Ark Invest CEO Cathie Wood praised Kalshi’s management team as the prediction-market platform positions itself for industry growth. Her comments followed the Sept. 18 purchase of 126,594 Kalshi shares across three actively managed ARK ETFs, bought directly from private markets. ARK analyst Nick Grous estimates the medium-term prediction-market opportunity at $1 trillion to $5 trillion in annual notional volume, with Kalshi handling more than 90% of U.S. activity. ARK identified legal challenges, competition from Robinhood and potential pressure on take rates as risks, but said it believes the opportunity outweighs them. The article also detailed the funds’ assets, fees, performance and ARKK’s latest price action.
