For the past two years, the prediction market space belonged almost entirely to two players: Kalshi and Polymarket. That era may be ending. Hyperliquid, a decentralized cryptocurrency exchange that quickly became one of the busiest places to trade digital assets, wants to get into the space. Its approach is different enough to really change how the competition works.
What Hyperliquid Is Actually Proposing
The idea, which is called HIP‑4 and is currently being tested by the public, would let traders bet on what will happen in real life right on Hyperliquid's platform. The structure of the contract is simple. For example, a market predicting whether US inflation in July will exceed 3.5% would produce two tokens, one for each outcome. People who trade take a side, and once the winner is known, the winning token settles at a set value.
That sounds a lot like what Polymarket and Kalshi already do. But the situation changes it in a real way.
Hyperliquid isn't starting from scratch to make prediction markets and hope that people will want to use them. It already has one. At the moment, the platform handles Bitcoin positions, commodities, and equity‑linked contracts. During the Iran crisis, oil‑linked contracts saw over $1 billion in volume in a single day, making them one of the first ways that traders priced geopolitical risk in real time while traditional markets were closed.
Prediction markets dropped, so the ecosystem wouldn't need to find users. They'd already be there.
The Convergence Nobody Saw Coming
What makes this moment unusual is that the competition is running in both directions simultaneously. As Hyperliquid moves into prediction markets, Polymarket and Kalshi have been looking into perpetual futures and other derivatives. These are products that would be similar to the multi‑asset trading that Hyperliquid already provides.
The result is a slow‑motion collision. Prediction market platforms are becoming more like crypto exchanges, and crypto exchanges are becoming more like prediction markets. The category lines that once separated them are dissolving.
Sunny Shi, an investor at crypto fund Syncracy Capital, put it plainly: sophisticated traders would be able to combine portfolio margin across both market types in ways that simply aren't possible on Polymarket or Kalshi today, where the experience remains largely single‑sided betting.
The Regulatory Wrinkle
There's a tension worth flagging. The prediction market industry has spent the last two years working to become regulated. In that time, Kalshi got approval from the CFTC, Polymarket came back to the US, Washington warmed up to the sector, and venture capital poured into platforms that were building within the framework. Hyperliquid goes against that: it's a decentralized, offshore exchange that doesn't let people from the US use its platforms.
That difference is important, both in the real world and in terms of strategy. Kalshi currently holds roughly 90% of the US prediction market share and was recently valued at $22 billion. Even though Polymarket has had weekly trading volume of more than $2 billion for eight weeks in a row, it is reportedly in talks to raise money at a $15 billion valuation. This difference in valuation shows how important US market access is to regulators and investors.
The Bigger Picture
The overlap between user bases is already visible. On‑chain data shows that about 3.3% of Polymarket users are also active on Hyperliquid. However, those shared traders only make up about 12% of Polymarket's total volume, which means that the most active speculators are already present in both worlds.
The prediction market land grab is no longer a two‑horse race. The question now is whether the regulated, US‑focused incumbents can maintain their position against a platform that's already where the volume is.
