Alto to buy Forge Trust from Schwab, combining over $20 billion in retirement assets

Alto has agreed to buy Forge Trust from Schwab, an acquisition the Nashville self-directed IRA custodian and broker-dealer says would place more than $20 billion in retirement assets under custody and administration on a single platform built for investing in private companies and funds. The agreement covers Forge Trust Co. and its parent, Forge Services Inc., both part of Forge Global, the private-shares marketplace Schwab acquired earlier this year. Completion still requires approval from the South Dakota Division of Banking, and Alto says the combined business would then hold more than 60,000 self-directed IRA accounts with private-market assets.

A self-directed IRA gets the same tax treatment as a standard individual retirement account. What changes is the custodian's latitude, which runs past publicly traded stocks, bonds and funds to private equity, venture capital, real estate and private credit. That range is the selling point and the exposure at once. In a 2023 investor alert issued jointly with NASAA and FINRA, the Securities and Exchange Commission cautioned self-directed IRA owners weighing alternative assets such as real estate, precious metals, crypto and private placements that the risks can include a lack of information and liquidity, and the risk of fraud.

The administrative cost of each private position lands on the custodian, and according to Alto that burden is why brokerages have generally avoided self-directed IRAs. Treat the claim as the deal's premise and the logic turns straightforward: what has held the category back is operational rather than a shortage of willing clients, and the asset worth buying is a set of accounts already equipped to hold what a conventional custodian will not. Forge Trust has been operating for more than 40 years, which makes its clients veterans of the arrangement rather than recruits to it.

Scale is the other half of the case, and Alto's own numbers frame it. In an August announcement, the company said it was custodian for roughly $2 billion held by more than 32,000 self-directed IRA investors as of June 30. Its Tuesday statement did not say how much of the combined total comes from Forge Trust, though the midyear disclosure suggests the acquisition target makes up the lion's share. The arithmetic points the same way: a $2 billion base cannot account for most of a book described as exceeding $20 billion.

Retirement custody is not the only thing being combined. Alto says the merged company would carry more than three million accounts in its custody-as-a-service operation, the unit that lets other firms plug Alto's custody and compliance tools into their own platforms. That is a different business from holding illiquid assets and answering for them, since the first is infrastructure sold to other firms and the second is administration the custodian answers for directly, and three million accounts is enough to make the custody-as-a-service arm, rather than either retirement book, the bulk of the platform's account count.

Read that way, the contest is less about which funds reach which platform than about who administers the position once it is bought. A self-directed IRA custodian handles every capital call, valuation and distribution a private holding generates, the recurring work Alto points to when it says brokerages have stayed out. An advisor who has carried a private fund inside a client's retirement account knows the shape of that work, because it is servicing rather than judgment, and it does not scale by adding another planner. An established trust book hands that work to the buyer along with the accounts.

If the binding constraint on retirement money reaching private markets is operational, then the competition worth watching runs through the custodian rather than the fund shelf. The self-directed IRA is the structure that allows a private holding to sit inside a retirement account at all, and the custodian is the firm obliged to absorb the paperwork when it does. Four decades in the trust business also spans more than one full private-market cycle, which is a different kind of evidence for the demand case than a book assembled in the last few years.

Schwab's reasoning is the question the announcement does not answer. Forge Global joined Schwab earlier this year, and the report gives no explanation for why the trust business is moving on now. It also gives no purchase price for the transaction, which leaves the size of Alto's step-up measurable in accounts and assets rather than in what it paid for them.

Approval from the South Dakota Division of Banking is the gate, and no timetable for that review appears in the announcement. Until it clears, the two books stay separate, and the only figure Alto has attached to the combination is the one at the top: more than $20 billion in retirement assets under custody and administration, with more than 60,000 private-market accounts riding on a state regulator's signature.
