OpenAI weighs a funding round at a USD 1.2tln valuation before IPO, according to FT

In past episodes of this kind, the pre-IPO round has tended to act as a soft floor and a sentiment gauge, with the eventual listing priced either above it on strong momentum or below it when private marks proved generous. The step-up in headline valuation from prior rounds is the tell for whether private capital is still chasing AI exposure at accelerating terms or whether discipline is creeping in. For listed markets the transmission runs through the named strategic backer and the wider AI-linked complex, where comparable rounds have historically lifted the peer set on read-across rather than on any direct earnings channel. Worth noting that the report is attributed to a single press source and describes a round being weighed rather than agreed, so terms, size and timing all remain fluid. The follow-ons are confirmation of lead investors, any secondary component letting staff sell, and signals on IPO timing, since the gap between this round and a filing is where valuation risk concentrates.
