Macro-level cryptocurrency prediction markets extend well beyond individual token valuations, encompassing total market capitalisation and the cyclical shifts between asset categories. These venues attract strategists focused on portfolio-wide exposure to the broader digital asset ecosystem, enabling participation in large-scale trends whilst sidestepping concentration risk in single projects.

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's share of total market value falls beneath 45%, altcoin season typically emerges — this threshold is continuously monitored and priced across active prediction venues.

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

Digital asset markets move through recognisable cyclical patterns:

  1. BTC leads (dominance climbs, liquidity shifts away from alternative tokens toward Bitcoin)
  2. ETH follows BTC (Ethereum gains ground as Bitcoin enters consolidation phases)
  3. Altcoin season (liquidity migrates from major cryptocurrencies into smaller-cap projects)

Traders can deploy prediction markets tracking BTC dominance and altcoin season metrics as advance signals of these rotation cycles — capturing opportunities before price discovery fully absorbs the directional shift.

FAQ

How is "altcoin season" defined for prediction market purposes?
The CoinMarketCap Altcoin Season Index serves as the standard reference — readings above 75 suggest alternative tokens have outpaced Bitcoin's performance across the preceding 90-day window.
What data is used for total market cap resolution?
Resolution relies on total market capitalisation figures from CoinGecko or CoinMarketCap (omitting stablecoins and designated token categories) recorded at the specified settlement date, midnight UTC.
Are there layer-1 vs layer-2 sector markets?
PolyGram introduces tailored sector rotation contracts during periods of elevated trading demand — typically coinciding with L1 protocol competition, DeFi total value locked milestones, or non-fungible token volume thresholds.
