A 50,000-contract buy order hit at 34 cents as traders reacted to the biggest producer-price increase since 2022. By 9:20 a.m. the contract was back at 28 cents and stayed there through early afternoon, a few cents above where it began the morning.
For about 20 minutes on Thursday morning, traders on Kalshi priced a meaningfully higher chance that the Federal Reserve raises rates this month. Then they stopped.
Kalshi's contract on a 25-basis-point increase at the Oct. 27-28 meeting traded at 26 cents shortly after 5 a.m. Eastern and fell to 23 cents by 6:05 a.m., its low for the day. Through 8:28 a.m. it moved between 23 and 28 cents in small trades.
The release
At 8:30 a.m. the Labor Department reported that producer prices rose 1.3% in September, more than double the forecast and the largest increase since March 2022. Retail sales, released at the same moment, also beat expectations.
Six seconds later, about 15,000 contracts changed hands at 30 cents. By 8:32 a.m. a 15,000-contract buy had traded at 36 cents, and 20 seconds after that the price touched 37 cents, the day's high. At 8:34 a.m. the largest single print of the session went through: 50,000 contracts bought at 34 cents.
The fade
The spike did not last. By 8:48 a.m. the contract traded at 29 cents. At 9:01 a.m. a seller hit 4,800 contracts at 29 cents, and at 9:20 a.m. a block of about 10,500 traded at 28 cents. From then until early afternoon the price held at 28 to 29 cents in small lots. The last trade before 1:46 p.m. was at 29 cents.
Before dawn, the contract had already given back most of Wednesday's consumer-price jump. Thursday's data offered a test of that retreat: a move back into the mid-30s would have reversed it. The contract reached that zone for a few minutes and then fell back. At 29 cents, it sat a cent above the top of its pre-release range.
What else was moving
The fade came as other markets turned in the same direction. The 10-year Treasury yield fell about 9 basis points to just under 5.1% by mid-morning, its lowest since Sept. 24, as investors bought bonds during a selloff in AI-linked stocks. CME FedWatch readings during the morning put the probability of an October increase between about 27% and 34% after the release, against just under 30% before it.
Fed officials have also been signaling patience. San Francisco Fed President Mary Daly said Wednesday that more increases are likely needed but not necessarily in October. Fed Governor Christopher Waller said last week that further increases "do not need to come at consecutive meetings," though they should be in place within an acceptable period.
None of that establishes why traders sold the spike back. The sequence is clear; the cause is not.
The 50,000-contract print
The largest trade of the window came four minutes after the data were public, so its timing does not raise questions about advance knowledge. It does show that at least one participant was willing to commit size at 34 cents, near the top of the move, and that buyer was underwater within 15 minutes.
Market implications
One reading is that the market is anchored by the Fed's own messaging. Officials have framed the next increase as likely but not urgent, and two hot inflation reports in two days have not changed the October price much once the first reaction passed.
A second reading is that the market is underpricing the risk. Producer prices are running at 6.3% a year, services inflation is broadening, and the brief spike to 37 cents shows how quickly sentiment can shift. A contract at 29 cents implies the market sees roughly a 3-in-10 chance of an October increase under Kalshi's rules, which would leave room for a sharp repricing if Fed officials sound more urgent.
What to watch
Fed Chair Kevin Warsh's remarks late Thursday Eastern time are the last major scheduled Fed communication before the blackout period. Any shift in his tone would be visible first in this contract.
