BARKing mad…
One of the biggest uncertainties in the SpaceX IPO relates to the potential future growth of Starlink’s consumer business, which we discussed in detail in our 65 page report released on Tuesday this week. The most attention-grabbing claim from ARK Invest is that Starlink represents “a business without precedent” because even the early Starship launches of V3 satellites will produce twice as much revenue each year as it costs to manufacture and launch the satellites and acquire customers to fill them.
Those assertions (endorsed by Elon Musk) have led other analysts to predict that “SpaceX will disrupt [the] $1.6 trillion US communications industry” and justify a downgrade of AT&T, while Goldman Sachs is predicting that Starlink will generate $144B in revenue in 2030.
Starlink undoubtedly has a strong platform for growth, although you have to wonder why SpaceX suddenly decided to raise prices in the wake of a disappointing set of Q1 results, where ARPU dropped sharply, and incremental revenue per new subscriber was unsustainably low. That’s not the action of a company that’s looking to compete aggressively against terrestrial telcos and cable companies where multi-year “price lock” guarantees are all the rage.
Some have tried to explain away the price rises, as being “put in place because Starlink was having trouble coping with recent subscriber demand that was driven by price cuts”. But that doesn’t make much sense when Starlink net adds were lower in 2026Q1 (1.4M) than in 2025Q4 (~1.6M) and overall network performance improved continuously throughout 2025. Even potential terminal manufacturing constraints that were pointed out back in February will have been eased by the combination of fewer subscriber adds and increased production (which went from 170K per week at the end of 2025 to 200K per week as reported in the S-1).
[EDIT] And now Starlink has just announced it reached the 12M customer milestone, 111 days after the 10M milestone in February, which is a slightly slower growth rate than the 52 days from 9M to 10M and the 48 days from 8M to 9M customers.
Returning to the mad claims made by ARK, there are multiple errors in the assumptions, including that Starship will be able to launch 60 satellites right away when the roadshow presentation points out that will only be achieved “over time” and most importantly a dramatic underestimate of terminal costs, which at present are multiples of ARK’s assumed $100.
In their recent investor briefing, ST Microelectronics, who make the key chipsets for Starlink, said that “When you look at Ku band user terminal, I think that actually we’re going to soon reach a plateau” in the cost of their chips (which alone cost “a few tens of dollars” before the rest of the manufacturing takes place). At the end of the day, the cost of Starlink terminals is the key barrier to competing with terrestrial, not the cost of bandwidth.
Most egregious of all are ARK’s estimates of revenue per Tbps. If you look at Starlink’s $11.4B of revenues in 2025 and adjust for product revenues and Starshield/Starlink Mobile revenues that aren’t related to Starlink’s broadband business, then you get broadband service revenue in 2025 of about $15M per Tbps. With each extra Starlink V2 mini satellite adding capacity for ~2000 subs around the world, that’s about $62 of revenue per subscriber per month.
But Starlink’s current bandwidth provisioning will have to at least double if it is to compete fully for terrestrial subscribers. If we take the 10x increase in capacity per satellite on V3, but assume that provisioning doubles, that means each V3 satellite will add enough bandwidth to serve 10,000 new subscribers. At the same $62 per sub per month then that’s only $7.5M per Tbps launched. And if you want to compete with terrestrial then the incremental revenue per sub might only be $40 or so (under $5M per Tbps).
In contrast, ARK assumes that the initial Starship launches will generate $17M per Tbps (with a doubling of total system capacity) and $13M per Tbps if 10 times the current capacity is added, i.e. Starlink adds 6000Tbps, which would equate to winning another 100M subscribers with each generating an average of $65/month. That’s just not remotely credible (and incidentally explains why Musk’s daily or hourly launch tempo for Starship simply can’t be achieved based solely on Starlink demand).
Of course once you fix ARK’s underestimated costs and vastly inflated revenue assumptions then Starlink still looks like a very good business, with potential gross margins of around 60%. And Starlink should be able to capture a meaningful number of customers from terrestrial telcos in developed countries (about 100K per month in the US at the moment) if it does decide to price more aggressively at some point in the future. But don’t take these ridiculous assessments, which are being thrown out there to justify an IPO valuation of $1.75T, as saying anything about the reality of Starlink’s business potential and its impact on terrestrial telcos and cable companies. And ask yourself whether you believe Starlink’s next move will be to increase or decrease the price that customers are paying, especially when the prospect of competition from Amazon just moved even further into the future…
