Morningstar PitchBook US Modern Market 100

What it tracks

The Morningstar PitchBook US Modern Market 100 Index tracks 100 of the largest and most influential U.S.-domiciled companies—90 public and 10 private venture-backed. It uses a transparent, rules-based methodology, with companies weighted by market value. The index seamlessly integrates public and private markets to represent today’s expanding investment opportunity.

The only index here that is mostly public companies. It holds the largest US companies of both kinds in one basket, so it shows how much of a blended “public and private” product is actually the ordinary stock market.

Run by Morningstar Indexes, built with PitchBook. PrePost has no relationship with the provider and is not paid to list this index.

How the index is built

What is in it

Named constituents as of August 31, 2026.

Membership as the index provider published it on this date. PrePost shows which companies are in the index, not their weights. This index holds public companies as well as private ones. PrePost covers only the private ones.

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. Public means it has left the private market and can be bought through any broker.

The index provider lists this constituent only as “Figure”, with no identifier of any kind. PrePost has identified it as Figure AI on four grounds: the index selects the largest and most liquid unicorns; no separate Figure AI entry appears in any index we track; the other well-known company of that name, Figure Technologies, is an order of magnitude too small to qualify; and the two SEC-filing funds on this site that hold it, which must name portfolio companies precisely, both report it as “Figure AI, Inc.”. The provider has not confirmed this, and we have asked.

This company now trades on a public exchange. The index provider still lists it here, and its own indexes disagree about which side of the line it falls on. PrePost has taken it from SEC filings: funds on this site report it with a CUSIP, an ISIN and a quoted market price, none of which a private holding has.

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.
