The Real Novelty Is Tax-Paid-in-Stock, Not Cash
What separates Sanders' proposal from a conventional windfall tax is the payment instrument. Rather than collecting cash, the bill imposes a one-time 50% tax that AI companies satisfy by handing over shares, depositing that equity directly into a public sovereign wealth fund [1]. The mechanism sidesteps the obvious objection that frontier labs are cash-poor: OpenAI and Anthropic remain unprofitable, so a cash levy would be hard to pay [2]. Paying in stock instead converts paper valuations into public ownership without touching operating cash.
It also reshapes the relationship from taxpayer-and-treasury to shareholder-and-company: the fund's 7-member Independent Commission for Democratic AI would wield voting shares to block harmful corporate decisions, and mixed companies would have to carve their AI divisions away from non-AI businesses so the public stake attaches only to AI operations [1]. That is governance leverage, not just revenue.
