Forge Accuidity Private Market Index

What this index holds, how it is built, and what its record does not cover. Forge Global, built with Accuidity.

What it tracks

Late-stage, venture-backed private companies in the United States, weighted by value rather than equally.

It publishes what each company is worth to the index as well as which companies are in it, and the answer is very concentrated: on the day this was read the largest single holding was just under 12% and the smallest was 0.13%. It also overlaps more with the companies PrePost already values than any other index here.

Run by Forge Global, built with Accuidity. PrePost has no relationship with the provider and is not paid to list this index.

Read this first

How it is built is not published

The provider publishes the holdings and their weights but not the rules that produce them: no inception date, no rebalance or reconstitution schedule, no stated weighting method, and no description of how the prices behind the weights are arrived at. Every one of those fields is empty on this page because the provider has not published it, not because PrePost did not look. PrePost has asked.

It is very concentrated

The weights published alongside the holdings ran from 0.13% to 11.98% on the day this was read. A small number of companies account for most of what this index does, which is worth knowing before reading a headline return from it.

The partner's website is no longer up

Accuidity, named in the index's own title, manages the strategy built to track it. On 2026-09-19 accuidity.com returned “Site no longer active” and redirected to Forge. PrePost records what it saw and draws no conclusion from it: a firm can change its website without anything else changing.

Private marks can be stale

Where a company's shares trade rarely, the last price can sit unchanged for months while the business underneath it moves. That is true of every index on this site.

Verified means a full PrePost profile with sourced figures. Listed means the company is named here because a benchmark we track names it; PrePost has published no figure for it and does not rank it.

Vehicles that track it

None that PrePost tracks. That does not mean none exists: a product can track an index without PrePost having verified it, and PrePost lists a vehicle only once it can source what the vehicle is and what it holds.
