Hyperliquid's HIP-4 event contract product went live, logging 6.05 million contracts (notional above $6M) on its first trading day — roughly 0.7% of total prediction-market volume. For context, Kalshi cleared 546M contracts and Polymarket hit 190M on the same day.
Why it matters
The number is small, but the venue isn't. Hyperliquid built its user base around perpetual futures, not event contracts, and HIP-4 marks its first step into the prediction-market category. Rolling a new product into an existing high-volume perps book is structurally different from spinning up a standalone prediction venue — the distribution and the matching engine are already in place, so the marginal cost of incremental contracts is low even if early-day flow is modest.
Market impact
First-day share of 0.7% is not a threat to Kalshi or Polymarket on its own, but the launch tests whether Hyperliquid's perps-native audience will treat event contracts as a real allocation. Worth watching: how HIP-4 volume tracks over the next two to four weeks relative to the launch baseline, and whether the platform layers more contract types — political, macro, crypto-native catalysts — on top of the current set.
