The world’s richest person has repeatedly signaled his support for the chip executive.
Chuck Schumer and Hakeem Jeffries are both cautious, calm, compromise-minded leaders fantasizing about a serious, sensible Democratic-run Congress. But social media is a temptress no party leader has tamed. The seduction of attention, likes and followers invariably proves too strong for the savviest, most self-promotional politicians to resist.
The AI boom without Jensen Huang will test a hard truth: Even if the tech world has grown somewhat less reliant on Nvidia's chips, it remains highly dependent on its checkbook. Why it matters: With rival chips maturing and recent software breakthroughs, the tech ecosystem has achieved what would've seemed impossible a year ago: a viable path around Nvidia. But replacing a CEO willing to bankroll startups, backstop billions in cloud debt and aggressively fund rivals to the…
Oil markets are heading into an unusual period as the Iran conflict remains in dangerous limbo: The supply crunch is easing, but prices could stay stubbornly high. Why it matters: While gasoline prices have dropped lately, don't expect pre-war levels anytime soon even as Middle East exports fitfully recover. Getting oil out of the region is expensive, which filters down to consumers.
The rapid deployment of artificial intelligence in hospitals and clinics is leading the nation's biggest physicians group to lobby for new legal protections if AI harms patients. Why it matters: The use of increasingly sophisticated AI tools and recommendations is blurring the lines around negligence in health care, raising questions about whether doctors should be held responsible for decisions that rely on software. There's added urgency as autonomous AI takes on more…
Treasury Secretary Scott Bessent said in a Friday interview that while his department and others agreed on placing Megaspeed on a special list of companies that pose national security concerns, the Commerce Department "has the pen." Why it matters: Bessent didn't deny reports of tension between him and Commerce Secretary Howard Lutnick, who has come under scrutiny for his inaction over Megaspeed. The Singapore tech company has been accused of illegally diverting U.S.…
A defining story of this decade has been a series of global economic shocks: pandemic, war and geopolitical shifts. New research quantifies a rising set of vulnerabilities for the global trade system. The big picture: Many crucial global goods are built on supply chains that have one or more Achilles' heels, a report from the consulting firm McKinsey finds — a critical input, concentrated suppliers and geopolitical strain.
The movement to prevent House Democratic Leader Hakeem Jeffries (D-N.Y.) from becoming speaker is struggling to get off the ground due to a fatal flaw: Nobody else wants the job. Why it matters: Despite the phone calls and online petitions, the demands from progressive holdouts, Jeffries' ascent has become a self-fulfilling prophecy. The House Democrats most often floated as potential challengers don't appear to be interested: Rep.
The FAA lifted its nationwide ground stop Friday night after hours of chaos and thousands of delays and cancellations. Why it matters: The effects of the rare and extreme move will likely ripple through the weekend, with travelers stranded and airlines' planes and crews out of position. Driving the news: In a Friday evening press conference, Transportation Secretary Sean Duffy said the ground stop was issued after outdated air traffic control communications equipment…
The Signal Insight Jennifer Morgan, who became the first female leader of a DAX-listed company when Germany’s SAP named her co-CEO in 2019, now leads a US business processing $1 trillion of payroll data each year. UKG, formed in 2020 from the merger of Ultimate Software and Kronos, provides HR services and workforce management technology to organizations employing 65 million hourly and frontline workers in industries including retail, healthcare, and manufacturing. Since…
Democrats are facing heavy pressure from AI safety groups to ramp up oversight of the Trump administration’s AI policy when they take power next year, according to two letters shared first with Semafor. The AI accountability group Guardrails Action and nine other groups wrote to Senate Minority Leader Chuck Schumer and House Minority Leader Hakeem Jeffries, arguing that voters were clear in the midterms that they want AI and government accountability. The groups seized on…
The News Nigeria’s electoral commission will obey any court ruling on whether the main challenger to President Bola Tinubu is eligible to contest January’s presidential election, its chairman said, potentially handing the judiciary a key role in Africa’s biggest poll. Former Vice President Atiku Abubakar is set to appeal last week’s high court ruling that invalidated his candidacy. The chair of the Independent National Electoral Commission, Joash Amupitan, speaking at the…
House Democrats are looking askance at Rep. Jim Jordan’s election as minority leader, given the Ohio Republican has few relationships across the aisle — but next year, they might not have to work with him much. Democrats are likely to put up bills at the beginning of next Congress that could draw some bipartisan support like a stock trading ban, but their cushy House majority is likely to eliminate the need for Republican support on key funding and rule votes.
