1. Anthropic Accidentally Leaks Claude Code Source Code

Anthropic PBC, the AI developer known for its “safety-first” branding, inadvertently released the internal source code for its Claude Code assistant late Tuesday. The company attributed the leak—which exposed approximately 1,900 files and 512,000 lines of code—to a human packaging error rather than a security breach. This marks Anthropic’s second major slip-up in days, following a recent report that thousands of internal files, including details on an unreleased model named “Mythos,” were stored on a publicly accessible system.

The leak gained massive traction on social media, with millions of users reportedly scouring the code for unreleased features. Cybersecurity experts have raised concerns that the exposure allows attackers to study the internal data-flow pipelines of Claude Code, potentially creating sophisticated vulnerabilities. The timing is particularly damaging as Anthropic is currently fighting a US government designation as a “supply chain risk.”

Despite these setbacks, Anthropic remains a dominant market force, having raised $30 billion in February at a $380 billion valuation.

2. Nike Shares Tumble on Gloomy Outlook

Nike Inc. shares tumbled after the retailer provided a surprisingly gloomy outlook for the coming year, complicating CEO Elliott Hill’s efforts to steer a business turnaround. Management expects revenue to decline between 2% and 4% in the current quarter, with low single-digit drops persisting through the remainder of the calendar year. These projections missed analyst estimates, which had anticipated a return to growth.

CEO Elliott Hill noted during the earnings call that while the company’s direction is clear, certain aspects of the turnaround are taking longer than expected. Nike is currently navigating global headwinds, including elevated inventory levels in Europe and the Middle East, alongside traffic disruptions caused by ongoing conflict. These challenges, combined with continued weakness in Greater China and a sharper-than-expected decline in the Converse brand, overshadowed resilient performance in North America.

Analysts warned that geopolitical volatility and tariff pressures are likely to weigh on Nike’s gross margins for the foreseeable future.

3. Eli Lilly to Acquire Centessa for $7.8 Billion

Eli Lilly & Co. is expanding its portfolio into the sleep disorder market with a deal to acquire Centessa Pharmaceuticals Plc for up to $7.8 billion. This acquisition, one of the largest in Lilly’s history, targets treatments for narcolepsy and other conditions characterized by impaired daytime alertness. Centessa is developing a new class of therapies known as orexin receptor agonists, which address the root cause of many sleep disorders by mimicking the neuropeptide missing in patients’ brains.

The potential of these drugs has drawn comparisons to insulin treatments for type 1 diabetes, as they aim to restore a critical biological deficit. Clinical trials have shown powerful efficacy in treating narcolepsy symptoms with relatively few side effects, sparking excitement that these therapies could eventually apply to a broad range of wakefulness disorders.

Through this acquisition, Eli Lilly will enter direct competition with other major pharmaceutical players, including Takeda Pharmaceutical Co. and Alkermes Plc, to bring these next-generation sleep medicines to market.

4. NASA Artemis Crew Poised for Historic Lunar Launch

NASA astronauts are set to lift off Wednesday evening on a historic 10-day mission to the lunar vicinity, marking humanity’s first return to the moon’s neighborhood in over 50 years. The crew will launch at 6:24 p.m. local time from Kennedy Space Center aboard the Boeing-made Space Launch System (SLS) rocket and the Lockheed Martin-built Orion capsule. If successful, the four-person crew will travel farther into space than any humans in history.

The mission serves as a critical dress rehearsal for NASA’s Artemis campaign, which aims to land humans on the lunar surface as early as 2028. Under NASA Administrator Jared Isaacman, the agency has outlined a $30 billion decade-long plan to establish a permanent moon base. Isaacman has also accelerated the program’s timeline, adding a 2027 mission to test docking with lunar landers developed by Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin.

The crew is scheduled to perform a lunar flyby on April 6, passing within approximately 4,112 miles of the surface.

5. SpaceX Files Confidentially for Record-Breaking IPO

SpaceX has confidentially filed for an initial public offering with the US Securities and Exchange Commission, according to people familiar with the matter. The filing positions Elon Musk’s rocket, satellite, and AI company for a potential June listing, potentially marking the first of three massive tech IPOs expected this year, alongside OpenAI and Anthropic. A representative for SpaceX did not immediately respond to requests for comment.

SpaceX could seek a valuation exceeding $1.75 trillion in the offering. The company’s valuation previously reached $1.25 trillion following its acquisition of Musk’s AI startup, xAI. Through a confidential filing, SpaceX can receive SEC feedback and refine its prospectus before making the details public.

Bloomberg News reports that the offering could raise as much as $75 billion, which would dwarf the $29 billion record set by Saudi Aramco’s debut in 2019.

6. OpenAI Shares Sour on Secondary Market

OpenAI shares have fallen out of favor on the secondary market, with some stakes becoming nearly impossible to unload as investors pivot toward its chief rival, Anthropic. Despite OpenAI’s recent massive fundraising efforts, secondary marketplaces like Next Round Capital report a sharp drop in demand. Recently, institutional investors sought to sell approximately $600 million in OpenAI shares, but found no takers among hundreds of potential buyers—a stark contrast to last year when such stakes were snapped up in days.

Meanwhile, demand for Anthropic has hit record levels, with investors indicating they have $2 billion in capital ready to deploy. The trend is driven by the perceived risk-reward ratio: OpenAI is currently valued at $852 billion, while Anthropic stands at $380 billion.

Investors are betting that Anthropic’s valuation has more room to grow and catch up with its competitor, making it a more attractive near-term play than the heavily valued OpenAI.

7. Iran Mobilizes Volunteers to “Defend Soil” Amid Invasion Threats

Iran is actively mobilizing supporters to “defend the country’s soil” as the regime prepares for a potential US ground invasion. Mass text messages and state television campaigns have called on citizens to confront threats against Iran’s borders and islands from the “American-Zionist enemy.” The Islamic Revolutionary Guard Corps (IRGC) has officially launched a recruitment drive for various roles, including active military service.

The IRGC has specifically invited volunteers as young as 12 to assist with security patrols, medical aid, and logistical support. Human Rights Watch condemned the move on Tuesday, stating that involving children in military facilities places them at severe risk and calling for an immediate ban on enlisting anyone under 18. While the online portal claims over 5 million registrations, the verification process remains minimal. Although internal opposition to the regime is widespread, the Islamic Republic maintains a committed core of supporters through the millions-strong Basij volunteer force.

Furthermore, threats from President Donald Trump regarding the seizure of Kharg Island and other strategic territories in the Strait of Hormuz have reportedly motivated even some government critics to consider joining the defense of Iranian territory.
