US announces end of Iranian blockade by November 30, 2026 priced at 33.5% on Polymarket, up 7 points, on $275K traded

Blockade-end contract moves higher

Polymarket’s contract on whether the US announces an end to the Iranian blockade by November 30, 2026 was priced at 33.5%, up 7 probability points, with $275K traded, in the supplied October 20, 2026 update published at 11:54 AM ET.

According to PredictionBubbles, the contract appeared among upward political moves on its movers board. The listing places it in a political/geopolitics category; it does not establish that a blockade-ending announcement has occurred.

What the board measures

PredictionBubbles ranks changes over 24 hours using probability points rather than relative percentage changes. Its supplied snapshot drew venue prices on 20 Oct 2026, 15:42 UTC, and the board refreshes every 15 minutes using prices from Polymarket and Kalshi.

The ranking covered 2,007 markets running longer than 14 days. Only open contracts with a valid 24-hour comparison qualify, according to PredictionBubbles. Volume and liquidity provide context but do not determine a market’s position in the movement ranking.

The supplied material does not identify a news event or official announcement behind the blockade contract’s rise. It separately names the question of whether the US–Iran ceasefire continues through October 31 as a biggest mover. That is a different contract from the November 30 blockade-end question and should not be treated as interchangeable.

What it means for prediction markets

• A higher price, not confirmation: The 7-point increase records a change in traders’ assessment. At 33.5%, the announcement outcome remains priced below an even chance.
• The precise question matters: This contract concerns a US announcement by November 30, 2026, rather than the separate question of ceasefire continuation through October 31.
• Turnover is only part of the context: The reported $275K traded does not, by itself, establish order-book depth or explain the move. The supplied material provides neither a verified catalyst nor detailed settlement rules.
