Trade: Will Zendaya and Tom Holland get married by December 31?

Market context

Zendaya and Tom Holland, who have been in an on-and-off relationship since 2016 and confirmed their romance publicly in 2021, would need to marry within the next two years for this market to resolve affirmatively. The couple has maintained relative privacy regarding their relationship timeline, with neither party having publicly discussed engagement or marriage plans as of late 2024. Holland has occasionally referenced wanting a family in interviews, whilst Zendaya has prioritised her acting career, which has expanded significantly with major film commitments.

Celebrity engagement-to-marriage markets typically reflect baseline probabilities around 40–50% for couples in committed long-term relationships, adjusted upward for public statements or observable relationship milestones. The current 68% implied probability on Polymarket's order book suggests traders are pricing in either a higher-than-baseline conviction that an engagement announcement is imminent, or a belief that the couple's relationship stability and public profile make marriage within 24 months reasonably probable. Comparable cases—such as markets on other high-profile celebrity couples—have shown that relationship status can shift rapidly, but public engagement announcements typically precede marriages by 12–18 months.

Traders should monitor entertainment news outlets for any engagement announcements, which would likely be reported by outlets including Variety, The Hollywood Reporter, or the couple's own social media. Career scheduling could also prove relevant; Zendaya's film commitments and Holland's Marvel obligations may influence timing. Any public statements from either party regarding marriage intentions would represent a material catalyst affecting the order book's probability assessment.

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 "Will Zendaya and Tom Holland get married 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.

1. Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
2. Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
3. 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.
4. Size your position. If you stake 100 USDC at 67% YES, you'll receive shares that pay $149 if YES resolves true — a 49% gross return. If NO resolves, your shares are worth $0.
5. 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.
6. 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?

$10K in lifetime turnover and $262 of resting liquidity puts this market in the below the median by volume for celebrities 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 4 months — the price has had time to stabilise as new information arrived.

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.

Frequently asked questions

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.
