America's hottest stock in 2025 is barely on anyone's radar
The best-performing stock this year isn't one of the tech giants that dominate headlines. While the likes of Meta, Alphabet, and Amazon have delivered solid gains, they've all been outshone by AI-powered software and data firm Palantir. Palantir's stock has surged 565 percent over the past year — more than doubling in 2025 alone — making it the top performer on the S&P 500. On Monday, the company reported quarterly revenue of $1 billion for the first time, beating Wall Street expectations and sending the stock up another four percent. Best known for building software used by the military, intelligence agencies, and law enforcement, Palantir has seen a sharp uptick in business under President Trump's second term. Since Trump began his second term Palantir has picked up at least $300 million of new business. Many of its new contracts come from the federal government including works for the Federal Aviation Administration, the Centers for Disease Control and Prevention, and Fannie Mae, according to federal records. With Trump's administration championing artificial intelligence, cost-cutting, and private-sector partnerships, Palantir's federal business boom shows no signs of slowing. Just last week Palantir gained its biggest contract yet, an agreement to consolidate all of the military's software use over the next decade at a cost of up to $10 billion. Further to this the government has agreed to pump $795 million more into the military's core artificial intelligence software program that was built by Palantir. The Pentagon wants to expand the Maven Smart System to be used by all US forces across the globe. 'They were positioned in the right way at the right time, and they had already built the technology that had the capability to do what the administration is trying to do,' Matt Pearl, director of the Strategic Technologies Program at the Center for Strategic and International Studies (CSIS) told the Washington Post. The firm's government work picked up under Elon Musk's reign at DOGE where he trumpeted a technology-forward crusade against government waste and inefficiency. Palantir was founded by Peter Thiel, a mentor to JD Vance, and current CEO Alex Karp in the aftermath of 9/11 to help arm the state with the latest technology. Since 2008 the company has been awarded nearly $3 billion in federal funds from over 300 contracts from both Republican and Democratic administrations. Among its most high-profile uses was when its software helped orchestrate the 2011 raid that killed Osama bin Laden. Palantir was founded in the aftermath of 9/11 to help arm the state with the latest technology 'Palantir is an exceptional American company,' a senior State Department official told the Post. The official said the department was 'proud to partner with them to modernize how we carry out America's diplomacy.' 'We are proud to support the U.S. government, especially our warfighters, and our growth reflects growing government AI adoption,' a spokesperson for Palantir told the publication. Other technology stocks including Meta and Microsoft are also having a strong year, helping to push the S&P 500 up to recent record highs. In their second quarter earnings released last week Meta beat Wall Street expectations with $47.52 billion in revenue, while Microsoft brought in $76.44 billion, up 18 percent from a year ago.

Core Scientific's shareholders balk at terms of CoreWeave merger offer, FT reports
Aug 5 (Reuters) - CoreWeave's (CRWV.O), opens new tab proposed $9 billion acquisition of data centre landlord Core Scientific (CORZ.O), opens new tab is facing potential revolt, as some top shareholders of the target firm argue the deal may leave them short-changed, the Financial Times reported. Some major Core Scientific shareholders plan to vote against the deal unless the terms are revised in the coming weeks, the report said on Tuesday, citing people familiar with the matter. Reuters could not immediately verify the report. CoreWeave and Core Scientific did not immediately respond to Reuters request for a comment outside regular business hours. The shareholder vote for Core Scientific has not yet been scheduled but is expected to take place sometime this autumn, the report said. The all-stock deal, valued at about $9 billion and announced last month, highlights the race among AI infrastructure firms to secure the energy and data center capacity required to meet surging demand. CoreWeave, which provides access to data centers and Nvidia-powered AI chips, initially submitted an unsolicited, non-binding takeover offer to Core Scientific in June 2024. However, the company rejected the offer, citing that its business was significantly undervalued.

Trump's NASA chief Sean Duffy expedites timeline for nuclear reactor on the moon
President Donald Trump's NASA chief Sean Duffy has expedited the timeline to build a nuclear reactor on the moon, according to a directive obtained by The Independent . The space agency has already mentioned the benefits of developing fission surface power (FSP) on the moon and Mars. 'Relatively small and lightweight, fission systems are powerful and could enable robust operations on the Moon and Mars,' NASA writes on its website. The agency says it's currently working with the Energy Department and the space industry to design a fission power system that would provide at least 40 kilowatts of power. In a directive sent to the heads of NASA on July 31, Duffy, the acting administrator of the agency and Trump's transportation secretary, ordered that the nuclear reactor provide at least 100 kilowatts of power and be ready to launch by 2030. NASA chief Sean Duffy has expedited the timeline to build a nuclear reactor on the moon, according to a new directive () The directive, first reported on by Politico, mentioned China and Russia's joint effort to place a reactor on the moon by the mid-2030s. The two U.S. adversaries first announced their plans in March 2024. 'The first country to do so could potentially declare a keep-out zone which would significantly inhibit the United States from establishing a planned Artemis presence if not there first,' Duffy warned in the directive. NASA's Artemis campaign aims to establish the first long-term presence on the moon. During Trump's inaugural address, he said the U.S. would launch astronauts 'to plant the stars and stripes on the planet Mars.' 'It is about winning the second space race,' a NASA senior official told Politico. An artist's concept of a fission power system on the moon (NASA) In Duffy's new timeline, a Fission Surface Power Program Executive will be designated within 30 days of the directive. The executive 'is empowered to provide reporting and updates with maximum transparency directly to the Administrator,' Duffy wrote. Within 60 days, NASA will ask for industry proposals for the nuclear reactor, according to the directive. The directive mentioned Trump's budget request for the 2026 fiscal year, which includes $350 million for a new program 'that will accelerate the development of high priority technologies for Mars, (i.e. FSP).' The funding would increase up to $500 million starting in the 2027 fiscal year. Trump's budget request also proposes a huge cut to NASA, with The Planetary Society, a global non-profit space organization, reporting it's the smallest budget proposed for the agency since 1961.
