Xingsi Semiconductor becomes $10B+ satellite-chip unicorn in third raise of 2026
What's the deal? Xingsi Semiconductor, a Shanghai-based maker of 5G/6G satellite communication baseband chips, has closed a strategic industrial funding round, becoming a unicorn valued at more than US$1.38B. It is the company's third disclosed raise of 2026, less than six months after a US$206.3M round in February 2026.

What's the endgame? Xingsi builds the baseband chips that let terminals connect to low-Earth-orbit satellites — widely seen as the hardest chip in wireless. Its line-up spans baseband SoCs for phone-direct bands (L, S/C, S/S) and broadband terminals (Ku, Ka), and it has completed validation with leading handset makers, automakers, and communications module vendors.
The product angle: At MWC Shanghai 2026, Xingsi launched the CM7620 broadband satellite communications module, extending its reach across chip, module, and terminal. That followed a March 2026 strategic partnership with ZTE to develop 6G non-terrestrial-network satellite internet.
Why now? China's commercial space sector is accelerating. On 10 July 2026, the country carried out its first controlled recovery of a rocket first stage, a step toward cheaper, more frequent launches. Xingsi is the only 6G satellite internet baseband chip company in the national commercial aerospace innovation consortium.
The track record: Founded about six years ago, Xingsi validated its technology in the lab in 2023, ran ground field tests in 2024, and in 2025 completed what it calls a world-first phone-to-satellite broadband HD video call based on the 3GPP 5G NTN standard. The company reports a 100% first-tape-out success rate on its baseband chips.
What could go wrong? Satellite baseband chips face steep technical hurdles — large Doppler shifts, long delays, and high path loss — and demand long validation cycles. On-orbit testing windows last only minutes a day, raising development cost and time.
The signal: Repeat bets from top investors point to capital moving early on the next-generation communications value chain. As commercial space and 6G advance, the baseband chip is emerging as a decisive component in terminal competitiveness — and one of the hardest to replace.
