NEW YORK (Reuters) -Bitcoin hovered near its record high on Monday as the world's largest cryptocurrency by market value continued to benefit from strong demand from investors. The rally in bitcoin since the start of the year has been underpinned by flows from institutional investors, friendlier policies of the administration of U.S. President Donald Trump, and increasing connection with global financial systems.  Bitcoin climbed above $125,000 for the first time on Sunday, rising to $125,653.32. It was last up 1.66% to $124,861.70, on course for the second straight session of gains. It is has gained more than 33% this year.  (Reporting by Chibuike Oguh in New York; Editing by Chizu Nomiyama )

By Max A. Cherney SAN FRANCISCO (Reuters) -AMD said on Monday it will supply artificial intelligence chips to OpenAI in a multi-year deal that would bring in tens of billions of dollars in annual revenue and give the ChatGPT creator the option to buy up to roughly 10% of the chipmaker. Shares of AMD surged more than 34% to touch a more than one-year high of $226.71 and added $80 billion to its market capitalization. The latest deal, among a string of investment commitments, is a testament to OpenAI and the broader AI industry's voracious appetite for computing power as companies race toward developing AI technology that meets or exceeds human intelligence. The deal offers OpenAI an opportunity to take a stake in one of Nvidia's most formidable rivals and is a major vote of confidence in AMD's AI chips and software. "We view this deal as certainly transformative, not just for AMD, but for the dynamics of the industry," AMD executive vice president Forrest Norrod told Reuters on Sunday. The agreement covers the deployment of hundreds of thousands of AMD's AI chips, or graphics processing units (GPUs), equivalent to six gigawatts, over several years beginning in the second half of 2026. This is roughly equivalent to the energy needs of 5 million U.S. households, or the electricity produced by the Hoover Dam thrice over. AMD said OpenAI would build a one-gigawatt facility based on its forthcoming MI450 series of chips beginning next year, and that it would begin to recognize revenue then. AMD executives expect the deal to net tens of billions of dollars in annual revenue. Because of the ripple effect of the agreement, AMD expects to receive more than $100 billion in new revenue over four years from OpenAI and other customers, they said. "Other people are going to come along with it because this is really the pioneer, a pioneer in the industry that has a lot of influence over the broader ecosystem," AMD strategy chief Mat Hein said. The deal with AMD will help OpenAI build enough AI infrastructure to meet its needs, OpenAI CEO Sam Altman said in a statement. It was not immediately clear how OpenAI would fund the massive deal with AMD. OpenAI has generated around $4.3 billion in revenue in the first half of 2025 and has burned through $2.5 billion in cash, according to media reports, as the startup splurges on attracting top talent, while investing heavily in developing new AI tools. Analysts, on average, estimate AMD will generate revenue of $32.78 billion this year, according to LSEG data. As part of the arrangement, AMD issued a warrant that gives OpenAI the ability to buy up to 160 million shares of AMD for 1 cent each over the course of the chips deal. The warrant vests in tranches based on milestones that the two companies have agreed on. The first tranche will vest after the initial shipment of MI450 chips set for the second half of 2026. The remaining milestones include specific AMD stock price targets that escalate to $600 a share for the final installment of stock to unlock. OpenAI has a valuation of $500 billion. OPENAI WANTS MORE GPUs OpenAI has worked with AMD for years, providing inputs on the design of older generations of AI chips such as the MI300X. The San Francisco-based AI company has been taking a number of steps to ensure it has the chips needed for its future needs. In September, Nvidia announced an investment of up to $100 billion in OpenAI that included a plan to supply at least 10 gigawatts worth of Nvidia systems. The plan includes OpenAI deploying a gigawatt of Nvidia's next-generation Vera Rubin chips in late 2026. Altman has floated expectations of reaching 250 gigawatts of compute in total by 2033, The Information has reported. In addition to using Nvidia hardware, cloud computing giants such as Alphabet's Google and Amazon build their own in-house processors. Similarly, OpenAI is in the process of developing its own silicon for AI use and has partnered with Broadcom, Reuters reported last year. Shares of Nvidia dipped more than 1%, while those of Broadcom were little changed. OpenAI and its main backer Microsoft also announced last month that they had signed a non-binding agreement to restructure OpenAI into a for-profit entity, signaling further changes in the governance of the fast-growing AI company. A person familiar with the matter said the deal with AMD does not change any of OpenAI's ongoing compute plans, including that effort or its partnership with Microsoft. (Reporting by Max A.

