SoftBank Secures Record $40 Billion Bridge Loan to Fund OpenAI Stake

SoftBank Group closed a $40 billion non-collateralized bridge loan on Friday — the largest corporate bridge facility ever arranged — to fund its massive stake in OpenAI and general corporate purposes. The 12-month facility was arranged by JPMorgan Chase, Goldman Sachs, Mizuho Bank, Sumitomo Mitsui Banking Corp, and MUFG Bank, Bloomberg reported. The loan backs SoftBank’s $30 billion follow-on investment in OpenAI through its Vision Fund 2, part of a $110 billion funding round that valued the ChatGPT maker at approximately $730 billion.

SoftBank shares retreated on the news as investors weighed the balance-sheet strain of Masayoshi Son’s latest AI gamble. The investment cements SoftBank as OpenAI’s single largest financial backer and reflects the extraordinary scale of capital now flowing into frontier AI companies — capital that increasingly requires debt financing on top of existing equity commitments. The loan’s 12-month maturity suggests SoftBank expects to refinance or monetize its position quickly, potentially through OpenAI’s anticipated IPO later this year.

Leaked Anthropic “Mythos” Model Sends Cybersecurity Stocks Tumbling

Cybersecurity stocks suffered their worst single-day selloff of 2026 after a Fortune report revealed that Anthropic is testing a powerful new AI model called “Mythos” — part of a previously undisclosed tier called “Capybara” — that appears capable of identifying and exploiting software vulnerabilities at machine speed. Shares of CrowdStrike, Palo Alto Networks, and Zscaler dropped more than 5%, while Cloudflare shed 3.2%. The Global X Cybersecurity ETF fell as much as 6.1%, extending its year-to-date decline past 20%.

The leak originated from a security lapse at Anthropic on March 26, when close to 3,000 internal assets — including draft research documents — were found to be publicly accessible despite never having been published to the company’s official channels. The Capybara tier would reportedly exceed the capabilities of Anthropic’s current top-tier Opus model. The market reaction reflects a deepening anxiety about AI’s dual-use potential: the same capabilities that make frontier models useful for defensive cybersecurity could, in adversarial hands, systematically outpace the detection and response tools that the cybersecurity industry sells today.

Anthropic Weighs IPO as Soon as October — As Judge Blocks Federal Ban

In a day of whiplash developments, Anthropic confirmed it is considering an initial public offering as early as October 2026, with bankers expecting the company to raise more than $60 billion — a figure that would rival the largest IPOs in history. The company was valued at $380 billion in its February Series G round and has seen its annualized revenue top $19 billion, more than double the $9 billion it reported roughly three months earlier, according to The Information.

Separately, U.S. District Judge Rita Lin issued a preliminary injunction on Thursday blocking the Trump administration’s “supply chain risk” designation of Anthropic and halting a presidential directive ordering all federal agencies to cease using Anthropic’s technology. Judge Lin called the government’s actions “Orwellian” and found strong evidence of First Amendment retaliation, noting the designation is “usually reserved for foreign intelligence agencies and terrorists, not American companies.” The ruling — which the government has seven days to appeal — represents a landmark judicial check on executive power over AI procurement and dramatically strengthens Anthropic’s legal and commercial position heading into any IPO process.

Google Warns Quantum Computers Could Break Encryption by 2029

Google accelerated its “Q-Day” timeline this week, warning that quantum computers powerful enough to break widely used encryption systems could arrive as early as 2029 — significantly sooner than the 2031 target previously set by the NSA. VP of Security Engineering Heather Adkins and Senior Staff Cryptography Engineer Sophie Schmieg cited faster-than-expected advances in quantum hardware, error correction, and factoring resource estimates as drivers for the compressed timeline.

Google plans to integrate post-quantum cryptography (PQC) into Android 17 by June and is urging the broader industry to begin migration immediately. The company specifically warned of “store now, decrypt later” attacks, in which adversaries harvest encrypted data today with the expectation of decrypting it once quantum-capable machines are available. The revised timeline puts pressure on every organization handling sensitive data — from financial institutions to defense contractors — to begin the multi-year transition to quantum-resistant algorithms before the window closes.

Septentrio Launches AsteRx EB Enclosed Receiver for Industrial and Maritime Automation

Belgian GNSS specialist Septentrio expanded its enclosed receiver portfolio with the AsteRx EB, a compact, ruggedized multi-frequency GNSS receiver targeting industrial robots, port logistics, marine platforms, and scalable automation deployments where rapid integration and environmental resilience are critical. The product was announced March 26 and is available for order immediately through Septentrio’s global distribution channels.

The AsteRx EB is housed in an IP67-rated enclosure designed for outdoor deployment in harsh weather, vibration, and dust conditions without requiring additional protective housing. In a dual-antenna configuration, it delivers sub-degree GNSS heading for platforms that need orientation as well as RTK positioning — a requirement for automated guided vehicles, autonomous port cranes, and precision marine operations. The receiver’s built-in AIM+ anti-jamming and anti-spoofing technology provides interference mitigation at the receiver level, complementing Septentrio’s advanced multipath-resistant algorithms that maintain reliable positioning in environments with foliage, reflective surfaces, or proximity to GNSS interference sources. The compact form factor and straightforward mounting are designed to reduce integration time for OEMs scaling from prototype to production runs — addressing a persistent friction point for industrial automation programs that need hundreds or thousands of GNSS-equipped platforms deployed consistently.

Researchers Reveal Hidden Signal Shifts in GPS and BeiDou Flex Power Operations

A multi-institution research team spanning Space Engineering University, the Beijing Institute of Tracking and Telecommunications Technology, the Shanghai Astronomical Observatory, and Wuhan University published findings in Satellite Navigation revealing how flex power operations in GPS and BeiDou satellites — in which ground controllers redistribute signal energy to strengthen specific transmissions without increasing total satellite power — introduce hidden errors into high-precision positioning pipelines. While flex power improves anti-interference capability, the researchers demonstrated that the resulting signal characteristic changes propagate unexpected biases into code measurements, satellite clock offsets, and ionospheric corrections.

The study found that GPS signals remain relatively stable during flex power events, while BeiDou satellites exhibit markedly stronger sensitivity, with noticeable changes in code bias and observation consistency. The researchers proposed a dual-indicator detection approach combining carrier-to-noise density (C/N0) measurements with hardware delay variations, significantly reducing false alarm rates while accurately flagging flex power events across both constellations. They also introduced resilient estimation strategies that dynamically adjust processing models in response to detected events — including new algorithms for code bias correction, satellite clock offset estimation, and phase bias modeling. The work is directly relevant to high-precision applications such as geodetic surveying, PPP, and autonomous navigation, where undetected flex power events could degrade positioning accuracy at exactly the moments when interference resilience is most needed.
