Kook's Weekly - September 15
Kook · Unidentified guest
In this solo 'Kook's Weekly' recap (Sept 15, 2025), Kook covers a rare Sunday AST SpaceMobile tweet showing what looks like native iOS integration with a satellite indicator on an iPhone.
He also covers ongoing uncertainty over the FM-1/ISRO launch timing and the stock's pullback from ~$60 to the high-$30s. The dominant topic is SpaceX's $19 billion purchase of 50 MHz of S-band spectrum from EchoStar.
Kook argues the market misread that deal as bearish for AST, when he believes it is actually a defensive, multi-year-lagging move by SpaceX that validates AST's cheaper, already-secured Ligado L-band position.
He also runs through Golden Dome/government developments, the Ligado confirmation hearing, FirstNet, a new Homestead, Florida facility, and a critique of Starlink's underlying unit economics. He discloses several of his own non-ASTS investments (DMYY, MFI, VFC, Weight Watchers).

Key Takeaways
- Kook hosts this solo 'Kook's Weekly' recap; Anpanman is referenced only as an outside contributor (screen grabs, spectrum analysis, a UBS update, and an X Spaces session), not as a co-host in this episode.
- AST SpaceMobile posted an unusual Sunday tweet/video appearing to show a satellite connectivity indicator integrated directly into iOS on an iPhone (4 bars of signal plus a 'sat' icon), which Kook and others read as a hint of deeper native Apple integration, though no formal Apple partnership announcement has occurred.
- AST SpaceMobile's stock fell from roughly $60.95 in July 2025 to about $38.37 by mid-September, which Kook attributes mainly to seasonal weakness, delayed launch expectations, and market overreaction to SpaceX's spectrum news rather than any fundamental deterioration.
- SpaceX agreed to buy 50 MHz of US-only S-band spectrum from EchoStar (Charlie Ergen) for about $19 billion total ($17B cash plus stock, plus $2B of interest relief); the spectrum is not yet supported by any handset, requires new chipsets and satellites, and (per SpaceX) would take about two years to deploy, with the deal not closing until 2027.
- Kook argues the SpaceX/EchoStar deal is a defensive admission that SpaceX lacked direct-to-device spectrum, and contrasts the ~$19B price for unsupported S-band spectrum with AST's roughly $2 billion (his own rough estimate) all-in cost for 45 MHz of already-usable Ligado L-band spectrum.
- Kook estimates AST SpaceMobile could have generally available commercial service with continuous coverage as early as 2026, versus SpaceX's spectrum deal not closing until 2027 and (worst case) not deploying until 2028 or later, implying roughly a 3-year head start, and argues no competitor is likely to have a comparable custom low-power ASIC chip within 3-5 years.
- The Ligado bankruptcy plan confirmation hearing is scheduled for September 22, 2025, with FCC approval of the spectrum transaction as the next step after that.
- FirstNet executives said new technology, described as a 'differentiated product in partnership with AST SpaceMobile,' is planned to roll out next year (2026); pricing/contract structure (lump sum vs. usage-based, against roughly 6 million FirstNet subscribers) is not yet known.
- Golden Dome program lead Michael Gitlin was expected to reveal his plan this week, and Kook had heard it may reach President Trump's desk soon; separately, the Missile Defense Agency published a Golden Dome RFP with bidder offers due October 10, 2025, a timeline Kook flags as seemingly inconsistent with an imminent plan reveal.
- AST SpaceMobile is building a new manufacturing/engineering facility in Homestead, Florida expected to employ around 60 people, intended partly as a recruiting hub outside Midland, alongside a disclosed roughly $200,000 government incentive package.
- Kook questions whether Starlink is fundamentally a good business today, estimating (his own rough math) roughly $5 billion/year of retail-priced satellite-replacement capex (about $2.5B assuming a 50% launch margin) just to hold its constellation flat, given its low-orbit satellites deorbit quickly.
- Tim Ferriss published an article speculating the SpaceX spectrum deal was partly meant to pressure Apple; Elon Musk publicly responded that 'pretty much everything is wrong' in the article.
- Kook clarified he has not diversified away from AST SpaceMobile as his primary position, but disclosed smaller separate holdings in DMYY (a SPAC targeting a Horizon Quantum merger), MFI (a shell company he believes is headed for a reverse merger), VFC, and a new Weight Watchers distressed-debt position.
Detailed Discussion16 topics
Sunday tweet and possible Apple/iOS integration
4
-
AST SpaceMobile posted an unusual Sunday tweet/video (rare timing for the company) showing what appears to be a sat-to-cell indicator integrated into iOS on an iPhone, with 4 bars of cellular service plus a separate 'sat' indicator in the status bar; Anpanman captured the screen grab that circulated.
