Polymarket News Today: US CPI Data Release and Its Impact on Fed Rate Polymarket news today is dominated by one number: 3.7%. That’s where US inflation landed in September, and it hit the cry
Polymarket news today is dominated by one number: 3.7%. That’s where US inflation landed in September, and it hit the cryptocurrency market and the Federal Reserve’s October decision odds within minutes. Bitcoin traders watched the Consumer Price Index print hotter than expected, and bettors on Polymarket rushed to reprice the Fed’s next move. Odds on the “Fed Decision in October 2026” contract swung by double digits in under an hour, and a separate market tracking another Fed rate hike in 2026 moved just as fast.
Key Takeaways
The Bureau of Labor Statistics reported that Consumer Price Index for All Urban Consumers climbed 0.6% in September on a seasonally adjusted basis. That’s up from a 0.4% rise in August. Over the past 12 months, prices rose 3.7%, the fastest annual pace since May and above the 3.6% economists expected.
Core CPI, which strips out food and energy, told a similar story. It rose 2.6% year over year, the highest since June, above the 2.5% forecast. Core CPI rose 0.3% month over month on a seasonally adjusted basis, also hotter than the 0.2% expected. Unadjusted CPI for the month rose 0.6%, the biggest monthly jump since April.
The crypto market and Federal Reserves felt it fast.
Polymarket news today centers on this exact swing. Before the CPI report landed, bettors priced an 80% chance of no rate change in October and just 20% for a 25 basis point hike. The hot data flipped that script in minutes.

Fed Decision in October 2026 Before CPI Right After CPI At Time of Writing No Change 80% 52% 72% 25 bps Hike 20% 48% 28%“No change” odds crashed to 52%, and hike odds surged to 48%, almost a coin flip. Odds later cooled, and at the time of writing, “no change” sits at 72%, with hike odds back at 28%. This kind of fast repricing is exactly why Polymarket betting around a meeting date draws so much attention, and why Polymarket prediction market activity moves crypto prices too.
Fed Chair Kevin Warsh faces a tight spot. As analyst Crypto Rover pointed out, the employment picture is already soft, while inflation runs hot at the same time. If the Fed holds rates, inflation could keep climbing. If it hikes, employment could weaken further. Neither path comes free.
This second Polymarket storyline moves on its own track, and it tells you just as much about trader nerves as the October decision does. Before the September CPI release, the market pricing another Fed rate hike in 2026 hovered between 76% and 81%, a wide but fairly calm range that had held for weeks.

That calm broke the moment the CPI numbers hit the wire. Odds for a 2026 hike spiked to 89% within the same window that “no change” odds for October were crashing. Traders read the hot core CPI print as proof that one hike this October might not be the end of the story. A second move before year-end suddenly looked far more likely than it had the day before.
Since then, the number has eased back to 82% at the time of writing. That’s still sharply above the pre-CPI range of 76% to 81%, which tells you the market hasn’t fully walked back its hawkish reaction, even as the October-specific odds cooled faster.
The CPI report is out, but the volatility isn’t done. September’s Producer Price Index releases Thursday, October 15. Kevin Warsh is also scheduled to speak the same day. Both events could swing crypto prices again, and both will shape the Fed’s meeting on October 27 and 28.
Expert Opinion: Analysts tracking Polymarket betting note that prediction markets often overreact to a single data point before settling closer to the longer trend, a pattern visible in both the Decision and rate hike contracts this week. The gap between the 52% low and the 72% recovery shows how fast sentiment snaps back once early panic fades.
Still, with core CPI running hot and the labor picture soft, the setup into the October 27-28 meeting stays unusually tight, and the coming PPI print could move the needle again.
Polymarket news today boils down to one theme: inflation surprised to the upside, and bettors reacted fast. Decisions cooled from their post-CPI spike, but the road to October 27-28 isn’t settled. With PPI data and Kevin Warsh’s comments due Thursday, expect these odds to keep moving.
