The London-based data intelligence company closed a $175 million Series F in March and is now weighing a public listing for the second half of 2026.
Quantexa, the British AI and data analytics company best known for helping banks catch fraud, is exploring an initial public offering that could value the firm north of $3 billion. The company is reportedly considering listings in both London and New York, with a potential timeline in the second half of 2026.
No final decisions have been made on timing or venue.
From Series F to IPO runway #
The IPO exploration comes just months after Quantexa closed a $175 million Series F funding round in March 2025. That round valued the company at $2.6 billion post-money, meaning the IPO target of exceeding $3 billion would represent a meaningful step up.
Since its founding in 2016, Quantexa has raised approximately $500 million to $545 million across multiple financing rounds. The company hit unicorn status in 2023, crossing the $1 billion valuation threshold, and has roughly doubled that figure in the two years since.
Quantexa employs between 800 and 891 people and serves clients in more than 70 countries. Its customer base skews toward heavily regulated industries, particularly banking and the public sector.
The company’s core product is its Decision Intelligence platform, which uses AI to analyze, link, and contextualize data across organizations. Banks use it to manage risk and compliance. Governments use it to detect tax fraud.
Why the venue question matters #
The choice between a London and New York listing carries real symbolic weight for the UK tech ecosystem. ARM Holdings, the UK’s most prominent chip designer, chose Nasdaq for its IPO in 2023. Flutter Entertainment moved its primary listing to New York. The UK government has actively tried to reform listing rules to make London more competitive.
US markets generally offer deeper liquidity, higher valuations for software companies, and a larger pool of tech-focused institutional investors. London offers proximity to the company’s headquarters and a regulatory environment the team already knows.
The AI enterprise gold rush #
Quantexa has secured agreements with HMRC, the UK’s tax authority, and formed a partnership with Zurich, the insurance giant.
The pre-IPO secondary market has already taken notice. Shares of Quantexa are available on platforms like EquityZen and Forge Global, where accredited investors can buy stakes in private companies before they go public.
Quantexa operates in a space that includes established players like Palantir, NICE Actimize, and SAS, as well as newer entrants riding the AI wave.
