega funding round, several people familiar with the matter told CNBC. 
• The data analytics and AI company is raising at least $5 billion in cash, pegging its new valuation at $55 billion, according to the sources.
• The software company is already one of Silicon Valley's most valuable private startups and has been viewed as a potential IPO candidate.
• But this funding round pushes its public debut prospects further down the road, one source told CNBC. 

One of the world's most valuable private tech companies is raising billions more in cash and is in no rush to go public, sources told CNBC. 

San Francisco-based Databricks is raising at least another $5 billion in its latest funding round, though it could raise up to $8 billion given the round is ongoing, according to several people familiar with the matter, who asked not to be named because the discussions were private. The latest raise would value the company at $55 billion and could top the largest round of the year, by OpenAI.

The latest funding is designed to help Databricks employees sell shares, one of the people said. Reducing pressure from employees to cash out also reduces the need for a liquidity event such as an IPO. One source said the funding round makes Databricks' highly anticipated public debut less urgent. But it could still happen in the back half of next year.

Databricks was founded in 2013 and sells software that helps enterprises organize data and build their own generative AI products. It uses machine learning to help clients from AT&T to Walgreens parse and make sense of massive troves of data. 

This equity round could be the largest in a banner year for artificial intelligence funding, when 1 in 3 venture dollars has gone to an AI startup, according to CB Insights. OpenAI holds the record in 2024, raising $6.6 billion in October at a $157 billion valuation.

Databricks last raised $500 million at a $43 billion valuation. It's backed by Nvidia, Capital One, Andreessen Horowitz, Baillie Gifford, Fidelity, Insight Partners, Tiger Global and others. 

The Information first reported that Databricks was raising money.

The firm has capitalized on the momentum in artificial intelligence. This summer, it acquired MosaicML, a $1.3 billion software startup that focuses on large language models that can churn out natural-sounding text. Databricks told investors earlier this year that annualized revenue would hit $2.4 billion by the midpoint of 2024.

Its decision to stay private comes as software stocks have struggled to get out of a rut brought on by higher interest rates. Shares of rival Snowflake are down 13% this year. While its fellow software IPO candidates such as Stripe have taken significant haircuts on valuations, Databricks has grown its value while expanding its employee base. 

CEO Ali Ghodsi said at a conference Nov. 20 that he's optimizing for the success of Databricks over the next decade or two, not optimizing for an IPO.

"If we were going to go, the earliest would be, let's say, mid-next year, or something like that," Ghodsi said at Newcomer's Cerebral Valley AI Conference. "So, you know, could happen next year."

A Databricks spokesperson declined to comment.
