A DeFi exchange becomes the first to offer equity perpetuals powered by Nasdaq data

Ostium, an Arbitrum-based DeFi exchange, has become the first onchain venue to offer equity perpetuals on individual U.S. stocks using Nasdaq-provided market data. The Nasdaq tie-in supplies institutional-grade pricing and legitimacy that could boost liquidity, attract global traders seeking 24/7 exposure to U.S. equities, and accelerate tokenized-stock market development. Ostium has processed over $50 billion in cumulative volume since 2024, with about $91.6 million in notional open interest. Industry data show equity perpetuals now represent nearly 20% of a $75 billion weekly RWA perps market, suggesting strong demand and improved onchain price discovery. Nasdaq’s repeated deals with onchain venues indicate a broader strategic push into tokenized equity infrastructure, a development that may shift how traders access and price traditional assets around the clock.
