MPs have urged the government to halt its latest contract with Palantir, after the Guardian revealed the US spy-tech company is to gain access to a trove of highly sensitive UK financial regulation data. The Financial Conduct Authority, the watchdog for thousands of financial bodies from banks to hedge funds, has hired Palantir to apply its AI systems to two years’ worth of internal intelligence data to help it tackle financial crime. But the Liberal Democrats on Monday called for a government investigation into the contract, which the party said could be “a huge error of judgment”, while the Green party said it should be blocked over Palantir’s links to Donald Trump. Questioned on whether the UK was becoming “dangerously overreliant” on US tech companies including Palantir, the prime minister, Keir Starmer, told parliament he would prefer to have more domestic capability but added: “I don’t think we’re overreliant.” Palantir was founded by the Donald Trump-backing billionaire Peter Thiel and it supports the US and Israeli militaries and the ICE immigration crackdown. In the UK it has built up more than £500m in contracts including with the NHS, police and Ministry of Defence. Insiders at the FCA, where security-cleared Palantir staff are to gain access to FCA data in a 12-week trial, have questioned if there are sufficient safeguards to prevent its “data lake” from being exploited in unintended ways. There are concerns about the potential for data about sensitive FCA investigations into high-profile figures to be accessed during Palantir’s work. These have recently included the banker Jes Staley, who was an associate of Jeffrey Epstein, and the hedge fund boss Crispin Odey. The FCA has insisted that Palantir will be a “data processor”, not a “data controller” – meaning that it could only act on instruction from the regulator. The FCA said it would retain exclusive control over the encryption keys for the most sensitive files and the data would be hosted and stored ...

This article first appeared on GuruFocus. Elon Musk is taking a more aggressive step toward controlling the AI supply chain, outlining plans for a new semiconductor facility in Austin that could reshape how Tesla (NASDAQ:TSLA) sources critical chips. Speaking at an event in Texas, Musk said the proposed Terafab would be jointly operated with SpaceX, starting as an advanced technology fab capable of producing and testing a wide range of chips before potentially scaling further. Musk framed the move as a response to what he sees as a gap between accelerating demand for AI compute and the pace of industry supply, suggesting that without building internally, the companies may struggle to secure enough chips for robotics, autonomous driving and broader AI initiatives. The plan, however, remains early and without a defined timeline, highlighting both the ambition and execution risk. Semiconductor fabs typically take years to become operational and require tens of billions of dollars, and Musk has previously indicated the effort would begin at a smaller scale before expanding. Tesla continues to rely on existing partners including Taiwan Semiconductor Manufacturing (NYSE:TSM) and Micron Technology (NASDAQ:MU), alongside an agreement with Samsung (SSNLF) near Austin, but Musk indicated those relationships may not fully meet future demand. The Terafab is expected to eventually target advanced nodes such as 2-nanometer chips and support large-scale compute output, including 100 to 200 gigawatts annually on Earth, with additional ambitions tied to space-based systems. That broader strategy extends beyond Earth. Musk said the facility would produce two categories of chips: edge and inference processors for vehicles, robotaxis and Optimus humanoid robots, and higher-powered chips designed for space applications linked to SpaceX and xAI, which operates as a wholly owned subsidiary following its acquisition. He also outlined a vision for AI data center satellites, including a prot...

Nuclear Fuel Supply Chain Advancing Rapidly As Leading Reactor Developer X-energy Files For IPO X-energy submitted a draft registration statement to the SEC for an initial public offering of its Class A common stock. The company intends to list on the Nasdaq under the ticker “XE.” X-energy has submitted a draft registration statement on form S-1 to the U.S. Securities and Exchange Commission related to the proposed initial public offering of X-energy’s Class A common stock. X-energy intends to list on the Nasdaq Global Select Market under the symbol “XE.”… pic.twitter.com/Sh6zYpzEFw — X-energy (@xenergynuclear) March 20, 2026 The company develops the Xe-100, an 80 MWe high-temperature gas-cooled reactor (HTGR) designed for both electricity generation and high-temperature process heat. Modules can deploy individually or in four- to twelve-unit plants for scalable output. Safety features rely on its core design and proprietary TRISO-X fuel, tristructural-isotropic particles widely regarded as among the most robust nuclear fuels available. X-energy manufactures this fuel through subsidiary TRISO-X LLC to maintain quality control. Progress on their fuel supply chain is advancing rapidly. Vertical construction began in November 2025 at the TX-1 fuel fabrication facility in Tennessee. Once complete in mid-2026, the Category II facility will produce approximately 700,000 TRISO pebbles annually, sufficient for up to 11 Xe-100 reactors . TRISO-X received the first-ever Part 70 high-assay low-enriched uranium (HALEU) fuel fabrication license earlier this year, with confirmatory testing underway at Idaho National Laboratory. X-energy’s commercial pipeline now exceeds 11 GW across the United States and United Kingdom .

