Executive Summary
The last remaining nuclear arms control treaty between the United States and Russia officially expired on Friday, ushering in an era without formal limits on the world’s largest arsenals for the first time in over 50 years. In technology, a massive spending spree on artificial intelligence infrastructure by Amazon, Google, and Microsoft, totaling an estimated $660 billion for the year, triggered a sharp sell-off in their stocks as investors questioned the near-term profitability of such outlays. Meanwhile, British Prime Minister Keir Starmer is facing a significant political crisis over revelations about his former U.S. ambassador’s financial and informational ties to the late Jeffrey Epstein.
Geopolitics & Security
Last US-Russia Nuclear Treaty Expires, Raising Arms Race Fears
The New START treaty, the final arms control agreement limiting the long-range nuclear arsenals of the United States and Russia, officially expired on Friday, leaving the world’s two largest nuclear powers without treaty-bound limits on their strategic weapons for the first time in over half a century. United Nations Secretary-General Antonio Guterres described the expiration as a “grave moment for international peace and security,” warning that the risk of nuclear weapon use is the highest in decades.
President Donald Trump rejected a proposal from Russian President Vladimir Putin for a voluntary extension of the treaty’s limits, stating on his Truth Social platform that the pact was “badly negotiated” and “grossly violated.” Instead, Mr. Trump called for U.S. nuclear experts to work on a “new, improved, and modernized Treaty” that includes China. Beijing has previously stated it would not participate in such a treaty. The Kremlin expressed regret over the expiration, with spokesman Dmitry Peskov asserting Moscow would maintain a “responsible, thorough approach to stability when it comes to nuclear weapons.”
The expiration removes the last formal guardrails on stockpiles that together account for approximately 85% of global nuclear warheads. While reports from Abu Dhabi suggested U.S. and Russian officials may have discussed an informal agreement to “operate in good faith” and observe the treaty’s terms for six months, the White House has not confirmed any such arrangement. The treaty’s lapse was exacerbated by the conflict in Ukraine, with Russia suspending verification inspections and blaming Western support for Kyiv for the breakdown in relations.
The absence of a formal agreement leaves a significant void in global nuclear risk management, with analysts and some U.S. allies expressing concern about a potential new arms race and increased risk of miscalculation. Vice President J.D. Vance indicated the administration would seek to “draw down the amount of nuclear weapons that exist in the world” by working with both China and Russia, but the path to any new multilateral framework remains unclear.
US and Iran Hold Tense Talks in Oman Amid Military Posturing
Senior officials from the United States and Iran convened in Muscat, Oman, on Friday for direct talks aimed at de-escalating military tensions that have brought the two nations to the brink of conflict. The discussions, led by Iranian Foreign Minister Abbas Araghchi and a U.S. delegation including special envoy Steve Witkoff and Jared Kushner, temporarily defused immediate threats of military action from Washington. President Donald Trump acknowledged the negotiations, stating that Iran “don’t want us to hit them.”
The talks occurred under a cloud of military posturing and diplomatic friction. The U.S. recently issued a stark warning for its citizens to “leave Iran now” and has deployed the USS Abraham Lincoln carrier strike group to the region. Iran, meanwhile, announced a technical upgrade to its ballistic missile arsenal and a doctrinal shift to an offensive military posture. Russian Foreign Minister Sergey Lavrov described the situation as “explosively dangerous,” warning that an escalation could trigger a wider regional conflict.
Disagreements over the agenda have plagued the diplomatic effort. The Trump administration is reportedly seeking concessions beyond Iran’s nuclear program, including limits on its ballistic missile development and its support for regional proxy groups. Tehran has characterized these demands as an unacceptable infringement on its sovereignty, insisting the talks focus exclusively on its nuclear program and the lifting of sanctions. The diplomatic overtures follow a significant escalation last June, which involved Israeli strikes on Iranian nuclear facilities and subsequent U.S. intervention.
While the agreement to meet suggests a mutual, albeit fragile, interest in avoiding a wider war, the gap between the two sides remains substantial. Iranian officials are reportedly exploring a Russian-brokered proposal as a potential pathway to de-escalation, though details remain unconfirmed. The outcome of the Muscat talks will be critical in determining whether a diplomatic off-ramp can be found or if the region is headed for further confrontation.
