Nasdaq and Talos target $35B in trapped collateral with TradFi-crypto integration

Nasdaq and Talos have integrated legacy financial infrastructure into crypto trading systems to unlock $35 billion in trapped collateral. The partnership connects Nasdaq's Calypso risk platform and Trade Surveillance technology with Talos's institutional liquidity network. The move addresses capital inefficiency caused by fragmented settlement layers and disconnected risk systems. Institutional collateral sits idle in non-interest-bearing buffers, whilst moving traditional assets like Treasuries to cover crypto margin calls requires T+1 settlement and manual reconciliation. Talos clients, including hedge funds and brokers, now access unified workflows managing tokenised real-world assets alongside crypto and traditional equities. Nasdaq's Trade Surveillance engine enables real-time detection of market manipulation across venues, bringing regulatory-grade audit trails to digital asset trading. The integration eliminates pre-funding requirements and capital mobility bottlenecks that have slowed institutional adoption.

SEC approves Nasdaq plan to settle stock trades on blockchain

The SEC has approved a plan allowing certain Nasdaq-listed securities to trade in tokenised form, settling on blockchain rather than through traditional book-entry systems. This marks the first time US regulators have formally integrated blockchain technology into core stock trading infrastructure. Tokenised shares will trade on the same order book as regular shares, with identical tickers, prices and rights. The only difference is settlement method, which uses blockchain tokens rather than the Depository Trust Company's traditional ledger system. Existing surveillance and settlement timelines remain unchanged. The approval follows Nasdaq's September filing and reflects the SEC's more receptive stance towards digital asset integration. Intercontinental Exchange, owner of the New York Stock Exchange, is pursuing similar initiatives through investments in crypto exchange OKX, intensifying competition between the two largest US exchanges.

Nasdaq partners with Kraken parent to develop tokenised equity design for on-chain trading

Nasdaq is developing a new design for tokenised equities that gives publicly traded companies greater control over their shares in token form, including proxy-related matters, corporate actions and governance rights. The exchange has partnered with Payward, Kraken's parent company, to build a gateway enabling tokenised equities to move between regulated and on-chain markets. The initiative follows Nasdaq's September filing with the Securities and Exchange Commission proposing to enable equity securities to trade on its markets and settle in token form through the Depository Trust & Clearing Corp. Separately, Nasdaq announced a partnership with Seturion, Boerse Stuttgart Group's pan-European settlement platform, to connect its European trading venues for tokenised securities trading. The New York Stock Exchange is pursuing a similar blockchain-based venue for round-the-clock trading of tokenised stocks and exchange-traded funds.

The ceremony included Lieutenant Governor Dan Patrick, Nasdaq Chair Adena Friedman and Texas business leaders. Nasdaq launched Nasdaq Texas in November, a dual listing venue expanding services statewide. Under Abbott's tenure, Texas has attracted over 325 corporate headquarters and hosts 54 Fortune 500 companies. As the world's eighth-largest economy, the state employs the nation's largest financial services workforce, surpassing New York. Nasdaq established its regional headquarters in Dallas last March.
