ARK's Nicholas Grous maps $5T prediction market opportunity
ARK Invest research director Nicholas Grous outlined a $5 trillion total addressable market for prediction markets in a July 27 video interview with Yahoo Finance. Grous, who leads research for consumer internet and fintech at the firm, argued the sector sits at the intersection of finance and technology. The $5 trillion figure represents ARK's estimate of the sector's untapped potential. Grous described the opportunity as massive.
The $5 trillion figure gives institutional allocators a concrete anchor for sizing prediction markets against traditional derivatives. Grous's ARK platform can move retail sentiment and ETF flows, which means the call may pull capital toward CFTC-regulated venues before the regulatory picture clears.
For Kalshi and Polymarket, that attention is a double edge: more capital helps them compete, but a $5 trillion headline also invites sharper scrutiny from lawmakers already drafting trading bans. The sector's actual compound growth will depend on whether platforms can expand contract menus without triggering the sports-contract crackdown Grous's own research ecosystem is now tracking.
