Macro-level cryptocurrency market capitalisation and asset class rotation dynamics represent some of the most heavily wagered positions in crypto prediction markets. These venues attract strategists focused on portfolio-wide movements and broad ecosystem trends, sidestepping single-token exposure.
Total Crypto Market Cap Markets
Live PolyGram odds 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, it has traditionally marked the onset of altcoin rallies — this probability is continuously reflected across active markets.
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 ecosystems tend to cycle through distinct phases:
- 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)
Wagering on BTC dominance shifts and altcoin season metrics functions as a forward-looking play on these rotation cycles — positioning ahead of when price discovery fully catches up to the underlying rotation.
FAQ
- How is "altcoin season" defined for prediction market purposes?
- The CoinMarketCap Altcoin Season Index serves as the standard benchmark — readings above 75 suggest altcoins have been gaining on Bitcoin over the preceding 90-day window.
- What data is used for total market cap resolution?
- 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.
