The prediction market platform Kalshi is flashing a warning that most crypto traders probably aren’t watching closely enough. As of June 18, traders on the CFTC-regulated platform placed 57% odds on the Federal Reserve delivering a rate hike before the end of 2026. That’s up from 35% just two days earlier.
What happened at the FOMC meeting
The Federal Reserve, now under the chairmanship of Kevin Warsh, held rates steady at its June 17 meeting. Kalshi traders had priced that outcome at 99% ahead of the announcement.
The Fed bumped its inflation forecast to 3.6%, a number that suggests price pressures remain stubbornly above the central bank’s 2% target. Out of 18 FOMC members, nine projected at least one rate hike before the end of 2026. Six of those nine went further, penciling in two hikes.
Kalshi’s growing influence on rate expectations
A Federal Reserve working paper published in February 2026 found that Kalshi’s forecasts for rate decisions actually outperformed traditional fed funds futures in accuracy. The platform maintained a perfect track record ahead of FOMC meetings, according to that same paper.
Trading volume on Kalshi’s rate-related markets exceeded $3.2 million around this latest FOMC decision. Beyond the 2026 timeline, Kalshi traders placed a 52% chance on the next hike happening before 2027. Push the window out to July 2027 and those odds climb to 62%. By the end of 2027, the probability hits 76%.
Why crypto investors should care deeply about this
Bitcoin and the broader crypto market have a complicated but undeniable relationship with monetary policy. When the Fed was cutting rates and flooding markets with liquidity in 2020 and 2021, Bitcoin went from roughly $7K to $69K. When the Fed reversed course and started hiking aggressively in 2022, Bitcoin dropped below $16K.
A 3.6% inflation forecast is not the kind of number that leads to rate cuts. Higher rates strengthen the dollar, which historically puts pressure on Bitcoin. They increase the opportunity cost of holding non-yielding assets.
Traders who use Kalshi data as a leading indicator, and the Fed’s own research suggests they should, might want to start stress-testing their portfolios against a scenario where rates move higher in the second half of 2026. The odds aren’t overwhelming at 57%, but they’ve nearly doubled in 48 hours.
