Stated investment criteria
What One William Street Capital says it buys
Read from One William Street Capital’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.

A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. Nothing here is a commitment by One William Street Capital to consider any particular business, and nothing on this page is represented as being for sale.
SEC filings
What One William Street Capital has raised
From this firm's own Form D filings. A fund files one within fifteen days of its first sale, under penalty of perjury, which makes these the hardest numbers on the page.
| Vehicles filed | 3 |
| Total capital raised | $2.8bn |
| Largest single vehicle | $1.4bn |
| Filing history | 2014 |
| Smallest accepted commitment | $100k |
| Filed from | NEW YORK |
Form D covers US-domiciled vehicles raised from accredited investors. It will not capture a fund raised outside the United States, separately managed accounts, or capital deployed off balance sheet, so treat these as a floor rather than a total.
