What happened in the last 24 hours — the stories the money will react to.
Hormuz and the Blockade: Year-End Normal Priced at 23%
The Strait of Hormuz markets moved in the same direction over the past 24 hours, and none of them price a quick fix. “Strait of Hormuz traffic returns to normal by September 30?” sits at 0.4% (−0.2) with five days left, while the year-end version, “Strait of Hormuz traffic returns to normal by December 31?”, rose to 23% (+3). The blockade ladder tells the same story at two horizons: “US announces end of Iranian blockade by September 30, 2026?” is 10% (+4), and the October 31 version 31% (+2). “Will the U.S. invade Iran before 2027?” holds at 13%.
The market treats an off-ramp as possible but unfinished: "US announces end of Iranian blockade by October 31, 2026?" trades at 31%, and "Strait of Hormuz traffic returns to normal by December 31?" at just 23%.
China-Taiwan Invasion Odds Hold Near 4% Into Year-End
The year-end Taiwan contract is one of the deepest geopolitical markets on the board and one of the quietest. “Will China invade Taiwan by end of 2026?” trades at 3.7% (−0.2) over 24 hours on $106K of volume and $681K of liquidity, with 97 days to resolution. That is a small number that has barely moved, which is itself the story: whatever is happening in the Hormuz and Fed markets, this one is not repricing with them.
The market sees China holding fire on Taiwan through year-end: "Will China invade Taiwan by end of 2026?" trades at just 3.7%.
Markets Lean Toward Another Fed Hike in October
The October Fed decision is the busiest economics event on Polymarket, and the money is on a hike. “Will the Fed increase interest rates by 25 bps after the October 2026 meeting?” trades at 67% (−2) over 24 hours, against 33% (+3) for no change; a 50-plus point hike is 1.3%, and both cut legs sit under half a percent. Kalshi’s mirror of the same decision has the 25-point hike at 67% and a hold at 32%. Further out, Kalshi prices a 25-point hike at the January 2027 meeting at 38% (+2), and September CPI above 3.6% year-over-year at 42% (−7). The decision resolves Oct 28, 33 days out.
The market leans toward another rate increase: "Will the Fed increase interest rates by 25 bps after the October 2026 meeting?" trades at 67%, against 33% for no change.
Falcons-Packers: Atlanta Traded at 98% Late Thursday Night
NFL Thursday Night Football: the Packers-Falcons game was the night’s big prediction-market ticket, and the Polymarket order book told the story as it went. Before kickoff the money was split: Tiger200 bought $304K of Packers at 52% on the 4.5-point spread and $364K of the Under at 53% on the 43.5 total, while BrotherObama and raybanman each took six figures of Falcons on the same spread near 49%. By 10:29pm ET the Falcons game market traded at 95%, and by 10:47pm at 98%, with ethanaz alone putting down $346K at that price. The digest carries no final result, so we report the price, not the score.
The late-night price is already in the division markets: Atlanta sits at 22% to win the NFC South on Kalshi, Green Bay’s NFC North share slid to just 7%, and the Polymarket game market traded Atlanta at 98% late Thursday night.
New York and Polymarket Trade Lawsuits Over Gambling Rules
The fight over who regulates U.S. prediction markets escalated. New York sued Polymarket, calling it an unlicensed gambling operation and asking a court to shut it down in the state. Polymarket sued the state attorney general to block the crackdown. The dueling cases follow New York’s earlier moves against Kalshi and others, and could set the pattern for other states. Courts now have to decide who has jurisdiction.
There is no contract on the lawsuit itself, but Polymarket’s own order book did not pause for it: the trader ethanaz bought Falcons at 98% for $224K on Thursday night as the lawsuits made headlines.
Republicans win Maine’s Senate seat — 32% (+5); Democrats 69% (−5.5)
Maine’s U.S. Senate race: the Republican side rose 5 points to 32% in 24 hours, and the Democratic side slipped to 69%. The national map moved with it: a Republican Senate with a Democratic House climbed to 29% (+2), and a Democratic sweep of both chambers eased to 64% (−2). Our read: a five-point single-day move on a Senate seat is large for this stage of the cycle, but at 69% the market still expects the Democratic side to carry Maine.
