The Leopold Aschenbrenner Tracker: what it follows from Situational Awareness LP's filings, what a 13F can't tell you about an AI fund, and how following works

I'm Chris, co-founder of Autopilot. Most of the hedge fund trackers we publish follow people who have been famous for decades. This one follows someone who was an AI researcher two years before he ran a fund. Leopold Aschenbrenner's Situational Awareness LP files a 13F like any other manager over the threshold, and the Leopold Aschenbrenner Tracker follows those filings. Here's who he is, what the fund is, what the filing shows and leaves out, and how following works.

One thing first, because we're an SEC-registered investment adviser and I have to say it. Autopilot is the app. The actual investment advice comes from Autopilot Advisers, LLC. If you want the full legal version of anything in here, it's on our disclaimer page.

1) Who he is

Leopold Aschenbrenner graduated from Columbia University as valedictorian in 2021, at nineteen. He joined OpenAI in 2023 on its Superalignment team and left in 2024. That year he published "Situational Awareness," a long essay series arguing that artificial general intelligence is closer than most people think and that the economic consequences will be enormous. The essay got wide attention, and it became the name of his hedge fund, Situational Awareness LP, which invests in companies involved in AI, private and public. He has no relationship with Autopilot, doesn't run this Portfolio, and hasn't endorsed it.

2) The fund, on the public record

Situational Awareness LP is an SEC filer, CIK 2045724, based in San Francisco, and it files Form 13F-HR every quarter, which means it manages more than the reporting threshold in US-listed securities. Its first 13F on EDGAR was filed February 12, 2025, for the quarter that ended December 31, 2024, and it has filed each quarter since; as of this writing, its newest filing was made on August 14, 2026 for the quarter ended June 30, 2026. That's the whole public record of what the fund holds: one snapshot per quarter, filed up to 45 days after the quarter ends, listing US-listed long positions and certain options, and nothing about the private investments the fund also makes. How to read one of those filings line by line is in How to read a 13F filing, line by line: what's in it, what's missing, and how it differs from 13D and 13G.

3) What the Tracker is

The Leopold Aschenbrenner Tracker launched on Autopilot on March 5, 2026. Autopilot is the Published Pilot and Autopilot Advisers, LLC is the manager, and it's included in the Premium Tier bundle of Autopilot-run Portfolios. Its published description says it "is inspired and tracks positions from Situational Awareness LP." The Leopold Aschenbrenner Tracker fact sheet shows its largest positions by weight with a timestamp, lists the rebalance cadence as not disclosed, and publishes the live record of follower accounts since launch, gross and modeled net, with drawdown and a date on every figure. I don't put holdings or returns in articles, because both change and this page doesn't; read the sheet.

4) What a 13F can't tell you about an AI fund

Three gaps matter more for this fund than for most. First, the private side: a fund that invests in private AI companies has a whole book the 13F never shows, so the Tracker follows only the public slice. Second, the lag: 45 days after quarter end is a long time in a sector that moves this fast, and the fund can be somewhere else entirely by the time the filing appears. Third, size and turnover: a young fund's filings can change a lot from quarter to quarter, which means larger rebalances in your account than a Buffett-style tracker would produce. None of those are criticisms of the fund; they're properties of the document. I wrote up what the lag does to a follower in How to see what Berkshire bought: reading the 13F, the amendments, and the 45-day gap, and it applies here with more force.

5) How following works

You connect the brokerage you already have, pick the Portfolio, and set how much of the account follows it. Then you give Autopilot Advisers limited authority to send orders to that account. When the Portfolio changes, we send them and your broker fills them. The money stays put. You're never trading at the same time as the fund; you're following a filing that came out weeks after the fund traded, and your holdings won't match the Portfolio exactly because account size, brokerage support for fractional shares, and trade timing all change what lands in your account.

6) Who this is for

Someone who read the essay, believes the thesis, and wants the public-market expression of it that the fund's own filings reveal, with the record started on March 5, 2026 and not a day earlier. Read the drawdown on the sheet before the return, and judge the Portfolio by its own record rather than by the fund's reputation, which the record doesn't include. The other trackers we publish, and how each one works, are in Every hedge fund and Wall Street Portfolio you can follow on Autopilot, and how each one works, and how to weigh any of them is in How to choose which investor to follow: attribution, survivorship, concentration, and when to stop.

Who is Leopold Aschenbrenner?

A former OpenAI researcher turned investor. He graduated from Columbia as valedictorian in 2021, joined OpenAI's Superalignment team in 2023, left in 2024, and that year published "Situational Awareness," an essay series arguing that artificial general intelligence is near and economically enormous. The essay became the name of his hedge fund, Situational Awareness LP, whose 13F filings Autopilot's tracker follows. He is not affiliated with Autopilot.

TLDR

A researcher's thesis became a fund, the fund files a 13F, and the Tracker follows the filings: the public slice, on a 45-day lag, with a record that starts March 5, 2026. Read the fact sheet's drawdown before the return, remember the private book you can't see. If one fits, choose a Portfolio and connect your brokerage. Then give Autopilot Advisers limited authority to send orders to that account. When the Portfolio changes, we send them and your broker fills them. Depending on your plan and brokerage, you may need to confirm first. The money stays put.
