Mubadala Capital and KAIO Tokenize $75M Private Markets Fund on Solana, Base, and Sui as Coinbase Takes Stake

KAIO and Mubadala Capital went live on July 23 with the tokenized version of Mubadala's Alternative Solutions Fund, named MCAS-TA, drawing approximately $75 million in on-chain commitments at launch across three networks: Coinbase cbBTC$63,888.38-1.2%'s Base, Solana, and Sui.

The offering marks the first time Abu Dhabi's sovereign wealth management arm has moved a live alternatives product to blockchain infrastructure. Mubadala Capital manages and advises more than $430 billion in assets for institutional clients across private equity, credit, venture capital, and co-investment, operating as an alternatives platform within Mubadala Investment Company, one of the world's largest sovereign wealth funds.

Why Private Market Tokenization Is Harder Than Treasury Bills

Most tokenized funds to date have targeted liquid assets: Treasury bills, money market funds, and investment-grade bonds. Those instruments generate early wins because they trade in standardized blocks with continuous price discovery and established settlement rails.

Private markets are structurally different. Alternative investments (private credit, private equity, co-investment funds) are illiquid by design, carrying lock-up periods, irregular distributions, and subscription processes that have historically required legal counsel, high minimum commitments, and direct relationships with fund managers. Moving them on-chain doesn't simply digitize paperwork; it enables faster settlement, creates pathways for secondary market liquidity, and can extend qualified-investor access to fund strategies that were previously gatekept by geography and size.

Max Franzetti, Head of Mubadala Capital Solutions, described the rationale: "This strategy was built on differentiated access — to deal flow, to co-investment, to a global network that most investors cannot reach."

Access to MCAS-TA is restricted to qualified institutional and accredited investors, keeping the offering inside established regulatory guardrails while moving the underlying mechanics on-chain.

KAIO: Abu Dhabi's Compliance-Embedded Tokenization Infrastructure

KAIO is an Abu Dhabi Global Market (ADGM)-registered tokenization platform that embeds regulatory compliance from Abu Dhabi, the Cayman Islands, and Singapore into its fund distribution infrastructure. The firm, formerly known as Libre and co-founded with involvement from Nomura's Laser Digital, builds infrastructure that allows institutional asset managers to issue, redeem, and transfer tokenized fund shares across multiple chains and jurisdictions.

Before the Mubadala partnership, KAIO had tokenized strategies from BlackRock, Brevan Howard, Hamilton Lane, and Laser Digital, accumulating roughly $144 million in on-chain assets. In April 2026, Tether led an $8 million strategic funding round for KAIO, its largest single raise, bringing its total capital to $19 million and specifically targeting expansion of USDT liquidity into regulated investment products.

The three-chain deployment of MCAS-TA reflects deliberate infrastructure strategy. Solana was selected for throughput and settlement speed. Base provides regulatory compliance tooling and integrates with Coinbase's institutional custody infrastructure, while Sui handles the complex financial instrument logic required for an evergreen private markets structure.

Coinbase in Two Roles: Builder and Balance-Sheet Investor

Coinbase holds an unusual position in this launch. As the operator of Base, it provided core network infrastructure. But Coinbase also moved a position in MCAS-TA onto its own corporate balance sheet, investing directly in the fund rather than merely servicing it as a vendor.

Brett Tejpaul, Head of Coinbase Institutional, articulated the broader thesis: "As regulated assets become programmable, they can become part of a broader onchain economy that is more transparent."

The combination of infrastructure co-builder and direct balance-sheet investor is uncommon among large public companies in the tokenized asset space. For Coinbase, holding a regulated tokenized private fund as a treasury asset signals that the category is mature enough for corporate capital allocation, not just product development. That signal matters independently of the fund's size.

Solana's Growing Institutional RWA Footprint

The Mubadala launch arrives during a period of accelerating institutional activity on Solana. Solana logged $10 billion in tokenized stock volume in June 2026 alone, capturing roughly 95% of global on-chain equity trading, and the network's total RWA value reached $3.6 billion by end of June, up 315% since January.

The MCAS-TA deployment adds a dimension to that picture. Where tokenized equities on Solana primarily serve trading demand from retail and institutional accounts, a Mubadala private fund structure is built for a different buyer: qualified institutional allocators seeking on-chain co-investment exposure to alternative strategies they couldn't previously access without a direct fund relationship.

CoinDesk reporting puts the addressable tokenized asset market at $5.5 trillion to $18.9 trillion on-chain by 2030 to 2033, citing industry estimates from project operators and research firms. The Mubadala launch adds a category largely absent from earlier tokenization waves: actively managed private market strategies from a sovereign wealth-affiliated platform, now deployed to production across three major chains.
