TSMC’s board authorized investments of up to $500 million each in Anthropic and OpenAI on November 10, 2026, setting a combined ceiling of $1 billion. The authorization specifies common shares in Anthropic at its per-share IPO price and preferred stock in OpenAI, according to TSMC’s board resolution.
The $1 billion figure is the combined maximum authorized for the two investments.
How the two company allocations differ
| Company | Maximum authorized | Security and terms |
| Anthropic, PBC | Up to $500 million | Common shares at Anthropic’s per-share IPO price |
| OpenAI Group PBC | Up to $500 million | Preferred stock |
The amounts are authorization limits, not a reported total spent. The resolution ties TSMC’s Anthropic allocation to the company’s IPO price per share; it gives no corresponding per-share price for OpenAI’s preferred stock.
For broader context on Anthropic’s potential IPO valuation, see NeoTeo’s earlier coverage. That topic is separate from the terms of TSMC’s board authorization.
A separate authorization for semiconductor investments
TSMC’s board also authorized up to $500 million to establish an investment company for strategic investments in the semiconductor industry and its related ecosystem. That is a separate authorization from the two company-specific allocations, so it is not part of their combined $1 billion ceiling.