Panama Canal Ruling Voids Chinese Firm’s License, Fueling US-China Tensions
Panama’s highest court has voided a license for CK Hutchison Holdings, a subsidiary of a Hong Kong-based conglomerate, to operate two key container terminals at the Panama Canal. The decision is widely seen as a victory for the United States, which has prioritized blocking Chinese influence over the vital trade route, and has sharply escalated geopolitical tensions. Beijing issued a stern warning, stating Panama will “inevitably pay a heavy price both politically and economically” unless it reverses the ruling.
Panamanian President Jose Raul Mulino dismissed the threats, asserting his nation’s commitment to the rule of law. However, analysts view the ruling as a politically driven decision that could set a destabilizing precedent for global port investments, which are increasingly seen as strategic geopolitical assets. CK Hutchison Holdings, which strongly disagreed with the court’s determination, has initiated international arbitration proceedings. APM Terminals, part of the Danish shipping giant Maersk, has been appointed as the interim administrator for the affected ports.
The dispute highlights the broader struggle for influence between Washington and Beijing in Latin America, a key objective of the Trump administration’s foreign policy. The use of political pressure to invalidate long-term commercial concessions underscores the increasing intertwining of trade and national security. The fallout is expected to be prolonged, with lingering questions about port security and the stability of international investments in critical infrastructure.
US and Russia Resume Military Dialogue Amid Ukraine Peace Talks
The United States and Russia have agreed to re-establish high-level military-to-military dialogue, a communication channel that had been suspended since 2021, before Russia’s full-scale invasion of Ukraine. The agreement was finalized on the sidelines of the second round of Ukraine peace talks in Abu Dhabi, which included representatives from Washington, Kyiv, and Moscow. U.S. European Command stated the channel will “provide a consistent military-to-military contact as the parties continue to work towards a lasting peace.”
The resumption of direct military communication marks a significant step toward managing potential de-escalation and avoiding miscalculation, even as the war in Ukraine approaches its fourth year. The talks in Abu Dhabi, facilitated by the U.S., also resulted in the first prisoner of war exchange between Ukraine and Russia in five months. However, some analysts, like former U.S. deputy assistant secretary of defense Jim Townsend, view the move with skepticism, describing it as “contradictory” for reintroducing a sense of normalcy while Russia’s aggression continues.
Despite the diplomatic efforts, significant hurdles to a peace settlement remain. Russia is reportedly demanding Ukrainian troop withdrawal from parts of the Donbas region, a condition Kyiv has rejected, proposing instead a freeze along current front lines. Russia has also continued its strikes on Ukrainian infrastructure, impacting power supplies amid freezing temperatures. Ukrainian President Volodymyr Zelenskyy recently revealed that an estimated 55,000 Ukrainian soldiers have been killed in the conflict, a figure that underscores the brutal, ongoing cost of the war.
AI & Technology
Tech Giants’ AI Spending Spree Sparks Market Sell-Off
A massive spending spree on artificial intelligence by the technology industry’s largest companies has triggered a sharp sell-off in their stocks, as investors grow concerned that the gargantuan outlays are outpacing the near-term potential for profits. Amazon, Google, and Microsoft are planning to spend an estimated $660 billion combined on AI infrastructure in the current year, primarily on building vast data centers and acquiring specialized chips.
Amazon sent the most significant shock through the market, announcing plans for $200 billion in capital expenditures for 2026, a figure that far exceeded Wall Street’s expectations of around $150 billion. The news, which came as the company reported strong 24% revenue growth in its Amazon Web Services cloud division, caused the company’s stock to fall in after-hours trading. Similarly, Google’s parent, Alphabet, projected a substantial increase to between $175 billion and $185 billion for 2026, more than double its 2025 spending, which also weighed on its shares.
Analysts are divided on the strategy. Some argue that the investments are necessary to secure a dominant position in the burgeoning AI market and are justified by the rapid adoption of AI services. Others express apprehension about the sheer scale of the spending and the potential for an AI bubble. “It is not clear whether that’s a good or a bad thing,” Deutsche Bank analysts wrote, acknowledging the unprecedented nature of the capital plans. The market’s reaction suggests a prevailing skepticism about immediate returns.
The performance of these tech giants will now hinge on their ability to translate the massive infrastructure investments into tangible revenue and profit that can satisfy anxious investors. In a notable contrast, Apple, which has largely abstained from the AI capital expenditure race, has seen its stock perform favorably, offering a different perspective on navigating the current market.
