AST SpaceMobile's $24 Billion Price Has Already Priced in the 2028 Revenue

AST SpaceMobile (ASTS) is down about half from its high, yet it still carries a $24 billion market price on a company that earned $70.9 million in all of 2025. That gap is the whole story, and it is why the argument about whether revenue will "triple again by 2028" is the wrong question to be asking.

The triple is the easy number. It is already in the price. The only thing that actually matters — the thing that decides whether $24 billion is a rational multiple or a bet with no support — is whether the consumer service that justifies the valuation ever turns on. Right now, it has not.

So here is the flag I am planting, and willing to be graded on: by the full-year 2027 report, expected around March 2028, AST SpaceMobile's revenue will have grown but will not have tripled 2026. The consumer direct-to-cell service, which the company itself still describes as a beta targeted for "later in 2026", will not yet be big enough to change the character of the revenue. I would put the odds of a full 2027 triple below even — closer to 20 to 30 percent — against a stock that behaves as though a multi-billion-dollar company is the base case. That mismatch, not the satellite, is what an investor is actually paying for.

What the revenue actually is

The pitch is simple and the hardware is real. AST builds large satellites that talk directly to ordinary smartphones — no special receiver — to give phone service where cell towers cannot reach. That product is what a $24 billion multiple is a pre-order on. But look at what the company is actually being paid for today, and it is a different animal.

In the second quarter of 2026, AST reported $31.5 million in revenue, just over double the $14.7 million of the first quarter. Of that, $24.4 million was "product" revenue — the sale of ground equipment called gateways — and only $7.1 million was "service" revenue, most of it from U.S. government milestone contracts. Full-year 2025 had the same shape: $44.4 million of product and $26.5 million of service, on $70.9 million total.

That mix matters a great deal, and it is easy to miss. Gateway hardware and government milestone payments are lumpy and project-based: you sell a thing or hit a date, and you get paid. They do not compound the way a phone bill does. The recurring, subscription revenue from ordinary people using their phones — the part that could "triple again" quarter after quarter — is the part that is not yet running. The company's own guidance for all of 2026 is only $150 million to $200 million, and it is weighted toward the fourth quarter. With $46.3 million already booked in the first half, that leaves roughly $104 million to $154 million to be earned in the second half — a real climb, but a climb built on deliveries and government dates, not on a consumer base.

What $24 billion is buying

Now the multiple. At around $62 a share, the $24 billion price is about 210 times trailing sales and still well over 100 times the mid-point of the 2026 guide. No profitable company trades there on its current numbers. The price is not a measurement of AST's business today; it is a measurement of what investors believe the future run-rate will be.

Management has a number for that future. Its chief strategy officer has said the company aims at "approaching a billion of revenue in [its] first year of commercial service", with government work contributing "probably as much as half" of it. So the honest read is this: the stock is not pricing in a $450-to-$600 million 2028 company — the "triple again" figure — so much as a company that must reach something like $1 billion within a few years and then grow from there. The 2028 triple is the modest version of what the price already assumes. If you agree with that larger target, the headline forecast undersells the bet the market has already made.

Two facts make the risk concrete while keeping it bounded. First, the company is losing money — a $230.9 million net loss in the second quarter alone, including a $125.9 million write-down on one lost satellite — and spending heavily to build the constellation, with nearly $980 million of investing cash flow in the first half. Second, that burn is not a solvency problem. AST ended the quarter with $2.7 billion in cash and, after a $1.15 billion convertible note issued in July, more than $3.7 billion on a pro forma basis, plus a backlog of roughly $1.3 billion in contracted revenue and a preliminary Japanese government award (J-LEO) worth up to about a billion in non-dilutive capital. This is a valuation risk — the multiple can fall — not a "does it run out of cash" risk. That distinction is the difference between a stock that halves on disappointment and one that goes to zero.

The clock, and the year behind it

The clock runs on two things, in order. First, the constellation. AST has 13 of its BlueBird satellites in orbit; it needs roughly 25 to give consumers usable half-day coverage, targets about 45 by early 2027, and is building toward a production rate of six satellites a month. Second, the switch: management says a beta service with mobile-network partners is targeted for "later in 2026." Until that switch flips and ordinary subscribers start using the network, the revenue line stays hardware- and government-shaped, no matter how many satellites go up.

Here is the fact that changes how a beginner should read all of this. AST is not the first to do this. T-Mobile's satellite service, built on SpaceX's Starlink, has been commercial — sending texts, photos, and audio over satellite to regular phones — since July 2025, for well over a year before AST's consumer service is even a beta. And SpaceX, which already runs that rival service, is also the launch provider putting AST's satellites up, having carried six of them this year. The technology AST is betting the valuation on is real and shared; what it is betting on is speed, spectrum, and getting to scale first in the consumer space. A rival is already at scale on the messaging side.

The wager and the tripwire

So the falsifiable contract, written down before the next events move:

• Outcome: Full-year 2027 AST revenue grows but does not triple 2026 — it lands below roughly $450 million.
• When it is graded: the full-year 2027 report, expected around March 2028.
• Why I think so: the recurring consumer line is still a beta, and 2026 revenue is still carried by lumpy gateway hardware and government milestone dates, which do not compound.
• The tripwire, and it comes before the deadline: a live, commercial consumer service with measurable recurring revenue must appear within management's own "later in 2026" window. Watch two things in the next two reports — the third quarter (early November 2026) and the first quarter of 2027 (around April to May): does "service" revenue start rising as a share of the total, and is second-half revenue actually building toward the $150-to-$200 million guide?
• What changes my mind: if a live consumer service with real subscription revenue shows up by the first-quarter 2027 report, upgrade the call — the clock has started, a triple becomes plausible, and $24 billion starts to look like a price for a business that is actually forming. If, instead, the third-quarter report shows second-half revenue flatlining against the guide, the problem is smaller and closer than 2028: the 2026 base case itself is in trouble.

The takeaway is a discipline, not a number. When a stock trades at a hundred-plus times its revenue, the interesting question is never the next growth figure; it is the distance between what the price assumes and what the business is actually earning today. For AST, that distance is measured by one concrete, watchable event: an ordinary person's phone, used in a dead zone, paying an ordinary bill. Until you see service revenue — not gateway hardware, not a government milestone — become a meaningful and repeating line in a quarterly report, the "triple again" story is a description of what the price hopes to become, not what the numbers have yet become. That is the gap you are either buying or not.
