Prof. Harold Tan's Portfolios on Autopilot: the AI Bottleneck Portfolio and Uncle Sam's Checkbook

I'm Chris, one of the co-founders of Autopilot. Two Portfolios, two very specific theses, both with unusually detailed descriptions of where the research comes from. That detail is the reason to read them.

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.

Who they are

Prof. Harold Tan publishes two Portfolios on Autopilot as an independent Pilot.

The Portfolios, and what each one says it does

The AI Bottleneck Portfolio is described around one idea: own the bottlenecks, not the applications. Rather than chasing large-cap chips, cloud platforms or whatever AI name is trending, it targets the scarce infrastructure layer that AI winners have to consume and few can replicate, selected for hard-to-replicate technology, capital-intensive supply chains and scarce inputs. The description says its sources are public company filings, earnings calls, investor presentations, industry research, semiconductor supply-chain analysis, energy and grid infrastructure data and Bitcoin network research, and that it is not generated by a black-box model or a short-term trading signal.

Uncle Sam's Checkbook is described as following federal spending into public companies, across national security priorities, semiconductor reshoring, AI infrastructure, grid modernization, nuclear power, defense technology, cyber, autonomy and space. Its stated sources are federal spending and contract award databases, public program announcements, official agency releases, company annual and quarterly filings for federal revenue exposure, and earnings calls for backlog and guidance. The description is explicit that it follows public spending signals rather than any individual's trades.

What to check before you follow

Both are concentrated theses about how a specific part of the economy will develop. A thesis can be right about the direction and wrong about the timing, for longer than you expect to wait.

A government-spending Portfolio is exposed to policy and budget changes, which are not predictable from filings.

Read the Portfolio's own description in the app, because that's the Pilot's statement of method. Look at the worst decline rather than the return, because that's the number that decides whether you hold on. Check how often it changes, since turnover costs money and creates taxable events in a taxable account. And check the fee at your balance, which is arithmetic in What Autopilot's fee actually means at your balance.

How following works

You pick the Portfolio, connect the brokerage you already use, and allocate money. You give Autopilot Advisers limited authority to send orders to the account you already have. When the Portfolio changes, we send them and your broker fills them. The money stays put.

What it costs

A flat cash subscription, not a percentage of your balance. Per our Form CRS dated February 2026, Basic Tier has no Base Advisory and Licensing Fee, and Premium Tier is $29.99 to $199.99 a quarter or $99.99 to $699.99 a year. Pilot subscriptions are separate and add on if you follow more than one Portfolio. Because it's a flat dollar amount, it's a bigger share of a small account than a big one, so do the math at your balance.