OpenAI and Anthropic Launch Rival AI Models in Escalating Competition
OpenAI and Anthropic, two of the most prominent artificial intelligence developers, unveiled new flagship models within an hour of each other on Thursday, intensifying their race for dominance in the lucrative enterprise market. Anthropic announced Claude Opus 4.6, which it said showed improvements in long-context reasoning for tasks in law and finance. OpenAI countered with GPT-5.3 Codex, a model it said was specifically optimized for advanced, agent-based computer programming.
The near-simultaneous releases highlight the rapid pace of innovation as both companies vie for long-term contracts with large corporate clients. According to benchmark results released by the companies, each model appears to have distinct strengths. Claude Opus 4.6 reportedly excels in complex information retrieval within a 1-million-token context window, while GPT-5.3 Codex demonstrated superior performance on agentic coding benchmarks. OpenAI also noted that its new model was instrumental in debugging and managing its own development, a capability it calls “agentic coding.”
These launches come as OpenAI also announced Frontier, a new enterprise platform designed to help businesses build, deploy, and manage AI agents within their existing workflows. The platform, which counts Intuit, State Farm, and Uber as early adopters, is positioned as a centralized management layer, allowing companies to “hire AI coworkers” for tasks like data analysis. The move places OpenAI in direct competition with other firms developing agent management solutions, a market that is growing as AI agents become more prominent in business.
AI Boom Fuels Component Shortages, Delaying Consumer Electronics
The voracious demand for hardware to power the artificial intelligence boom is creating significant component shortages that are rippling across the consumer electronics industry, leading to production delays and price increases. Qualcomm, a major chipmaker, saw its stock drop 10% after it issued weak guidance, citing memory supply constraints as the sole reason. The company’s chief executive, Cristiano Amon, stated that demand for AI data centers is diverting dynamic random access memory (RAM) away from consumer products.
The shortages are having a direct impact on product launches. Valve, the gaming technology company, officially delayed its planned Steam Machine and Steam Frame VR headset, citing uncertainty around the price and availability of RAM and storage. The company acknowledged that the supply situation had worsened since the products were first announced, forcing a revision of its shipping and pricing strategies.
Industry analysts predict further price inflation for consumer PCs, as memory prices have reportedly soared between 80% and 90% year-on-year. While new fabrication plants are under construction, they are years away from contributing to the supply. The situation is severe enough that major PC brands are reportedly considering sourcing memory chips from Chinese manufacturers for the first time, a move that would underscore the depth of the supply chain crisis.
Economy & Markets
Bitcoin Plunges to 15-Month Low, Wiping Out Trump-Era Gains
The value of Bitcoin plunged to a 15-month low of approximately $60,255 this week, a drop of more than 52% from its peak in late 2025 that has erased all gains made since President Trump took office. The broader cryptocurrency market has shed $2 trillion in total capitalization since its October peak, and investor sentiment has fallen to a level of “extreme fear” not seen since the Terra Luna collapse in mid-2022, according to the Crypto Fear and Greed Index.
Analysts attribute the severe downturn to a confluence of factors, including uncertainty surrounding Federal Reserve interest rate policy, a strengthening U.S. dollar, and broader stress in global bond and technology markets. The slump is testing the narrative of Bitcoin as “digital gold,” as its price movements increasingly correlate with traditional risk assets like equities. The market’s volatility is further highlighted by the fact that Bitcoin’s current value is less than it was at the start of President Trump’s second term, a period that began with expectations of a more crypto-friendly regulatory environment.
While Mr. Trump’s earlier supportive stance fueled a rally, subsequent geopolitical and regulatory uncertainties have contributed to the current sell-off. A proposed Trump-backed bill to regulate digital assets has stalled in the Senate, reflecting deep divisions among policymakers. The scrutiny faced by the Trump family’s own cryptocurrency firm, World Liberty Financial, has added another layer of complexity. Some analysts warn that the market may be entering a prolonged transition phase rather than a short-term correction.
US Layoffs Surge to 15-Year High as Labor Market Cools
U.S. companies announced 108,435 job cuts in January, the highest figure for that month since 2009 and an 118% increase from the previous year, according to data from the employment firm Challenger, Gray & Christmas. The surge in layoffs, led by major workforce reductions at companies like Amazon and UPS, signals a significant pullback in hiring and a broader cooling of the American labor market.
