February 2026: All-Time Record Month
Polymarket shattered its previous records in February 2026, driven largely by geopolitical events:
| Metric | Record | Context |
|---|---|---|
| Monthly Volume | $7B+ (February 2026) | 7.5x year-over-year increase |
| Single-Day Volume | $425M (February 28, 2026) | Day of US-Iran military strikes |
| Largest Single Market | $529M (US strikes Iran) | Biggest prediction market contract ever |
| Prediction Accuracy | 94% (1-month score) | Markets correctly predicting outcomes |
Monthly Volume Trend
Polymarket's monthly volume has shown explosive growth:
- 2024 Peak: Driven by the US Presidential Election (November 2024)
- Early 2025: Post-election decline, then steady recovery
- November 2025: Surge after US market re-opening (CFTC approval)
- January 2026: Strong growth across categories
- February 2026: $7B+ all-time record, fueled by Iran conflict and crypto volatility
Volume by Category
Top Categories by 24-Hour Trading Volume (March 2026)
| Category | 24h Volume | Active Markets |
|---|---|---|
| Sports | ~$97.5M | Thousands |
| Crypto | ~$18.6M | 4,026 |
| Politics & Geopolitics | ~$6.8M | Hundreds |
| AI & Technology | Varies | 200+ |
Notable Category Trends
Sports has emerged as the dominant daily volume category, surpassing politics during non-election periods. Polymarket's partnership with Betr (announced March 2026) will bring prediction markets to Betr's 1 million paying users, likely increasing sports volume further.
AI Model Markets peaked at $36.33M in December 2025 and have been declining — $28.97M in January, $21.66M in February. Anthropic's Claude Opus 4.6 is the Arena #1 incumbent, with the monthly "Best AI Model" market drawing consistent interest.
Geopolitics generates the largest individual market volumes. While daily volume is lower than sports, single geopolitical events can produce $100M+ markets that dwarf any individual sports contract.

Polymarket's Competitive Position
Polymarket leads the prediction market space, but faces growing competition:
- Kalshi: Also CFTC-regulated, strong in finance/economics markets
- Manifold Markets: Play-money platform with large community
- Augur / Gnosis: Decentralized alternatives
Polymarket's advantages include its massive liquidity, broad market coverage (sports, politics, crypto, AI, culture), and CFTC regulatory approval for US users.
What Drives Polymarket's Volume?
1. Major Events Create Spikes
The pattern is clear: major world events drive massive volume spikes. The 2024 election and the 2026 Iran conflict both generated hundreds of millions in single-market volume.
2. Crypto Market Correlation
Polymarket uses USDC on the Polygon blockchain. When crypto markets are active, Polymarket tends to see more deposits and trading activity. Bitcoin's volatility in early 2026 (dropping from $100K+ to $60K, then recovering) correlated with increased Polymarket activity.
3. US Market Re-Opening
The November 2025 CFTC approval was a game-changer. US traders — the largest potential user base — can now legally use the platform, contributing to the volume growth seen in late 2025 and into 2026.
4. Sports Expansion
The addition of comprehensive sports markets has diversified Polymarket's volume base beyond politics and crypto, providing consistent daily volume.
