KOL-style case note

This is the public 13F money map for D1 Capital Partners L.P..

Crossover manager linking public-market filings with private-market technology judgment. This page turns the latest public filing into a shareable research story: what the entity owns, which theme is driving the portfolio, and where to investigate next.

Who this is

Crossover manager linking public-market filings with private-market technology judgment. It belongs in a smart-money radar because its public 13F shows quarterly capital direction and theme preference.

Top holding

The latest filing's largest public position is CART, around 9.5% of the disclosed 13F portfolio. That is the first place to look for the current thesis.

Main theme

Mixed is the clearest public theme in the portfolio. The important question is whether that theme repeats across the top positions, not just whether one stock worked.

Portfolio shape

The latest public portfolio is about $10.7B, with 42 lines and roughly 49.8% in the top 10. Higher concentration means a few decisions can explain more of the proxy return.

Why track it

This is not a live trading signal. It is a quarterly capital map: start with the ranking, inspect the top holdings, then ask whether the manager has a repeatable framework.

How to read it

13F filings are delayed and incomplete. They do not show shorts, many derivatives, private positions, cash, or current trade timing. Use this page to generate research questions, not to replace diligence.

Smart Money VelocityVelocity score blends 13F value growth, concentration, theme purity, option exposure, and filing history. It is a prioritization score, not a return.

What is public, what is inferred

Public SEC data

13F reports disclose long reportable U.S. securities and long put/call options. They do not show cash, private stakes, shorts, written options, or current live holdings.

Inferred theme

Theme tags are deterministic product analysis from issuer, CUSIP, option type, and keyword rules. They are not SEC labels.
