Back in May, I wrote about Cache, the VC-backed startup that’s modernizing exchange funds, using portfolio assets to seed an Alpha Architect ETF, AAUS, in-kind.

Well… they’re about to do it again with a new Alpha Architect ETF, AAEQ.

Before jumping in, I’m grateful to Srikanth and Christopher from Cache for pulling out all the stops to answer my questions.

Here’s how this article flows:

  1. I’m going to do everyone a favor and keep the background reading brief. My previous article goes deep, so I would start there if you want the basics.

  2. Then, I’m going to address how everything has gone since the July 2025 in-kind seed. ETFs are transparent, and so is Cache, so this will be easy.

  3. I’ll address a reader question about how Cache enables liquidity for contributed shares before the seven-year disguised sale/anti-mixing bowl rules expire.

Curious investors should ping the managers right away:

  1. Nov 17-26 2025: Alpha Architect for details on directly contributing to AAEQ

  2. Dec 3: Cache for details on its next fund closing

To kick things off, here’s an artist’s interpretation of how the exchange-fund-to-ETF assets will flow.

Why would an exchange fund use portfolio assets to seed an ETF in-kind?
