Every morning this site records the price of every contract it tracks. Read across seven days, those readings show where traders changed their minds and where they did not. This is the first weekly review of that archive, covering October 17 to October 24, 2026. Prices are YES prices in cents, and a YES price reads as the market's probability.
The Ballon d'Or market gave up on Yamal
The biggest swing of the week came from football. On October 17, "Will Lamine Yamal win the 2026 Ballon d'Or?" traded at 28 cents on Polymarket. This morning it is 8 cents, on $5.5 million of volume. Harry Kane went the other way, from 65 cents to 70 cents with $7.1 million traded, the most money on any contract in the race. Kylian Mbappé rose from 4 cents to 15 cents, and Lionel Messi slipped from 3 cents to 2 cents.
Read as probabilities, the market now gives Kane about a 70 percent chance, Mbappé about 15, and Yamal under 10. Those three add up to roughly 93 cents, which leaves only a few cents for everyone else on the ballot. The Polymarket contracts close on October 27.
The same race trades on Kalshi, and the two exchanges do not quite agree. Kalshi has Mbappé at 18 to 20 cents against 15 cents on Polymarket, a gap of about four points on the same question with three days left. Kane is within a point on both exchanges, at 70 to 71 cents.
The October Fed meeting is priced as a non-event
The Fed decides on October 29, and the market has stopped arguing about it. "Will there be no change in Fed interest rates after the October 2026 meeting?" climbed from 87 cents on October 17 to 95 cents this morning, on $18.4 million traded. The contract for a 25 basis point increase fell from 14 cents to 6 cents, and the contracts for a cut of any size sit at a penny.
A 95-cent price says traders put the chance of a hold at about 19 in 20. That is not certainty. A 5 percent event happens one meeting in twenty. But it tells you the week's news moved the remaining doubt out of the hike column rather than into it. The longer-dated contract asking whether no Fed rate cuts happen at all in 2026 is at 97 cents.
Limitless lists the same October decision in much thinner markets, and its prices track Polymarket almost exactly: 95 cents for no change and 6 cents for a hike.
The Anthropic IPO contracts went opposite ways
Two contracts about the same company moved in opposite directions, and the pair is worth reading together. "Will Anthropic IPO by December 31, 2026?" rose from 71 cents to 79 cents. "Will Anthropic have the highest IPO market cap of 2026?" fell from 36 cents to 25 cents. Traders grew more confident that the listing happens this year and less confident that it would be the year's largest.
The rest of the IPO board puts that in context. The SpaceX contract for the highest 2026 IPO market cap held at 64 cents all week, so the repricing was about Anthropic alone, not a swap between the two. "OpenAI IPO closing market cap above $1T?" eased from 72 cents to 65 cents. That contract does not close until the start of 2028, so it is less a forecast of a date than a running vote on valuation.
The quiet money
The most traded contract on the site is still "Will the U.S. invade Iran before 2027?", at $75.1 million. It moved from 15.5 cents to 18.5 cents this week, a real move on a question with 69 days left.
Below it sit the penny contracts that dominate the volume table: Jesus Christ returning before 2027 ($66.7 million, 1 cent), LeBron James winning the 2028 presidential election ($54.9 million, 1 cent), and a run of 2028 nomination contracts at a cent each. Heavy volume on a 1-cent contract is usually traders earning a small, near-certain return on the NO side, not a signal about the event. The Iran contract is the one in that top group whose price can still move on news.
Closing this coming week
Three contracts with real money behind them settle in the next seven days:
- October 27: the Ballon d'Or contracts on Polymarket. Kane 70 cents, Mbappé 15, Yamal 8.
- October 28: "Will Benjamin Netanyahu be the next Prime Minister of Israel?" at 28 cents on $10.7 million, down from 30 cents a week ago.
- October 29: the October Fed decision, with no change at 95 cents.
When they settle, the archive will show which prices were right, and next week's review starts from there.
