🧠 Top Moves Today
🟩 Fed Rate Cut Back on Table
Polymarket traders now see a 50% chance of a Fed interest rate cut in September — a sharp jump, triggered by former President Trump urging Fed Chair Jerome Powell to resign (CoinDesk, 2025a). Odds of no change at the July meeting sit at ~96%, echoing CME FedWatch data.
🟥 Recession Fears Ebbing
The perceived odds of a U.S. recession in 2025 have plunged to ~22% on Polymarket (CoinDesk, 2025b). That’s the lowest level since February. In April, odds hit 66% amid tariff fears, but easing U.S.–China tensions have shifted sentiment.
🎾 Wimbledon Shake-Up
Carlos Alcaraz is now favored ~52% to win the 2025 men’s title, ahead of Sinner and Djokovic. Traders have downgraded Djokovic (~17%) after a tough semifinal (Polymarket, 2025).
🤖 AI Leadership Race Tightens
On Manifold, traders still rank Google’s Gemini as the most likely to lead by year-end, but Elon Musk’s xAI is gaining fast, shrinking the odds gap (Manifold, 2025a).
🔍 Market to Watch: Nathan’s Hot Dog Contest 🌭
The Nathan’s Famous Hot Dog Eating Contest brought serious action to prediction markets last week. Reigning champ Joey Chestnut had ~95% odds to win (Kalshi, 2025a), so traders turned to totals: Would he eat over 70 dogs?
Kalshi traders priced a 71% chance he’d hit 70+ — but only a ~33% chance he’d top 75 (Kalshi, 2025b). Chestnut landed in the low 70s, right in line with market expectations. This offbeat contest ended up being ~4% of Kalshi’s total volume last week, showing how cultural events can drive real predictive activity.
💰 Smart Bet of the Day: Fading Tether Panic
Polymarket shows a 16% chance that Tether (USDT) will lose its peg in 2025, and 11% chance of full insolvency (Polymarket, 2025b). Historically, Tether has maintained stability despite controversies.
If you believe the panic is overblown, this market may be mispriced. Betting “No” on a Tether collapse could yield strong value — if history repeats and the peg holds. (Not financial advice.)

🧵 From the Community
“Try not to overtrade. This is both bad on its own and makes interpreting the data harder.”
— Evan B. on Manifold’s forecasting advice thread (Manifold, 2025c)
Manifold’s top predictors say patience often outperforms panic. A strong reminder that conviction > reaction.
