Kalshi's October hike contract ended near 13 cents after a 55-cent peak. Two September CPI contracts paid on a single tenth. Polymarket's 5.4% yield rung fell to about 36%.
This was the hottest inflation week in years.
Core consumer prices rose 0.3% for a second month. Producer prices jumped 1.3%, the most since 2022.
The contracts tied to the Fed and to yields still ended the week lower.
Kalshi's October hike contract tripled on the CPI report, then gave most of it back. Its biggest drop came after the Fed chair declined to say anything. Polymarket's 10-year rungs fell as Treasury closes slid to 5.10%.
The contracts that settled on a printed number paid on that number. The ones tied to decisions moved on words and calendars.
Data moved prices for minutes.
Words and rules set where they ended.
Here are the six that explain the week.

The Hike Moved. It Did Not Vanish.
CONTRACT: Kalshi's October rate-hike contract, alongside its December counterpart.
START-OF-WEEK PRICE: October near 16 cents. December near 70 cents.
END-OF-WEEK PRICE: October near 13 cents Friday afternoon. December near 77 cents.
CATALYST: The October contract jumped from 18 cents to 55 cents within about 36 minutes of Wednesday's CPI report. The peak printed on about 600 contracts. Thursday's producer-price jump briefly lifted it to 37 cents. Then Fed Chair Kevin Warsh declined to signal the Oct. 27-28 meeting. The contract fell from about 28 cents to near 13 overnight.
RESOLUTION CONDITION: October pays only on a quarter-point hike at the Oct. 28 decision. December pays only on a quarter-point hike at the December meeting, not on a hike by December.
WHAT THE MARKET ACTUALLY SAID: Hot data raised the October odds for minutes. A chair's silence cut them in half overnight, and no Fed official speaks publicly before the meeting. December gained as October lost. Traders moved the date of the next hike, not its direction. A 13-cent price still implies about a one-in-eight chance of an October move.
A Tenth Paid. The Wording Decided Which Line.
CONTRACT: Kalshi's September CPI contract and its core counterpart.
START-OF-WEEK PRICE: Headline CPI above 0.5% near 59 cents Monday. Core CPI above 0.2% near 36 cents.
END-OF-WEEK PRICE: Both paid $1 on Wednesday.
CATALYST: September consumer prices beat forecasts. Headline prices rose 0.6% on the month, and gasoline supplied more than half of the gain. Core prices rose 0.3%, a tenth above forecasts.
RESOLUTION CONDITION: Each line settles on the single-decimal value the Bureau of Labor Statistics reports. "Above 0.5%" means 0.6% or higher. So the same 0.6% print paid the 0.5% line and missed the line above 0.6%, which last traded near 21 cents.
WHAT THE MARKET ACTUALLY SAID: The headline line traded near 68 cents before the release, about a two-in-three chance. The core line sat near one in three most of the week. So the bigger surprise came in core, the measure the Fed watches when energy drives the headline. Energy is already in freight bills. [About $285 million of J.B. Hunt (JBHT)'s revenue gain came from fuel surcharges](https://www.financialmarkets.com/article/jb-hunt-added-624-million-of-quarterly-revenue-much-of-it-fuel-surcharges-operat), while operating income rose 2%. Neither price was a forecast. Each was a probability, and the printed tenth settled it.
You’re Being LIED To About The Iran War
Forget EVERYTHING you’ve heard about the Iran war.
Especially the reasons why we’re bombing the country.
Hot Prints, Lower Rungs.
CONTRACT: Polymarket's 10-year yield ladder
START-OF-WEEK PRICE: The 5.4% rung near 62%. The 5.5% rung near 40%.
END-OF-WEEK PRICE: The 5.4% rung near 36% Friday afternoon. The 5.5% rung near 27%.
CATALYST: The 10-year touched about 5.33% after the CPI report, then closed Wednesday at 5.19%. It fell to 5.10% Thursday, a three-week low, after the producer-price jump. Retail sales outside autos and gasoline rose only 0.2%.
RESOLUTION CONDITION: Each rung pays if the Treasury's daily par yield table shows the 10-year at or above the line on any day before 2027. Intraday trades do not count.
