What happened in the last 24 hours — the stories the money will react to.
Trump Announces U.S.–Denmark–Greenland Security Agreement
U.S. foreign policy: President Donald Trump announced a security agreement with Denmark and Greenland on Friday. Per The New York Times, the pact expands the U.S. military presence in Greenland and bars adversary bases, with no transfer of territory. The formal signing is scheduled for the UN General Assembly next week. What comes next is whether the signature actually lands on the calendar it was given.
The market on a Trump–Greenland deal being signed by December 31 jumped to 96% (+80.6) on $134K of volume. Note the thin $52K of liquidity behind that price.
Russia Votes for a New Duma Through Sunday
Russian politics: voting in Russia’s State Duma elections began Friday and runs through September 20. United Russia, the ruling party, goes in as the heavy favorite to retain the largest share of seats; it won 324 last time. The result is the one thing on the board this weekend that Polymarket traders are spending real money on.
United Russia to win the most seats trades at 75% (−2) on $2.6M in 24 hours, the biggest market on Polymarket by volume. New People sits at 24% (+4); every other party is priced under 2%.
Missouri AG Sends Cease-and-Desist Letters to Six Prediction-Market Operators
Prediction-market regulation: Missouri’s attorney general issued cease-and-desist letters to six operators, including Polymarket and Kalshi, telling them to stop offering sports bets in the state. The state-by-state fight is widening: Underdog is suing Connecticut over that state’s own crackdown. Sports contracts are where the volume is, which is exactly why they are where the fight is.
No market settles on the letters. The sports contracts in question are the busiest thing on the board today: LSU–Ole Miss alone has 3.0M contracts traded on Kalshi, with LSU at 59%.
Yahoo Finance Ends Its Polymarket Partnership
Prediction-market distribution: Yahoo Finance and Polymarket have ended their partnership, Bloomberg reports, after Yahoo closed its prediction-markets hub. On the same day, Kalshi announced a partnership with a Native American tribe on a tribal-owned prediction-market app. One venue loses a mainstream front door; the other opens a new one.
Polymarket’s tape looks unbothered: $2.6M traded on the Russian Duma market alone in 24 hours, and $1.2M each on Sevilla–Barcelona and a League of Legends playoff game.
Barcelona Priced Near 80% at Sevilla
La Liga, Spain’s top soccer league: Barcelona visits Sevilla on Saturday in the day’s most heavily traded soccer market. Polymarket has moved $1.2M through the Barcelona-to-win contract in 24 hours, and the price has drifted five points lower over that window. Sevilla is priced as a long shot on Kalshi, which leaves a little over a tenth of the outcome to the draw.
Barcelona is priced at 79% on Kalshi and 78% (−5) on Polymarket’s mirror of the same match. Sevilla gets just 9% on Kalshi.
Trump–Greenland deal signed by Dec. 31 — 96% (+80.6)
A U.S.–Denmark–Greenland security agreement: Trump announced it yesterday, and the market on whether a Greenland deal gets signed by December 31 jumped from roughly 15% to 96% in a day. The New York Times reports the pact expands the U.S. military presence in Greenland and bars adversary bases, with no transfer of territory, and that the formal signing is set for the UN General Assembly next week. Our read: the market is counting a security pact as “the deal,” and the 4% left over is the distance between an announcement and a signature.
View market ↗Russian Duma election: United Russia wins most seats — 75% (−2); New People 24% (+4)
Russia’s parliamentary election: voting for the State Duma began Friday and runs through September 20, with United Russia, the ruling party, expected to keep the largest bloc. Its contract slipped two points to 75% while New People, a smaller party, climbed four to 24%. United Russia took 324 seats in the previous Duma. A one-in-four chance that another party finishes first is not how Russian elections go. Read the contract’s fine print on how “most seats” is counted before trusting either price.
View market ↗Anthropic IPO by Oct. 31 — 4.8% (−49.7)
Anthropic, the AI company, and its stock-market debut: Dow Jones reports the company pushed its planned IPO from October to November so it can include third-quarter financials. The contract on an IPO by October 31 fell from roughly 55% to 4.8% in a day. Our read: Anthropic is no less likely to go public, just less likely to do it before this deadline. A deadline bet pays nothing for being right a month late.
View market ↗Heisman Trophy: Darian Mensah — 28% (+10); Malachi Toney 5% (−7)
The Heisman Trophy, college football’s top individual award: Darian Mensah’s contract rose 10 points to 28% over the past day, and Malachi Toney’s fell seven to 5%. No public catalyst explains either move. There are 1.19 million contracts open on Mensah alone, so this is a widely held view rather than a stray one. A full Saturday of games will reprice this list before tonight.
Can the Clarity Act become law this year? The market says 8%.
A crypto bill priced in single digits, and 104 days on the clock.
The Clarity Act, the crypto market-structure bill, is priced at 8.4% (+0.4) to become law in 2026, on $235K traded in 24 hours. The market resolves Jan. 1, 104 days out, or sooner if the president signs.
This is a bill to set the rules for U.S. crypto markets, and the market treats passage this year as a long shot. The price has barely moved over the past day, and $736K of liquidity sits behind it, so this is not a thin quote that a few dollars could push around. Single digits with real depth behind them is a market that has made up its mind.
The steelman for YES is simply that 8.4% is not zero: the contract stays live until Jan. 1, and a year-end legislative window can move fast when it moves at all. But nothing in the tape, a +0.4 drift on $235K, suggests anyone is positioning for that.
Our read: 8.4% is a fair price for a bill that still needs to clear Congress and get a presidential signature in 104 days with no visible momentum. A scheduled vote would make YES worth a look. Without one, there is nothing to bet against.
Today’s markets deciding — a side, a price, a time. Trade idea means a documented edge; price to watch means a stated price would change our mind; watch means worth reading, no edge claimed. All markets open at send.
College football’s biggest market of the day by far: 3.0M contracts traded, 720K in the last 24 hours. LSU sits at 59% and Ole Miss at 42%, a near coin flip leaning LSU in the SEC game everyone is watching.
Premier League: Arsenal is 57% to win at Brighton on both venues (Kalshi also shows 57%), and Brighton is 19% on Kalshi, which leaves about a quarter of the outcome to a draw. The over on 2.5 total goals sits at 54% (−3) over 24 hours.
The biggest individual trades of the last 24 hours — who put money down, how much, and how it went.
Money went both ways on Chelsea: halvanicus bought YES at 36–38% in three purchases totaling about $801K, within minutes of totoro3miyazaki’s NO buys.
Iran leadership change by September 30 is priced at 1.1%. $355K traded on it in a day.
Eleven days, one very specific contract, and a lot of trading on something the market says almost certainly won’t happen.
Iranian politics: the market asking whether Iran’s leadership changes by September 30 sits at 1.1% (−0.4) over 24 hours. Eleven days is not much time to change who runs a country, and the price agrees. Even so, $355K traded on it in a day against $239K of displayed liquidity, so more money changed hands than the market showed available at any one moment.
For YES to pay, something the contract counts as a leadership change has to happen by 11:59pm ET on September 30. The contract’s terms, not the headlines, decide what qualifies, so read them before touching either side. There is no reliable base rate for an event like this. The nearest comparison is a separate market that prices a U.S. invasion of Iran before 2027 at 15%; that is a longer window and a different event, and it says how nervous the market is about the region without saying who sits in Tehran in October. That is a lot of trading for a 1.1% outcome. Volume does not mean anyone knows something is coming, and a NO share bought near 99% loses its full price if the 1.1% arrives. Our read: the price is the information here; the volume is the entertainment. ↗
