OpenAI's chief revenue officer sent an internal memo claiming Anthropic overstates its headline $30B run rate by roughly $8B — a direct challenge to the accounting narrative anchoring Anthropic's $600B secondary valuation. Separately, $600M in OpenAI shares sit unsold on secondary platforms while $2B in buy-side demand chases Anthropic stock with zero sellers. Underneath all of it, SpaceX's public S-1 is weeks away — and it reshapes the IPO window for every company standing behind it.
