Wayve Files an $85m Employee Share Sale on London's PISCES, the First Big Test of Britain's Private Market

For years the frustration voiced by British founders and the people who build alongside them has been the same. You can grow a company worth billions in London and still find that nobody who helped create that value can realise any of it, short of selling to an overseas buyer or waiting out an IPO that keeps slipping over the horizon.

On 1 July however, one of the country's most valuable private companies decided to test a different route, and in doing so handed the UK's new private market its first real proof of concept.

Wayve, the London based autonomous driving company, has filed to run an 85 million dollar (63 million pound) employee share sale on the London Stock Exchange's Private Intermittent Securities and Capital Exchange System, known as PISCES. The transaction values the business at 8.6 billion dollars and is the first high profile use of the platform by a major UK technology firm. A closed auction is scheduled for 8 July, at which employees will be able to sell part of their vested equity to approved investors.

Crucially, this is a liquidity event, not a fundraising. Wayve is not issuing new shares or raising fresh capital. Staff are selling existing shares they already own, and the company is using the auction to let them crystallise some of the value of their holdings without waiting for a listing. Chief executive Alex Kendall described the deal as a way to retain and reward the best talent in the industry, and noted it was the second time the company had done this.

The sale follows Wayve's 1.2 billion dollar Series D in February, which set the same 8.6 billion dollar valuation, and a further 60 million dollars from AMD, Arm and Qualcomm. Its backers include Microsoft, Nvidia and Uber, and its workforce has roughly doubled to around 1,200 over the past year.

Why this matters to founders

PISCES was built to fill the awkward gap between venture funding and a public listing. It gives founders, employees and early investors a regulated way to sell shares in a private company during set trading windows, without forcing that company to float before it is ready. As an aside, Monzo was in a comparable position but solved it differently: its 2024 employee secondary let current staff sell up to 40% of their equity to existing backers like GIC and StepStone, yet former employees were excluded and had to petition the board - a reminder that a company-arranged secondary reaches whoever it chooses, while everyone else is left making private deals. Retail of course, had no viable options.

For a founder, that changes the calculus of how you hold a team together through the long years between a big raise and any eventual exit. Share options only motivate people if there is some realistic prospect of turning them into money. When companies stay private for a decade or more, as the best AI companies increasingly do, that prospect can feel abstract. A working secondary market makes it concrete.

It also speaks to a quieter structural argument the UK has been making about where its best companies end up. Wayve is exactly the kind of business ministers hoped would use the platform, a British champion with a multibillion dollar valuation, blue chip backers and no immediate plan to list.

LSEG chief executive Dame Julia Hoggett said the auction showed the growing momentum behind the market and how it could help companies deliver liquidity for employees while supporting the next stage of growth. Independent voices were more measured. Dan Coatsworth of AJ Bell called it a test of investor demand for autonomous driving and of whether the platform is fit for purpose, while PitchBook's Navina Rajan noted that secondary share sales are fast becoming a core feature of the late stage venture market rather than an exception.

The founder access point sits underneath all of this. The debate PISCES belongs to is not about opening private companies to retail investors. It is about whether the people who take the earliest risk, founders, staff and early backers, can reach willing qualified buyers without surrendering control. An IPO or a trade sale hands power to new owners, a board and a set of terms.

A secondary window lets a company reward its team and refresh its share register while staying independent. That is a meaningfully different bargain, and it is the one the UK is now trying to make routine.

The part that is still being built

The timing carries a sting for sellers. Until 30th June, trading on PISCES cost nothing in transaction fees. From 1 July the first real price applied, with the seller paying one per cent and the buyer exempt. Wayve's auction is therefore not only a test of demand for autonomous driving, but the first sizeable trade to run under the platform's actual economics.

There is a longer arc here worth naming. PISCES provides the trading venue. It does not by itself modernise the plumbing underneath, where share registers, cap tables and settlement still rely on manual reconciliation with Companies House. This is where tokenisation enters the picture, not as hype but as the logical next layer.

A tokenised share register, with the legal holding sitting in a compliant nominee or custody structure and Companies House remaining the source of truth, could make intermittent windows cheaper to run, easier to settle and potentially more frequent. Paired with a venue like PISCES, tokenised equity is the mechanism most likely to turn today's occasional set piece auction into something closer to organic, incremental liquidity for private companies.

That future is not here yet, and the open questions are real. How a tokenised ledger reconciles with Companies House in practice, what custody structures satisfy both the FCA and HMRC, and how tax reliefs travel with a tokenised share all remain to be settled. But the direction is clear enough. Wayve has shown that the appetite for private liquidity in Britain is real and sizeable. The infrastructure now has to prove it can serve that appetite at a cost and a cadence that founders and their teams can actually use.

Key Takeaways

• Wayve has filed an 85 million dollar employee share sale on the London Stock Exchange's PISCES platform, valuing the company at 8.6 billion dollars, with a closed auction set for 8 July.

• It is the first high profile use of PISCES by a major UK technology firm and a live test of whether Britain's private market reforms can provide liquidity without pushing companies towards a US IPO.

• The deal is an employee liquidity event, letting staff sell vested shares to approved investors, not a capital raise.

• For founders, a working secondary market makes equity a credible retention tool and offers a route to reward teams while staying private and independent.

• The next frontier is the settlement layer, where tokenised equity could make these windows cheaper and more frequent, though reconciliation with Companies House and custody rules remain open questions.
