ARK Invest has added private prediction-market exchange Kalshi to its ETF strategies, Cathie Wood said on September 30, expanding the firm’s exposure to a CFTC-regulated event-contract platform. Wood did not disclose the position size or identify the funds holding Kalshi, although earlier information had specified ARKK, ARKW and ARKF. ARK estimates prediction markets could eventually generate $1 trillion to $5 trillion in annual trading volume. Separately, ARK’s September 29 trade notification showed purchases of NVIDIA, Broadcom, CoreWeave, Tesla and SpaceX across its actively managed ETFs, while AMD was reduced in four funds. Kalshi’s private shares are not included in ARK’s public-equity trade files, which the firm says are unofficial, unreconciled and not comprehensive.
