S&P reaffirms US AA+ as Polymarket lifts July Fed hold odds to 80.5%

Fed July 2026 Rate Decision: “No Change” Jumps to 80.5% After S&P Reaffirms U.S. AA+ Rating

Polymarket traders boosted the implied probability of the Federal Reserve holding rates steady after the July 2026 meeting, pushing the “No change” contract to 80.5% from 71.5%. The repricing came as S&P reaffirmed the U.S. sovereign credit rating at AA+ and kept its outlook stable.

Key Takeaways

• Polymarket prices an 80.5% chance the Fed makes no change after the July 2026 meeting.
• Odds moved up 9.0 points as traders digested S&P’s affirmation of the U.S. AA+ rating and stable outlook.
• The contract is set to resolve on 2026-07-29, and the market’s 7-day change shows a -2.0 point move.

S&P affirmed the United States’ sovereign credit rating at AA+ and maintained a stable outlook, according to a report published on June 27, 2026. The rating action signals no change to S&P’s assessment of the government’s current standing at that grade. A stable outlook typically indicates the agency does not expect to revise the rating in the near term under its baseline scenario. The update comes as investors monitor fiscal and macroeconomic conditions that can influence risk pricing across Treasury markets and broader financial conditions. The reaffirmation leaves the U.S. below the agency’s top-tier rating while keeping its forward-looking view unchanged.
