AMD Stock’s 2025 Surge: How a Landmark Partnership With OpenAI Reshaped the AI‑Chip Race

In early October 2025 the tech sector experienced one of its biggest shocks of the year.

Advanced Micro Devices (AMD) announced a multi‑year partnership with OpenAI that will see the ChatGPT developer deploy 6 gigawatts (GW) of AMD Instinct GPUs over five years.

A warrant issued to OpenAI also gives it the right to buy up to 160 million AMD shares at $0.01 per share, potentially a ~10 % stake if milestones are met.

OpenAI’s commitment begins with a 1 GW deployment of next‑generation MI450 GPUs in the second half of 2026.

The deal aligns product roadmaps and deepens the collaboration that started with AMD’s MI300 and MI350 series.

It was valued at tens of billions of dollars in annual revenue for AMD.

A Record‑Setting Jump in AMD’s Share Price

Pre‑market surge

The announcement sent AMD’s stock price soaring.

Analysts tracking the stock via financial‑market platforms noted that shares jumped 27 % in pre‑market trading to about $210.

The surge followed OpenAI’s disclosure of a $10 billion AI‑chip deal with AMD that investors interpreted as a validation of AMD’s AI strategy.

Economic Times commented that the market excitement came from the potential to challenge Nvidia’s dominance and predicted that AMD’s stock could begin October near $164, reach $193 at the month’s high and close near $179, implying a 9 % gain.

Tech media outlets also reported rapid gains; TechCrunch and Reuters said AMD’s stock jumped more than 34 % to around $215—the stock’s biggest one‑day percentage gain since 2016—after the news was released.

Reaction of the broader market

• Nasdaq analysis: A pre‑market report from Nasdaq noted that AMD shares were soaring 35.7 % after the announcement.
• Dataconomy: The tech publication Dataconomy highlighted that investors following AMD on Yahoo Finance saw a significant pre‑market jump and that the partnership was expected to generate tens of billions of dollars in revenue.
• The Verge: The Verge reported that AMD’s stock price was up 24 % in pre‑market trading on the day of the announcement.

Although the reported percentages differed slightly, there was consensus that AMD’s stock rocketed more than 25 % before markets opened. The stock closed the day above $200, adding tens of billions of dollars to AMD’s market capitalization.

What the Partnership Means

Details of the AMD–OpenAI agreement

• Six‑gigawatt compute capacity: OpenAI will deploy 6 GW of AMD Instinct GPUs over five years. The first gigawatt, using MI450 GPUs, will be delivered in the second half of 2026.
• Warrant for AMD shares: AMD granted OpenAI a warrant for up to 160 million shares at one cent per share, roughly 10 % of AMD’s equity. The warrant vests in tranches tied to deployment milestones and AMD’s share‑price targets; final tranches require AMD stock to reach $600.
• Revenue potential: AMD’s CEO Lisa Su expects the partnership to deliver tens of billions of dollars in revenue and be highly accretive to earnings per share.
• Collaborative roadmaps: The deal builds on cooperation begun with AMD’s MI300 and MI350 series GPUs and will let AMD and OpenAI co‑optimize hardware and software roadmaps. Sam Altman said the partnership would accelerate AI progress by enabling enormous computing capacity.

Why OpenAI chose AMD

• Diversification from Nvidia: OpenAI previously signed a letter of intent with Nvidia to deploy 10 GW of Nvidia GPUs and invest up to $100 billion. However, supply constraints and Nvidia’s market dominance have prompted AI companies to diversify. Reuters noted that AMD’s agreement ties OpenAI to a rival chipmaker and is seen as a major vote of confidence in AMD’s AI chips.
• MI350 and MI450 advancements: AMD’s latest MI350 series GPUs deliver up to 4× the performance of the previous MI300X platform and allow models with 520 billion parameters to run on a single GPU. The upcoming MI450 is expected to feature 432 GB of HBM4 memory and deliver ~40 PFLOPS of FP4 compute, surpassing AMD’s MI355X and challenging Nvidia’s upcoming Vera Rubin chips (288 GB HBM4 and 50 PFLOPS).
• Commitment to AI leadership: Forrest Norrod, AMD’s data‑center chief, described the MI450 launch as AMD’s “Milan moment”—referring to the 2021 EPYC Milan CPUs that broke Intel’s dominance. He said MI450 is planned to be the best training, inference and reinforcement‑learning solution on the market.

