InfinitX

InfinitX is a financial markets infrastructure company focused on transforming how private markets operate. It owns and develops the core technology and regulatory framework behind JP Jenkins, the largest regulated private market in the UK, enabling companies to access liquidity using public market infrastructure.

InfinitX is built on a clear thesis: private markets have outgrown their infrastructure. While public markets benefit from standardised trading, transparent price discovery, and efficient settlement, private markets remain fragmented, illiquid, and opaque. This creates challenges for companies, investors, and employees seeking liquidity or reliable valuations. InfinitX addresses this by bringing the structure and discipline of public markets into the private environment.

Through JP Jenkins, InfinitX operates a regulated venue where securities in private companies can be traded via a network of FCA-authorised intermediaries. Transactions settle through CREST on a T+2 basis, delivering institutional-grade infrastructure, governance, and trust. The platform supports both matched bargain trading and structured liquidity events under the UK’s PISCES framework, allowing companies to control how and when liquidity is provided.

InfinitX has played an active role in shaping this regulatory evolution, working closely with HM Treasury and the FCA on PISCES. This positions the business at the forefront of a new category: regulated private market trading.

The model is designed to scale internationally. InfinitX intends to replicate its UK approach in markets such as Australia and North America, creating globally connected private markets that enable capital to flow more efficiently across borders.

Ultimately, InfinitX is not just building a platform — it is building core financial market infrastructure for private companies, supporting liquidity, price discovery, and long-term economic growth.

InfinitX formally began in 2021 with a clear ambition: to build the technology capable of bringing public market infrastructure into private markets. In the early stages, the focus was on developing a scalable, regulated-ready platform that could support trading, settlement, and connectivity in a way that mirrored public markets.

In 2023, we took a significant step by acquiring JP Jenkins. This provided a route to market — not just to deploy our technology, but to operate within a regulated environment and prove the model in practice. Rather than building in isolation, we embedded our technology into a live venue, refining it alongside real companies, brokers, and investors.

Since the acquisition, JP Jenkins has evolved into the largest regulated private market in the UK, operating under FCA authorisation and at the forefront of the UK’s PISCES framework. We have worked closely with regulators and policymakers, contributing to this new market structure and demonstrating its viability through live transactions.

We have built the core components of a modern private market — including broker connectivity, structured trading models, and settlement through CREST — while establishing strong relationships across the ecosystem.
Today, InfinitX operates with teams in London and Glasgow, combining market expertise with technology development to scale the business. What began as a concept has become a functioning, regulated market infrastructure — with a clear path to international expansion.

Crucially, our impact is now being felt. By unlocking liquidity in private companies, we are helping to free up locked capital and drive reinvestment into new opportunities, creating a flywheel of economic activity that supports the next generation of growth businesses.
