Ostium has become the first onchain trading venue to offer equity perpetuals on individual U.S. stocks using Nasdaq data, giving global traders blockchain-based access to Wall Street equities. Built on Arbitrum, the DEX specializes in perpetual futures tied to real-world assets and has processed more than $50 billion in cumulative volume from over 26,000 traders since its 2024 launch, with roughly $91.6 million in notional open interest per DefiLlama.
Why it matters
Ostium already offered equity perps before Tuesday — the Nasdaq partnership layers official, institutional-grade price data on top. That distinction matters for a sector where the integrity of the underlying reference price is the whole game. Equity perpetuals have already grown to nearly 20% of the RWA perps market's $75 billion in weekly activity, per Stork Labs, and the product class is increasingly setting prices for names like Cerebras (CBRS) before their Nasdaq debut.
Market impact
The deal is Ostium's second Nasdaq-adjacent tie-up in two months and follows Nasdaq's March agreement with Payward (Kraken's parent) to build tokenized-equity infrastructure. Read together, the cadence suggests Nasdaq is methodically positioning itself in onchain equity rails rather than running a one-off experiment. The credibility lift could help Ostium take share in a market where Hyperliquid's commodities and equity books are already dominating weekend volume — and where global, broker-gated access to U.S. names is the wedge DEXes keep hammering on.
Frequently asked questions
-
What did Ostium actually launch?
Ostium became the first onchain trading venue to offer equity perpetuals on individual U.S. stocks using official Nasdaq data. The DEX was already offering equity perps — the Nasdaq tie-up layers institutional-grade price data on top of the existing product.
-
How big is Ostium and what chain is it on?
Built on Arbitrum, Ostium has processed more than $50 billion in cumulative volume from over 26,000 traders since launching in 2024. Notional open interest is around $91.6 million, according to DefiLlama.
-
How fast is the equity perpetuals market growing?
Equity perpetuals already account for nearly 20% of the RWA perps market, which itself cleared $75 billion in weekly activity, per Stork Labs. Stork Labs also noted that pre-IPO perps in Cerebras (CBRS) priced the stock almost perfectly hours ahead of its Nasdaq opening trades.
-
Is this Nasdaq's first move into onchain trading?
No — Nasdaq struck a separate deal with Payward, the parent of Kraken, in March to develop infrastructure connecting tokenized equity markets with decentralized blockchain networks. The Ostium tie-up is the second partnership in two months, suggesting a deliberate strategy.
-
Why does the Nasdaq data feed matter for a DeFi perp?
Perpetual futures settle against a reference price, so the integrity of the underlying data feed is the product. A Nasdaq-grade feed gives Ostium institutional credibility and removes a key objection for traders comparing onchain equity perps to brokered access.
