Macro-level cryptocurrency prediction markets extend well beyond individual token valuations, encompassing aggregate market capitalisation and cyclical sector shifts. These venues attract investors focused on portfolio-wide positioning who seek broad-based crypto exposure through thematic bets rather than concentrated single-asset wagers.

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, it typically marks the onset of altcoin season — this dynamic is continuously 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

Cryptocurrency markets characteristically cycle through distinct phases:

  1. BTC leads (dominance rises, capital flows from alts to BTC)
  2. ETH follows BTC (Ethereum catches up as BTC consolidates)
  3. Altcoin season (capital flows from BTC/ETH to smaller caps)

Traders utilise prediction markets on BTC dominance and altcoin season indicators as forward-looking signals of these rotation phases — capturing opportunities before price discovery fully incorporates the sectoral shift.

FAQ

How is "altcoin season" defined for prediction market purposes?
The CoinMarketCap Altcoin Season Index serves as the standard reference metric — readings above 75 signify that alternative cryptocurrencies have outpaced Bitcoin's performance over the preceding 90-day window.
What data is used for total market cap resolution?
CoinGecko or CoinMarketCap aggregate market capitalisation (excluding stablecoins and select tokens) as recorded on the settlement date at midnight UTC.
Are there layer-1 vs layer-2 sector markets?
PolyGram introduces specialised sector rotation markets during periods of elevated trading activity — these cover L1 competitive dynamics, DeFi total value locked thresholds, and NFT transaction volume benchmarks.
