Opening

Sheema: Good morning and welcome to The Rumpus Daily. I'm Sheema Sharti.

Neil: And I'm Neil Matthews. Every weekday we bring you the signals from the world's prediction markets. Today is Thursday, October twenty-ninth.

Sheema: Three stories this morning. Israel's election produced no majority, and two prediction markets are sixteen points apart on whether Netanyahu survives it. Traders on Polymarket raised the odds that Washington officially ends its naval blockade of Iran by the thirtieth of November. And on Kalshi, a gas price contract swung thirty-five points in two days without settling the question.

Neil: Nearly four million dollars traded on the Netanyahu contract in the last twenty-four hours, and the two venues are telling different stories.

Sheema: We start with Israel.

Netanyahu holds near even odds as Israel's election leaves no majority

Sheema: Netanyahu holds near even odds as Israel's election leaves no majority. Polymarket prices him at forty-six per cent to become the next prime minister. Kalshi prices the same question at twenty-nine per cent, a sixteen-point gap between two separate markets and two separate crowds of traders.

Neil: The Times says he lost support but still has several ways to stay in power. If one of those paths holds, forty-six per cent is fair.

Sheema: A path is not a sworn-in government. Neither Netanyahu's right-wing bloc nor the opposition alliance led by Gadi Eisenkot won a majority in the hundred-and-twenty-seat Knesset. The Times calls the result ambiguous. So what explains the sixteen-point gap between the two markets?

Neil: Kalshi lets traders bet on deadlock directly, and that option, no one becoming prime minister, leads its event at fifty-four per cent. Polymarket lists candidates separately. The deadlock case has no dedicated home there, so the probability scatters across the named candidates.

Sheema: And the contract's listed resolution date, the twenty-eighth of October, has passed. Is the price still live?

Neil: The rule pays only on formal swearing-in, and he has not been sworn in. So both prices are forecasts of a deal through the end of 2026. Polymarket's forty-six per cent overstates him.

Sheema: In Israel, parties formally recommend to the president who gets the first chance to form a government. When the Arab parties make that recommendation, it may move this price. Watch for that signal.

Traders lift odds that Washington ends its Iran blockade by November

Neil: Iran blockade now. Traders on Polymarket have been lifting the odds that Washington officially ends or suspends its naval blockade of Iran by the thirtieth of November. The contract moved from twenty-three per cent on the twenty-second of October to twenty-eight per cent today.

Sheema: The rule pays on a suspension as well as a full lifting. That bar is lower than it sounds. Does the five-point climb change your read?

Neil: The other deadlines in the same event argue against it. The contract for an end by Saturday the thirty-first of October trades at three per cent. The contract for an end by the thirty-first of December trades at forty per cent. Traders expect any end to the blockade to come late, and give better than even odds that none comes this year.

Sheema: Our call is that Washington does not announce an end or suspension by the thirtieth of November, and twenty-eight per cent runs too high. The Trump administration reinstated the blockade only on the thirteenth of July. An official announcement ending, lifting or suspending the blockade by 11:59 Eastern on the thirtieth proves that wrong.

Traders trim odds of US gas averaging above $4.18

Neil: Gas prices to close. Traders on Kalshi have swung a contract between eighty-two per cent and forty-seven per cent this week on whether AAA's national average price for regular gasoline clears four dollars and eighteen cents on the second of November. It now sits at sixty-four per cent.

Sheema: Why the swings? What makes this contract move so sharply on small data?

Neil: The neighbouring price levels in the same event explain it. The contract for a reading above four dollars and sixteen cents trades at ninety-six per cent. The contract for above four dollars and twenty cents sits at thirty-nine per cent. Traders think the average lands within a cent or two of that four-eighteen line, so each new AAA reading can shift this contract fifteen to twenty points.

Sheema: The week's direction is still downward. It opened at seventy-three per cent, touched eighty-two, fell to forty-seven, and now sits at sixty-four. Our call is that AAA comes in at or below four dollars and eighteen cents on Monday, and sixty-four per cent overrates a finish above the line. An AAA reading above four-eighteen on the second proves that wrong.

Close

Sheema: Neil, thanks very much.

Neil: Thanks, Sheema.

Sheema: That's The Rumpus Daily for Thursday, October twenty-ninth. We'll see you tomorrow.
