Microsoft Scoops Up 700MW Texas Data Center Abandoned by Oracle and OpenAI

Microsoft has agreed to rent a 700-megawatt data center project in Abilene, Texas that developer Crusoe originally built for Oracle and OpenAI — after both companies walked away from negotiations over financing disputes and OpenAI’s shifting capacity requirements. The site sits directly adjacent to Oracle and OpenAI’s flagship Stargate campus, making it a significant acquisition in the heart of the US AI infrastructure corridor. Bloomberg reports Microsoft struck the deal with Crusoe, stepping in as the primary tenant for capacity that would have otherwise sat idle.

The move underscores Microsoft’s aggressive posture on AI infrastructure supply. The company has been systematically expanding its data-center footprint, both through new builds and by absorbing projects that stalled as the Stargate partnership restructured. A 700 MW campus is substantial — comparable to multiple hyperscale facilities — and represents a major addition to Microsoft’s capacity for Azure AI and internal OpenAI-related workloads. Notably, Microsoft retains its own substantial financial relationship with OpenAI, making its expansion next door to Stargate a strategically charged signal about long-term positioning in the AI compute race.

The episode also reveals the volatility underneath the AI data-center boom: even the highest-profile infrastructure commitments — backed by hundreds of billions in pledged Stargate investment — can create excess capacity that quickly migrates to the next-best buyer. Microsoft is positioned to absorb that overflow better than almost any other company.

Apple Launches “Apple Business” Platform With Maps Advertising

Apple introduced Apple Business, a new unified platform that consolidates the company’s enterprise device management and customer-reach tools into a single offering — and quietly baked in the company’s most significant Maps monetization move yet. Beginning this summer in the US and Canada, businesses with a physical location listed on Apple Maps will be able to purchase search ads that appear when users search nearby. The launch follows Bloomberg’s reporting from March 23 that Apple was preparing to bring advertising into Maps for the first time.

Apple framed the ad product with a privacy-first architecture: a user’s location and ad interactions are not linked to their Apple Account, personal data stays on-device, and nothing is shared with advertisers or third parties. Only one ad will appear in any Maps search results, clearly labeled and distinguished by a small blue pin halo. Beyond Maps, Apple Business also delivers an employee directory, business-domain email and calendar accounts, and 5 GB of per-employee iCloud storage — available free in more than 200 countries and regions starting April 14. Apple Business represents a continued diversification of the company’s Services revenue away from the App Store, which faces mounting regulatory pressure globally.

OpenAI Plans to Nearly Double Workforce to 8,000 by End of 2026

OpenAI plans to expand its headcount from roughly 4,500 to 8,000 employees by the end of 2026, according to the Financial Times, concentrating the new hires in product development, engineering, research, and — notably — a new discipline called “technical ambassadorship,” designed to help enterprise customers integrate and maximize OpenAI’s tools. The expansion reflects a deliberate push deeper into the B2B market, where competition with Anthropic, Google, and Microsoft is intensifying as companies shift from AI experimentation to production deployment.

The hiring plan is backed by an ambitious infrastructure goal: OpenAI has committed to reaching 10 gigawatts of computational power by 2030, an ambition that the company acknowledges will require roughly 20% more skilled data-center tradespeople than currently available in the US — driving a parallel partnership with the North America’s Building Trades Unions. The workforce doubling signals that OpenAI is transitioning from a research-led organization into a full-scale enterprise software company, with the revenue expectations and sales-force headcount to match.

ESA’s Celeste LEO-PNT Pathfinder Satellites Poised for Launch Aboard Rocket Lab Electron

Europe is on the cusp of its first dedicated Low Earth Orbit positioning, navigation, and timing demonstration, with the European Space Agency’s Celeste LEO-PNT Pathfinder A satellites scheduled for liftoff no earlier than March 25 aboard Rocket Lab’s Electron rocket on a mission named “Daughter of the Stars” — launched from Rocket Lab’s Māhia Peninsula complex in New Zealand to a 510 km quasi-polar orbit. (The original target was March 24, but Rocket Lab postponed the attempt due to weather conditions.) The two CubeSats — one 12U (~20 kg) and one 16U (~30 kg) — were built by Thales Alenia Space (France) and GMV (Spain) under parallel ESA development contracts and will broadcast signals in L- and S-bands.

Celeste is not a standalone navigation system — it is designed to demonstrate how LEO satellites can complement and augment Galileo and EGNOS, which operate at much higher Medium Earth Orbit altitudes. From a 510 km orbit, LEO satellites move across the sky rapidly, providing much stronger received signal power and faster geometry changes than MEO constellations, which translates into faster convergence times for high-accuracy positioning. The Pathfinder A mission’s primary objectives are to validate the Celeste system definition, test early signal broadcast in operational conditions, and de-risk the technology for the planned 11-satellite full Celeste constellation currently under development.

The broader Celeste architecture is technically ambitious: the full constellation will test signals across S-band (two-way navigation using 5G satellite waveforms for advanced positioning), C-band (additional resilience against jamming and interference), and UHF (enhanced penetration for indoor positioning) — frequency bands that have no precedent in existing civilian satellite navigation services. If the Pathfinder A demonstration succeeds, it could lay the groundwork for a European LEO-PNT layer that gives Galileo users faster, more accurate, and more jamming-resistant positioning in the 2030s — an increasingly critical capability as GNSS interference escalates across conflict zones from Ukraine to the Strait of Hormuz.

Hemisphere GNSS and Calian Launch A65 Antenna With XF Interference Filtering

Hemisphere GNSS and Calian Group announced the joint development of the A65, a next-generation precision GNSS antenna designed as a direct drop-in replacement for Hemisphere’s widely fielded A45 — retaining the same mechanical footprint, connector location, and mounting configuration so that existing agricultural and industrial users can upgrade without any hardware redesign. Announced March 11, the A65 is available now through Hemisphere’s distribution channels, with OEM embedded modules also offered for integrators.

The headline capability is the integration of Calian’s XF Filtering technology directly at the antenna and low-noise amplifier stage — pushing interference mitigation to the earliest point in the signal chain rather than relying solely on receiver-side filtering. The A65 tracks the full multi-constellation suite: GPS L1/L2/L5, Galileo E1/E5/E6, BeiDou B1/B2/B3, GLONASS G1/G2/G3, NavIC L5, QZSS, and L-band correction signals, while reducing power consumption compared to the A45. Ruggedization includes IP69K environmental protection, a high-impact LEXAN radome, 15 kV ESD protection, and a wide operating range of –40°C to +85°C — making it suitable for precision agriculture auto-steer systems, survey rovers, and industrial machines exposed to demanding field conditions.

Key Takeaways

AI infrastructure is consolidating around the most capitalized players: Microsoft absorbing a 700 MW Texas campus abandoned by Oracle and OpenAI illustrates how quickly surplus AI capacity gets redistributed — and how Microsoft’s financial position lets it vacuum up strategic assets as the Stargate partnership evolves.
Europe’s LEO navigation ambitions move from paper to orbit: ESA’s Celeste Pathfinder A launch marks the first real hardware validation of a European LEO-PNT architecture — a critical step toward giving Galileo users faster convergence, stronger signals, and jamming-resilient positioning in a world where GNSS interference is an operational baseline risk.
Interference mitigation is moving up the signal chain: Hemisphere and Calian pushing XF filtering into the antenna stage — rather than the receiver — reflects a broader industry recognition that the RF environment is hostile enough to demand defense at every layer, from antenna to chipset to software.
