OpenAI Funds Its Own $7 Billion Buyback to Keep Valuation Steady—And Anthropic Is Closing In

OpenAI just did something unusual: it used its own cash—not outside investors—to buy back roughly $7 billion of employee shares at a flat $852 billion valuation . The August 10, 2026 tender offer gives current and former employees liquidity while the company works through a confidential IPO filing submitted in June . But the timing tells a bigger story: rival Anthropic is now worth more ($965 billion), leads in enterprise AI, and could go public as early as October 2026, tightening the window for OpenAI's own market debut.

Why OpenAI Self-Funded the Tender Offer Instead of Using Outside Investors

This buyback breaks with OpenAI's past practice. In October 2025, outside investors including Thrive Capital and SoftBank bought $6.6 billion of employee shares at a roughly $500 billion valuation; an earlier 2024 tender also used external buyers .

Valuation control was the primary motive. By using its own balance sheet, OpenAI kept the price flat at $852 billion—matching the March 2026 primary round—without setting a higher mark that could complicate IPO pricing . Bringing in outside investors at a higher price would have effectively set a new private valuation, creating expectations the company may not want to meet in a public offering .

Cash availability made self-funding feasible: OpenAI had ample cash on hand after its $122 billion March raise, the largest single private fundraising round in history . The self-funded approach also avoids dilution for existing holders and signals management's confidence in the balance sheet .

How the Buyback Fits into OpenAI's Path Toward an IPO

The tender offer is the latest step in a carefully sequenced pre-IPO timeline:

• March 2026 — OpenAI closed a $122 billion primary funding round at an $852 billion post-money valuation, the biggest private raise ever .
• June 8, 2026 — OpenAI filed a confidential S-1 registration statement with the SEC, formally beginning the IPO process. It had not yet set a date, exchange, or price range .
• August 10, 2026 — The $7 billion self-funded employee tender offer closed. The tender had been in the works since the March round and serves as a bridge to give employees liquidity while the company works through SEC review .

IPO timeline implications: Multiple reports suggest the IPO is now expected in 2027, not 2026. The sheer size of the tender offer and the absence of a priced deal indicate a public listing is still months away . Analysts have suggested a potential $1 trillion valuation at IPO .

How Competitive Pressure from Anthropic Is Accelerating Urgency

Anthropic has overtaken OpenAI on several critical fronts in recent months, creating direct urgency for OpenAI to reach public markets.

Valuation surpassed: In May 2026, Anthropic raised $65 billion in a Series H round at a $965 billion valuation—vaulting past OpenAI's $852 billion to become the world's most valuable private AI company . Reuters, the Wall Street Journal, and CNBC all confirmed the milestone .

Enterprise AI lead: By August 2026, Anthropic had overtaken OpenAI in the enterprise AI market, according to a Wall Street Journal analysis. Its coding tool Claude Code now commands 54% of the AI coding market and helped drive its annualized revenue from $1 billion to $47 billion .

IPO timeline pressure: Anthropic is approaching its own IPO as early as October 2026 . If Anthropic lists first and is well-received, it could set the valuation benchmark, attract investor dollars, and capture the "first AI IPO" premium—leaving OpenAI to follow on less favorable terms .

Talent retention: The $7 billion buyback also serves to retain employees who might otherwise be tempted by Anthropic's higher private valuation and IPO upside. Self-funding avoided diluting existing holders and signaled confidence in the balance sheet .

Bottom Line

OpenAI's $7 billion self-funded buyback is a carefully timed liquidity event that keeps the company's valuation frozen at $852 billion while it navigates a confidential IPO filing. But the clock is ticking: Anthropic is now worth $965 billion, leads in enterprise AI, and may go public as soon as October 2026—leaving OpenAI in the unfamiliar position of chasing its rival's trail to the public markets.