The rise in job cuts coincides with a decline in job openings, which fell to 6.5 million in December, the lowest level since September 2020, according to the Labor Department. The transportation and technology sectors were particularly hard-hit, accounting for over 53,000 of the announced cuts in January. Amazon is closing its Fresh grocery stores and eliminating 16,000 positions, while UPS is planning 30,000 job reductions. The current pace of job growth has slowed considerably from the robust hiring of recent years.
Employers cited losing commercial contracts, economic conditions, and restructuring as reasons for the cuts. Some companies also pointed to the adoption of artificial intelligence, though it is unclear to what extent AI is a primary driver versus a pretext for broader workforce adjustments. The Federal Reserve is closely monitoring these labor market signals as it weighs future monetary policy decisions.
US Launches ‘Project Vault’ to Counter China on Critical Minerals
The United States has launched a multi-pronged strategy to counter China’s dominance in the supply of critical minerals, which are essential for defense, renewable energy, and advanced technology. President Trump unveiled “Project Vault,” a $10 billion initiative backed by the U.S. Export-Import Bank, to build a strategic stockpile of over 50 critical minerals and expand domestic processing capacity.
Concurrently, the administration is working to establish a critical minerals trade bloc with allied nations. At a ministerial meeting hosted by Secretary of State Marco Rubio with officials from 55 countries, Vice President J.D. Vance announced plans for a “preferential trade zone” that would use coordinated price floors and adjustable tariffs to ensure access for member nations and prevent market flooding by low-cost suppliers. Secretary Rubio noted that these minerals are “heavily concentrated in the hands of one country.”
These initiatives reflect a growing recognition in Washington and allied capitals of the strategic vulnerability created by China’s control over global production and refining. However, the push has drawn criticism that countries in the Global South, which are often the primary extractors of these raw materials, are likely to shoulder a disproportionate share of the costs and environmental burdens associated with the new strategy. The administration has not detailed how it will address these international economic dynamics.

Geologists Probe Earth’s Mantle as Quantum Tech Leaps Forward
Scientists have reported significant advancements across multiple disciplines, from identifying massive, ancient structures deep within the Earth to pushing the boundaries of quantum technology. Geologists have pinpointed two continent-sized structures in the Earth’s mantle that they say have influenced the planet’s magnetic field for over 265 million years, offering new insights into the forces that govern its protective shield.
The discovery, published in Nature Geoscience by researchers at the University of Liverpool, identifies two ultrahot structures, known as large low-shear-velocity provinces, located 2,900 kilometers beneath the surface. The researchers found that these anomalies alter the flow of liquid iron in the Earth’s core, thereby shaping the planet’s irregular magnetic field and helping to explain its long-term behavior.
In parallel, researchers in China have made strides in quantum technology. A team led by Pan Jianwei at the University of Science and Technology of China demonstrated tamper-proof quantum communication over 100 kilometers of optical fiber, a breakthrough that enhances security by ensuring integrity even if the communication devices themselves are compromised. Separately, researchers at Hefei National Laboratory built a quantum battery inside a quantum computer, demonstrating that quantum interactions can lead to charging speeds up to twice that of classical batteries, a crucial step toward powering future quantum systems.

Starmer Faces Crisis in Britain Over Aide’s Ties to Epstein
Prime Minister Keir Starmer of Britain is confronting a severe political crisis and speculation about his leadership following revelations about his former appointee, Lord Peter Mandelson, and his connections to the late sex offender Jeffrey Epstein. Mr. Starmer appointed Lord Mandelson as the U.K.’s ambassador to the United States in 2024, a decision now under intense scrutiny after newly released documents suggested Lord Mandelson received $75,000 from Epstein and may have leaked confidential government information to him in 2009 and 2010.
Mr. Starmer has apologized to Epstein’s victims, stating he was “lied to” by Lord Mandelson and did not know the full extent of their relationship. The scandal has deepened divisions within the governing Labour Party, with some backbenchers calling for the resignation of Mr. Starmer’s chief of staff, Morgan McSweeney, who is blamed by some for pushing for the appointment. Lord Mandelson has resigned from the Labour Party and the House of Lords, denying any wrongdoing but admitting he has no recollection of receiving the payment. British police have opened an investigation into alleged misconduct in office.
The controversy has paralyzed Mr. Starmer’s government, with opposition parties seizing on the issue and the Liberal Democrats calling for a confidence vote. The Prime Minister has been hosting meetings with members of Parliament at his Chequers retreat to quell dissent, but reports suggest a simmering resentment persists, with some believing his position is becoming untenable as the ongoing release of Epstein’s files continues to generate damaging headlines.

