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 Saturday, October thirty-first.

Sheema: Three stories this morning. In Bulgaria, Iliana Iotova has slid from eighty-eight per cent favourite to sixty-seven in a week, and traders still call her the winner. In Ohio, Vivek Ramaswamy's campaign pulled its attack ad featuring Amy Acton's estranged mother, and yet a quarter of Polymarket's money still bets the contract settles No. And David Lisnard rose to twenty per cent on Polymarket, second only to Marine Le Pen in the French presidential race.

Neil: Iotova lost twenty-one points two days before her contract resolves. That is the story we start with.

Traders keep Iotova favourite in Bulgaria after her odds fall sharply

Sheema: Traders keep Iotova favourite in Bulgaria after her odds fall sharply. Polymarket cut her from eighty-eight per cent on October twenty-fourth to sixty-seven today. Her rival, Andrey Gyurov, sits at thirty-four. The two prices sum to a hundred and one, so traders see a contest between two people.

Neil: The contract resolves Monday, based on credible reporting of the result, including any second round. Does a twenty-one point slide mean traders think Gyurov can take a runoff?

Sheema: Her low was fifty-nine per cent on Friday, October thirtieth, and she has since bounced back eight points. That path reads as volatile trading, not a settled conviction that Gyurov leads. Iotova wins, and sixty-seven per cent underrates her. She held above fifty-nine through her worst day.

Neil: I'd push back on that. A twenty-one point fall in a week is not noise. If traders genuinely thought she held this, why did they sell her to fifty-nine?

Sheema: Because her contract never dropped below Gyurov's. If traders believed he wins the runoff, his price would be above thirty-four. The mechanics settle it. Watch for a strong Gyurov first-round number on Monday. That would reopen the question.

Ramaswamy withdrew the ad. Traders weigh whether that settles it

Neil: Ramaswamy withdrew the ad. Vivek Ramaswamy's campaign ran an attack spot using Amy Acton's estranged mother. Two outlets reported on October thirtieth that the ad is gone. Cleveland.com wrote it will not air in Ohio again. WKBW said Ramaswamy ended it. Polymarket's contract on whether the campaign pulls the ad by eleven fifty-nine tonight trades at seventy-five per cent.

Sheema: Up from twenty-four per cent a week ago. Why is a quarter of the money still on No?

Neil: The contract rule pays Yes only if the campaign, or an authorised representative, publicly announces the ad is stopped. Neither report quotes Ramaswamy or a named aide. Both could rest on ad-tracking data alone. A venue that reads the rule strictly could resolve No, and twenty-five per cent is pricing exactly that.

Sheema: That is the strongest version of the No case, and I think it still loses. WKBW attributes the decision to the campaign. Two newsrooms, same story, same day, describing a deliberate choice, implies at minimum a campaign source. The rule requires a public announcement from the campaign; that is what these reports describe. Twenty-five per cent is too wide for a wording dispute when the reporting already points at the campaign.

Neil: The call is Yes, and seventy-five per cent underrates it. The call is wrong if the ad returns to Ohio air before midnight, or if the contract resolves No tomorrow.

Traders lift Lisnard into second place behind Le Pen

Sheema: Traders lift Lisnard into second place behind Le Pen. David Lisnard's chance of winning France's twenty twenty-seven presidential election rose to twenty per cent on Polymarket this week, up six points from fourteen. Marine Le Pen leads at forty-one. Nobody else listed tops Christine Lagarde's four per cent.

Neil: Is the six-point gain attached to any event, or is it just movement?

Sheema: His low this week was twelve per cent on October twenty-fifth, and most of the gain came in a single day. That fits sporadic buying. A price that dips to twelve and climbs to twenty inside a week is one the market has not settled on.

Neil: So twenty per cent is too high?

Sheema: Twenty per cent is too high. Le Pen at forty-one is the contract this field is priced around. The call is wrong if Lisnard wins when the contract resolves in April twenty twenty-seven. An earlier sign against it: his price still at or above twenty on November thirtieth.
