Citigroup on June 11, 2026 launched Digital Depositary Receipts (DDRs), a tokenized instrument that converts private-company equity into blockchain-based securities tradeable alongside public stocks. The product, issued and custodied by Citi on infrastructure operated by Switzerland's SIX Digital Exchange, targets a late-stage pre-IPO market valued at approximately $75 billion. The inaugural transaction involved Citi Wealth clients acquiring tokenized stakes in Kaleido, a Citi Ventures-backed tokenization platform.
The launch comes as global secondary-market transaction volume for private company shares hit a record $226 billion in 2025 — up 41% year-over-year — while the IPO window remains largely shut for marquee technology firms. Citi says it is in discussions with "some of the world's largest private companies" to issue DDRs, though it has not named specific issuers. Distribution partners Sygnum Bank (Switzerland) and SBI Digital Markets (Singapore) will extend access to European and Asian institutional investors, with U.S. availability contingent on regulatory clearance.
Citi's DDR model adapts the depositary receipt structure — a decades-old instrument used for cross-border equity access (American Depositary Receipts being the most common) — to private-market shares. The mechanics:
The structure differs from synthetic exposure products. DDRs represent actual depositary receipt claims on underlying shares, not derivative contracts or price-tracking instruments. This distinction matters for both regulatory treatment and counterparty risk.
The pre-IPO secondary market has grown into a $67 billion addressable market in 2026, up from $58.2 billion in 2025, according to Intel Market Research. The market is projected to reach $210.5 billion by 2034, growing at 15.6% CAGR. Several structural forces drive this expansion:
Delayed IPOs. Companies including SpaceX (last valued at approximately $350 billion) and Anthropic remain private years beyond typical listing timelines. The median time to IPO for U.S. venture-backed companies has stretched beyond a decade. Employees, early investors, and institutions seeking exposure have limited options.
Secondary volume records. Global secondary transaction volume hit $226 billion in 2025, up 41% from 2024, according to JPMorgan data. GP-led secondary volume reached $47 billion in H1 2025 alone (up 68% year-over-year), while LP-led volume hit $56 billion (up 40%).
SPV friction. The dominant access vehicle for retail-adjacent investors — the special-purpose vehicle — carries opacity, illiquidity, and counterparty risk. SPVs bundle investor capital to purchase a single private-company position, but pricing is opaque, exit timing is uncertain, and fee structures average 1-2% management fees plus carried interest. The SEC has increased scrutiny of SPV-based tokenized share products following incidents like OpenAI publicly rejecting unauthorized tokenized exposure products in June 2025.
Citi's DDR model attempts to solve the friction problem by offering a regulated, custodied instrument with bank-grade settlement — removing the need for SPV intermediaries entirely.
SDX, the digital arm of Swiss exchange operator SIX Group, is the world's first fully regulated digital asset exchange and central securities depository (CSD) built on distributed ledger technology. Key facts:
For Citi, SDX provides critical regulatory cover. Operating on a FINMA-licensed DLT infrastructure means tokenized securities inherit the legal status of intermediated securities under Swiss law — the same classification as traditional book-entry shares. This is not a crypto exchange. It is a regulated financial market infrastructure that happens to use blockchain.
Citi has indicated plans to extend DDR issuance to additional blockchain networks. Whether that includes public chains like Ethereum remains unspecified.
Citi enters a private-market tokenization field with established participants on both the institutional and crypto-native sides:
Securitize commands the largest share of tokenized asset administration, with over $4.6 billion in tokenized AUM across partnerships with BlackRock, Apollo, Hamilton Lane, KKR, and VanEck. Securitize is going public via a reverse merger with a Cantor Fitzgerald-backed SPAC at a $1.25 billion pre-money valuation. Five of its administered tokens have individually exceeded $100 million in AUM. Securitize operates primarily as a platform and transfer agent — it does not custody assets or issue depositary receipts.
BlackRock's BUIDL, a tokenized U.S. Treasury money market fund administered by Securitize and launched in March 2024, has scaled past $2.5 billion in AUM. While BUIDL targets money-market exposure rather than private equity, it demonstrates institutional appetite for tokenized fund structures.
Apollo has launched tokenized fund products across six public blockchains, targeting broader distribution for its credit strategies.
NYSE and DTCC are developing parallel tokenization infrastructure projects, though these focus primarily on public-market instruments rather than private equity.