The AI-Augmented Coder: Debating a “Renaissance” in Software Development
The release of OpenAI’s GPT-5.3-Codex served as a catalyst for a timeline-wide discussion on the rapidly changing nature of software development. Sam Altman announced the new model with the simple declaration, “You can just build things,” framing the future as one where “people will manage teams of agents to do very complex things.” This vision was echoed by YC President Garry Tan, who described the current moment as a “renaissance in front of our eyes.” YC is operationalizing this belief by now asking applicants to submit transcripts from their AI coding tools, signaling that the process of building with AI is as important as the final product. This sentiment was taken to its optimistic extreme by Pieter Levels, who now advises aspiring builders that “you don’t need to know how to code anymore” to create products.
Providing a more grounded counterpoint, Google AI researcher François Chollet offered a detailed analysis arguing against the idea of imminent job replacement. Drawing a parallel to the translation industry, where AI has achieved near-full automation, he noted that the number of full-time translators has not decreased. Instead, the job has shifted to supervising AI, task volume has increased, and freelance rates have fallen. Chollet predicts a similar pattern for software engineering, attributing current and future tech layoffs to economic fears and capex needs rather than automation. He argues that the gap between automating verifiable tasks and replacing a full job role, which contains many non-verifiable elements, remains vast.
“For this reason the gap between ‘AI can automate most of these tasks’ and ‘AI can fully replace this job’ will remain for a very long time, across nearly all jobs. Like with self-driving, working 99% of the time is not nearly good enough to remove the human.”

Beyond the Hype: Crypto’s Push for Novelty and On-Chain Utility
A current of introspection is running through the crypto ecosystem, led by Ethereum co-founder Vitalik Buterin’s detailed critique of the Layer 2 (L2) landscape. In a lengthy thread, Buterin expressed frustration with the proliferation of what he terms “copypasta EVM chains,” arguing that the ecosystem has become too comfortable with forking existing infrastructure rather than pursuing genuine innovation. He urged developers to move beyond simple optimistic rollups and focus on bringing fundamentally new capabilities to the table.
“Build something that brings something new to the table. I gave a few examples: privacy, app-specific efficiency, ultra-low latency, but my list is surely very incomplete.”
— @VitalikButerin
This call for substance over speculation is finding resonance in practical applications. Y Combinator announced that its funded startups can now opt to receive their $500k investment in USDC stablecoins, a move Stripe CEO Patrick Collison highlighted as a key integration of stablecoins into core startup financing. Meanwhile, Coinbase CEO Brian Armstrong pointed to the underlying infrastructure’s growing resilience, noting that the Base network sustained over 1,000 transactions per second during market volatility. Armstrong also endorsed the view that the convergence of crypto and AI is a powerful trend that is only just getting started, suggesting a future where verifiable computation and intelligent agents are deeply intertwined.
Tech Leaders Sharpen Political Focus Amid Regulatory and Geopolitical Debates
The timeline revealed a heightened focus among tech leaders on political and regulatory battles, both at home and abroad. Elon Musk amplified commentary targeting European regulators, sharing posts alleging that the European Commission engages in election interference and that the U.S. Congress is considering stripping EU officials of sovereign immunity over censorship demands. This sentiment was mirrored by Basecamp’s David Heinemeier Hansson, who highlighted Telegram’s fight against “dangerous new regulation” in Spain, framing it as a broader struggle for digital freedom.
Domestically, YC President Garry Tan continued his vocal engagement in California politics, retweeting reports alleging that LA Mayor Karen Bass altered a fire analysis report and arguing that the city needs leaders who are “not captured by special interests.” On the geopolitical front, Lux Capital’s Josh Wolfe maintained a sustained campaign to draw attention to the situation in Iran. He voiced strong support for exiled crown prince Reza Pahlavi as a leader for a post-regime Iran and offered a sharp analysis of why the mass killings there have failed to generate the global outrage seen in other conflicts.
“WHEN you understand WHY no global outrage on Iran (no paid viral TikTok videos, no paid protestors, no paid Tucker/Candace/Fuentes, no China or Russia or Qatar NGO front orgs, no planted campus fronts, no coordinated campaigns of ‘genocide’) THEN you will understand lots more”
