Reroll

Reroll is a crypto betting platform built on Hyperliquid, leveraging the chain's high-performance order book and HIP-4 binary settlement contracts. Its core business revolves around event-based prediction markets, where users trade fully collateralized positions that settle to 0 or 1 based on verifiable outcomes.

Its competitive edge lies in Hyperliquid's shared liquidity and builder ecosystem. By deploying on Hyperliquid, Reroll taps into deep perp liquidity and the same account environment as major markets, avoiding fragmentation. The platform also benefits from HIP-3's open deployment model, allowing third-party market makers to earn up to half of trading fees, which incentivizes liquidity provision.

The market pain point it addresses is the opacity and high friction of traditional betting platforms. On-chain settlement provides transparency, while Hyperliquid's infrastructure offers speed and low latency comparable to centralized exchanges. Additionally, the integration with RWA perps (e.g., oil, gold, Nvidia, SpaceX) expands the range of tradeable events beyond sports.

In the past six months (March 13 to September 13, 2026), Hyperliquid's HIP-4 open rollout on August 29 tripled daily volume from ~$545K to $1.97M within three days, with rolling volume reaching $2.75M. RWA perps open interest hit a record $3.6B, surpassing BTC as the largest market on the platform. However, growth has been highly concentrated—one entity (Trade.xyz) controls over 90% of HIP-3 open interest, and a single operator dominates HIP-4 activity, raising centralization risks. Platform revenue has also declined for four consecutive quarters, from a $357M peak in Q3 2025 to $202M in Q2 2026, despite rising trading volume, as fee-sharing with third-party deployers reduces retained earnings. Regulatory uncertainty remains for event contracts, particularly sports betting, which faces potential legal scrutiny under US federal law.
