Forge Vertical Integration and ATS Moat

Forge is hard to dislodge because it turned a messy, broker driven niche into an integrated market stack. In private secondaries, the real bottleneck is not just finding buyers and sellers, it is verifying ownership, handling transfer restrictions, settling trades, safeguarding assets, and producing pricing data that institutions trust. Forge built across those layers, then added ATS status and custody, which means a newcomer has to rebuild workflow, compliance, and liquidity all at once.

• Private secondaries are operationally ugly. Deals can take weeks or months to close because shares need issuer approvals, transfer review, and ledger updates. That is why data, execution, and settlement belong together. A platform that already controls more of that flow can close faster and produce cleaner market signals.

• Forge has long aimed at larger institutions, with higher minimum trade sizes, an institutional desk, and later a broader bundle of marketplace, custody, and data tools. That matters because institutional buyers care less about a pretty front end and more about whether a $5M block can actually clear, settle, and be held compliantly.

• The closest rivals each own only part of the stack. Nasdaq Private Market is strongest in issuer run tenders. Carta's edge came from the cap table system of record. EquityZen is strongest at packaging smaller investor demand. PreStocks abstracts the plumbing with SPVs and tokens, but still sits outside issuer approval, ATS rails, and traditional custody infrastructure.

The market is moving toward a few deeper platforms that combine software, regulated market access, and post trade infrastructure. That favors incumbents like Forge, while newer entrants will keep winning in narrow wedges such as tokenization, issuer workflows, or retail access until they either add regulated infrastructure or plug into someone who already has it.
