The US Federal Communications Commission is preparing to examine a potential 25MHz spectrum auction as SpaceX and Amazon continue their push for satellite broadband dominance, according to a report from The Tech Buzz.

The proposed sale — if it proceeds — would add another batch of mid-band airwaves to the FCC's pipeline at a moment when the two largest commercial satellite-internet operators in the United States are scaling their constellations at record pace. Neither the auction timeline, the price floor, nor the specific band has been disclosed in the early reporting.

Who is competing?

SpaceX operates Starlink, the largest low-earth-orbit (LEO) broadband constellation currently in service, with terminals already shipping to consumers in the US and several overseas markets.

Amazon's Project Kuiper remains in the deployment phase but has secured an FCC authorisation to field a constellation of its own and has booked launch capacity on multiple vehicles to begin populating orbit.

Both operators have spent the past three years courting the FCC for spectrum access, market access modifications and waiver requests, turning the regulator into the principal arena for the commercial contest.

What does 25MHz change?

Mid-band spectrum — the general neighbourhood in which a 25MHz block would sit — is prized for satellite broadband because it balances coverage and throughput more efficiently than the lower bands used by legacy operators. An additional auctionable tranche would give the FCC a fresh tool to allocate capacity to whichever operator, or operators, can demonstrate the most credible deployment plan.

The FCC has not yet tied the proposed auction to any specific licencee or service tier, so the airwaves could in theory flow to SpaceX, Amazon, a smaller LEO entrant, or a terrestrial operator with satellite ambitions.

Where does the regulator stand?

The Commission has accelerated spectrum policy reviews over the past 18 months, leaning toward auction-based allocation rather than administrative assignment for new commercial bands. It has also signalled willingness to revisit the framework under which LEO operators share airwaves with geostationary incumbents, a longstanding friction point in US satellite policy.

For the two flagship LEO operators, any new auction will land on top of an already crowded FCC workload — including pending licence modifications, milestone deadlines tied to constellation build-outs and an ongoing review of orbital debris rules.

What comes next

The Tech Buzz reports that the 25MHz proposal is still in the discussion phase inside the Commission. The next procedural step would typically be a Notice of Proposed Rulemaking, which opens the question to public comment and lays out the auction mechanics, eligible bidders and band plan. Industry filings in those proceedings tend to map directly onto the competitive tactics each operator deploys in the market.

Until the FCC publishes specifics on band, format and timing, both SpaceX and Amazon are likely to keep lobbying the Commission for adjacent spectrum decisions while accelerating constellation launches to strengthen their bargaining position ahead of any auction. The outcome will shape which of the two — or whether a third party — secures the next meaningful block of US satellite capacity.
