Sam Altman just said the quiet part out loud. The OpenAI CEO suggested the company could be less than six months away from achieving recursive self-improvement, a capability where AI systems can meaningfully enhance their own development, and that hitting this milestone could push back the company’s highly anticipated IPO.
For a company valued at roughly $852B in its latest funding round, the idea of voluntarily pumping the brakes on a public offering is, well, noteworthy.
What recursive self-improvement actually means
Think of recursive self-improvement like compound interest, but for intelligence. Instead of humans writing code to make AI better, the AI starts writing code to make itself better. Then that improved version makes an even better version. And so on.
Altman has previously described current AI progress as a “larval version of recursive self-improvement.” Earlier in 2025, he went further, stating that humanity had surpassed the “event horizon” for AI self-improvement.
OpenAI has laid out internal milestones: automated intern-level functionality expected by September 2026, with a full “automated AI researcher” capability targeted for March 2028.
Competitors are seeing similar acceleration. Anthropic recently reported that AI task horizons are doubling every four months. The company also noted that its engineers are now producing eight times more code per quarter than they were previously.
The IPO that might not happen on schedule
OpenAI has been planning to file for a confidential IPO as soon as September 2026. At an $852B valuation, this would be one of the largest public offerings in history.
Internal perspectives at OpenAI apparently vary on timing. Some voices within the company already favored a later timeline for the IPO before Altman’s RSI comments added another variable to the equation.
What this means for investors
For investors already holding OpenAI equity through secondary markets or its various funding rounds, a delay isn’t necessarily bad news. If RSI materializes, the company’s valuation could increase substantially before shares hit public markets. The $852B figure could look quaint in retrospect.
There’s also been speculation about OpenAI exploring alternative financing methods, including the possibility of a crypto token. While nothing concrete has materialized on that front, the mere existence of such discussions signals that the company is thinking creatively about capital structure.
Anthropic’s data showing task horizons doubling every four months suggests this isn’t just an OpenAI story. Any company that achieves genuine RSI first gains a significant advantage, because the technology literally improves itself faster than competitors can catch up manually.
