Can I transfer an investment to a hedge fund from my IBKR account?

Yes.

If a fund accepted you as an investor, IBKR can transfer the investment directly from your IBKR account to the fund’s account (with the approval of the fund and its third-party administrator, and in accordance with your and the fund’s instructions). IBKR will process transfers of $25,000 or greater. Funds may set their own minimum investment requirements.