By Akash Sriram (Reuters) -Tesla teased an October 7 event, in which investors and analysts anticipate a more affordable model to sustain sales momentum, sending the shares of the Elon Musk-led electric automaker 3% higher in early trading on Monday. In a nine-second video posted on social media platform X on Sunday, Tesla showed a vehicle with its headlights illuminated in a dark setting, while hinting at an event set for Tuesday in a separate video that had "10/7" at the end. Tesla has previously delayed rolling out a lower-cost version of the Model Y in the U.S. It said in June it had made "first builds" of the vehicle, but would start selling it in the fourth quarter and ramp up output at a pace that would be slower than planned. The stripped-down version is designed to be roughly 20% cheaper to produce than the refreshed Model Y and could scale to about 250,000 units a year in the U.S. by 2026. "Tesla is teasing something big as a flurry of X posts has fans bracing for what looks like the launch of a more affordable Model Y tomorrow," said Matt Britzman, senior equity analyst, Hargreaves Lansdown, who personally owns Tesla shares. "The price tag will be the real tell, offering clues on how far Tesla has pushed cost savings and how much new demand it can unlock." The teaser follows Tesla's record third-quarter deliveries, driven by a surge in EV purchases ahead of the expiration of the $7,500 U.S. EV tax credit on September 30. However, analysts expect sales to drop off in the coming months without the incentive. Wall Street expects Tesla's deliveries to jump next year to 1.85 million vehicles, with the cheaper model accounting for 155,610 units in 2026, according to Visible Alpha estimates. The company has not introduced a new mass-market vehicle in years, relying heavily on incremental updates to the Model 3 and Model Y to drive sales. Sales of its last major launch, the Cybertruck, have struggled, with Tesla offering thousands of dollars in discounts for vehicles in inventory in the past few months. A U.S. recall filing in March showed 46,096 Cybertrucks had been built between its introduction in November 2023 and early this year.

By Dawn Chmielewski and Helen Coster LOS ANGELES (Reuters) -Paramount Skydance CEO David Ellison has named Bari Weiss editor-in-chief of CBS News, as part of a deal to acquire the online news site she founded, The Free Press. The companies did not disclose the deal value in Monday's announcement. A source familiar with the matter said it was for $150 million. In an essay announcing the deal Monday, Weiss, 41, said the deal provides "a chance to help reshape a storied media organization—to help guide CBS News into a future that honors those great values that underpin The Free Press and the best of American journalism." The announcement capped months of talks between Ellison and Weiss. The newly minted media baron first floated the idea at July's Allen & Co conference in Sun Valley, a frequent staging ground for major media mergers, according to media reports. Weiss resigned as an opinion writer for the New York Times in July 2020, in a 1,500-word open letter in which she described being the subject of "constant bullying" by colleagues who disagreed with her views.  In 2022, she founded her new media company on a credo of "honesty, doggedness, and fierce independence." "This move is part of Paramount's bigger vision to modernize content and the way it connects – directly and passionately – to audiences around the world," Ellison said, calling Weiss "a proven champion of independent, principled journalism." In a letter to CBS News employees, Weiss said that CBS was part of her family tradition. "Whenever I hear that tick, tick, tick or that trumpet fanfare, it sends me right back to our den in Pittsburgh,"  Weiss wrote in the letter seen by Reuters. "The opportunity to build on that legacy with you — and to renew it in an era that so desperately needs it — is an extraordinary privilege." Weiss said she wanted to hear from the staff at CBS News about what's working and what's not, with the goal of making CBS News the most-trusted news organization in America. She promised to listen with "an open mind, a fresh notebook and an urgent deadline." The Free Press has earned a reputation for challenging conventional narratives. Notable articles include a first-person essay from a then-senior editor at NPR, who accused the public radio network of liberal bias that cost it listeners' trust.  Another offered a whistleblower account of the Washington University Transgender Center at the St. Louis Children's Hospital, which reported vulnerable teenagers with mental health problems rushed into life-altering treatments. Weiss will report directly to David Ellison, and help set an editorial course for CBS News. The network's evening news broadcast is in third place behind its television peers. She will work with CBS News President Tom Cibrowski, who joined in 2025 after spending 25 years at ABC News in a variety of leadership positions. Cibrowski will continue to report to George Cheeks, Paramount's chair of TV Media. The Free Press, which has about 1.5 million subscribers including 170,000 paying members, will remain independent, retaining its brand and operations, the companies said. The Free Press will continue to publish. Major media and tech companies are now controlled by supporters of President Donald Trump or billionaire business leaders who lined up behind him during his inauguration, donated to his inaugural fund or visited the White House with gifts. The son of longtime Trump supporter Larry Ellison, David Ellison, helped secure regulatory approval for his company Skydance Media to buy Paramount, with the promise that the CBS network would reflect "a diversity of viewpoints from across the political and ideological spectrum," according to a statement from Federal Communications Commission Chairman Brendan Carr announcing the deal. Prior to the deal, Paramount paid $16 million to settle a 2024 lawsuit Trump filed over a "60 Minutes" interview with former Vice President Kamala Harris, which he claimed gave a distorted view of his rival for the White House. The FCC has said the settlement and regulatory review were unrelated. In early September, the company announced the appointment of its new ombudsman, Kenneth Weinstein, a former president and CEO of the conservative Hudson Institute.     (Reporting by Dawn Chmielewski in Los Angeles and Helen Coster in New York, Aditya Soni and Jaspreet Singh in Bengaluru; Editing by Sriraj Kalluvila and Nick Zieminski)

