The AI industry’s most profitable “shovel sellers” are now also funding the most capital-intensive “gold miners.” According to Nikkei, TSMC plans to invest up to $1 billion combined in OpenAI and Anthropic. TSMC’s board has already approved the move: $500 million will be used to purchase preferred shares in OpenAI, and another $500 million will be allocated to buy common shares in Anthropic at the IPO price. Notably, TSMC did not bet on just one model company—it invested in both of the industry’s largest competitors. The significance of this investment goes far beyond the $1 billion. In the past, TSMC was a relatively certain winner in the AI supply chain. No matter which model company ultimately prevailed, advanced AI chips designed by NVIDIA, AMD, and other tech firms all depended on TSMC’s manufacturing capabilities. Now, this upstream player, controlling scarce production capacity, is directly taking equity stakes in downstream model companies. The AI industry is forming an increasingly tight capital loop: model companies raise funds to buy compute power; chip suppliers earn revenue from these sales; and then reinvest those earnings back into the model companies. While this relationship strengthens industry collaboration, it also raises a subtle question: when chip manufacturers become shareholders in model companies, could capital ties further influence capacity allocation? And how much of this continuous cycle of investment will ultimately translate into real commercial demand? In the past, shovel sellers didn’t need to care who found the gold. Now, they want a share of the mine itself.