The installation will supply power and steam for chemical manufacturing. A construction...

Sheryl Sandberg is back at a technology startup — and it reminds her of the halcyon days at Google and Facebook. The veteran technology executive joined the board of a data center developer Nscale earlier this month, one of her first significant positions since leaving Meta Platforms Inc .’s board in 2024. On Monday, Sandberg said the London-based startup felt reminiscent of earlier times at Google and Facebook, where she played a prominent role building advertising businesses. She even compared Josh Payne , Nscale’s chief executive, to her famous former boss. Payne courted Sandberg aggressively, writing a letter to his management arguing for her to join the board, Sandberg said. “The only person I’d ever seen write like that is Mark Zuckerberg ,” she said in a joint interview with Payne on Bloomberg TV, praising Payne’s “real visionary leadership.” Nscale is one of leading so-called neoclouds, the companies renting out computing capacity to artificial intelligence developers. It competes with CoreWeave Inc. , Nebius Group NV and several other providers that have signed deals with tech giants looking to shift infrastructure spending off their balance sheets. In the process, the neoclouds have raised mountains of debt to build data centers and buy the latest semiconductors, sparking concerns about a bubble. Spun out of a cryptocurrency miner in 2024, Nscale has pledged to build major data center projects in the UK, Portugal and Norway. But none of those projects are finalized and the company has reported only minimal revenues. In March, when Nscale announced Sandberg’s appointment, the startup disclosed it had raised $2 billion from several investors, including Nvidia Corp . and Nokia Oyj , for a $14.6 billion valuation. Payne said on Monday that his company was distinct from rivals because it controlled each aspect of the technology inside data centers. “We own the land and power. We own the chips. And we own the software,” he said. Last week, Nscale said it planned...

Back in 2017, the Tax Cuts and Jobs Act increased the estate tax exemption from $5.5 million to $11.8 million per person. Since that figure was pegged to inflation, the exemption steadily rose to $13.99 million in 2025. That exemption made it much easier for wealthy individuals to pass their entire estate to their heirs upon death without incurring a tax. That exemption was originally set to expire this year and decline to about $7 million. However, the One Big Beautiful Bill Act set a new baseline exemption of $15 million for 2026 and beyond. It will also be adjusted for inflation every year, but it's a permanent change that won't expire. How will this change affect most Americans? According to the Federal Reserve, Americans aged 75 and older had a median net worth of $335,600 and an average net worth of $1,624,100 at the end of 2022. Therefore, most elderly Americans were already exempt from the estate tax. Only about 1% of American households have a net worth of over $15 million. Even if those individuals die with more than $15 million in assets, their estates won't be immediately taxed at the maximum 40% rate. Instead, it starts at 18% and goes up to 40% -- with an added "base tax" -- based on the amount by which the $15 million threshold was exceeded. Taxable Amount Base Tax Estate Tax $1 – $10,000 $0 18% $10,001-$20,000 $1,800 20% $20,001-$40,000 $3,800 22% $40,001-$60,000 $8,200 24% $60,001-$80,000 $13,000 26% $80,001-$100,000 $18,200 28% $100,001-$150,000 $23,800 30% $150,001-$250,000 $38,800 32% $250,001-$500,000 $70,800 34% $500,001-$750,000 $155,800 37% $750,001-$1,000,000 $248,300 39% $1,000,001+ $345,800 40% For example, if a person dies with $17 million in assets, their beneficiaries would need to pay a $345,800 base tax plus $800,000 (40% of the $2 million above the $15 million threshold). Yet that $1.15 million would still be equivalent to less than 7% of the total estate. What should you do with your assets in 2026? If you don't own more than $15 mi...

