How Bubblegum Works

The mechanics behind Bubblegum — bonding curves that feed prediction markets, two independent price axes, and automatic graduation to permanent liquidity.

How Bubblegum Works

Bubblegum wires together two DeFi primitives — a bonding curve and a prediction market AMM — into a single atomic system. This page explains how they connect.

The Architecture

Every Bubblegum market consists of two linked components:

┌─────────────────────┐         ┌─────────────────────┐
│   BONDING CURVE     │         │   PREDICTION MARKET  │
│                     │         │   (CPMM)             │
│   SOL ←→ $TICKER    │────────→│   $TICKER ←→ YES/NO  │
│                     │         │                      │
│   Determines:       │         │   Determines:        │
│   Token price       │         │   Outcome odds       │
│   Market depth      │         │   YES/NO prices      │
└─────────────────────┘         └──────────────────────┘

When you buy YES on a Bubblegum market, two things happen in a single transaction:

1. Your SOL enters the bonding curve and buys $TICKER
2. That $TICKER flows into the prediction market and mints YES tokens for you

You never touch $TICKER directly. From your perspective, you’re just buying YES with SOL. But under the hood, every trade simultaneously:

• Moves the token price on the bonding curve
• Moves the outcome odds on the prediction market
• Deepens the liquidity available for future traders

The Bonding Curve

The bonding curve is a constant-product automated market maker that prices $TICKER against SOL. It works like any bonding curve you’ve used before:

• Early buyers get more tokens per SOL (price starts low)
• Each buy pushes the price up (constant product math)
• Sells push the price back down (fully reversible)
• No external liquidity needed — the curve IS the market maker

The curve launches with virtual reserves that provide initial depth. As real SOL flows in, the price rises along a predictable curve. Every market uses the same curve parameters, so pricing behavior is consistent and predictable across all Bubblegum markets.

What the Curve Controls

The bonding curve determines:

• $TICKER / SOL price — how expensive the market’s token is
• Market depth — how much SOL is backing the prediction market
• Graduation progress — how close the market is to graduating

It does NOT determine:

• YES/NO odds (that’s the prediction market’s job)
• Who wins at settlement (that’s the oracle’s job)

The Prediction Market (CPMM)

The prediction market uses a Virtual Liquidity CPMM — the same constant-product mechanism used in PNP’s PAMM, adapted for Solana with SPL tokens.

When the market launches, a portion of the token supply is deposited into the CPMM as initial reserve. This creates a 50/50 starting point for YES and NO odds.

As traders buy YES or NO:

• Buying YES increases the YES price and decreases NO
• Buying NO increases the NO price and decreases YES
• Prices always sum to 1.00 (100%)

The CPMM uses virtual reserves derived from on-chain state — no LP tokens, no external pool. The reserve grows as more $TICKER enters from bonding curve trades, which means liquidity depth increases with trading activity.

Price Discovery

Both prices (token and outcome) are discovered independently:

A whale buys a lot of YES	Token price goes up (SOL entered the curve). YES odds go up (CPMM shifted).
Equal YES and NO buying	Token price goes up (SOL entered). Odds stay near 50/50 (balanced CPMM).
Someone sells all their YES	Token price goes down (SOL left the curve). YES odds go down.

This means you can express nuanced views:

• “This question is important but I don’t know the answer” → buy $TICKER, don’t trade YES/NO
• “I’m sure about the outcome but the market is overhyped” → sell $TICKER, buy the outcome you believe in
• “I’m bullish on everything” → buy YES with SOL (naturally does both)

Graduation

When enough SOL has entered the bonding curve, the market graduates. This is a one-time, irreversible transition.

What Happens at Graduation

1. The bonding curve locks — no more curve trades
2. A reserved portion of $TICKER supply pairs with the collected SOL
3. Together they seed a permanent AMM pool with locked liquidity
4. $TICKER now trades freely on the open market

After Graduation

• $TICKER trades on its own AMM pool — anyone can buy/sell freely
• The prediction market keeps running — YES/NO trading continues until settlement
• Users can buy $TICKER on the open market and route it into the CPMM for directional bets
• The token lives on even after the prediction market resolves

Why Graduation Matters

Graduation creates a permanent secondary market for the token. Unlike traditional prediction markets where the market disappears after resolution, Bubblegum markets leave behind a tradeable on-chain token. The graduated AMM pool has its liquidity permanently locked — it can never be rugged or drained.

The Full Lifecycle

1. CREATION
   Creator submits a question + ticker
   → Token mint, bonding curve, and prediction market created atomically
   → Market opens at 50/50 odds

2. CURVE PHASE
   Traders buy YES/NO with SOL
   → SOL enters bonding curve → $TICKER flows to CPMM → YES/NO minted
   → Token price and odds move independently
   → Curve progress bar fills toward graduation

3. GRADUATION
   Bonding curve reaches threshold
   → $TICKER + SOL seed a permanent AMM pool
   → Liquidity locked forever
   → $TICKER trades freely

4. POST-GRADUATION
   Prediction market keeps running
   → Traders buy/sell YES/NO through the AMM pool
   → $TICKER is also tradeable independently

5. SETTLEMENT
   After the market's deadline, the outcome is declared
   → Winners redeem their YES/NO tokens for $TICKER from the CPMM
   → A portion of remaining $TICKER goes to the creator
   → A portion is burned (deflationary)
   → $TICKER continues trading on its AMM pool

Why This Design Works

The bonding curve solves the cold-start problem. Traditional prediction markets need someone to put up capital before trading can begin. Bubblegum’s curve provides liquidity from the first trade — no subsidies, no market makers, no manual seeding.

The two-axis design creates a natural attention market. Token price acts as a proxy for how much the world cares about a question. This is information that traditional prediction markets can’t capture — they only tell you the odds, not how important the question is.

Graduation creates permanence. The token outlives the prediction. Communities can form around tokens. Resolved markets leave behind tradeable artifacts. This turns prediction markets from ephemeral events into lasting on-chain assets.
