Nansen has expanded its trading platform beyond conventional cryptocurrency markets by integrating Outcome.xyz markets built on Hyperliquid‘s HIP-4 infrastructure, allowing users to trade event-based contracts alongside their existing onchain activity.
The integration brings supported stock and cryptocurrency outcome markets directly into Nansen Trading, with politics and sports markets expected to follow as Outcome.xyz expands its offerings.
Rather than simply tracking the markets, Nansen users can research an outcome, examine onchain positioning and execute a trade without leaving the platform. The company says the integration is part of a broader strategy to move from its roots in blockchain analytics toward an interface where users can “trade everything onchain.”
Nansen’s product changelog shows Outcome.xyz HIP-4 markets went live on its web platform on Aug. 31. Users can discover markets through Nansen’s Token Screener and search functions, inspect them through Token God Mode and then execute trades. Nansen described itself at the time as “one of the first” front ends to support the markets.
The launch comes immediately after one of the biggest changes yet to Hyperliquid’s outcome-market infrastructure.
HIP-4 was introduced to give Hyperliquid a native framework for contracts with discrete outcomes rather than the open-ended price exposure offered by perpetual futures. Outcome contracts can represent questions that ultimately settle to defined results, opening the infrastructure to prediction markets and other bounded-payoff products.
Hyperliquid initially rolled out HIP-4 cautiously. Outcome markets went live on mainnet in May, while offchain-event markets were initially deployed under a validator-governed structure. In July, Hyperliquid announced plans to let outside builders deploy markets themselves using standardized templates approved by validators.
That permissionless phase reached mainnet on Aug. 29. Builders can now create HIP-4 markets from approved templates rather than waiting for Hyperliquid itself to introduce each market. Deployers currently have to stake 500,000 HYPE, with the stake subject to slashing if markets are poorly defined or settled incorrectly.
Outcome.xyz emerged as the first reported third-party venue to deploy through that system, registering its OUT venue as permissionless deployment opened. The new structure has already begun producing competition between deployers over which markets to list and, more importantly, where traders and liquidity ultimately congregate.
Early data suggests the opening has materially increased activity. Research published after the Aug. 29 upgrade found HIP-4 daily volume rose from an average of about $545,000 during the first 28 days of August to $1.63 million on Aug. 30 and $1.97 million on Aug. 31. Outcome accounted for roughly 70% of the latter session.
More recent onchain tracking shows HIP-4 generated about $28.4 million in notional volume over the 30 days through Sept. 7, across more than 441,000 trades and almost 4,000 unique traders.
For Nansen, the attraction goes beyond adding another tradeable product.
The company built its name around wallet labeling and “Smart Money” analytics, tracking the behavior of hundreds of millions of blockchain addresses. It has increasingly connected that data with execution, including crypto spot and perpetual trading.
Outcome markets add another layer because wallet positioning itself can become part of the information traders use when deciding whether to take a position.
“Prediction markets are having a real moment for a reason. People enjoy forming a view and putting it to the test,” Nansen co-founder and CEO Alex Svanevik said.
He said users could examine who was positioning around particular outcomes and where the strongest conviction appeared before acting on that information directly through Nansen.
Outcome.xyz also sees distribution as central to the emerging market. Its co-founder Ahmed said that for a new trading category, distribution could be as important as the underlying market design, making a research platform such as Nansen a natural route to traders.
Outcome has also developed tooling specifically around HIP-4. Its public SDK supports market discovery, order books, live prices, trading, wallet activity and market settlement, illustrating how the project is positioning itself as both a venue and an infrastructure layer around Hyperliquid’s outcome system.
Nansen is offering an additional incentive to bring users into the markets. Eligible traders using qualifying Outcome.xyz contracts through Nansen can participate in a $1 million rewards pool, subject to the campaign’s eligibility requirements.
The Bigger Battle Is Becoming Distribution, Not Just Market Design
Nansen adding HIP-4 markets looks like a product integration, but the more interesting development is what it says about the direction of onchain trading.
Crypto applications have spent years separating themselves into categories: decentralized exchanges for tokens, perpetual venues for leverage, analytics platforms for research and prediction markets for events.
Hyperliquid is steadily undermining those boundaries.
HIP-3 already allowed outside builders to deploy perpetual markets, while HIP-4 now gives builders infrastructure for discrete outcomes. Nansen is doing something similar at the interface level by combining research and execution instead of asking users to move between several applications.
That matters because once the underlying market infrastructure becomes relatively open, distribution becomes scarce.
Two builders can theoretically create similar HIP-4 contracts. What is much harder to duplicate is an existing audience of traders, recognizable analytics, wallet intelligence and a front end those traders already use. Nansen therefore gives Outcome something potentially more valuable than another place to display a market: an acquisition channel.
The same logic works in reverse. Outcome gives Nansen a reason for users to remain inside its product after discovering a trade rather than taking that information to another venue.
There is also a potentially powerful network effect. Outcome markets need liquidity to produce meaningful probabilities and efficient execution. Traders naturally prefer deeper markets, and deeper markets attract still more traders. If a small number of front ends direct substantial order flow toward particular HIP-4 deployers, the supposedly permissionless market could still consolidate economically around a few dominant venues.
That makes the early Outcome lead worth watching rather than assuming it is permanent.
Through Sept. 1, independent onchain data attributed roughly $6.6 million of permissionless HIP-4 volume to Outcome’s venue, representing more than 99% of volume between the two registered venues tracked at the time.
The more consequential expansion, however, is beyond crypto.
Stock-linked outcomes place HIP-4 closer to traditional financial products, while future politics and sports markets would place it directly alongside the categories that helped make Polymarket and Kalshi mainstream names. Those additions can also create substantially different regulatory questions depending on the market and jurisdiction.
For Hyperliquid, that means the opportunity is much larger than adding another type of crypto derivative, but so is the complexity.
For Nansen, the bet is simpler: if more assets, events and financial opinions become tradeable onchain, the winning interface may be the one that helps a trader understand the opportunity and execute it without caring which traditional market category it once belonged to.
The Outcome.xyz integration is an early test of whether that “everything onchain” model can move from slogan to actual trader behavior.
