Strait of Hormuz traffic returns to normal by 2026?

Platform comparison

Market context

The Strait of Hormuz is still being judged against a hard operational threshold: IMF Portwatch must show a 7-day moving average of at least 60 ship calls for the market to settle Yes. That is a fairly demanding bar because the underlying flow has only recently been recovering from disruption, and the current crowd-implied probability of 13% suggests traders think a sustained return to normal is still unlikely before the 31 August 2026 settlement window closes.

Recent prediction-market pricing has been much higher than the current 13% on the contract itself, which points to a notable gap between longer-dated optimism and near-term settlement risk. CNBC reported in July that Kalshi traders had put roughly 38% on traffic returning to normal by year-end and 47% by July 2027, while earlier summer coverage showed the market swinging sharply from a majority view that normalisation could arrive by late summer to a more cautious stance after renewed setbacks.[7][8] Analyst commentary has also been split: Kpler and other shipping specialists have argued that even if voyages resume, backlog clearance, route caution and operational delays could keep the 7-day average below the 60-call trigger for weeks or months.[2][9][17]

For traders, the key catalysts are not just diplomacy but the pace of actual sailings, insurer confidence, and any Portwatch updates showing the moving average climbing through the 40s and 50s towards the threshold. The main event risk is an official or informal reopening signal that quickly lifts daily transit calls, but the market will only resolve on published IMF Portwatch data, so headline claims matter less than whether commercial vessels physically return in volume.[1][4][18] Compared with broader commentary that the strait could normalise later in 2026 or even 2027, this contract is pricing in that the required level may simply not be reached in time.[1][2][6]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
