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

"What equities would you like to trade?" Ostium asked its community on Tuesday as it announced becoming the first onchain trading venue to offer equity perpetuals trading powered by Nasdaq data.

"Access to U.S. markets has historically been fragmented, permissioned, broker-gated, and limited by geography," the decentralized exchange (DEX) said in a post on LinkedIn. "Traders worldwide can now gain exposure to U.S. equities on Ostium with the benefits of blockchain rails: transparency, instant-settlement, and self custody."

It added that the tie-up will help unlock access to global financial markets and boost liquidity on the platform. It is worth noting that Ostium already offered equity perps on its platform before Tuesday's announcement. The Nasdaq partnership only adds official, institutional grade data.

Ostium is built on Arbitrum, an Ethereum layer-2 blockchain. It lets traders take leveraged bets on real-world assets directly from a crypto wallet. While most DEXes focus exclusively on cryptocurrency trading, Ostium specializes in perpetual futures tied to stocks, equity indexes, currencies and commodities.

The exchange has processed over $50 billion in cumulative volume across more than 26,000 traders since its 2024 debut, according to its website. The notional open interest, the dollar-value of the number of active perpetual futures contracts, is about $91.6 million, according to data source DefiLlama.

Ostium's announcement arrives as crypto traders increasingly gravitate toward traditional market assets such as gold, silver, oil, and U.S. stocks, using onchain perpetuals to gain exposure around the clock when conventional exchanges are closed.

Equity perpetuals are growing and accounted for nearly 20% of the RWA perps market activity of over $75 billion last week, according to data source Stork Labs. These products are also helping in price discovery.

"Pre-IPO perps in CBRS (Cerebras Systems) priced the stock almost perfectly in hours ahead of its opening trades on the Nasdaq," Stork Labs said.

Hyperliquid, the leading decentralized perpetual exchange, has seen this shift play out in recent months, with commodities and equity futures dominating its top markets by volume and open interest over weekends.

The added credibility from the Nasdaq link may help Ostium capture a share of this booming demand for onchain macro exposure.

The announcement also reflects Nasdaq's broader push into onchain markets. In March, the exchange operator struck a separate deal with Kraken's parent company, Payward, to develop infrastructure to connect tokenized equity markets with decentralized blockchain networks.

Ostium's partnership is the second in two months, suggesting Nasdaq is building a deliberate strategy around onchain trading infrastructure rather than making a one-off bet.

Whether traders worldwide will actually use a DeFi protocol to trade Nasdaq-listed stocks at scale remains to be seen.

But for one of the world's most established financial market operators, putting its data behind an onchain venue is a meaningful signal that the tokenization of equity markets is no longer a distant experiment.
