Market context

Paschal Donohoe's resignation from his Dublin Central seat will trigger a by-election in 2026 to fill the vacancy in Dáil Éireann. The current 1% implied probability on Polymarket's order book reflects substantial uncertainty about which candidate will ultimately prevail, with the market pricing in either a clear frontrunner not yet publicly declared or genuine competitive dynamics that make prediction difficult at this stage.

Dublin Central has historically been a competitive three-way contest between Fianna Fáil, Fine Gael, and Sinn Féin, though Labour and the Greens retain representation in the broader Dublin area. Donohoe himself, a Fine Gael member, held the seat with consistent pluralities in recent general elections. By-elections in Irish constituencies often produce volatile results compared to general election patterns, with local candidate quality and campaign intensity mattering substantially. The 2023 general election saw Fine Gael secure 20.1% nationally whilst Sinn Féin took 20.3%, making either party plausible winners depending on candidate selection and local mobilisation.

Key catalysts for traders include the formal announcement of the by-election date (likely to occur within months of Donohoe's departure), candidate declarations from major parties, and any polling released closer to the election. The settlement window extends to end-2026, providing clarity on whether voting occurs as expected. Local media coverage and party strategy announcements will signal which candidates parties consider competitive, potentially reshaping market pricing as the election approaches.

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.

Settlement window & payout timing

For this market, the resolution date is 31 December 2026. A UMA proposer can submit the outcome from that moment; the two-hour dispute window closes at , and assuming no counter-claim is staked, winning USDC clears to trader balances by approximately .

If a dispute is filed inside the two-hour window, the outcome escalates to UMA token-holder voting, which extends settlement by roughly 48 hours. This particular market has no public resolution feed listed; disputes here are more likely if the underlying outcome is subject to interpretation, in which case the UMA token-vote arbitrates the wording of the original market question.

Withdrawal pace from your PolyGram balance is non-custodial and immediate — once payout clears, funds are yours to send to any Polygon wallet you control. Funds clear directly to your in-app USDC balance on Polygon. Withdrawals are non-custodial: send to any address you control, typical confirmation under 30 seconds, gas paid in USDC if you'd rather not hold MATIC.

Trading mechanics

Minimum order size on PolyGram is $1.00, with no maximum cap aside from available book depth. Orders route into Polymarket's on-chain CLOB on Polygon; the matching engine pairs YES buyers with NO buyers atomically — every executed trade is settled on-chain with no counterparty risk. For "Dublin-Central By-Election Winner", order-book behaviour for this market reflects the underlying volatility of the outcome — patient limit orders typically fill closer to mid than market orders.

The trade ticket includes a slippage box (default 2%, configurable 0.1%-10%) that caps the worst-case entry price. Your maximum loss is your stake — winning YES (or NO) shares pay $1.00 each at resolution. With this market's current book depth ($754K of resting liquidity), a $500 order should fill with single-cent slippage at the displayed mid-price.

PolyGram charges 0% house edge — no spread mark-up, no rake on winnings, no withdrawal fees beyond network gas. The platform earns exclusively from optional features (copy-trade boosts, advanced order types, the yield vault on idle USDC); the trading surface itself is at-cost.

How to trade this market step by step

The mechanics for trading "Dublin-Central By-Election Winner" 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 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% 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?

$3.9M in lifetime turnover and $754K of resting liquidity puts this market in the top 2% by volume for world elections contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.

Last 24 hours alone saw $2.2M in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.

The market has been open for 3 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

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.

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.

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.

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. For "Dublin-Central By-Election Winner", the considerations above apply directly — Trade size should reflect the binary nature of the payoff: even a 70% probability event resolves NO 30% of the time, so any single position can lose 100% of staked capital.

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.