Impact on Nvidia and AI‑Chip Competition

Immediate market reaction

The AMD–OpenAI announcement rattled Nvidia’s stock. PhoneArena reported that Nvidia shares dropped as much as $4.39 (2.3 %) to $183.33 on the morning of the announcement, while AMD shares jumped $45.45 (27.6 %) to $210.12.

As trading progressed, Nvidia’s stock rebounded; by 11:30 a.m. ET it was down only $1.51 (0.81 %). Analysts remained broadly bullish on Nvidia, with 60 out of 66 tracked by FactSet still rating the stock a “Buy”.

AI‑chip arms race

While Nvidia remains the dominant supplier, controlling an estimated 70–95 % of the AI accelerator market, AMD’s MI355X and upcoming MI450 show significant progress:

• MI355X vs. Blackwell: AMD’s MI355X platform offers up to 4.2× higher inference performance and comparable or faster training versus the MI300X, and includes 288 GB HBM3E memory to support models with more than 520 billion parameters.
• MI450 vs. Vera Rubin: The MI450’s 432 GB HBM4 and 40 PFLOPS performance is competitive with Nvidia’s Vera Rubin (288 GB HBM4 and 50 PFLOPS). The MI450 is slated to launch in 2026, around the same time as Rubin, setting up a direct performance showdown.

AMD’s strategy is to align its MI450 release with Nvidia’s Rubin and deliver a full software stack so that customers will not need to compromise on training performance. Norrod acknowledged Nvidia’s head start but said AMD’s multi‑generational roadmap aims to achieve parity or leadership by the MI450 generation.

Wider industry implications

The AMD–OpenAI deal is part of a broader AI infrastructure spending spree. HPCwire noted that the AI boom has prompted cloud giants like Meta, Google, Microsoft and OpenAI to build hundreds of data centers, spending trillions of dollars. Nvidia’s revenues have increased nearly seven‑fold over four years to $130.5 billion for fiscal 2025, making it the world’s most valuable company.

AMD’s partnership provides OpenAI with an alternative supplier and underscores the voracious demand for computing power. Analysts interviewed by Fortune and Reuters agreed that the deal will not immediately dent Nvidia’s dominance, but it signals growing competition and could expand overall capacity.

What About “OpenAI Stock”?

Several search terms related to “OpenAI stock” trended after the announcement. However, OpenAI remains a privately held capped‑profit company. There is no publicly traded OpenAI stock. The only way for investors to gain exposure to OpenAI’s growth is through its partners.

In September 2025, Microsoft and OpenAI signed a non‑binding agreement that would allow OpenAI to restructure itself into a for‑profit company and eventually go public. The arrangement would convert OpenAI’s for‑profit arm into a more conventional public benefit corporation and pave the way for an initial public offering (IPO). Details of the restructuring are still being negotiated.

Until such a restructuring occurs, the AMD warrant offers OpenAI an indirect stake in a public company. By granting OpenAI up to 160 million AMD shares, the agreement ties OpenAI’s financial upside to AMD’s success. As Dataconomy noted, the absence of a tradable OpenAI stock makes AMD shares a proxy for investors looking to participate in OpenAI’s growth.

Takeaway: A Turning Point for AI Chips

The AMD–OpenAI partnership is more than a supply contract—it’s a strategic alignment that could reshape competition in AI hardware.

It gives OpenAI guaranteed access to massive amounts of compute, reduces its dependence on Nvidia, and positions AMD as a credible alternative. Investors responded by propelling AMD’s stock to record highs, with pre‑market gains reported between 24 % and 35.7 %, while Nvidia’s shares dipped before recovering.

Longer term, the success of the deal will depend on AMD meeting its deployment milestones, delivering MI450 on time, and continuing to improve its ROCm software ecosystem so that AI developers can easily migrate from Nvidia.

With the AI‑chip market expected to grow exponentially and major tech companies investing in multi‑gigawatt data centers, AMD’s partnership with OpenAI may mark a turning point—both for the company’s stock and for the competitive landscape of AI hardware.