-
Kook speculates this could reflect deeper native integration beyond AST's baseline 'no special hardware needed' compatibility, pointing to the AT&T/Vodafone/Google side letter and language in the Ligado bankruptcy documents that reportedly contemplates Apple-device integration on the L-band spectrum, with 'real economics tied to that.'
-
Kook is unsure whether the demoed connection ran over AST's own proprietary test network/core (for testing purposes) or through an actual MNO core; he notes AST previously confirmed (with AT&T corroboration) making calls directly through an MNO core, but his 'strong suspicion' is that this particular clip used AST's own test core rather than a live MNO core, though he says he doesn't know for sure.
-
Kook thinks it's 'very reasonable' that a formal Apple/AST partnership story (e.g., in a major outlet) eventually surfaces, similar to how Apple's cooperation with Starlink/T-Mobile became public, and expects Apple to likewise 'accommodate' AT&T and Verizon; he flags a hypothetical tweet from an analyst he calls Katsy/Cathie describing an 'iOS 26 development beta with native FaceTime app doing livestream over Bluebird satellite' as a first take that hasn't been confirmed.
ISRO / FM-1 launch timing
3
-
The chairman of ISRO reportedly put out a slide listing a 'Bluebird mission target' of September 2025, which conflicts with AST's more recently understood launch window of Q1 2026 or a November-to-January window; Kook says he has 'no idea' when the ISRO launch will actually occur and treats this as an unresolved, conflicting signal.
-
Kook separately notes there is 'strong hope' AST's next launch (FM-1) will fly on a SpaceX Falcon 9, with a lower (and seemingly declining) chance it ends up on Blue Origin's New Glenn 2, but no confirmed date exists yet; he says he has asked industry contacts but has no firm answer.
-
Kook notes the episode falls around the one-year anniversary of the original Block 1 BlueBird launch (September 2024), remarking that many in the community did not expect a full year to pass before the next satellite launch.
Stock price action
3
-
Citing a recap by contributor @TutuFly (auto-translated from Spanish), the stock ran up to roughly $60.95 in July 2025 before falling to about $38.37 by mid-September, amid typically weak August/September seasonality.
-
Kook and @TutuFly attribute the drop mainly to the market conflating normal seasonal weakness with the delayed satellite launch and the SpaceX spectrum-purchase headline, rather than any real change in AST's fundamentals; Kook notes 'the stock price writes the news.'
-
Kook points out that even an investor who bought AST SpaceMobile stock near a 2024 high of about $40 is still roughly breakeven or better, framing recent volatility as noise for long-term holders.
SpaceX's $19 billion EchoStar spectrum deal
2
-
SpaceX agreed to buy 50 MHz of S-band spectrum from EchoStar (Charlie Ergen) for a total of about $19 billion — roughly $17 billion in cash plus stock, plus about $2 billion of interest relief. The spectrum covers the US only, is not currently supported by any handset (requires new chipsets), requires new satellites, and per SpaceX would take about two years to deploy.
-
Kook believes actual deployment will take considerably longer than SpaceX's stated ~2-year timeline, noting the deal itself won't even close until 2027, and full commercial deployment would still require Apple/Google/Qualcomm-ecosystem chipset support plus FCC approval — putting real availability at 2028 or later in his 'worst case' framing.
Kook's 'defensive, not offensive' thesis on the SpaceX deal
3
-
Kook's own (self-described 'unpopular') read, published as his own tweet, is that the spectrum purchase was a defensive move by SpaceX rather than evidence of market dominance — arguing Starlink began as a byproduct business to fill spare Falcon 9 launch capacity, uses Ka/Ku-band frequencies that don't require AST's large phased arrays, and was never structured for the MNO partnerships that direct-to-device requires.
-
Prompted with 'Why?' in response to Kook's claim that SpaceX wasn't equipped to tackle the direct-to-device market at inception.
-
Kook argues Elon Musk historically avoids partnerships (citing that Tesla never partnered with GM) and doubts Musk would want to work through AT&T's and Verizon's technical/MNO processes; Musk has said he intends to compete as his own MNO, while also acknowledging existing MNOs 'aren't going anywhere' because of their spectrum holdings.
Competitive timeline: ASTS vs. SpaceX direct-to-device
3
-
Kook estimates AST SpaceMobile could have a generally available commercial service with continuous coverage in key markets as early as 2026, versus SpaceX's spectrum deal not closing until 2027 and (his worst-case assumption) not deploying until 2028+ — implying at least a 3-year AST head start even before considering chip development.
