Trade: Will USD hit ___ Iranian rials by May 31?
Resolution criteria on PolyGram: This market will resolve to “Yes” if the finalized USD exchange rate on Bonbast is equal to or above the specified price for any day between market creation and May 31, 2026. Otherwise, this market will resolve to “No”. This market will resolve according to the daily finalized free-market USD exchange rate as displayed on Bonbast (https://www.bonbast.com/graph/usd), which publishes prices in Iranian toman, where 1 Iranian toman equals 10 Iranian rials (IRR). A daily figure will be considered finalized once the following day’s figure is released.

Market context
The Iranian rial has depreciated significantly against the US dollar over the past decade, driven by sanctions, capital flight, and monetary expansion. This market tests whether the rial will weaken further to a specified level by end-May 2026. The settlement mechanism uses Bonbast's daily free-market rates, which reflect actual trading conditions rather than official pegged rates, making this a genuine measure of market sentiment towards Iranian currency stability.
Historical context shows the rial traded around 24,000 per dollar in 2015 following the nuclear deal, then collapsed to over 300,000 per dollar by 2023 as sanctions tightened and inflation accelerated. The current 48% implied probability on Polymarket's order book reflects genuine uncertainty about whether further depreciation will occur within the specified timeframe. Comparable currency crises in emerging markets suggest that once depreciation accelerates, reversals require substantial policy shifts or external capital inflows—both unlikely given Iran's geopolitical position.
Key catalysts for traders include US sanctions policy announcements, which directly affect capital flows and dollar demand; Iranian monetary policy decisions from the Central Bank of Iran; and broader regional developments affecting oil prices and foreign exchange reserves. Recent reporting indicates Iran's forex reserves remain constrained, limiting intervention capacity. The settlement window extends through May 2026, providing roughly eighteen months for either stabilisation attempts or continued depreciation, making this sensitive to both domestic Iranian policy changes and shifts in US-Iran relations.

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 USD hit ___ Iranian rials by May 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 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.
- 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?
$69K in lifetime turnover and $9K of resting liquidity puts this market in the above the median by volume for exchange rate contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $7K 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 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.
