Fed decisions (Jun-Sep)

Platform comparison

Market context

The Federal Reserve is expected to raise, not cut, interest rates across its June, July, and September 2026 meetings, with the current 0% crowd-implied probability for a cut reflecting official hawkishness. The June FOMC meeting already held rates steady at 3.50%–3.75% but flipped the dot plot from cuts to hikes, with nine of eighteen officials now projecting at least one increase before year-end [1][3]. Minutes released in July confirmed no cuts until early 2027, while renewed Middle East tensions—specifically Iran conflict risks—have pushed September hike odds to approximately 70% [2].

Historically, such a rapid pivot from cut expectations to hike projections occurs only when inflation overshoots persistently or external shocks disrupt supply chains. The March 2026 dot plot had suggested potential cuts, yet by June, inflation forecasts surged to 3.6%, forcing officials to abandon easing plans entirely [3]. This mirrors the 2022–2023 tightening cycle, where geopolitical stress and sticky inflation compelled the Fed to tighten despite earlier dovish signals. The current 0% probability for a cut aligns with this precedent, as markets now price a 25-basis-point hike by September rather than any reduction [2][4].

Traders should monitor the July 28–29 FOMC minutes and the September 15–16 dot plot release, which will clarify whether the hike trajectory holds. CME Group’s FedWatch tool shows hike expectations soaring 853% since December, with the median year-end rate projection climbing to 3.8% [2][3]. On Polymarket versus Kalshi, the divergence lies in format: Polymarket uses implied probability (0% YES here), while Kalshi displays decimal odds and charges different fees; both require KYC, but Kalshi’s US-only reach contrasts with Polymarket’s global access. Smarkets and Betfair, meanwhile, offer decimal odds without probability conversion, appealing to traders preferring traditional bookmaking styles.