-
Kook, citing an informal conversation with a friend who is a principal engineer at Nvidia, argues that a custom low-power ASIC (like AST's AST5000) is essential to make satellite-to-unmodified-phone beamforming power-efficient, and believes no competitor — including SpaceX — is likely to have a comparable ASIC on the market in under 3 to 5 years.
-
Kook also flags unresolved technical questions for SpaceX around beamforming, Doppler-effect compensation, and MNO-core network integration, noting AST's own carrier integration reportedly took 'hundreds of thousands of hours' of engineering effort to get working.
Outside commentary and analysis
4
-
Kook relays that 'Professor' Kevin Mack characterized the SpaceX/EchoStar spectrum deal as 'largely a non-event' and expects the direct-to-device market to ultimately support three global players, a framing Kook says he agrees with.
-
Briefly affirms ('Yeah') during Kook's summary of Kevin Mack's take.
-
Kook cites an essay from a contributor called Jagaloon arguing that AST's structural advantages built over the past year (its own spectrum, partner relationships) outweigh the week's negative headlines.
-
Anpanman published spectrum-focused analysis and a UBS research update this week, and separately hosted a well-attended X Spaces session reacting to the SpaceX spectrum news.
Elon Musk on All-In and 'X Phone' speculation
3
-
On the All-In podcast, when a co-host remarked that 'Verizon kind of sucks,' Elon Musk reportedly nodded along; Kook doubts this plays well in Verizon's boardroom and thinks it reduces the odds of a SpaceX-Verizon commercial relationship.
-
Kook speculates Musk's real long-term ambition behind the spectrum purchase could be building his own 'X Phone' to bypass Apple's app-store/gatekeeper model, reading Musk's past dismissive comments about an 'X phone' as effectively signaling one is coming.
-
Kook argues this dynamic could push Apple and Google toward supporting AST SpaceMobile as the 'carrier neutral' — and, in his new framing, 'handset-manufacturer neutral' — option, since AST has no plan to build its own phone, unlike a hypothetical SpaceX-built device that would threaten Apple/Google's ecosystems directly.
Spectrum price comparison: Ligado (AST) vs. EchoStar (SpaceX)
3
-
Kook estimates (his own rough, unverified math) that AST paid roughly $2 billion all-in for 45 MHz of L-band spectrum — about $550 million upfront plus roughly $200+ million of stock plus $80 million/year of lease payments capitalized — versus SpaceX's $19 billion for 50 MHz of S-band spectrum that isn't yet supported by any handset.
-
Confirms the SpaceX spectrum in question is S-band ('Of S-band').
-
Kook relays an analysis (attributed to 'Katsy'/Cathie) explaining the price gap: EchoStar's S-band has viable alternative terrestrial/other-constellation uses, while Ligado's L-band was largely 'orphaned' (blocked from terrestrial use due to interference, previously tied mainly to Inmarsat's narrowband maritime use); L-band's lower frequency also requires roughly 30% wider antenna element spacing than S-band (about 10cm vs. 7cm half-wavelength), meaning about 69% more physical antenna area for equivalent gain.
AT&T and FirstNet commentary
3
-
AT&T CEO John Stankey, speaking at a Goldman Sachs conference, said AT&T had considered whether someone would try to become a 4th MNO with the new spectrum and effectively responded 'good luck,' noting that operating a mobile carrier is far more capital-intensive than simply 'hanging 50,000 towers.'
-
FirstNet executives publicly said new technology is planned to roll out 'next year' (2026) as a 'differentiated product in partnership with AST SpaceMobile.'
-
Kook doesn't yet know whether the FirstNet commercial structure will be a lump-sum contract or usage-based against FirstNet's roughly 6 million subscribers, and speculates pricing could land in a $10-$20/month range.
Golden Dome and government/defense
5
-
Golden Dome program lead Michael Gitlin was expected to reveal his plan this week, and Kook says he has heard the plan may reach President Trump's desk 'tomorrow,' though he flags this as something he 'heard' rather than confirmed.
-
The Missile Defense Agency published a Golden Dome request for proposals with bidder offers due October 10, 2025 — a timeline Kook notes seems inconsistent with Gitlin supposedly revealing a plan the same week; he says he cannot resolve the apparent conflict.
-
Briefly affirms ('Yep') during Kook's reading of the Golden Dome RFP timeline.
-
Kook doesn't know what contractual form AST's Golden Dome-related work might take (e.g., selling satellites outright per unit vs. an ongoing service/software contract), but argues AST's vertically integrated, non-radiation-hardened manufacturing approach (avoiding costs he estimates run up to 20x higher for satellites built to survive 15 years) could let it sell satellites at roughly half the price of traditional 'job shop' competitors, plus attach recurring service revenue.
