What's this about?
Anthropic is preparing to go public in October in what would be the largest initial public offering in history, surpassing SpaceX's. Reuters reports the valuation case rests on a forecast of $190–200 billion in revenue by 2028; Fortune and the FT report investors betting on a roughly $2 trillion valuation.
What exactly is an IPO valuation "hinging on" a revenue forecast?
When a private company sells shares to the public for the first time, there's no market price yet — it has to be argued for. The standard argument is a multiple of revenue: investors decide what a dollar of future sales is worth and multiply. A $2 trillion valuation against ~$195 billion of 2028 revenue is roughly 10x forward sales, which is aggressive but not unheard of for fast-growing software. The load-bearing assumption isn't the multiple, it's the forecast: 2028 revenue at that scale requires growth continuing at a rate almost nothing sustains, so the entire valuation is a bet on that specific number.
What's the community saying?
- The forecast is the whole argument, and it's three years out. Commenters focused on the fact that the number being underwritten is a projection, not a result — and that AI revenue forecasts have a short track record of holding.
- It caps a remarkable week of AI dealmaking. Landing alongside Stripe buying OpenRouter for $7B+ and Nvidia pulling back its OpenAI backstop, the market is simultaneously making its largest bets and quietly reducing exposure.
- The Nvidia contrast was noted directly. The same weekend that Anthropic seeks a record valuation, Nvidia sharply cut how much OpenAI data-centre financing it would guarantee — two opposite signals about how much risk the infrastructure layer wants to hold.
