Following a week of surprisingly hot inflation data—with wholesale prices hitting a 6% annual rate—Treasury yields spiked, driving traders to abruptly flip the script and price in a Federal Reserve rate hike by December.

The S&P 500 notched its first-ever close above 7,500 and the Dow reclaimed 50,000 on Thursday, buoyed by optimism surrounding the Trump-Xi summit and strong Cisco earnings. However, the rally stalled Friday as inflation fears returned to Wall Street with a vengeance. Consumer prices rose 3.8% annually, and top economic forecasters now project the inflation rate will reach 6% in the second quarter. Consequently, the 30-year Treasury yield topped 5.12%, and fed funds futures are now pricing in a roughly 51% probability of an interest rate hike by December. Meanwhile, the South Korean Kospi retreated 6% from record highs amid a broad tech sell-off and labor union strikes at Samsung.

DeepSeek slashed its V4 Pro model API pricing to just 25% of its original cost, turning a temporary promotional discount into the permanent standard rate. This aggressive move drops the price to 3 RMB per million input tokens for cache misses and 6 RMB for outputs, making it highly competitive for developers integrating AI into programming tools. This ensures developers can freely deploy the model in various applications without cost concerns, further shaking up the competitive landscape for frontier AI models.

Pardon MIE? Bypassing Apple MIE The standout post today is a brilliant, highly technical teardown of CVE-2026-28952, revealing how researchers bypassed Apple’s heavily marketed Memory Integrity Enforcement (MIE) on the new M5 silicon. It took a three-person team and an AI assistant just five days to go from zero to a root shell. The vulnerability was a classic integer overflow inside _zalloc_ro_mut—the single trusted kernel function allowed to modify read-only zones—and Apple patched it by simply moving an overflow check two instructions earlier. It’s a perfect reminder that hardware-level memory tagging doesn’t protect you if the authorized gatekeeper can be tricked into writing to the wrong slot.

Three years after voters approved the creation of a publicly owned social housing developer, the organization has made its first major move by purchasing the luxury Elara apartment building near Pike Place Market for $60 million. The 150-unit complex in Belltown will be converted into permanently affordable housing, testing a novel social housing model for the United States.

When managing finite LLM context windows in long-running agent sessions, apply a “lazy degradation” strategy that escalates through progressively more disruptive pruning methods—starting with simple payload capping and caching before resorting to expensive LLM-driven summarization.

SpaceX’s colossal Starship V3 successfully executed its first test flight, deploying a payload of mock Starlink satellites before surviving a blazing reentry to splash down in the Indian Ocean. This marks a massive step forward for the economics of orbital logistics and validates the V3 architecture, even though the Super Heavy booster spun out of control and broke apart over the Gulf of Mexico during its descent.

DeepSeek is reportedly negotiating a massive $10 billion funding round that would push its valuation to roughly $45 billion, with founder Liang Wenfeng planning to personally invest up to 20 billion RMB. The move underscores the company’s commitment to pursuing Artificial General Intelligence (AGI) and open-source models rather than rushing short-term commercialization. At the same time, the company announced permanent price cuts for its DeepSeek-V4-Pro API, dropping the cost to a quarter of its original price starting in June to aggressively court developers.

Elon Musk filed to take SpaceX public at a dizzying $1 trillion valuation, despite the company posting nearly $5 billion in losses last year. It is a highly aggressive move that pitches an absurd $28.5 trillion “total addressable market” to retail investors, potentially leaving the public as bagholders if the aerospace company’s astronomical growth projections do not materialize.

Anthropic has officially unseated OpenAI as the world’s most valuable artificial intelligence startup, closing a jaw-dropping $65 billion Series H funding round that catapults its valuation to $965 billion. This historic changing of the guard arrives alongside the launch of Claude Opus 4.8 and a novel “Dynamic Workflows” tool for orchestrating swarms of AI subagents. The massive capital influx proves that explosive enterprise demand is rapidly reshaping the generative AI hierarchy, placing Anthropic squarely in the driver’s seat for the next era of frontier model development.
