Macro-level cryptocurrency prediction markets extend well beyond individual token valuations, encompassing total market capitalisation and the cyclical shifts between asset classes. These venues attract investors focused on portfolio-wide strategies, seeking broad exposure to cryptocurrency movements whilst avoiding concentration in any single asset.

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's share of total market value dips beneath 45%, this conventionally marks the onset of altcoin season — prediction markets continuously reflect the likelihood of this threshold being breached.

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 recognisable cycles:

  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)

Markets tracking Bitcoin dominance and altcoin season metrics function as forward-looking signals for these rotation phases — enabling traders to position ahead of actual price discovery across the broader ecosystem.

FAQ

How is "altcoin season" defined for prediction market purposes?
The CoinMarketCap Altcoin Season Index serves as the standard reference — readings above 75 signify that alternative cryptocurrencies have outpaced Bitcoin's returns over the preceding 90-day window.
What data is used for total market cap resolution?
Resolution typically relies on CoinGecko or CoinMarketCap figures for aggregate market capitalisation (excluding stablecoins and certain token categories) as recorded on the contract date at 00:00 UTC.
Are there layer-1 vs layer-2 sector markets?
PolyGram introduces targeted sector markets when significant liquidity drivers emerge — L1 competitive dynamics, DeFi total value locked milestones, or NFT trading volume thresholds.
