🔒 HIP-4: The Great Unlock 🔒

Hyperliquid's HIP-4 #upgrade went live on mainnet last week. Most coverage has framed it as "prediction markets on Hyperliquid."
But that framing undersells it considerably. ⭐️ What HIP-4 Actually Is
HIP-4 introduces outcome markets, fully collateralised binary contracts that settle within a fixed range. Each market consists of a Yes side and a No side. settlement converts one to a dollar and the other to zero, depending on the resolution. Prices float between 0.001 and 0.999 during continuous #trading and represent the market's implied probability of the underlying event. No leverage, no funding rate, no liquidation engine. The maximum loss is whatever was paid to enter, and positions are fully collateralised in USDH, Hyperliquid's native stablecoin. The first market is a recurring daily binary settling at 06:00 UTC against BTC's mark price on HyperCore. Users can buy YES or NO shares to bet on the directional movement of BTC’s price. This is standard #prediction market structure. But where it diverges from Polymarket and Kalshi is at the margin layer. Your outcome positions and your #perp positions live in the same account. HyperCore recognises when they hedge each other and reduces your total margin requirement accordingly. Long $BTC perps plus a binary that pays if $BTC drops below a threshold nets out to lower margin than holding either in isolation. That cross-margining is what turns HIP-4 from a Polymarket competitor into a capital efficient risk #trading layer. 🐂 The Four Bull Cases
➡️ Buyback flywheel. Roughly 97% of #protocol fees flow to the Assistance Fund, which executes #HYPE buybacks. Fees from HIP-4 markets feed directly into this. #HYPE holders benefit from #platform usage in a way Polymarket and Kalshi users cannot. ➡️ Composability. #Hyperliquid is the only #crypto venue offering spot, #perpetual futures, and #prediction markets natively on a single execution layer with unified margin. Nobody else matches this. The fee structure reinforces it: opening an outcome position carries no fee, but fees apply on close, burn, or settlement. Volume on settled contracts counts toward protocol-wide fee tiers, meaning active #prediction market traders qualify for lower rates on perps through the same account. ➡️ Infrastructure advantage. Polymarket runs off-chain order matching with on-chain settlement on #Polygon and has publicly said its traction has "massively outpaced" its current infrastructure, with a chain migration named as a priority. HIP-4 launches directly onto Hyperliquid's existing derivatives engine, the same matching engine handling billions in open interest across perps at roughly 200,000 orders per second. ➡️ #Expansion path. Future upgrades can build new primitives on HIP-4. On-chain options are the obvious next step. Some analysts have pointed out that outcome contracts could also #function as insurance, a shipping company buying YES on Strait of Hormuz disruption while running an offsetting oil #perp in the same account. 👀 The Kalshi Connection
Worth noting that John Wang, Kalshi's Head of Crypto, co-authored the HIP-4 proposal alongside Hyperliquid's team and Framework Ventures. While John Wang maintains that his contribution to the proposal was in a personal capacity, many have speculated about a possible collaboration between both companies. If that collaboration pans true, it could bring Kalshi's regulated market design onto Hyperliquid's L1 or seed an on-chain Kalshi spinoff sitting on the same infrastructure., 🔖 Bottom Line: The "prediction markets on Hyperliquid" framing misses the point. HIP-4 is an outcome contract layer that cross-margins with the existing perps engine, feeds the #HYPE buyback flywheel, and sets the foundation for on-chain options. #Hyperliquid does not need to beat Polymarket to win here. It needs HIP-4 to make the rest of the #platform stickier. That is a much easier bar to clear. #cryptofactske
