Tenstorrent Closes $1.5 Billion Series E Funding and Challenges NVIDIA

Chip developer Tenstorrent completed a Series E funding round of $1.5 billion on October 19, 2026, reaching a valuation of $6.2 billion. As the company announced on October 20, 2026, stablecoin issuer Tether participated in the round. Tether is considered a major gold investor and is the issuer of USDT, the largest stablecoin by market capitalisation.

Tenstorrent Remains Independent

Despite investor interest, Tenstorrent plans to continue operating as an independent company. The company is thus entering into direct competition with NVIDIA, which dominates the AI chip market. The funding round underscores the growing importance of capital in the competition for market share in the AI chip industry.

Capital as a Key Competitive Factor

Competition in the AI chip market is increasingly shifting from technological capabilities to capital availability. According to Fortune, the race is shifting from pure chip performance and data center capacity to access to financing sources. The ability to mobilise large amounts of capital is increasingly determining companies' competitiveness.

The five largest US hyperscalers are expected to spend $730 billion on capital expenditures in 2026, with up to one-third financed through debt. Even the world's most profitable companies require external financing to maintain their competitive position.

Other NVIDIA Competitors Secure Capital

In addition to Tenstorrent, other competitors raised substantial sums in 2026. Cerebras Systems received $1 billion in funding in February 2026. Groq LLC announced a Series A round of $350 million on August 17, 2026, reaching a valuation of $3.5 billion. The round was led by Disruptive, with NVIDIA itself planning to participate. Groq raised approximately $1 billion in total in June and August 2026.

Transatlantic Financing Gap

The financing landscape shows clear geographic differences. By April 2026, European AI chip startups had raised only $800 million, while US companies received $4.7 billion in the same period. For China and Europe, closing the technological gap partly depends on whether they can also close the corresponding financing gap.

NVIDIA's Financing Offensive

NVIDIA is responding to the capital-intensive nature of AI infrastructure with its own financing strategy. In August 2026, the company announced partnerships with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR to create independent platforms for financing compute infrastructure. The goal is to mobilise more than $500 billion in capital from third parties.

The approach attempts to establish computing power as an asset class, comparable to traditional infrastructure such as power plants or toll roads. This is intended to make the technology accessible to pension funds and insurance companies as a long-term investment. However, this model carries risks: graphics processors have a shorter lifespan than classic infrastructure investments, demand for AI performance remains difficult to predict, and return projections are speculative.

Institutional Investors Step In

The participation of institutional investors such as Goldman Sachs, BlackRock, Blackstone, KKR and Apollo signals that financial markets recognise AI infrastructure as a distinct investment class. The involvement of alternative investors like Tether in Tenstorrent's funding demonstrates a diversification of financing sources beyond traditional venture capital.

NVIDIA nevertheless retains competitive advantages through established relationships with the largest buyers of AI infrastructure. Competitors such as Intel and AMD face an increasingly crowded competitive environment, while new market entrants are striving for independence despite investor interest.
