Macro-level cryptocurrency prediction markets focus on aggregate market capitalisation and how capital shifts between asset categories, drawing in traders who think in portfolio terms and seek broad exposure to the crypto ecosystem without committing to individual tokens.
Total Crypto Market Cap Markets
PolyGram pricing snapshot (May 2026):
- Total crypto market cap over $4T in 2026: ~62-68%
- Total crypto market cap over $5T in 2026: ~38-44%
- Total crypto market cap new all-time high in 2026: ~55-62%
Bitcoin Dominance Markets
- BTC dominance over 60% at year-end: ~30-35%
- BTC dominance under 40% at year-end: ~25-30%
When Bitcoin dominance falls beneath the 45% threshold, altcoin season typically emerges — this dynamic is continuously reflected in live market odds.
Altcoin Season Prediction Markets
- Altcoin Season Index over 75 by Q4 2026: ~42-48%
- Ethereum outperforms Bitcoin in 2026: ~40-46%
- Solana market cap surpasses Ethereum in 2026: ~12-16%
Sector Rotation Trading Strategy
Cryptocurrency markets move through recognisable cycles of capital allocation:
- BTC leads (dominance rises, capital flows from alts to BTC)
- ETH follows BTC (Ethereum catches up as BTC consolidates)
- Altcoin season (capital flows from BTC/ETH to smaller caps)
Traders use prediction markets on Bitcoin dominance and altcoin season metrics as advance signals of these rotation cycles — positioning ahead of when price movements fully capture the shift.
