About Us

The UK's leading marketplace for private company trading

JP Jenkins is the UK's leading marketplace for the trading of shares in private companies.

For over 30 years, we've helped growth-stage businesses, family-owned firms and venture-backed companies offer shareholders a fair, transparent way to buy and sell shares — all while remaining private.

Our FCA-regulated market is powered by our proprietary InfinitX technology, including an exchange-grade matching engine and connectivity to over 60 brokers, wealth managers and custodians.

How It Works

Investors place orders through their usual brokers. Trades execute on our regulated venue. Settlement flows through CREST. The result is a safe, orderly market for private-company trading.

Our Trading Models

Today, JP Jenkins offers two models of liquidity:

Private Market

Structured auction and intermittent trading events for companies with broader shareholder bases

Matched Bargain Facility (MBF)

Learn More

JP Jenkins sits at the heart of the UK's private-markets ecosystem, providing price discovery, transparency, and market structure for companies that aren't ready — or don't require — a public listing.
