LSE Pisces: Will the Private Securities Market Avoid the Fate of Goldman’s GSTrUE?

Marking its first year of operation, the London Stock Exchange’s private securities venue, Pisces platform, has hosted just four share auctions across three participating firms: Wayve, Moneybox, and Oxford Science Enterprises. Designed to provide liquidity for fast-growing companies without a full IPO, the venue has faced sluggish volumes amid wider market uncertainty.

The Balance Sheet of a Quiet Anniversary

The faint sound of a celebratory toast recently echoed through the Square Mile, noting twelve months since the London Stock Exchange secured a regulatory licence for Pisces. Here is the math: three registered private companies, four total transactions, and a market adoption rate that highlights corporate caution.

The Bottom Line

  • Low Velocity: Only three firms—AI developer Wayve, savings fintech Moneybox, and an ownership structure linked to Oxford Science Enterprises—have utilized the venue.
  • Structural Hesitation: Participants have leaned heavily into the “intermittent” nature of the platform, holding sparse auctions rather than maintaining continuous liquidity.

Parsing the Intermittent Liquidity Model

The “i” in Pisces stands for intermittent, granting member firms wide latitude on auction frequency. While Oxford Science Enterprises executes quarterly auctions, both Wayve and Moneybox treated their initial offerings as singular events. For buyers entering these private auctions, the exit strategy resembles a Hotel California dynamic: buying in is straightforward, but finding a secondary buyer proves difficult.

Macroeconomic headwinds have further dampened participation. Ongoing geopolitical friction, including uncertainty stemming from the Iran war, alongside a broader contraction in the traditional initial public offering pipeline, has kept private firms in a holding pattern.

Parallels to Goldman Sachs and the GSTrUE Precedent

Skepticism surrounding private trading venues is far from novel. Nearly two decades ago, Goldman Sachs launched GSTrUE—standing for Goldman Sachs Tradable Unregistered Equity platform—in early 2007. That initiative secured early commitments from prominent private equity giants Apollo and Oaktree, raising over $1bn in private equity capital.

However, the platform faltered when secondary market makers failed to materialize. As reported by The New York Times in 2012, trading on the exchange was described by one participating executive as happening strictly “by appointment.” Apollo transitioned to public markets in 2011, followed by Oaktree, effectively closing the chapter on the experiment.

Comparative Overview of Private Secondary Trading Venues
Platform Launch Year Initial Participants Outcome / Status After Year One
Goldman Sachs GSTrUE 2007 Apollo, Oaktree Severe liquidity shortage; both members eventually exited to public markets.

Revitalizing the Private Marketplace

Despite these early structural hurdles, institutional interest has not completely vanished. Reports indicate that major financial institutions, including JP Morgan, are evaluating potential roles within the Pisces ecosystem to help jumpstart secondary turnover.
