The prediction markets sector, which exploded to $63.5 billion in trading volume in 2025, is about to get a major new player. Hyperliquid, the decentralized exchange known for its lightning-fast perpetual futures, has unveiled plans to integrate event-driven wagering directly into its platform—challenging incumbent giants Polymarket and Kalshi with a disruptive “zero-fee to open” model.
As the sector continues to expand at breakneck speed—with Bernstein projecting annual volumes could hit $1 trillion by 2030—Hyperliquid’s move signals a significant shift in how traders might engage with real-world event contracts.
The $63 Billion Boom
The timing of Hyperliquid’s entry is no accident. The prediction market industry has seen a dramatic acceleration, with combined volume on Polymarket and Kalshi already exceeding 60 billion in the first months of 2026 surpassing the entire total of 2025. Bank of America has described Kalshi as one of the fastest growing non−AI companies in the U.S., with weekly trading volume surging from $100 million a year ago to over $3 billion today.
While sports contracts currently dominate accounting for more than 60% of trading volume, analysts expect institutional interest in economic, political, and macroeconomic contracts to drive the next wave of growth. “We expect the institutional market to develop around economics, business and political contracts, as investors seek more direct and discrete exposure to events,” wrote Bernstein analyst Gautam Chhugani.
Hyperliquid’s Zero-Fee Gambit
Hyperliquid’s strategy revolves around a fee structure designed to lower barriers to entry. Under the proposed HIP-4 upgrade, which introduces “outcome tokens” for binary event contracts, opening a position costs nothing. Fees are only applied when a trader closes or settles a trade.
This model stands in stark contrast to Polymarket, which recently moved away from a zero-fee structure and is now generating an estimated $420 million in annual recurring revenue.
Additional incentives sweeten the deal. Traders using Hyperliquid’s “aligned quote tokens” benefit from 20% lower taker fees and 50% higher maker rebates compared to standard rates. The full fee formula has been published for developers, signaling Hyperliquid’s commitment to transparency as it builds out the infrastructure.
A Multi-Asset Trading Hub
What makes Hyperliquid a credible threat to Polymarket and Kalshi isn’t just the fee structure—it’s the platform underneath. Hyperliquid has rapidly evolved from a niche crypto derivatives venue into one of decentralized finance’s most ambitious marketplaces, offering contracts linked to oil, gold, silver, and U.S. equities .
HIP-4 would allow users to trade binary contracts on real-world events alongside existing perpetual and spot positions in a single margin account. This portfolio approach is a key differentiator. “Sophisticated traders will be able to take advantage of portfolio margin and figure out ways to generate alpha from these two different market types,” said Sunny Shi, an investor at crypto fund Syncracy Capital, according to Bloomberg.
The competition is moving in both directions. As Hyperliquid pushes into prediction markets, Polymarket announced that perpetual trading is “coming soon”—bringing the two platforms into closer rivalry.
Stress-Tested and Ready
Hyperliquid has already demonstrated its ability to handle real-world event trading under pressure. In February, during the Iran crisis, oil-linked contracts on the platform saw more than $1 billion in single-day trading volume while traditional commodity markets were closed. This stress test provided an early validation of the platform’s capacity to price geopolitical risk in real-time.
The overlap between user bases is already evident. On-chain research reveals that while only 3.3% of Polymarket users are also active on Hyperliquid, those overlapping accounts contribute approximately 12% of Polymarket’s total volume—suggesting that the most active speculators are ready to consolidate their activity.
The Regulatory Divide
Hyperliquid’s entry highlights a fundamental tension within the prediction market industry. Kalshi and Polymarket have spent the past two years pursuing regulatory legitimacy—Kalshi winning CFTC approval, Polymarket returning to the U.S. market, and major brokerages like Robinhood and Interactive Brokers integrating prediction products .
Hyperliquid cuts against that grain. As an offshore, decentralized exchange that restricts U.S. users, it can move faster and offer products that regulated platforms cannot . HIP-4 was co-authored by John Wang, head of crypto at Kalshi, following a partnership announced in March—suggesting that even established players see value in decentralized infrastructure .
What’s Next
Outcome tokens are currently live on testnet, with no official mainnet launch date confirmed . However, the publication of the fee structure signals that launch is imminent.
Industry participants expect early adoption to be gradual, with activity concentrated outside the U.S. in markets that have not had access to mainstream prediction platforms. “Historically prediction markets have been very centered around sports, geopolitical events and elections, with most of the activity coming via sports,” said Rajiv Patel-O’Connor, a partner at Framework Ventures.
As the prediction market sector barrels toward $240 billion in 2026 volume and a projected $1 trillion by 2030, Hyperliquid’s zero-fee, multi-asset approach represents a formidable challenge to Polymarket’s throne. Whether traders will prefer regulated simplicity or decentralized flexibility remains to be seen—but one thing is certain: the prediction market wars have entered a new phase.
