Exchange Funds: The “Rich Person’s ETF” for Tax-Free Diversification

By Team BMT Jan 29, 2026

💡 Executive Summary

  • Problem: You have $5M in a single stock (e.g., Apple) with a low cost basis. Selling it to buy a diversified index fund triggers a massive 23.8%+ tax bill.
  • Solution: Contribute your stock to an Exchange Fund. Other investors contribute their stocks (Google, MSFT, etc.).
  • Result: After a 7-year holding period, you can withdraw a diversified basket of stocks. The entire process is a tax-free contribution under IRC § 721.
⚠️ THE 7-YEAR LOCK-UP
To preserve the tax-free status, you generally cannot withdraw the diversified basket for 7 years. It is an illiquid strategy. If you need cash sooner, this is not for you (use SBLOC instead).

“Don’t put all your eggs in one basket” is good advice, but paying 30% of your eggs to the IRS just to move them to a new basket is bad advice. Exchange Funds allow Qualified Purchasers (Tier L2+) to swap their concentrated risk for a diversified portfolio without triggering a taxable sale.

🧐 Core Mechanic: The “Potluck” Party
Imagine a potluck where everyone brings one dish.
• You bring 100% Apple Pie (AAPL).
• Others bring Steak (TSLA), Salad (GOOG), and Wine (MSFT).
• At the end of the party (7 years later), you leave with a “Mix Plate” of everything. Because you never “sold” your pie, you pay no tax.
