Carr's $100bn spectrum target is the entry fee

The FCC's next round of spectrum auctions could raise up to $100 billion over the next couple of years, Chair Brendan Carr told Reuters, a figure that belongs on the cost side of the wireless build. Data Center Dynamics reports the slate runs to four sales, starting with Upper C-Band next year, up to 160MHz on the block and the gavel due by July; three further auctions have been formally notified, with a goal of finishing them by the end of 2028.

The schedule is news only because Washington had none. Congress let the FCC's auction authority lapse in March 2023 — the first such lapse ever, according to the report — and the commission regained it last year, so a regulator that went roughly three years without selling a license now intends to hold four auctions in about two. Carr's account that the market's appetite has changed from a couple of years ago reads less like a boast than a capacity plan.

Carr locates the demand in the Big 3 — AT&T, Verizon and T-Mobile — bidding for the same blocks, which is what makes a spectrum sale a contest rather than a shopping trip, but the bid list is no longer only theirs. SpaceX has kept bidding for spectrum to build out Starlink, and the $17 billion of spectrum it acquired from EchoStar last year puts a satellite operator at the table alongside carriers that have to fund licenses and construction from a single capital plan. Satellite bidders raise the clearing price, which is the input that competes most directly with radios, fiber backhaul, small cells and the power contracts underneath them.

That is what the tower and fiber owners who carry the construction risk should be underwriting: spectrum is the cheapest component of a wireless network and the one that must be bought before a single site is touched; the license is the asset, and the steel is a consequence of it. As this publication has argued, consent is the new capital across digital infrastructure, and spectrum happens to be the one consent queue Washington still runs against a published timetable—the most predictable input in the asset class, with the three-year lapse as the reminder that even federal consent can go dark for reasons no developer controls.

The $100 billion is a cost the physical layer will have to absorb, and towers should be underwritten on that basis. If the Big 3 plus a satellite bidder push proceeds toward the top of Carr's range, what follows is built with what is left after the Treasury takes its share, which pushes tenant commitments later and thins per-site economics on the builds that do proceed. Slippage in the three follow-on auctions, past the 2028 target, would help builders by spreading the license bill across more budget years. Upper C-Band is due by July, and the clearing price there, not the headline, is the number that tells tower and fiber owners whether the next wireless construction cycle arrives funded or deferred.