(Reuters) -Nvidia is set to invest up to $100 billion in OpenAI and supply it with data center chips, in a deal that gives the chipmaker a financial stake in the world's most prominent AI company, which is already an important customer. Investments in systems powering AI have surged since OpenAI launched ChatGPT in 2022, on expectations that companies across sectors will integrate the technology into their products and services. Here is a list of multi-billion dollar AI, cloud and chip deals signed recently: Nvidia and Intel Nvidia will invest $5 billion in Intel, giving it roughly 4% of the company after new shares are issued. Oracle and Meta Oracle is in talks with Meta for a multi-year cloud computing deal worth about $20 billion, underscoring the social media giant's drive to secure faster access to computing power. Oracle and OpenAI Oracle is reported to have signed one of the biggest cloud deals ever with OpenAI, under which the ChatGPT maker is expected to buy $300 billion in computing power from the company for about five years. CoreWeave and Nvidia CoreWeave signed a $6.3 billion initial order with backer Nvidia, a deal that guarantees that the AI chipmaker will purchase any cloud capacity not sold to customers. Nebius Group and Microsoft Nebius Group will provide Microsoft with GPU infrastructure capacity in a deal worth $17.4 billion over a five-year term. Meta and Google Google struck a six-year cloud computing deal with Meta Platforms worth more than $10 billion, Reuters had reported in August. Intel and SoftBank Group Intel is getting a $2 billion capital injection from SoftBank Group, making the Japanese tech investor one of the top-10 shareholders of the troubled U.S. chipmaker. Tesla and Samsung Tesla signed a $16.5 billion deal to source chips from Samsung Electronics, with the EV maker's CEO Elon Musk, saying that the South Korean tech giant's new chip factory in Texas would make Tesla's next-generation AI6 chip. Meta And Scale AI Meta took a 49% stake for about $14.3 billion in Scale AI and brought in its 28-year-old CEO, Alexandr Wang, to play a prominent role in the tech giant's artificial intelligence strategy. Google and Windsurf Google hired several key staff members from AI code generation startup Windsurf and will pay $2.4 billion in license fees as part of the deal to use some of Windsurf's technology under non-exclusive terms. CoreWeave and OpenAI CoreWeave signed a five-year contract worth $11.9 billion with OpenAI in March, before the Nvidia-backed startup's IPO. Stargate datacenter project Stargate is a joint venture between SoftBank, OpenAI and Oracle to build data centers. The project was announced in January by U.S. President Donald Trump, who said that the companies would invest up to $500 billion to fund infrastructure for artificial intelligence. Amazon and Anthropic Amazon.com pumped $4 billion into OpenAI competitor Anthropic, doubling its investment in the firm known for its GenAI chatbot Claude.

(Reuters) -Verizon Communications on Monday named former PayPal boss Dan Schulman as its new CEO, replacing Hans Vestberg in a leadership transition aimed at steering the telecom giant through slowing growth in the wireless market. The move comes at a time when Verizon is battling rising competition against the backdrop of slowing subscriber growth and cautious consumers unwilling to buy premium plans offered by wireless carriers. Vestberg, who took the helm in 2018, will remain with the company as a special adviser through October 4, 2026, Verizon said. Schulman, 67, led PayPal for nearly a decade before stepping down in 2023, steering the payments firm through its split from eBay and a surge in online transactions during the COVID-19 pandemic. Vestberg's tenure at Verizon was marked by heavy investments in 5G networks and efforts to diversify revenue through media and enterprise services, though the company later exited most of its media holdings. Verizon has faced mounting pressure from rivals AT&T and T-Mobile US as the U.S. wireless market matures. Verizon's stock has underperformed shares of rival telecom operators in the past few years. The appointment comes a few weeks after competitor T-Mobile announced a CEO replacement, reflecting a changing U.S. telecom sector with market leaders working to attract consumer dollars amid fierce competition.

(Reuters) -Algen Biotechnologies said on Monday it has agreed to grant AstraZeneca a license to develop gene therapies the U.S.-based biotech discovers using its artificial intelligence-driven platform, in a deal worth up to $555 million. Under the deal, AstraZeneca will get exclusive rights to develop therapies that target immune system-related disorders. The Anglo-Swedish pharmaceutical major will also get the right to sell the treatments, if they get approved, while Algen will get upfront and milestone payments. AstraZeneca has been advancing its cell and gene therapy capabilities through acquisitions and partnerships as it works towards its target of $80 billion in sales by 2030. Globally too, drugmakers are increasingly turning to AI for drug development. The drugmaker in March agreed to buy Belgian biotech EsoBiotec for up to $1 billion, gaining access to technology that modifies immune cells directly inside the body. Monday's deal, however, does not include AstraZeneca buying a stake in the company, Algen CEO and co-founder Chun-Hao Huang told Reuters in an interview. "Together with AstraZeneca's deep expertise in translational science and clinical development, we aim to uncover new biological insights to accelerate the development of novel therapies," Huang said. Algen was spun out from the lab at UC Berkeley, where biochemist Jennifer Doudna pioneered the CRISPR technology that won her the Nobel Prize. The biotech firm's AI platform, AlgenBrain, can map genes to disease outcomes, helping the companies decide their development focus for therapies. The Financial Times had first reported the news.
