A large, late-stage private funding round, like Anthropic's just before filing to go public, serves a strategic purpose beyond capital. It establishes a valuation floor with sophisticated investors, de-risks the IPO process, and helps build the order book by giving crossover funds a discounted entry point.

Anthropic may leapfrog OpenAI in valuation due to factors beyond technology. Investors are betting on its stable leadership and lack of public controversy, which has made it highly successful in recruiting senior executives from major tech companies.

SpaceX's IPO was a textbook success, raising $75B and trading up 25%. It pioneered strategies for pricing, liquidity, early S&P 500 inclusion, and lockups, creating a clear playbook for the upcoming mega-IPOs from Anthropic and OpenAI.

Following the two-tiered model of companies like Novo Nordisk, AI safety startup Anthropic established a 'Long-Term Benefit Trust.' This perpetual purpose trust has outside trustees who can appoint directors to the main board, ensuring the company remains aligned with its core mission.

Anthropic is granting founders super-voting shares to retain control post-IPO, a common tech practice. However, for a company building potentially society-altering AI, this move sparks concern as it concentrates power and reduces shareholder oversight over a technology with immense public implications.

Implementing an incorruptible structure doesn't have to happen on day one. Founders can start with a simpler foundation, like a Public Benefit Corp, and then add more complex elements like a Mission Lock Vehicle (as Anthropic did in its Series C) as the company matures and the stakes get higher.

To protect its 'safety first' mission from investor pressure, AI company Anthropic created a 'Long-Term Benefit Trust.' This separate body, staffed by mission-aligned trustees, has the legal power to appoint board members to the for-profit entity, creating a structural guardrail against mission drift.

Anthropic's S-1 filing, coupled with IPO rumors for SpaceX and OpenAI, indicates a strategic rush among tech's most valuable private firms to access public funds. This is likely driven by the immense capital required for AI development and a desire to capture investor enthusiasm first.

To ensure long-term ethical decision-making, founders can embed it into their corporate governance from day one. Following Anthropic's model, they can create an ethics committee and mandate that some board seats are filled by people who hold no shares, creating an incorruptible check on purely profit-driven decisions.
