OpenAI Weighs $1.2 Trillion Pre-IPO Round
Sam Altman is reportedly discussing a new round of venture capital funding that would value OpenAI at $1.2 trillion, according to reports published on September 16, 2026. This move suggests the company may be delaying its planned IPO to secure additional capital from private investors at a higher valuation than previously anticipated. The potential raise underscores the immense scale of capital required for frontier model training and infrastructure, even as public market conditions remain uncertain for tech giants.
CADDi Raises $114M at $1.2B Valuation
On September 15, 2026, manufacturing AI startup CADDi announced a $114 million funding round, achieving a valuation of $1.2 billion. The company aims to address "the physical bottleneck" limiting AI's impact on manufacturing supply chains. This Series D round demonstrates that investors are increasingly willing to assign unicorn status to vertical AI companies that solve specific, high-value operational problems rather than just general-purpose model developers.
Anthropic Secondary Market Price Hits $1 Trillion
Despite a recent employee tender offer priced at a $350 billion valuation, secondary market data from Forge indicates Anthropic’s implied valuation has surged to approximately $1 trillion. This gap highlights a disconnect between company-set liquidity events and market-driven price discovery for top-tier AI labs. The divergence suggests strong demand for exposure to Anthropic ahead of any potential public listing, with investors willing to pay a significant premium over the last internal share sale price.
VC Funding Clusters Around Scarce Inputs
Venture capital activity on September 16, 2026, showed a trend toward clustering around businesses controlling scarce inputs or removing expensive operational bottlenecks, with involvement from Andreessen Horowitz, Index Ventures, and Vista Equity. Investors are increasingly underwriting tangible economic outcomes rather than broad AI adoption curves, signaling a maturation of the investment thesis beyond pure technology hype. This shift favors startups with clear paths to monetization and defensible moats in specific industries.
Local view
In China, local media outlets such as Sina News reported on a "pressure test week" for domestic large model companies, including DeepSeek, Moonshot AI (Kimi), and Zhipu AI. Between September 9 and 13, DeepSeek adjusted its API pricing while retaining its V4 Pro interface, and Moonshot AI denied rumors regarding its financial status, illustrating the intense competitive and regulatory scrutiny facing Chinese AI firms. These developments suggest that while valuations remain high, operational pressures and market skepticism are testing the resilience of the "AI Five Tigers."
Context & numbers
The broader market context remains dominated by the massive capital inflows seen earlier in 2026. In Q1 2026, global venture funding reached roughly $300 billion, with AI capturing approximately 80% of that total ($242 billion). This unprecedented concentration has led to median EV/Revenue multiples for AI companies reaching 25-30x, although M&A deals typically transact at lower multiples. Analysts are now warning of a potential "shakeout" in early-stage AI as venture capital money becomes pickier about valuations and focuses more on productivity metrics.
On the radar
- OpenAI IPO Timeline: Watch for official confirmation or denial regarding the delay of OpenAI's IPO as they pursue the $1.2 trillion private round.
- Secondary Market Volatility: Monitor Forge prices for Anthropic and OpenAI to see if the premium over tender offers sustains or corrects.
- Regulatory Pressure: Increased scrutiny on Chinese AI firms' pricing and data compliance may impact their ability to raise further international capital.
