Macro-level prediction markets focused on aggregate cryptocurrency market capitalisation and cross-sector capital flows attract traders who think in portfolio terms, seeking broad exposure to crypto movements rather than individual token bets.
Total Crypto Market Cap Markets
PolyGram market odds as of 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, it has traditionally marked the onset of altcoin season — prediction markets continuously reflect this probability in real time.
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 cyclical phases of capital reallocation:
- 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)
Markets tracking BTC dominance and altcoin season metrics function as forward-looking signals for these rotation phases — allowing traders to position ahead of price discovery in the underlying assets.

- CoinGecko or CoinMarketCap total market cap (excluding stablecoins and certain tokens) on the specified date at midnight UTC.
- Are there layer-1 vs layer-2 sector markets?
- PolyGram lists specific sector rotation markets when high-volume events drive interest — L1 competition, DeFi TVL milestones, NFT market volume targets.