Citi's differentiator is structural. Unlike platform providers (Securitize) or fund tokenizers (BlackRock, Apollo), Citi combines issuance, custody, and distribution within a single $2.7 trillion balance-sheet institution. The DDR model eliminates the need for third-party custodians, transfer agents, or SPV managers — consolidating counterparty risk to a single regulated bank.
The risk of this consolidation: single-point-of-failure concentration. The benefit: reduced friction and fee layers.
The SEC's January 2026 guidance on tokenized securities established two categories with different regulatory treatment:
Issuer-sponsored tokenized securities: Represent actual equity ownership. Subject to standard securities registration and disclosure requirements. The SEC considers these functionally identical to traditional securities — "new plumbing, same rules."
Third-party synthetic products: Provide price exposure or custodial entitlements without direct share ownership. Subject to additional derivatives regulations and heightened scrutiny.
Citi's DDR structure positions itself in the first category. As a depositary receipt issuer with custody of underlying shares, DDRs represent direct claims on equity — not synthetic exposure. This matters because the SEC has signaled intent to curb synthetic equity products aimed at retail investors.
However, the product's initial limitation to non-U.S. investors suggests Citi is navigating a complex regulatory path for domestic distribution. The SEC has not issued specific guidance on tokenized depositary receipts for private-company shares, and the exemption frameworks (Regulation D, Regulation S) that govern private placements may require adaptation for a blockchain-settled instrument.
Citi's DDR launch lands one week after a broader bank tokenization announcement. On June 5, 2026, JPMorgan, Citi, Bank of America, Wells Fargo, and more than a dozen peers revealed plans for a shared tokenized deposit network through The Clearing House, targeting a first-half 2027 launch.
The network would convert traditional bank deposits into blockchain-based tokens enabling 24/7 settlement and programmable functionality — positioning regulated bank deposits as a direct competitor to stablecoins. The announcement explicitly frames the initiative as a defensive move: protecting the $17+ trillion U.S. commercial deposit base from stablecoin migration.
Two tokenization tracks are now running in parallel at Citi:
Together, they represent Citi's strategy to bring both the asset layer (equity) and the settlement layer (cash) onto blockchain rails. Whether these converge onto shared infrastructure — or remain siloed systems — will determine their long-term economic efficiency.
Issuer consent. Private companies must agree to DDR issuance. OpenAI's 2025 rejection of unauthorized tokenized exposure products demonstrates that company cooperation is not guaranteed. Citi's model requires issuer participation, which limits the product to willing companies.
Liquidity depth. A depositary receipt is only useful if secondary trading exists. SDX's current trading volumes for private shares are not publicly disclosed. Without sufficient market depth, DDRs risk becoming another illiquid private-market instrument — the same problem SPVs face.
U.S. access timeline. The product's initial restriction to non-U.S. investors excludes the world's largest pool of institutional capital. Citi has not provided a timeline for domestic availability. SEC clearance is the bottleneck.
Valuation methodology. Private-company shares lack continuous price discovery. How DDRs are priced — mark-to-market based on last funding round, independent appraisal, or secondary-market transactions — will affect investor confidence and regulatory treatment.
Competitive moat. The DDR structure can be replicated by any major custodian bank. JPMorgan, Goldman Sachs, and BNY Mellon all possess the custody, issuance, and wealth-management capabilities to launch similar products. First-mover advantage in institutional finance is typically measured in months, not years.
Citi's DDR launch is the first instance of a systemically important bank issuing tokenized private-company equity on regulated blockchain infrastructure. The product collapses the multi-intermediary chain of SPVs, transfer agents, and custodians into a single-issuer model — reducing friction but concentrating counterparty risk.
The economic logic is straightforward. The pre-IPO secondary market generated $226 billion in transaction volume in 2025 with settlement processes that remain largely manual, opaque, and slow. Tokenized depositary receipts on regulated DLT infrastructure can compress settlement from weeks to minutes while maintaining the custody and compliance standards institutional investors require.
Whether DDRs achieve meaningful scale depends on three variables: issuer willingness to participate, SEC clearance for U.S. distribution, and secondary-market liquidity on SDX. None of these are guaranteed. But with the tokenized RWA market at $32 billion and growing, the broader trajectory is clear: Wall Street is no longer experimenting with blockchain. It is building product on it.