-
FCC Chairman Brendan Carr continues to publicly describe the space-based connectivity market as a 'game changer' in a US-versus-China framing; Kook also cites unnamed government contacts describing Space Force as a top government priority.
Ligado spectrum deal status
1
-
The Ligado bankruptcy plan confirmation hearing is scheduled for September 22, 2025; assuming the plan is confirmed on schedule, the next remaining step toward AST's long-term L-band access is FCC approval of the spectrum transaction.
Manufacturing: Homestead, Florida facility
2
-
AST SpaceMobile is building out a new facility in Homestead, Florida expected to employ around 60 people; Kook mentions an unspecified setback (possibly related to space constraints) and notes bears mocked a disclosed roughly $200,000 government incentive package as small.
-
Kook argues the Homestead facility's importance may be underestimated, since it could serve as a key recruiting tool for top engineering talent outside Midland — he notes, by comparison, that BlueWalker 3 was reportedly built by a core team of only about 12 people, calling this his own speculation.
Is Starlink actually a good business? (Kook's analysis)
3
-
Kook's own opportunity-cost estimate: Starlink must replace roughly 5 satellites per day (about a full Falcon 9 launch every 5 days) just to hold its constellation flat because its satellites fly low (around 300km) and deorbit quickly, implying roughly $5 billion/year of maintenance capex at retail launch pricing, or about $2.5 billion/year assuming (his own guess of) a 50% launch margin.
-
Kook questions whether Starlink is fundamentally a good business today, citing historical ARPU north of $100/month (now being cut), terminal subsidies functioning as a customer-acquisition cost, and 'double churn' (subscriber churn plus satellite-fleet churn), and suggests its economics may depend heavily on an unproven transition to Starship and V3 satellites.
-
Kook raises a possible regulatory tail risk for SpaceX: given the pace and scale of its LEO launches, international regulators (e.g., the ITU) could eventually restrict further megaconstellation buildout on orbital-congestion/re-entry-pollution grounds, potentially favoring AST's much smaller (~100-satellite) constellation design.
Tim Ferriss article and Elon Musk's response
1
-
Tim Ferriss published an article (which Kook says he didn't personally find inflammatory) speculating the SpaceX/EchoStar spectrum purchase was partly designed to pressure Apple over spectrum cooperation; Elon Musk publicly responded that 'pretty much everything is wrong' in the article.
Kook's personal (non-ASTS) portfolio disclosures
4
-
Kook clarified a prior comment was misread as him diversifying away from AST SpaceMobile; he says that isn't true and the money involved is separate, much smaller capital.
-
Kook holds a position in DMYY, speculating it will complete a merger with Horizon Quantum (a company building tools to translate conventional code into quantum-ready code, led by CEO John Fitzgerald), calling it a 'medium conviction' investment partly held as 'schmuck insurance' after missing IonQ.
-
Kook also holds a position in MFI, a corporate shell he believes with high confidence is being positioned for a reverse-merger/IPO vehicle by an individual he describes as a major Bitcoin holder possibly linked to the HBX crypto exchange.
-
Kook continues to hold VFC ('great and not great') and disclosed a new position in Weight Watchers, describing it as a distressed-debt situation he is tracking via its bankruptcy docket after a weak recent quarter, rather than a fully published investment thesis yet.

Open Questions7
-
Was the iPhone sat-to-cell demo shown in AST's Sunday video run over AST's own proprietary test network/core, or through an actual MNO (AT&T/Verizon) core?
-
Will there be a formal public announcement of an Apple/AST SpaceMobile partnership, and when?
-
Will AST's FM-1 launch fly on ISRO, SpaceX Falcon 9, or (less likely) Blue Origin New Glenn 2, and on what date?
-
What contractual structure would AST SpaceMobile's Golden Dome-related work take — selling satellites outright versus an ongoing service/software contract — and will AST even be included in the Golden Dome program?
-
Will the FirstNet contract with AST be structured as a lump sum or a usage-based fee tied to FirstNet's roughly 6 million subscribers, and at what price point?
-
What obligations, if any, do Apple and Qualcomm have to support the new EchoStar spectrum SpaceX purchased, and could that be used as leverage to get Apple to cooperate with AST/Ligado's L-band spectrum instead?
-
Is Starlink actually a good business on a standalone basis today, given its high satellite-replacement capex and reliance on price-subsidized terminals, absent a successful transition to Starship and V3 satellites?
