Synthetic Long and Short Private Indexes
Javier Avalos, co-founder and CEO of Caplight, on building synthetic derivatives of private stock
This points to private markets becoming tradable as a portfolio, not just one company stake at a time. Large LPs often own the same late stage companies through multiple managers, so a shock to names like Stripe or SpaceX can hit several sleeves of the same portfolio at once. A synthetic long or short basket would let them add or cut exposure quickly without selling fund interests or waiting months for company approved secondary transfers.

The practical problem is overlap. Endowments, pensions, and insurers can have VC funds, crossover funds, hedge funds, and direct positions all tied to the same private companies. Basket products turn that messy look through exposure into one hedgeable index trade.

This is different from a normal secondary sale. Selling private stock or an LP interest usually means brokers, approvals, documents, and settlement delays that can stretch for weeks or months. Caplight is aiming at an economic contract that settles faster, more like public market risk transfer than cap table surgery.

The closest analogue is what index futures and sector ETFs did for public markets. Once investors can hedge a whole basket instead of one name, more institutions can hold private exposure because they are no longer forced to be long only until an IPO, tender, or fund sale appears.
The next step is a split private market stack. Company approved tenders and stake transfers will keep handling actual ownership changes, while synthetic indexes handle fast portfolio level risk management. If that layer takes hold, private company exposure starts to look less like locked inventory and more like an asset class institutions can actively size up, hedge, and hold for longer.
