This Week’s Top Prediction Markets: December 2-8, 2025

Every week, prediction market odds shift dramatically as news breaks, events unfold, and traders update their forecasts. This week (December 2-8, 2025) brings critical trading opportunities across politics, economics, crypto, and sports as year-end approaches and 2028 presidential positioning intensifies. We analyze this week’s highest-volume markets on Polymarket, Kalshi, and PredictIt, identify major odds movements, and highlight where smart money is flowing.

Whether you’re tracking Federal Reserve policy, Bitcoin’s push toward $150,000, or early 2028 primary odds, this weekly analysis gives you actionable intelligence on current live prediction markets.

This Week’s #1 Market: Federal Reserve Rate Decision (Dec 9-10)

Volume: $15.8M on Kalshi, $8.2M on Polymarket
Current Odds: 82% probability of 25-basis-point cut
Resolution: December 10, 2024 (FOMC announcement)

The highest-volume economic market this week centers on the Federal Reserve’s final 2024 policy meeting. Odds jumped from 65% to 82% over the past week following dovish commentary from Chair Powell and softer inflation data. Kalshi’s Fed rate market dominates volume with $15.8 million in positions—the largest single economic market of December.

Why It’s Hot: Year-end Fed decisions historically drive significant market volatility across equities, bonds, and crypto. The 82% probability reflects strong consensus, but the remaining 18% uncertainty represents $3+ million in NO positions from traders betting the Fed pauses rate cuts due to persistent inflation concerns.

Trading Insight: At 82% odds ($0.82 per YES share), potential return is limited (22% max if correct) but probability is high. This suits risk-averse traders seeking high-confidence plays. Contrarians betting NO at $0.18 face longer odds but could see 456% returns if Fed surprises by holding rates steady.

Watch For: Wednesday’s (Dec 4) ADP employment data and Friday’s (Dec 6) official jobs report. Strong employment data could push odds back toward 75%, creating entry points for YES buyers.

#2: Bitcoin Reaches $150,000 by Year-End

Volume: $4.8M on Kalshi, $3.2M on Polymarket
Current Odds: 38% probability (YES at $0.38)
Resolution: December 31, 2024 (CoinMarketCap closing price)

Bitcoin’s dramatic 2024 rally (currently ~$128,000) has traders speculating whether $150K is achievable in under 30 days. Odds surged from 28% to 38% following BlackRock’s announcement of record ETF inflows, representing a 10-point swing in 48 hours. Crypto prediction markets show this as the week’s most volatile high-volume contract.

Why It’s Hot: Bitcoin needs 17% appreciation in 29 days—ambitious but historically plausible given Bitcoin’s volatility. The market is split: bulls point to institutional inflows, potential Fed rate cuts boosting risk assets, and year-end window dressing by funds. Bears cite current resistance at $130K, profit-taking after a strong 2024, and macroeconomic headwinds.

Trading Insight: High risk/high reward. Buying YES at $0.38 offers 163% return if Bitcoin hits target but total loss if it doesn’t. The 38% odds reflect genuine uncertainty rather than clear consensus. This suits risk-tolerant traders with conviction on Bitcoin’s near-term trajectory.

Watch For: This week’s Fed decision directly impacts crypto risk appetite. A rate cut could catalyze the rally needed for $150K; a pause could kill momentum. Also monitor institutional ETF flow data published weekly.

#3: 2028 Republican Presidential Primary Leaders

Volume: $12.4M combined across all candidates (Polymarket)
Current Odds: DeSantis 35%, Haley 28%, Ramaswamy 18%
Resolution: Summer 2028 (primary results)

With Trump announcing no 2028 run, political prediction markets surged 300% in weekly volume as the Republican field opened. DeSantis odds dropped from 42% to 35% this week following criticism of his debate performance, creating the largest single-week movement in presidential markets since the 2024 election concluded.

Why It’s Hot: Early positioning for 2028 offers value opportunities before polling and fundraising data solidify. Current odds reflect name recognition and media coverage more than actual campaigning (which hasn’t begun). Sophisticated traders identify mispriced candidates based on fundamental strengths polling doesn’t yet capture.

Trading Insight: Long-term hold (3+ years until resolution) creates significant risk from changing dynamics. However, early entry captures better odds than waiting. DeSantis at 35% ($0.35) could return to 45-50% if he addresses debate weaknesses, offering 40%+ upside. Ramaswamy at 18% ($0.18) represents high-variance bet on outsider momentum.

Watch For: Q4 2024 fundraising reports (released late December) show which candidates have financial staying power. Early polling from Iowa and New Hampshire (starting early 2025) will shift odds significantly.

#4: NFL Super Bowl LX Champions

Volume: $6.2M (distributed across teams)
Current Odds: 49ers 22%, Chiefs 19%, Bills 16%, Eagles 13%
Resolution: February 9, 2025 (Super Bowl result)

Sports prediction markets dominate post-election volume, with NFL championship odds shifting weekly based on game results and playoff positioning. The 49ers overtook the Chiefs this week following Kansas City’s loss to Green Bay, creating a 3-point odds swing (Chiefs 22% → 19%, 49ers 19% → 22%).

Why It’s Hot: Playoff picture crystallizing creates value opportunities as odds adjust to current form rather than preseason projections. The market is remarkably balanced—top 4 teams combine for only 70% probability, leaving 30% distributed among long shots. This fragmentation creates arbitrage possibilities across platforms.

Trading Insight: Team performance next two weeks determines playoff seeding, dramatically impacting Super Bowl odds. Buying current favorite (49ers at 22%) offers modest 4.5x payout but high probability. Buying Bills at 16% offers 6.25x payout with strong fundamentals (best point differential in AFC). Avoid teams below 5% unless you have specific injury/matchup intelligence.

Watch For: Week 14-15 games determine playoff seeding. Home-field advantage shifts odds 5-10 percentage points. Injury news to star players (especially QBs) creates immediate odds movements.

#5: Oscars Best Picture Winner 2025

Volume: $2.8M on Polymarket
Current Odds: “Oppenheimer” 42%, “Killers of the Flower Moon” 28%
Resolution: March 10, 2025 (Academy Awards ceremony)

Entertainment prediction markets see rising volume as awards season begins. “Oppenheimer” maintains frontrunner status at 42% but “Killers of the Flower Moon” climbed from 22% to 28% this week following Golden Globe nominations announcement.

Why It’s Hot: Awards markets offer pure information trading—outcomes determined by predictable voting patterns rather than random events. Historical data on Academy voting preferences, guild award correlations, and nomination counts provide analytical edges unavailable in sports or political markets.

Trading Insight: “Oppenheimer” at 42% ($0.42) implies 58% chance it doesn’t win, despite being clear favorite. Historical analysis shows Best Picture favorites with 40%+ odds pre-nominations win 75% of the time, suggesting current odds undervalue “Oppenheimer.” “Killers” at 28% offers value if you believe Scorsese’s directorial reputation and strong guild support translate to Academy votes.

Watch For: December 11 Critics Choice nominations and January 7 Critics Choice Awards. These precursor awards historically predict 85% of eventual Best Picture winners.