WHAT THE MARKET ACTUALLY SAID: The 5.4% rung briefly rose near 65% around Wednesday's intraday spike. It fell once the table close came in far lower. Bond buyers absorbed two hot reports, and no single cause explains it. Soft spending is one reading that fits. Banks feel the swing too. [PNC (PNC)'s unrealized losses grew by $2.4 billion last quarter](https://www.financialmarkets.com/article/us-bancorp-and-bny-rose-on-their-results-pncs-unrealized-losses-grew-by-24-billi) as long yields climbed. The ladder now treats a 5.4% close as about a one-in-three chance, down from better than even.
Twelve Attacks, Fewer Odds of an End.
CONTRACT: Polymarket's contract on a U.S. announcement ending the Iran blockade
START-OF-WEEK PRICE: Oct. 31 near 14.5%. Dec. 31 near 44.5%.
END-OF-WEEK PRICE: Oct. 31 near 4.5%. Dec. 31 near 34%. The Oct. 15 contract expired No.
CATALYST: Singapore said the container ship GFS Pride sank near Hormuz after a projectile strike. Reported ship attacks near Hormuz reached 12 from Oct. 5 to 11, the most in any week since the war began. Kpler put flows at about 11.6 million barrels a day, a third below its baseline.
RESOLUTION CONDITION: The contract pays only on an official U.S. announcement ending or suspending the naval blockade of Iran. Ship traffic, talks and pledges do not count.
WHAT THE MARKET ACTUALLY SAID: Part of the October drop is the calendar, since fewer days remain for an announcement. The year-end line has more time left, and it still fell about 10 points. That suggests traders see less room for a deal in 2026, not just this month. Oil producers read it the same way. ExxonMobil (XOM), Chevron (CVX) and ConocoPhillips (COP) touched all-time highs on Wednesday.
Porter Stansberry's Critical New Warning:
Trump Is Replacing The U.S. Dollar
"The last time America reset its money, it created 1,300 millionaires every day. This could be bigger."
The War Got Closer. The U.S.-Strike Bet Got Smaller.
CONTRACT: Polymarket's contract that pays if the U.S. does not strike Yemen by Oct. 31
START-OF-WEEK PRICE: Near 79.5 cents.
END-OF-WEEK PRICE: Near 91.5 cents.
CATALYST: Houthi attacks reached Saudi Arabia's oil company. Saudi Arabia said a strike on an Aramco office in Dhahran caused a limited fire. Reuters, citing three people with direct knowledge, reported extensive damage. President Trump wrote that he will "be there after the Elections."
RESOLUTION CONDITION: The bet on U.S. restraint loses only if American forces strike Yemeni soil by air or with a surface-to-surface missile. Saudi-led raids and Houthi missiles do not count. The contract ends Oct. 31, before Election Day on Nov. 3.
WHAT THE MARKET ACTUALLY SAID: Regional escalation lifted the price on U.S. restraint. The rule explains the gap, and the president's post pointed past the settlement date. Implied odds of a U.S. strike fell from about one in five to under one in ten. Under $100,000 had traded on it by Tuesday, so small orders still move it.
The Polls Tightened. The Price Followed Late.
CONTRACT: Polymarket's contract on a Flávio Bolsonaro win in Brazil
START-OF-WEEK PRICE: Near 86 cents.
END-OF-WEEK PRICE: Near 77 cents.
CATALYST: A string of polls put the Oct. 25 runoff inside the margin of error. Datafolha showed Flávio ahead 51-49 in valid votes, narrower than its 52-48 a week earlier.
RESOLUTION CONDITION: The contract pays on who wins the election, not on poll margins.
WHAT THE MARKET ACTUALLY SAID: The price drifted toward the polls, but not on their timing. Nearly half of Thursday's drop came in an hour with no new poll. It then rose about 2.6 cents around Datafolha's release, even as the race narrowed. A 77-cent price still implies about 3-to-1 odds for a candidate polling a point or two ahead. That gap is a claim traders are making about the polls, not evidence of the result.
He predicted the 2008 financial crisis…
He predicted Trump’s election in 2016….
He even predicted the rise of COVID-19 writing:
“The chance we don’t have something on the scale of a national pandemic in the next few years is near zero”
That was three months before the first reported case.
If he’s right again, God Bless America…
Because this crisis will be tectonic in scale…and it's going to begin with the bubble popping in AI.
The contracts that read a printed value paid on it. The contracts tied to decisions moved on words, dates and deadlines.
October lost its hike to a chair's silence. Yields fell through two hot reports. A regional war widened, and the bet on U.S. restraint firmed.
Data sets the spike.
The rule and the calendar set the price.