A bipartisan 82% majority of Americans think that prediction markets should be regulated as gambling products instead of financial ones, a poll conducted by Qualtrics on behalf of the American Gaming Association found. The poll also found that 75% say using the markets to buy and sell sports-related event contracts is the same as using a sportsbook to bet on sports. The group is using the findings, shared first with Semafor, to reinforce its argument that states and…
US Commerce Secretary Howard Lutnick faced mounting pressure from lawmakers over the Trump administration’s handling of the Nvidia scandal. Lutnick has been criticized — including, reportedly, by the Treasury secretary — over his department’s failure to sanction Megaspeed, an Nvidia customer, for allegedly smuggling its chips; revelations that a Megaspeed executive, who is accused of ties to Chinese intelligence, had an affair with Nvidia CEO Jensen Huang led to Huang’s…
A growing consensus in Washington towards tightening restrictions on China’s access to cutting-edge chip technology will have a negative, long-term impact on the AI sector and the US itself, a leading outlet warned. New regulations and legislation aiming in particular to cut off “remote access” — whereby Chinese firms use US-made processors via data centers in third countries — “will have consequences,” SemiAnalysis warned, “and we don’t think politicians are thinking…
European leaders were set to hold talks on how to compete with the US and China in the AI race, but analysts voiced skepticism the EU could overcome structural shortcomings. The summit in Dublin, the first of its kind to focus solely on AI, is expected to be overshadowed by debate over financial support for Ukraine, discussion over who speaks for the bloc internationally, and horse-trading over an EU-wide budget. The EU’s efforts on AI have in any case so far been…
The Scene When Massachusetts-based Commonwealth Fusion Systems looked for companies that could produce large metal components and complex machinery for its prototype, it landed on the oil and gas industry. CEO Bob Mumgaard said the hydrocarbons industry shares many of the same skills and tools that fusion developers need to achieve a breakthrough and eventually take a share of the energy mix. The UAE is well positioned to use its expertise in oil and gas to adopt fusion…
US President Donald Trump threatened to double tariffs on Mexico if it doesn’t stop a migrant caravan heading for the border, ratcheting up tensions with the US’ biggest trading partner. Illegal crossings of the US-Mexico border have plummeted during Trump’s second term partly because Mexico, which sends the vast majority of its exports to its northern neighbor, has deployed troops to stem the flow and win over the White House. The Democratic Party’s recent electoral…

The rapid adoption of AI coding tools has led to an unprecedented increase in the volume and velocity of generated code. As development teams produce larger changes at a faster pace, traditional code review processes have failed to scale, creating significant operational bottlenecks that delay software delivery into production environments.
Why now: Code review has transformed into one of the most prominent constraints on getting software into production because teams relying heavily on AI coding agents write code faster and in greater volume, causing human reviewers to face larger changes and significantly longer wait times.
Uncertainty: The long-term effects of adopting automated AI code reviewers versus human-led review pipelines remain unclear, particularly regarding potential blind spots in catching complex logical bugs or security vulnerabilities across diverse enterprise codebases.
Organizations deploying AI agents face rapidly multiplying operational expenses driven by repetitive execution tasks, cron job polling, and heavy infrastructure utilization, prompting prominent industry stakeholders to acknowledge that agent run costs have begun to explode.
Why now: Exploding operational costs and inefficient execution loops are directly constraining enterprise scalability, as highlighted by industry leaders who note that agent costs have truly started to explode and commercial deployment limits are forcing teams to seek immediate infrastructure efficiencies.
Uncertainty: It remains unclear what percentage of enterprise agent workloads can adopt these cost-reduction mechanisms without sacrificing task accuracy, or how diverse cloud provider pricing models will impact long-term unit economics across varying production scales.