View market ↗Falcons win the NFC South — 22% (+14); Packers win the NFC North 7% (−11)
NFL division races, the morning after Thursday night’s Falcons-Packers game: the Polymarket game market had Atlanta at 98% by 10:47pm ET, and the season-long prices repriced with it. Atlanta’s odds to win the NFC South rose 14 points to 22%, still behind New Orleans (44%) in the division. Green Bay’s odds to win the NFC North fell 11 to 7% while Minnesota (38%, +5) and Detroit (37%, +4) gained. One September night reshuffled two division races.
View market ↗Korea Open: Kimberly Birrell over Katie Volynets — 70% (+38); Volynets 28% (−39)
Women’s tennis, the Korea Open, a regular tour stop rather than a major: the match between Kimberly Birrell and Katie Volynets swapped favorites before either had hit a ball. Birrell went from 32% to 70%, and Volynets fell from 67% to 28%. Polymarket has Volynets at 31%, so the two venues roughly agree. It is here because of the money: it is Kalshi’s most-traded market of the day. No public catalyst explains a swing this size before a first serve. The match starts at 10pm ET tonight.
View market ↗Democrats sweep both chambers? The market says 64%.
Five weeks out, the odds leave little room for a Republican House.
Control of Congress after the November midterms: the market prices a Democratic Senate and House at 64% (−2) over 24 hours, and a Republican Senate with a Democratic House at 29% (+2). Add them up and 93% of the odds go to a Democratic House; the remaining 7% is every scenario in which Republicans keep it. The market resolves Nov 2, 38 days out.
Read the two legs together and the House is nearly a settled question in this market: 93% Democratic across the two liquid scenarios. The Senate is where the money disagrees. The sweep (64%) and the split (29%) moved two points in opposite directions in 24 hours, which is exactly what you would expect if traders were repricing a single Senate seat rather than the national mood.
That seat may be Maine, where the Republican price rose in the past 24 hours to 32% (+5) and the Democratic price slipped to 69% (−5.5); it is in Movers. The Kalshi 2028 presidential market shows how far out the crowd is already looking, with Jon Ossoff at 12% and Mark Kelly at 3%, but none of that settles who holds the Senate in January.
Our read: the House looks close to settled in the market’s own arithmetic, so the sweep price is really a Senate price, and a Senate price comes down to a handful of states rather than the national mood. Nothing in the digest says 64% is too high or too low for that. We revisit if the sweep and split prices pull further apart, or if a specific state race like Maine moves the arithmetic again.
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, Friday ACC game: the closest big matchup on the board. Clemson is 52% (+2) in 24 hours, California 48%. 174K contracts traded in 24 hours, more than any competitive game on today’s board.
International soccer, afternoon kickoff: France is 74% to win (+5) in 24 hours, with $228K traded in 24 hours. A draw settles NO, so the other 26% covers both a Türkiye win and a tie.
MLB: Cubs 52%, Red Sox 48% (−2) in 24 hours. A genuine coin flip, and the second-busiest baseball game today at 53K contracts traded.
The biggest individual trades of the last 24 hours — who put money down, how much, and how it went.
Money went both ways on the same Norway match. The account ripley86alien bought about $516K of NO at 39–40% on Thursday afternoon, hours before YES traded at 99.9%.
Mitch Landrieu says he’s ‘seriously’ weighing 2028. The market says 0.1%.
$567K changed hands in a day on a former New Orleans mayor with no campaign, no fundraising, and a decision date after the midterms.
The 2028 Democratic presidential nomination: two days after telling Politico he is “seriously” thinking about running, former New Orleans Mayor Mitch Landrieu is priced at 0.1% to win it — (+0.1) in 24 hours, a move from nothing to almost nothing. The Washington Examiner reports he plans to decide after the midterms, possibly late this year, and has announced no campaign organization or fundraising. Still, $567K traded on the contract in a day. That is a lot of trading for a one-in-a-thousand outcome, and activity is not evidence that anyone knows something.
What has to happen: the contract pays only on the nomination itself — not an exploratory committee, not a poll bump, not a convention speech. Landrieu would need to declare, raise money, and win a primary before this settles in November 2028, 773 days out. The nearest yardstick: Polymarket gives Democrat James Talarico 0.7% to win the entire 2028 election, seven times Landrieu’s price for the smaller prize of a nomination. Our read: a price this low is a placeholder, not a forecast — entertainment until someone files paperwork. ↗
