The prediction explicitly gives a 20–30 year horizon: David Friedberg says the index of then-current unicorns could be worth more than the ~$46T market cap of all existing U.S. public companies "in the next 20 or 30 years" from the 2021 episode date.(transcriptforest.com) That puts the evaluation window roughly between 2041 and 2051. As of today (November 30, 2025), only about four years have elapsed since the prediction was made, so we are far short of the earliest evaluation date. There is no way yet to determine whether the private-unicorn index in question will exceed $46T within that future window. Therefore the accuracy of the prediction cannot currently be judged and is inconclusive (too early to tell).
