> The altcoin open-interest-to-market-cap ratio reached 5.6%, its highest level in the tracked series.

The 10 largest altcoins by open interest represented 62% of tracked altcoin open interest in the week ended Sept. 30, while the reported open-interest-to-market-cap ratio reached 5.6%. The aggregate figures show concentration in the tracked market but do not identify risks in individual accounts.

The weekly snapshot covered Sept. 24-30. Solana (SOL), XRP, HYPE and Zcash (ZEC) were among the largest altcoins by open interest.

The 5.6% ratio was the highest in the tracked series.

The aggregate measures do not identify traders’ leverage, collateral arrangements or individual liquidation risk. They show the share of tracked altcoin open interest represented by the 10 largest altcoins, not how a loss in one position might affect a particular trader’s other holdings.

Margin mechanics vary by venue and account setup. On Hyperliquid, cross margin shares collateral among eligible cross-margin positions, while isolated margin limits collateral to a specific position. The effect of cross margin can depend on account mode and the markets involved; liquidation rules also depend on account value and maintenance margin.

The snapshot covers a week in late September and does not establish how concentration changed after Sept. 30.
