Talos: Top 10 tokens made up 62% of altcoin futures open interest, raising cross-collateral risk
Talos said in an October 1 weekly report covering September 24–30 that the top 10 tokens accounted for 62% of altcoin futures open interest, highlighting sharp concentration. Funding rates also diverged in the same period, with SOL below zero and PUMP at +21.8% annualized, before reversing direction within the following four hours. The report put altcoin open interest relative to market capitalization at 5.6%, a record within Talos’s series. It also warned that shared collateral mechanisms can allow stress in a single asset to spill over to other positions, increasing systemic risk.
