Ostium, a decentralized perpetuals exchange, reached a milestone in onchain trading on Monday, May 18, 2026, by announcing a partnership with Nasdaq to power its equity perpetual products with official institutional data. This integration makes Ostium the first onchain trading venue to offer individual U.S. stock perpetuals backed by Nasdaq’s market data feeds. On Tuesday, May 19, 2026, Ostium engaged its community by asking, “What equities would you like to trade?” as it moved forward with the offering.
The deal aims to dismantle long-standing barriers to entry in traditional finance. “Access to U.S. markets has historically been fragmented, permissioned, broker-gated, and limited by geography,” Ostium stated in a LinkedIn post. By utilizing blockchain rails, specifically the Arbitrum layer-2 network, the exchange provides global traders with transparency, instant settlement, and self-custody. On Monday, May 18, an advertisement even appeared on the facade of the Nasdaq building in Times Square, identifying Ostium as a “Nasdaq Data Client.”
Founded by Harvard alumni Kaledora Kiernan-Linn and Marco Antonio Ribeiro, Ostium has already established a footprint in the derivatives market. Before this partnership, the platform processed over $50 billion in cumulative volume from more than 26,000 traders. While investors were already trading Ethereum-based decentralized assets and other perpetuals, the Nasdaq link provides a level of data integrity and reliability that was previously difficult to find in the DeFi space.
Institutional data meets decentralized futures
While Ostium already offered equity perpetuals, the Nasdaq integration brings official, institutional-grade data to the platform’s pricing models. Kaledora Kiernan-Linn, Ostium’s CEO, noted that the process was not an overnight shift. “It took months of discussion and downstream engineering effort around data integrity, security, display policies and more to get us here,” she explained. This focus on reliability is crucial for a platform that allows leveraged bets on real-world assets directly from a crypto wallet.
The platform’s financial backing reinforces its growth strategy. Ostium has raised $27.8 million in total funding, including a $20 million Series A round co-led by General Catalyst and Jump Crypto. Other backers include LocalGlobe, Susquehanna, and Alliance DAO. Currently, the platform maintains a notional open interest of roughly $91.6 million, according to data from DefiLlama. This capital supports an expanding range of perpetual futures tied not only to stocks but also to equity indexes, currencies, and commodities.
Rapid growth in the RWA perpetuals market
The demand for onchain exposure to traditional assets, often called real-world assets (RWA), is rising. According to data from Stork Labs, equity perpetuals accounted for nearly 20% of RWA perpetual activity last week, a market totaling over $75 billion. Traders are increasingly looking for ways to gain exposure to Wall Street when traditional exchanges are closed. Furthermore, these products are assisting in price discovery; for instance, pre-IPO perpetuals for Cerebras Systems (CBRS) priced the stock accurately hours before its Nasdaq debut.
The competition in this niche is heating up. Coinbase recently launched perpetual futures for U.S. equities for its non-U.S. users, and Monday Trade, built on Monad, launched trading for tokenized stocks in April. Despite the presence of these players, crypto liquidations and macro volatility often push traders toward the perceived stability of established equity markets. Ostium’s direct tie to Nasdaq data gives it a distinct branding advantage in this crowded field.
Nasdaq builds tokenized equity infrastructure
For the world’s second-largest stock exchange, this partnership is a calculated move into the digital asset sector. It follows a separate deal in March 2026 with Payward, the parent company of Kraken, to build infrastructure connecting tokenized equity markets with decentralized networks. Two such partnerships in three months suggest Nasdaq is executing a deliberate strategy to support the growing onchain trading market rather than conducting a one-off experiment.
The successful deployment of this infrastructure hints at a coming shift in how global equities are traded. While the long-term adoption by the wider trading community remains uncertain, the arrival of institutional data on a decentralized exchange marks a significant professionalization of the sector. For now, Ostium is focused on liquidity and accessibility, providing a bridge between the decentralized web and the world’s most prominent equity markets.
