Nvidia (NVDA) and SoftBank (9984 JT) have both made the final USD 10bln investment in each of their USD 30bln pledges to OpenAI’s last funding round, The Information reports, citing sources

This is the completion of an already-announced commitment rather than new capital, so the incremental read is limited; what it confirms is that the largest strategic backers of the leading private AI lab have followed through on their pledges in full, a step that in past mega-rounds has occasionally been renegotiated or tranched when conditions shifted. The structurally notable feature is the circularity: a chip supplier funding its own largest end customer, a pattern that has precedent in prior technology cycles where vendor financing sustained demand for the supplier's own products and later drew scrutiny over revenue quality. For the chipmaker, the tell is how such investments are characterised in filings and whether disclosure around related-party exposure expands. For the Japanese conglomerate, concentrated bets of this size on a single asset fit its established form, and past episodes of that kind have amplified both its earnings swings and its sensitivity to the valuation of one holding. Worth watching is any signal of a subsequent round at a revised valuation, since completion of the prior commitments typically clears the way for the next raise and resets the private mark against which listed comparables trade.
