Citi launches blockchain marketplace for private-company shares

Citigroup is launching a blockchain-driven marketplace for private company shares, aiming to give wealthy and institutional investors a new route to pre-IPO exposure through tokenized instruments.

According to The Wall Street Journal, the platform will issue tokenized depositary receipts that represent ownership interests in private firms. The rollout will start with foreign investors, with a U.S. access plan to follow. Citi executives described the approach as enabling investors to hold private-company shares “right next to” their Apple stock within a familiar brokerage framework.

The project hinges on tokenization to modernize private markets. Citi argues that structuring private investments through tokenized depositary receipts can offer greater transparency than traditional private structures such as special-purpose vehicles, which have grown pervasive but exposed to opaque governance and limited visibility for investors.

The infrastructure behind the venture will be provided by SIX Digital Exchange, a subsidiary of SIX Group, the operator of Switzerland’s stock market. Citi said it is already in discussions with several large private companies about listing their shares on the platform, signaling a potential early slate of listings once the platform launches.

Key takeaways

• Platform mechanics on a familiar rails: Citi will issue tokenized depositary receipts backed by private-company ownership; foreign-investor access is planned first, with a U.S. rollout later; SIX Digital Exchange will power the blockchain layer.
• Transparency over opacity: Citi positions tokenized receipts as a more transparent alternative to SPV-based access to private equity and late-stage private stakes.
• Private markets’ long-run outperformance: PitchBook data summarized by the American Investment Council indicate private equity has outperformed the S&P 500 across 5-, 10-, 15-, and 20-year horizons, underscoring why market participants want broader access to pre-IPO exposure.
• Rising demand tempered by caution: Demand for tokenized pre-IPO exposure is rising—exemplified by high-profile IPO fervor—but investors should heed warnings about tokenized stock structures not representing equity, as OpenAI has cautioned.

Platform mechanics and governance

The reported plan frames Citi’s new marketplace as a direct on-ramp to private ownership through blockchain-enabled receipts. Tokenized depositary receipts will represent genuine ownership interests in private companies, with SIX Digital Exchange providing the underlying ledger and settlement infrastructure. Citi indicates it has engaged with several large private firms about listing their shares on the platform, signaling that the first wave of offerings could include substantial pre-IPO stakes.

While tokenization promises streamlined ownership records and potentially clearer governance, advocates acknowledge that valuation and liquidity dynamics for private shares remain complex. The platform’s success will hinge on how readily investors can buy, sell, and reconcile these receipts in real time, how dividends or distributions (if any) are handled, and how regulators oversee tokenized private equity transactions as they intersect with traditional markets.

Private markets in the spotlight

The broader appeal of pre-IPO investing has intensified as fintechs and traditional financial players explore tokenized access to private assets. Long-run performance trends in private markets have reinforced the appeal: data cited by the American Investment Council, drawing on PitchBook, show private equity delivering stronger returns than the S&P 500 across five-, ten-, fifteen-, and twenty-year horizons. Will Dunham, president and CEO of the council, has argued that this long-run outperformance strengthens the case for expanding retail access to private markets through regulated investment vehicles, including those tied to retirement portfolios.

Beyond Citi’s venture, the ecosystem is already experimenting with tokenized exposure to private companies. Some platforms offer tokenized representations that provide economic exposure, rather than direct equity ownership. OpenAI’s tokenized-stock warnings—issued last year—underscore a critical caveat: tokenized securities may not confer actual equity rights in the underlying company, a nuance that has important implications for investors seeking true ownership or voting rights.

Market signals and the road ahead

The appetite for tokenized and private-market access is underscored by high-profile IPO dynamics. Bloomberg has reported that SpaceX’s upcoming public listing has drawn substantial retail interest, with reported orders exceeding $70 billion ahead of the offering. This level of activity highlights a broader shift in how investors approach large-valuation, high-profile listings, and it echoes the growing willingness of retail and institutional buyers to participate in tokenized or blended private-to-public journeys.

At the same time, the ecosystem remains nuanced. Platforms like Kraken’s xStocks have seen significant on-chain activity as part of the push toward tokenized equities, illustrating how retail participants are experimenting with tokenized exposure to private and public offerings. Yet the landscape is not without risk: OpenAI’s caution about tokenized stocks remains a salient reminder that tokenized formats can diverge from direct equity rights, potentially affecting valuation, voting, and rights to dividends.

As Citi advances toward a potential rollout, observers will watch regulatory clarity, liquidity dynamics, and valuation standards to determine whether tokenized private-share platforms can scale into durable capital-formation channels or whether they remain a niche instrument tied to select institutions.

Watch for regulatory updates and liquidity progress in the coming months, as markets weigh whether tokenized private shares can meaningfully broaden access to private markets while preserving investor protections and price discovery. The outcome could shape how banks and fintechs collaborate to reframe private equity access for a broader audience.
