Cathie Wood’s ARK Innovation ETF (ARKK) has reached new multi-year highs as it expands into private companies. Recent additions include OpenAI and prediction market Kalshi, marking a shift toward investing beyond public markets.

Private companies now account for more than 3% of the ETF’s assets. ARKK has regulatory approval to increase that allocation to as much as 15%.

The strategy gives the fund access to disruptive companies earlier in their lifecycle and expands its investment universe beyond public markets.
