Eventcmtla1gwx00kmmv01zv1jfl0a
Closes in

This market will resolve according to the party that wins control of the United States Senate in the 2026 United States midterm election. A party wins control of the United States Senate if it wins a majority of the chamber’s voting seats. If no party wins a majority of voting seats, the party that wins control of the chamber is the party that wins half of the voting seats and holds the Vice Presidency. If the outcome remains ambiguous after applying the above criteria, the chamber will be deemed controlled by the party with which the first selected President Pro Tempore of the Congress that convenes after the specified election is affiliated. The following rules govern the counting of seats for determining which party wins control of the chamber. All regular and special Senate elections that determine representation in the upcoming 120th Congress and are scheduled to take place in November 2026 as of October 31, 2026 are included. Runoffs for qualifying elections will determine attribution of the relevant seat, even if they take place after November 2026. Vacant seats for which no election or special election to fill the seat is scheduled to take place in November 2026 as of October 31, 2026 will be treated as held by the party affiliation of the most recent member to hold that seat. For seats contested in the specified election, seats are attributed to the party under which the member was elected. If a member-elect changes party affiliation, or vacates their seat, between election day and the formal organization of Congress, the seat is attributed to the party under which the member was elected. For seats not contested in the specified election, seats are attributed to the party that holds the seat as of the date of the election. If a current sitting member of the U.S. Senate who is not up for election changes party affiliation or vacates their seat after the date of the election, the seat is attributed to the party under which the member was affiliated at the time of the election. Senate members elected as independents who formally caucus with, or, for newly elected members, who announce their intent to caucus with, a party are included in that party’s count. If the caucus decisions of members of the Senate elected as independents cannot be determined on the date of the election, this market may remain open until the earlier of (i) an announcement from the relevant members of their intents to caucus, or (ii) January 4th, 11:59 PM ET of the following calendar year. If no such announcement is made by January 4th, 11:59 PM ET of the following calendar year, the member will not count towards the seat count of any party. The resolution sources for this market will be official information from relevant state electoral authorities, the United States Congress, and a consensus of credible reporting.

No party, let alone incumbant, has reversed a +9 (or, holistically, +13) generic ballot poll in US history, precedent if anything argues that it will only exacerbate. Odds are closer to 80-85% and the house is essentially 99% bar a deeply exogenous event. America's anti-Trump stance on Iran indicates that the most common cause for such a rare reversal is also acting against him.

The only confused people are the insecure closeted gay men in the Republican Party. The only one braking the law is the current administration and its idiotic voters storming the capitol. Not a single democratic voter that I know supports unregulated borders and neither do any of the politicians (Biden deported over 270k in his last year in office btw). The most American thing is to support peoples freedom which is currently being suppressed. Not a single Democratic politician is a communist and only a small handful are democratic socialists that are not even remotely communist. The only voters that are radical are those threatening other Americans with violence. Never vote agin.🤡

That's all you Maga morons worry about. The color of people's skin and what someone's private parts look like. Maga is done in November. I wonder if you'll still protect pedophiles then?

This comment might make sense to someone who actually believes brown people are the true source of your economic issues…. Billionaires paid a lot of money to get you to believe that nonsense. They’re very satisfied that their investment is going so well.

hdtomo Sep 2

Biden can handle a major global financial event without recession and he's got dementia, but Trump can lose a war, double the deficit while somehow hurting the economy, reduce government efficiency, perform hundreds of insider trades, on top of being a total dick and eroding democracy and it's just "b-b-but Trump bad!"

my man has zero dollars riding on this, but for whatever reason still seems to be invested into this bet...

Just a reminder Democrats have no policies and will 100% return America to the Biden era inflation / open borders / increased crime all while telling you that you're supposed to be happy you're being replaced by millions of foreigners. Clowns all of you. "B-b-but Trump bad, Iran war... 🥺" You guys look ret4rded. Trump already proved he can get gas below $3 in 40 states and once the war ceases it'll go back down but you guys would rather we flood our borders again and grant mass amnesty to people who don't follow our entry laws.

Are you mentally challenged? Democrats are the worst thing to ever happen to America. You're all gender confused, anti-law, anti-border, anti-america, communist, and radical. Never vote again 🤡 you have no reason to convince anyone to vote Democrat because Democrats couldn't even keep the border secure under Biden. You're a joke

Nate silver model prediction showing dems with a 57% of winning moved the markets since he is given credit for being a knowledgeable stats based modeler.

That is the beauty of markets I suppose. Whales will only be whales if they continue to make money. If, in this specific case they happen to be taking the wrong side of the bet....

hdtomo Aug 22

This fuckery about keeping it close for the Republicans because some whales can't wrap their heads around the Democrats winning needs to stop. It happened to Texas for 8 months too.

because

dPredictor Aug 17

look at this headline "Federal Court Blocks U.S. Postal Service from Implementing Executive Order Restricting Mail Voting" Trump's Attempt to block mail-in votes failed and the marked moved acordingly (Republicans are more likely to be old retired folks who don't work for a living and can go vote in person)

Nate Silver forecast came out

snoopy2322 Aug 14

At around 8am a federal judge issued a national wide rulling on a suit brought by the women's league in Massachusetts against parts of trumps election integrity order, specifically a part of the order that directs the postmaster to withhold mail in ballots from states that dont turn over voter rolls. The trump administration asked the Supreme Court to take up the case and markets reacted accordingly.

Nate Silver is a clown who is not very good at his job, look at his coverage of the last elections.

Betting on Republicans, so if I lose, I'm still happy

Iran is allegedly doing cyberattack in US water facilities. Trump denies that they are running out of munitions but more and more US military are telling him this - Hormuz Letter, X.
