Public Investors Missed the AI Growth, Baillie Gifford’s Singlehurst Says

What Happened

SpaceX, Anthropic, and OpenAI are among the high-valuation companies expected to go public in the coming months. But Peter Singlehurst, head of the private companies team at Baillie Gifford, says public market investors have already missed out on a lot of growth. He joins Caroline Hyde and Ed Ludlow

Our Take

OpenAI, Anthropic, and SpaceX are approaching public markets, but Baillie Gifford's Peter Singlehurst is stating plainly: the compounding growth phase already happened in private rounds.

This matters for AI infrastructure decisions now. Teams treating Anthropic's API pricing as stable are building on a company that may face public-market margin pressure post-IPO. Claude 3.5 Sonnet at $3/MTok input could look very different in 18 months. Assuming frontier model costs stay predictable is a planning mistake.

If you're architecting a multi-year RAG or agent pipeline, price your models at 2x current cost in your unit economics today. Lock multi-year enterprise agreements before IPO pressure hits margins.

What To Do

Do multi-year API contract negotiation now instead of month-to-month billing because post-IPO margin pressure on Anthropic and OpenAI will likely push enterprise pricing up.

What Skeptics Say

Baillie Gifford holds significant pre-IPO stakes in Anthropic, OpenAI, and SpaceX, making 'public investors missed it' a self-serving narrative that frames elevated private valuations as validated rather than as a liquidity risk for retail markets on the other side of the IPO.
