Musk Cleared to Acquire Mesh Optical, a SpaceX Alumni Startup

The FTC granted early termination of its antitrust review for Elon Musk's acquisition of Mesh Optical Technologies on June 25, 2026, according to Bloomberg. The regulator determined the deal raised no significant competition concerns, fast-tracking clearance under transaction number 20261601.

Mesh was founded by former SpaceX engineers and builds optical transceivers for AI data centers. Its flagship product, the Alpha C1, operates at 1.6 terabits per second, converting electrical signals into light for connections between servers and GPUs. Conventional copper-based interconnects inside data centers burn significant power and introduce latency; optical transceivers replace those copper links with light and reportedly deliver better power efficiency and lower latency. The company emerged from stealth in February 2026 after closing a $50 million Series A led by Thrive Capital, with Also Capital and Banner VC participating. Financial terms of the acquisition have not been disclosed.

The founding team reportedly built optical communications for Starlink before launching Mesh. Bringing that capability in-house, rather than sourcing from an established transceiver vendor, fits the pattern of vertical integration into AI compute infrastructure.

What the reporting does not give you is whether Mesh's technology will remain available to third-party data center operators or become exclusive to Musk-affiliated infrastructure. That question matters for any lab building its own GPU clusters: if a high-throughput optical interconnect supplier is captured by one actor, it changes the supply calculus. The acquisition price is undisclosed, so the premium over the Series A valuation, if any, remains unknown.
