Anthropic: the tender nobody fully showed up for

The situation

Anthropic followed OpenAI's large October 2025 tender with its own employee liquidity offer in April 2026, targeting $5-6 billion in sales at a $350 billion pre-money valuation. Most tender offers are described in terms of oversubscription — more sellers than the pool can absorb, as with the proration that's typical when a tender is popular. Anthropic's went the other way.

How the deal worked

Employee participation came in below the company's target. Reporting on the shortfall was explicit that this wasn't a pricing objection in the usual sense — employees weren't unhappy the $350 billion valuation was too low relative to fundamentals. Instead, many chose to simply hold their shares rather than sell, betting the stock would be worth meaningfully more later. Secondary-market pricing observed separately at the time suggested valuations in the $500-800 billion range — well above the tender's $350 billion reference point.

The outcome

Anthropic completed the tender, but with employees holding onto shares rather than participating at the rate the company may have expected. Employees who sat out preserved full upside exposure if the higher secondary-market valuations prove out — at the cost of remaining fully illiquid in the meantime.

What it teaches

A tender offer's price is a company-set reference point, not a market-clearing price — and when employees have visibility into secondary-market chatter suggesting a materially higher valuation, participation can fall even at a price most outside observers would call generous. It's a reminder that discount and premium dynamics run in both directions: sometimes it's the seller, not the buyer, who thinks the price is wrong.
