## Content

**HIP-4 background:** Announced February 2, 2026. Hyperliquid's "outcome contracts" — event-based derivatives that settle at 0 or 1 based on whether a specific real-world event occurs. Fully collateralized, expiry-based, no margin/liquidations.

**Kalshi partnership (announced March 2026):** John Wang, head of crypto at Kalshi, co-authored the HIP-4 proposal with Hyperliquid. This is a regulated DCM providing market design to an offshore decentralized platform.

**Status (April 29, 2026):** HIP-4 on testnet since February 2026. Hyperliquid published fee structure for outcome tokens in late April 2026 (no fees to open, fees on closing/settlement). No mainnet launch date confirmed.

**Competitive context:** Hyperliquid is a major decentralized crypto exchange — 3.3% of Polymarket users also active on Hyperliquid, but those overlapping traders = 12% of Polymarket's total volume (most active speculators have one foot in both).

**Key regulatory structure:**
- Hyperliquid = offshore, decentralized, BLOCKS US users
- Kalshi = CFTC-registered DCM, US users allowed
- The partnership puts Kalshi's market design on Hyperliquid's decentralized infrastructure
- US users access prediction markets via Kalshi; non-US users via Hyperliquid

**From Bloomberg (April 29):** "Kalshi, Polymarket Face New Rival in Crypto's Hottest Exchange" — this is today's Bloomberg story, indicating Hyperliquid is being positioned as competition to regulated US platforms.

**The two distinct structural models:**
1. **Hyperliquid/HIP-4 approach:** "Offshore to avoid US regulation" — explicitly blocks US users, uses external event settlement (0 or 1 on observable external facts)
2. **MetaDAO approach:** Accessible to US users, settles against endogenous TWAP (governance token price), not external observable facts

## Agent Notes

**Why this matters:** HIP-4 is the clearest illustration of the "offshore decentralized" regulatory escape route — the alternative to MetaDAO's "structural distinction from event contracts" route. Both are trying to avoid the DCM registration requirement, but through different mechanisms:
- Hyperliquid: geography + user exclusion (no US users = no US regulatory reach)
- MetaDAO: structural distinction (TWAP settlement ≠ external event = not an event contract)

**What surprised me:** Kalshi's head of crypto co-authored HIP-4. This means the most regulated prediction market platform is simultaneously building the most unregulated one. Regulatory arbitrage at the infrastructure design level.

**What I expected but didn't find:** Any CFTC comment or awareness of the Kalshi-Hyperliquid partnership. If CFTC eventually brings enforcement against Hyperliquid's HIP-4 (for providing access to US users, as has happened with other offshore venues), the Kalshi connection becomes legally awkward.

**KB connections:**
- [[Ooki DAO proved that DAOs without legal wrappers face general partnership liability making entity structure a prerequisite for any futarchy-governed vehicle]] — Hyperliquid's decentralized structure would face same entity wrapper question if CFTC targets it
- [[futarchy-based fundraising creates regulatory separation because there are no beneficial owners and investment decisions emerge from market forces not centralized control]] — MetaDAO's endogenous settlement is structurally different from HIP-4's external event settlement

**Extraction hints:**
1. "Kalshi-Hyperliquid HIP-4 partnership creates an offshore decentralized prediction market infrastructure that separates US regulatory access (via Kalshi DCM) from decentralized on-chain execution (via Hyperliquid) — a different regulatory escape strategy from MetaDAO's endogenous settlement distinction" [confidence: experimental — structure is clear, regulatory outcome is not]
2. "The three distinct regulatory strategies emerging in decentralized prediction market infrastructure are: DCM registration (Kalshi), offshore geographic exclusion (Hyperliquid/HIP-4), and structural event-contract distinction (MetaDAO TWAP endogeneity) — only the third maintains US user accessibility without DCM registration" [confidence: experimental]

**Context:** Bloomberg (April 29) treats Hyperliquid as a competitor to Kalshi/Polymarket. The institutional narrative is "crypto exchange vs. prediction market." The regulatory narrative is different: Hyperliquid is explicitly offshore, which is why it can offer prediction markets without CFTC oversight. MetaDAO has neither offshore structure nor DCM registration — its only regulatory defense is the structural distinction.

## Curator Notes
PRIMARY CONNECTION: MetaDAO conditional governance markets may fall outside the CFTC event contract definition because TWAP settlement against internal token price is endogenous rather than an external observable event
WHY ARCHIVED: HIP-4 + Kalshi creates a natural contrast case: offshore decentralized event contracts (HIP-4) vs. on-chain governance contracts (MetaDAO) — two different structural strategies for avoiding DCM registration; the comparison clarifies why MetaDAO's TWAP endogeneity distinction is substantive, not cosmetic
EXTRACTION HINT: The extractor should focus on the structural comparison between HIP-4 (offshore + external event settlement) and MetaDAO (US-accessible + endogenous TWAP settlement) — this contrast makes the TWAP endogeneity distinction legible to legal practitioners who understand why HIP-4 blocks US users
