For founders building beside Robinhood: what it does in-house, where it picks partners and what stays open. Five businesses worth building, three design principles, four conditional paths for the chain and twelve indicators to check every quarter.

In one week of September 2026 the CLARITY Act stalled and the SEC issued a five-year innovation exemption for tokenized U.S. stocks. Robinhood's current Stock Tokens don't qualify. Four things it must do to enter: change the asset, build a venue, manage issuers and choose a ledger.

AMC asked Robinhood to stop its AMC Stock Token; Robinhood refused, then promised redemption and voting. Two weeks later the SEC's innovation exemption gave issuers written notice and 30 days to object. The spectrum of issuer rights, from no participation to issuer-sponsored.

Anthropic called transfers to SPVs void, and a pre-IPO token fell 45%. It still trades. Tokenization can get around exchanges, brokers and clearinghouses, but not a company's charter.

Robinhood Chain's revenue fell to under 0.4% of Robinhood's revenue by October. Measured by sequencer fees, it wasn't worth building. Read as the fourth barrier Robinhood is removing, it is a portfolio of options: tokenized U.S. equities, private-company tokenization, 24/7 settlement, AI agent accounts and low-cost international distribution.

On SpaceX's IPO day, Binance locked $557M in tokenized subscriptions and refunded all of it without delivering a single share. Tokenization wraps assets; it doesn't source them. When the underlying is scarce, that difference is everything.
