In the fog of prediction markets, seize the Wofford vs Mercer mismatch—profit awaits the cunning strategist ready to strike.
What is Prediction Market Arbitrage?
Arbitrage is a strategy for risk-free profit by exploiting price differences for the same asset across different platforms. In prediction markets, this means buying contracts on opposite outcomes on different platforms when the sum of prices is less than 100%.
Real Example: Wofford vs Mercer (NCAA Basketball)
Game Date: January 24, 2026, 7:00 PM EST
Kalshi Prices:
- Wofford — Yes 55¢ (53% probability)

- Total: 102¢ (2% overpriced)
Polymarket Prices:
- Mercer Bears — 55¢
- Wofford Terriers — 46¢

Arbitrage Opportunity
Price Difference:
| Team | Kalshi | Polymarket | Difference |
|---|---|---|---|
| Wofford | 55¢ | 46¢ | +9¢ |
| Mercer | 47¢ | 55¢ | -8¢ |
Strategy:
- Buy Wofford on Polymarket for 46¢
- Buy Mercer on Kalshi for 47¢
- Total cost: 93¢
- Guaranteed win: $1.00 (one contract will definitely win)
- Net profit: 7¢ per dollar (7.5% ROI)
Why Price Differences Exist?
- Different liquidity — Kalshi volume ($1,030) is much smaller than Polymarket
- Different audience — Kalshi is CFTC-regulated and US-only
- Reaction time — markets dont always sync instantly
- Fees — different fee structures affect real returns
Arbitrage Risks
- Platform fees can eat into profits
- Execution time — prices may change while placing orders
- Withdrawal limits — funds may be locked on different platforms
- Regulatory risks — not all platforms available in all jurisdictions
Conclusion
Prediction market arbitrage is a real profit opportunity but requires:
- Fast execution
- Accounting for all fees
- Capital on multiple platforms
- Understanding regulatory limitations
