Prediction markets extending beyond individual token valuations encompass the aggregate cryptocurrency market capitalisation and how capital shifts between different asset classes. These venues attract investors focused on portfolio-wide positioning who seek exposure to overarching crypto dynamics whilst avoiding concentration in particular holdings.
Total Crypto Market Cap Markets
PolyGram market pricing 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 45%, this conventionally marks the beginning of altcoin season — prediction markets continuously track this threshold's likelihood.
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 typically progress through cyclical movements:
- BTC leads (dominance expands, funds migrate away from alternative coins toward Bitcoin)
- ETH follows BTC (Ethereum gains ground as Bitcoin enters consolidation)
- Altcoin season (funds shift from Bitcoin and Ethereum toward emerging projects)
Markets tracking Bitcoin dominance and altcoin season metrics function as advance signals of these rotational shifts — often moving ahead of the underlying price developments that eventually validate the transition.
FAQ
- How is "altcoin season" defined for prediction market purposes?
- The majority of venues employ the CoinMarketCap Altcoin Season Index — readings above 75 suggest alternative coins are delivering stronger returns than Bitcoin across the preceding 90-day window.
- What data is used for total market cap resolution?
- CoinGecko or CoinMarketCap aggregate market capitalisation figures (omitting stablecoins and certain digital assets) recorded on the designated date at midnight UTC.
- Are there layer-1 vs layer-2 sector markets?
- PolyGram introduces dedicated sector-specific rotation markets during periods when significant volume-driving developments emerge — L1 protocol competition, decentralised finance total value locked milestones, non-fungible token trading volume benchmarks.
