Decentralized perpetual futures had a breakout year in 2025. Two platforms tell most of the story, even though they barely compete for the same trade. Hyperliquid became the dominant venue for onchain crypto derivatives, while Ostium built a smaller but fast-growing market for perpetuals on stocks, commodities, indices, and foreign exchange. Comparing their volumes side by side is useful, but only after acknowledging that one is selling crypto leverage and the other is selling a synthetic version of Wall Street.

What each platform actually does

Hyperliquid is a layer-one blockchain built around an onchain order book for perpetual futures and spot trading. The Hyperliquid blockchain is comprised of two components, HyperCore and the HyperEVM, secured by the same underlying consensus mechanism, HyperBFT. Both the algorithm and blockchain are optimized from the ground up to support the unique demands of an L1 blockchain, with the chain currently supporting 200k orders per second. Most of its volume is crypto-on-crypto: Bitcoin was the most-traded digital asset on the platform with $1.16 trillion in volume, followed by Ethereum and Solana with $824.61 billion and $269.94 billion respectively.

Ostium runs on Arbitrum and takes a different angle. The Arbitrum-based protocol offers on-chain perpetual swaps tied to equities, commodities, indices and FX, and has seen $25 billion in cumulative volume with more than 95% of open interest in traditional markets. Rather than bringing tokenized gold or tokenized Apple shares onchain, Ostium uses oracle price feeds to mirror those assets through perpetual contracts settled in USDC. Positions are managed through smart contracts on Arbitrum, with collateral held in a self-custodial wallet.

The headline numbers

The volume gap is enormous in absolute terms, and the chart below shows why a direct comparison can mislead more than it informs.

Hyperliquid closed 2025 with truly large industrial-scale numbers. Its 2025 trading volume hit $2.95 trillion, with daily average transaction volume at $834 million across 198.9 billion executed orders. The platform earned $843 million in revenue and $908 million in fees, with $808 million coming from perpetual contracts. Spot trading volume reached $1.168 trillion.¹ Recent daily figures put Hyperliquid futures at around $6.98 billion in 24-hour volume against roughly $7.6 billion in open interest.

Ostium's totals are smaller but climbing fast. Disclosures from December 3, 2025 said the company has processed $25 billion in cumulative trading volume to date, including $5 billion in metals trading alone.² Open interest on the protocol is a more modest $159 million, with the top open contracts in gold, silver, EUR/USD, copper and the Nasdaq. So Hyperliquid's cumulative 2025 volume runs roughly 118x larger than Ostium's lifetime volume. The absolute gap is real, the comparison is incomplete.

Why the comparison breaks down

The two platforms address different markets, with different reference points for what counts as success.

Hyperliquid is competing for derivatives flow that already exists in crypto. Binance, Bybit, OKX, and dozens of other centralized exchanges process trillions in perpetual volume every year. By that benchmark, Hyperliquid is now a top-tier venue and the dominant decentralized one. Its product expanded into equities late in 2025 through HIP-3, with global equities such as Apple, Nvidia, Amazon, Google, and Tesla. Nvidia was the most traded HIP-3 listing with $1.73 billion in trading volume, while Tesla and Google followed with $1.15 billion and $1.04 billion respectively. Equities are still a side dish there, with HIP-3 generating about $11.01 billion in trading activity for the year against the platform's trillions in crypto perps.

Ostium is competing for traditional retail trading flow that almost never touches crypto rails. Its pitch is the global contracts-for-difference market and offshore FX brokerages. General Catalyst managing director Marc Bhargava said Ostium is "building transparent and resilient infrastructure poised to disrupt the $10 trillion monthly-volume global CFD market."³ The investor framing matters because it sets a different ceiling. Against the CFD market, Ostium's $25 billion is a beachhead, not a final score.

The category Ostium is trying to define

Ostium calls its thesis "perpification" — the idea that derivative exposure to a real-world asset will scale faster than tokenizing the asset itself. The argument is straightforward: a perp only needs a price feed and a liquidity pool, while a tokenized stock or bond needs custodians, transfer agents, and legal wrappers. The category is no longer hypothetical. Real-world asset perpetuals are growing quickly, with daily trading volumes topping $15 billion in early March 2026 — a figure that would have seemed absurd just 18 months earlier when RWA perps represented less than 1% of the derivatives market.⁴

Within that emerging category, Ostium has staked out a leading position. The platform has processed $25 billion in cumulative volume, including $5 billion in metals, with more than 95% of current open interest concentrated in real-world assets. During the most recent gold rally, it accounted for more than half of all on-chain gold perpetuals open interest. Hyperliquid's HIP-3 stocks are direct competition on equities, but Ostium has commodities and FX largely to itself onchain so far.

What the volume numbers do and do not tell you

Three points are worth keeping straight when this comparison shows up online:

• Different denominators. Hyperliquid measures itself against centralized crypto exchanges. Ostium measures itself against CFD brokers and retail FX.
• Different mix. Roughly 99.6% of Hyperliquid 2025 volume was crypto. Roughly 95% of Ostium open interest is non-crypto.
• Different growth shape. Hyperliquid is monetizing scale at $843 million in annual revenue. Ostium just raised a Series A and is still in expansion mode.

If the question is "who has more volume," Hyperliquid wins by a factor of roughly 100. If the question is "who is winning the onchain RWA derivatives race," the answer is Ostium, with Hyperliquid's HIP-3 stack as the most credible challenger. Both can be true at once, and both probably matter for where decentralized derivatives go from here.
