Macro-level cryptocurrency prediction markets extend well beyond individual token valuations, encompassing aggregate market capitalisation and the cyclical shifts between asset categories. These instruments attract investors focused on portfolio-wide strategies, enabling them to gain exposure to overarching crypto movements whilst sidestepping concentration risk in particular holdings.

Total Crypto Market Cap Markets

PolyGram's current market quotations (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 retreats beneath the 45% threshold, it has traditionally marked the emergence of altcoin season — prediction platforms continuously reflect this likelihood in real-time pricing.

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 have historically moved through distinct cyclical stages:

  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 can leverage prediction market contracts on Bitcoin dominance and altcoin season metrics as advance signals of these rotational transitions — capturing value before conventional price discovery fully incorporates the directional shift.

FAQ

How is "altcoin season" defined for prediction market purposes?
The CoinMarketCap Altcoin Season Index serves as the standard reference for most markets — readings above 75 signify that altcoins have outpaced Bitcoin's performance during the preceding 90-day window.
What data is used for total market cap resolution?
Resolution relies on total market cap figures from CoinGecko or CoinMarketCap (with stablecoins and select tokens excluded) as recorded on the contract maturity date at 00:00 UTC.
Are there layer-1 vs layer-2 sector markets?
PolyGram introduces dedicated sector rotation markets in response to heightened trading demand around significant catalysts — including L1 competitive dynamics, DeFi total value locked milestones, and NFT trading volume benchmarks.
