Anthropic has released a Research Preview that allows Claude to directly control the user's computer – opening apps, navigating browsers, filling out spreadsheets. The tweet achieved nearly 100,000 likes and is thus the most discussed AI event of the week. This feature positions Claude as a direct competitor to Operator-like systems and shifts competition from chatbots to autonomous desktop agents.

The US Department of Defense officially elevates Palantir's Maven AI system to 'Program of Record' and integrates it permanently into combat operations. This is the most far-reaching institutional AI weapons contract to date and gives Palantir structural monopoly status in military AI. At the same time, it became known that Anthropic rejected a similar Pentagon contract – which OpenAI subsequently took on.

Mistral released Mistral Small 4 with 119 billion parameters, 256k context window, and configurable reasoning under Apache 2.0 – 40% faster and 3x more throughput than its predecessor. Simultaneously, a strategic partnership with NVIDIA was announced for co-development of open-source frontier models. This move solidifies Mistral's position as the leading open-source alternative to proprietary US models, particularly for European enterprise customers.

PwC US CEO Paul Griggs warned internally that partners who are not 'paranoid AI-first' will be replaced – one of the clearest statements from a Big Four leader on AI transformation. This signals a turning point: AI is no longer a pilot project, but a mandatory requirement for career continuity in professional services. Together with the NVIDIA study documenting widespread AI deployments in law, finance, and administration, a picture of industry-wide restructuring emerges.

On Polymarket, the market bets with 97% probability that Anthropic will be the holder of the best AI model by end of March 2026 – a historically high figure for a single provider. For June, Anthropic also leads at 57%, Google follows with 26%, OpenAI at only 10%. This market assessment aligns with engagement data from the week and reflects that Claude's new computer-control feature has significantly shifted the perception of model strength.
