Relativity Files Confidentially for US IPO

Relativity, a Chicago-based legal data company, confidentially filed for a US IPO on March 19, 2026.

The filing marks a significant moment for the legal technology sector, which has seen very few public listings and mixed results from those that have attempted it. Relativity's move tests whether public markets are ready to absorb a platform-scale legal tech company, and its outcome may shape the strategic decisions of other high-value private players in the space.

The Filing

Relativity submitted a draft registration statement to the US Securities and Exchange Commission (SEC) on March 19, 2026. A confidential filing allows companies to prepare for an IPO without immediate public scrutiny of their financial details.

The company has not yet set a share count or price range for the proposed listing. The IPO remains subject to the completion of the SEC review process and prevailing market conditions.

Relativity is backed by private equity firm Silver Lake and was valued at approximately $3.6 billion in March 2021, according to PitchBook data. The company has raised roughly $2.35 billion to date and completed a $920 million debt refinancing in January 2026.

Company Background

Relativity was founded in 2001 by Andrew Sieja. It initially built tools to manage digital evidence for litigation before expanding into broader legal data analytics.

Its flagship cloud product, RelativityOne, uses machine learning to prioritize relevant documents in large document reviews. This reduces the time and costs involved in complex legal processes such as investigations and disputes.

The company's scale, profitability trajectory, and position as core infrastructure for large-scale legal matters had made its IPO widely anticipated within the industry.

Market Conditions

The filing comes at a difficult moment for US public markets. IPO activity is already under pressure from a software sector selloff, and broader markets face additional strain from Middle East tensions.

Investor caution around new listings is high. The legal technology sector, in particular, has historically faced skepticism from public market investors due to the slow sales cycle of law firms, which have been slow to adopt new technology.

Legal Tech IPO Track Record

The legal tech sector has produced very few public listings. The last cluster came in 2021, when Disco, Intapp, and LegalZoom all listed on US exchanges.

Disco, a Relativity competitor in the eDiscovery space, went through a difficult period that included significant layoffs and the departure of its founder, Kiwi Camara. Intapp's stock price has remained volatile since its listing. LegalZoom performed strongly for a period but has since faced pressure from competition and AI-related disruption to its core business model.

Other high-value private legal tech companies are watching Relativity's filing closely. Clio, which raised a $500 million Series G funding round in 2025, carries a valuation of $5 billion. Other privately held companies in the sector that have received significant investment and are considered potential IPO candidates include Harvey, Ironclad, Filevine, EvenUp, Legora, and Everlaw.

What Comes Next

Relativity's listing could establish valuation benchmarks for the next generation of legal technology companies seeking public market exits. It may also influence how investors assess platform-scale legal tech providers more broadly.

Whether the listing triggers further IPO activity in the sector remains to be seen. The outcome will likely influence strategic planning at the upper tier of privately held legal technology companies.
