Nvidia to invest up to $100B in OpenAI, fueling AI dominance — and antitrust worries

Nvidia will invest up to $100 billion in OpenAI and supply it with advanced data center chips, the companies confirmed Monday, marking one of the largest-ever deals in artificial intelligence. The pact ties together the world’s leading AI chipmaker and the sector’s most high-profile model developer, deepening concerns about market concentration.

Deal structure

  • Nvidia will acquire non-voting shares in OpenAI.

  • OpenAI will use the cash to purchase Nvidia chips, creating what analysts called a “circular” arrangement.

  • The two companies signed a letter of intent to deploy at least 10 gigawatts of Nvidia systems — equivalent to powering 8 million U.S. homes.

  • Nvidia will begin deliveries in late 2026 via its new Vera Rubin platform, starting with 1 GW of compute.

  • Initial investment: $10B, with further tranches scaling toward $100B.

OpenAI CEO Sam Altman said: “Compute infrastructure will be the basis for the economy of the future, and we will utilize what we’re building with Nvidia to both create new AI breakthroughs and empower people and businesses with them at scale.”

Market reaction

  • Nvidia shares hit a record intraday high (+4.4%).

  • Oracle gained 6% amid its own collaboration with OpenAI, Microsoft, and SoftBank on the $500B Stargate data center project.

  • Broadcom fell 0.8% on concerns the deal could complicate its custom-chip work with OpenAI.

Industry context

The pact follows:

  • Microsoft’s multibillion-dollar investments in OpenAI since 2019.

  • Nvidia’s $5B investment in Intel and its $6.6B backing of OpenAI in 2024.

  • Ongoing OpenAI efforts to design its own AI chips with Broadcom and TSMC, which reportedly remain unchanged.

Antitrust spotlight

The DOJ and FTC reached an agreement in 2024 enabling potential probes into the roles of Microsoft, Nvidia, and OpenAI in AI. Analysts warn this deal could intensify scrutiny:

  • Andre Barlow, antitrust lawyer: “It could potentially lock in Nvidia’s chip monopoly with OpenAI’s software lead, making it more difficult for rivals like AMD or competing AI labs to scale.”

  • Stacy Rasgon (Bernstein): The structure raises concerns about Nvidia’s investment dollars coming back as chip purchases.

The Trump administration has so far taken a lighter regulatory approach than Biden’s, emphasizing growth over enforcement — though officials say protecting competition in AI infrastructure remains a long-term priority.

Nvidia takes $5B stake in Intel, forging alliance on future AI chips

Nvidia announced a $5 billion investment in Intel, acquiring roughly 4% of the struggling chipmaker and pledging to jointly develop new chips for PCs and data centers. The deal comes just weeks after the U.S. government took an extraordinary 10% stake in Intel to shore up the company amid mounting concerns about its competitiveness.

Intel shares surged 23% on the news, while Nvidia’s stock rose nearly 4%. Nvidia will pay $23.28 per share, slightly below Intel’s prior closing price but above what Washington paid earlier this month. The investment makes Nvidia one of Intel’s largest shareholders and marks a pivotal moment in the U.S. effort to counterbalance Asia’s dominance in chip production.

Under the pact, Intel will supply central processors and advanced packaging for joint products that combine Intel CPUs with Nvidia GPUs, linked by Nvidia’s high-speed proprietary technology. The companies pledged to build “multiple generations” of such products, though Nvidia stopped short of committing to use Intel’s foundries for its own chips—a key issue for Intel’s turnaround.

The partnership could reshape the competitive landscape. Analysts say it poses the most immediate risk to AMD, which competes with Intel in supplying data center CPUs, and a longer-term threat to TSMC, which currently manufactures Nvidia’s flagship processors. Broadcom, whose chip-to-chip interconnect technology underpins many AI systems, may also feel pressure.

“This is a massive game-changer for Intel and effectively resets its position of AI-laggard into a cog in future AI infrastructure,” said Gadjo Sevilla, senior analyst at eMarketer. Some analysts even speculate the deal could be the first step toward an eventual breakup or acquisition of Intel by U.S. chipmakers.

Intel’s new CEO, Lip-Bu Tan, has vowed to streamline operations and build capacity more cautiously, only when demand is clear. Nvidia CEO Jensen Huang emphasized the administration was not directly involved in the partnership but noted Washington would welcome the collaboration.

For Intel, the deal adds to a growing cash reserve after a $2 billion investment from SoftBank and $5.7 billion from the U.S. government. For Nvidia, the alliance gives it a foothold in Intel’s deep enterprise and government networks, while cementing its dominance in AI infrastructure.

Taiwan leverages chip power for diplomacy at Semicon trade show

At this year’s Semicon trade show in Taipei, Taiwan elevated its “chip diplomacy” strategy, using its dominance in the semiconductor industry to strengthen diplomatic ties with both established allies and new partners.

Taiwan’s TSMC, the world’s largest contract chipmaker, sits at the center of global supply chains but Taiwan itself remains diplomatically isolated due to China’s sovereignty claims. To counter this, Taiwan’s foreign ministry co-sponsored a Semicon geopolitics panel for the first time, where Foreign Minister Lin Chia-lung described semiconductors and AI as “strategic resources” and stressed the need for trusted, “non-red” supply chains outside China.

The outreach comes as Taiwan courts “like-minded” democracies in Central and Eastern Europe, where sympathy has grown following Russia’s invasion of Ukraine. Czech Science Minister Marek Zenisek, speaking alongside President Lai Ching-te, highlighted shared democratic values and pitched his country as a supplier for TSMC’s first European fab in Dresden, Germany.

But Semicon also drew less expected guests. Costa Rica, which cut ties with Taiwan in 2007 in favor of China, attended for the first time with a national pavilion. And in another first, a group of 10 African tech entrepreneurs joined, supported by the French-African Foundation. Joelle Itoua Owona, CEO of AfriWell Health in the Republic of Congo, said African governments want to diversify partnerships beyond China, calling Taiwan “an additional friend.”

With 17 country pavilions—the most ever— this year’s Semicon showcased how Taiwan’s chip industry has become a powerful diplomatic tool. Beyond chips and AI, the trade show highlighted Taiwan’s role in building global coalitions at a time of intensifying pressure from Beijing.
