Ostium, a decentralized finance (DeFi) exchange operating on the Arbitrum blockchain, has made a significant leap by becoming the first onchain trading venue to offer equity perpetuals on U.S. stocks, powered by institutional-grade data from Nasdaq. This development marks a pivotal moment in the integration of traditional financial markets with blockchain technology, allowing global traders to access U.S. equities with the advantages of transparency, instant settlement, and self-custody. Since its launch in 2024, Ostium has processed over $50 billion in volume from more than 26,000 traders. The partnership with Nasdaq enhances the credibility of Ostium's offerings, which already included equity perpetuals prior to this announcement. The notional open interest for perpetual futures contracts on the platform stands at about $91.6 million. As interest in equity perpetuals grows, they accounted for nearly 20% of the RWA perpetuals market activity last week. Nasdaq's ongoing strategy to support onchain trading infrastructure, as seen through its recent collaborations, signals a shift towards the tokenization of equity markets, potentially reshaping how traders interact with traditional assets.