Larry Fink, chief executive officer of BlackRock Inc., speaks during BlackRock's 2026 Infrastructure Summit in Washington, DC, US, on Wednesday, March 11, 2026. Daniel Heuer | Bloomberg | Getty Images BlackRock CEO Larry Fink said Trump accounts could be a successful early wealth-building tool for children in the U.S., when paired with pre-existing investment vehicles. In his annual chairman's letter to investors, published Monday, Fink said this type of policy can have a good return on investment. "On average, early wealth-building accounts make it more likely for someone to earn an advanced degree, start a business, and own a home," he wrote, citing a 2023 research paper by the Aspen Institute . "We'll see how these accounts evolve, but if they are structured thoughtfully, and paired with existing investment vehicles for education and retirement (like 529 and 401(k) plans), this could be a very significant step toward more young Americans growing with their country," Fink wrote. A 529 college savings plan is another tax-advantaged investment option for families to save on a child's behalf, generally geared toward future education expenses. Alternatively, a 401(k) plan is a retirement savings tool available through most employers.

"I think the labor market could still use support from monetary policy, and that's why I dissented last meeting," Federal Reserve Governor Stephen Miran said on Monday. Meanwhile, Austan Goolsbee, president of the Federal Reserve Bank of Chicago, said he sees inflation as the more pressing concern. "At the moment, I think inflation has got to be a little ahead of the employment," he said in a televised interview. Both policymakers are trying to ascertain how the oil price shock caused by the Iran war will affect the U.S. economy in the next year or so. "Looking 12 to 18 months out, there's still not enough clarity to think that monetary policy itself should adjust in response to what has happened," Miran said during an interview on Bloomberg Television. It's still too early to conclude that the oil shock will bleed into inflation expectations, he added. He pointed out that high oil prices also depress demand, which would offset the increase in inflation, Miran said. "If it looks like the oil shock is bleeding into inflation expectations beyond the first year, then you get really concerned about second-round effects," he said. He'd also be worried if the shock appeared to cause a wage-price spiral. Miran noted that the last time the U.S. economy dealt with an oil shock, when Russia invaded Ukraine, monetary and fiscal policies were very different. Both were at "all-time historical accommodative levels," he said. "That's not the case right now. We're not hitting the gas on demand that would interact with the higher oil price in a way that would reverberate through the economy right now. That's not the case at all." Meanwhile, regarding the Iran war's effect on inflation, Goolsbee said, "It's an intense moment. We got a lot that hangs in the balance," Goolsbee said. Through 2025, the U.S. went through another inflation shock with the sweeping tariffs imposed by the Trump administration. "We stopped making progress on the inflation front," he said. "At best, it stalled ...

Amazon seen as undervalued despite AI capex concerns: Jefferies Proactive Investors

is transportation editor with 10+ years of experience who covers EVs, public transportation, and aviation. His work has appeared in The New York Daily News and City & State. Donut Lab is on a mission to prove to the world its solid-state battery is real, one independent test at a time. We’ve seen speed charging tests, extreme heat tests, and not-a-supercapacitor tests. Today’s test is to see how the battery hold up under damage. The results: while it could barely sustain a charge, it didn’t burst into flames, which Donut Lab sees as a victory. If you’ll recall, during the extreme heat tests, the pouch surrounding Donut’s battery lost its vacuum seal. This led to researchers at Finland’s state-owned VTT Technical Research Centre, which conducted all of the lab’s previous tests, to explore whether the cell could still function under these high-stress, high-temperature conditions. As Donut notes, damage such as the one sustained by its pack during the heat test has been known to cause fire or thermal runaway in conventional lithium-ion batteries. The startup wanted to see whether its solid-state battery could avoid a similar calamity. Researchers conducted three tests: a baseline test of 5 cycles at 1C (26 amps); a high-stress test of 50 cycles at 5C (130 amps) ; and another final baseline test of 5 cycles at 1C to measure degradation. After the tests, the team observed a sharp drop in energy capacity, from 24.7 Amp-hours to 11.2 Ah, or a loss of approximately 55 percent. They also recorded a drop in efficiency from 89.6 percent to 83 percent, and noted a 17 percent increase in the pack’s thickness. Given the damage sustained by the pack, the results shouldn’t be that surprising. The loss of the vacuum seal certainly accelerated the battery’s degradation and contributed to its thick, swollen state after the test. Still, Donut Lab said this was further proof that its battery can avoid some of the worst outcomes of a damaged lithium-ion battery. “No temperature spikes, n...
