Fed rate hike by 2026?

Platform comparison

Market context

The underlying event is whether the Federal Reserve will raise the upper bound of its target federal funds rate between December 2025 and late 2026, a move that currently carries zero crowd-implied probability. Historical precedent strongly supports this null outlook: the Fed cut rates by 75 basis points in 2025, including a 25-point reduction in December 2025, and maintains a clear bias toward further slashing in 2026 as labour market weakness persists[1][3]. Since 2024, the policy trajectory has been exclusively downward, with no rate hikes recorded in the last three meetings, making a sudden reversal to tightening highly anomalous unless inflation data dramatically deteriorates[4][6].

Traders should monitor the 5 December PCE inflation data, the Fed’s key gauge, alongside the December FOMC statement, dot plot, and Powell’s press conference for any unexpected hawkish signals[2]. The blackout period from 29 November to 11 December 2025 will limit information flow, increasing volatility around the 9–10 December meeting[2]. Platform comparisons reveal divergent approaches: Polymarket displays decimal odds (0.00) while Kalshi and Betfair emphasise implied probability (0%), and fee structures vary significantly, with some platforms requiring KYC that restricts access for international users[1]. These structural differences mean liquidity and pricing efficiency may differ markedly across exchanges for this specific zero-probability event.
