Unified Bonding Curve Event Markets: A Multiverse-Inspired Model Without YES/NO Tokens or LPs
By Showerhead, May 2025

Introduction
Prediction markets are powerful tools for aggregating beliefs about uncertain future events. Traditional implementations, however, suffer from fragmented liquidity (YES/NO tokens), complex UX, and capital inefficiencies. Recent innovations like Multiverse Finance reimagine these markets by isolating outcomes in "verses," enabling composable finance with minimal liquidation risk.
Simultaneously, bonding curve-based token launches (e.g.,
pump.fun) have demonstrated the power of single-token markets with self-sustaining liquidity and simple pricing mechanisms.
This paper proposes a unified framework that combines:
Multiverse Finance’s outcome-specific financial isolation
Bonding curve token distribution models (
Pump.fun style)
Synthetic shorting mechanisms for balanced markets
The result is an elegant, capital-efficient event market that avoids YES/NO token splits, external liquidity pools, and global liquidation risks — while supporting lending, leverage, and composability.

Core Concepts
1. Single-Token Event Markets
For each binary event (e.g., "ETH > $5k by Dec 2025"), a single OutcomeToken is created.
Price discovery happens via a bonding curve: early buyers get favorable prices, late buyers pay more.
No separate YES/NO tokens are minted. Market beliefs are reflected in the price of this one token.
2. Synthetic Shorts Replace NO Tokens
Users who believe the event won’t happen can open synthetic short positions:
Borrow OutcomeTokens.
Sell them into the bonding curve.
Lock collateral to cover potential losses.
This synthetic shorting provides the downward pressure traditionally supplied by NO token liquidity.
3. Resolution & Settlement
Upon event resolution:
If the event occurs: OutcomeToken price settles at $1.
If the event fails: OutcomeToken price settles at $0.
Short-sellers’ collateral is used to pay out long token holders in a zero-sum settlement.

Borrowing & Lending Collateral
Inspired by Multiverse Finance, this model enables borrowing against OutcomeToken positions without traditional liquidation risks.
Mechanism Overview
OutcomeToken holders can borrow assets (e.g., USDC) using their tokens as collateral.
Borrow capacity is dynamically adjusted based on the probabilistic price of OutcomeToken.
Liquidations are isolated to the specific event: no global market spillovers.
Short-sellers’ posted collateral can serve as implicit lending liquidity.
Benefits
Borrowing risk is contained within the event market.
No forced liquidations from unrelated price swings.
Creates a self-sustaining credit market inside each event.
Encourages capital efficiency and leverage while maintaining solvency.

Self-Funding Liquidity: No LPs Needed
This model does not require external liquidity pools:
Buyers of OutcomeTokens inject liquidity into the bonding curve.
Short-sellers supply capital through their collateral.
The bonding curve algorithmically balances these forces to create a liquid market.
Liquidity grows naturally with market participation.

Composability & Extensions
This architecture enables:
Leverage: Borrow against OutcomeToken holdings.
Risk Hedging: Express nuanced views via longs/shorts.
Derivatives: Compose with options, vaults, structured products.
On-chain credit markets: Re-hypothecate short collateral for lending.
Further, the framework generalizes to multi-outcome events and can power markets for:
Elections
Crypto price thresholds
Protocol governance decisions
Sports outcomes

Conclusion
By fusing the capital efficiency of bonding curves, the risk isolation of Multiverse Finance, and synthetic shorting mechanics, this unified event market model offers a more elegant and composable alternative to traditional prediction markets.
It simplifies UX, removes the need for LPs, and enables advanced financial primitives — all while ensuring market integrity through outcome-tied settlements.
This is not just a prediction market redesign. It’s a generalized framework for event-driven, self-contained financial universes.

Prediction markets let you bet on outcomes, but so much more is possible.
This paper introduces Multiverse Finance, which splits the financial system into parallel universes so you can short the market today, but only if your candidate is going to lose the next election.
