Trade: Rocket Lab’s Neutron Rocket Launch by December 31?
Resolution criteria on PolyGram: If Rocket Lab’s Neutron rocket successfully launches from its launch pad by December 31, 2026, 11:59 PM ET, this market will resolve to “Yes”. Otherwise, this market will resolve to “No.” The outcome of any launch will be corroborated by examining official video provided by Rocket Lab (https://www.youtube.com/@RocketLabCorp), as well as secondary video feeds and/or written reports if necessary. Any subsequent anomaly (e.g., explosion or failed ascent) after the initial liftoff will have no bearing on the outcome. Any name change or rebranding of the Neutron vehicle will have no bearing on the market’s resolution.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

| Rocket Lab’s Neutron Rocket Launch by December 31? | 53% YES | 47% NO |
Market context
Rocket Lab aims to conduct the maiden flight of its Neutron medium-lift launch vehicle by the end of 2026. The company has been developing this larger rocket to complement its existing Electron vehicle, targeting commercial and government payloads in the 8-tonne-to-orbit class. The market currently prices a 53% probability of successful liftoff occurring within the settlement window, reflecting meaningful uncertainty about whether development and launch infrastructure will be ready within the timeframe.
Historical precedent suggests caution around first-flight timelines for new orbital rockets. SpaceX's Falcon 1 experienced multiple delays before its 2006 debut; Blue Origin's New Shepard took years longer than initially projected; Axiom Space's commercial modules faced repeated pushbacks. Rocket Lab itself has demonstrated execution capability with Electron, though Neutron represents a substantially larger engineering undertaking with new engines and structures. The current 53% probability on Polymarket's order book reflects this tension between Rocket Lab's track record and the inherent risks of first-flight vehicles.
Key catalysts include Rocket Lab's official development milestones and facility construction progress at its Virginia launch site. The company has stated intentions to conduct Neutron's maiden flight in 2024, though this has already slipped. Recent announcements regarding engine testing completion and pad construction status will likely move the market; traders should monitor quarterly earnings calls and press releases for revised timelines. Regulatory approvals from the Federal Aviation Administration and any supply-chain disruptions affecting engine or avionics production represent additional dependencies that could compress or extend the 2026 window.

How this market resolves
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
How to trade this market step by step
The mechanics for trading "Rocket Lab’s Neutron Rocket Launch by December 31?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
- Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
- Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
- Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
- Size your position. If you stake 100 USDC at 53% YES, you'll receive shares that pay $189 if YES resolves true — a 89% gross return. If NO resolves, your shares are worth $0.
- Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
- Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.
How active is this market?
$67 in lifetime turnover and $210 of resting liquidity puts this market in the below the median by volume for science contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
