FAQ — ASTS vs GSAT vs STARLINK: Who Has the Most Upside? The Fastest Growth? The Wildest Volatility?
Date: 2025-12-15 (paid tier) Tickers: ASTS, GSAT, Starlink (SpaceX-bundled, comparison only) Source: YouTube paid tier
Summary
- Three different bets, three different architectures: ASTS = large phased-array satellites at 530 km, direct-to-phone, 120 Mbps target, 45-60 satellite global constellation. GSAT = 48 satellites at 1,400 km, low/mid-band frequencies (penetration > speed), narrowband, IoT and emergency SOS focus, Apple is a key paying customer. Starlink = 12,000+ small satellites, Ku/Ka high-frequency, requires dish (not phone), home/auto-mount user.
- Why Starlink can't threaten ASTS: physics. Starlink's small satellites lack power for direct-phone connection — they max ~17 Mbps to phone, "future maybe 100 Mbps", but phones can't have larger antennas (cost + radiation safety). ASTS's 65 m² phased-array on the satellite end pushes signal strength so phones can receive it. Direct-to-phone is structurally Starlink's blind spot.
- GSAT's superpower is stability + IoT. FCC just gave them 15 more years on Band 53. Used for: emergency SOS (Apple's iPhone emergency rescue runs on GSAT), asset tracking, IoT remote sensing, drone/equipment telemetry in remote areas. SpaceX is reportedly trying to acquire GSAT because their spectrum conflicts and SpaceX is at $800B valuation while GSAT is only $9B mcap — easy buy.
- Speaker's positions: ASTS = heaviest position, will trade volatility. PL (Planet Labs) second — their image archive is irreplaceable. GSAT third — slow steady 30-50% annual stock appreciation likely (revenue compound 30%, plus margin expansion). Skipping IRDM and (can't invest) Starlink.
- ASTS valuation math: Path to $10B revenue by 2027 = 20x current. But TAM is $1.1T per management — even 1% penetration = $100B revenue, which at 3x PS = $300B mcap (10x current). 2026 is the inflection year — every successful launch raises forward expectations.
Translation
Hello everyone, this is X. Today's paid video covers the ASTS vs GSAT vs Starlink comparison. We covered PL vs BKSY in the last paid video, and the public video had the moats analysis — I won't repeat that here. Today we go deep on these three.
Why include Starlink even though we can't invest in it? Because it's the competitive threat to weigh.
Let me move my avatar so it doesn't block the table.
Architecture comparison
All three are LEO (low-Earth-orbit):
- ASTS: 530 km altitude (similar to Starlink), large satellites
- Starlink: ~12,000-15,000 small satellites
- GSAT: 1,400 km altitude (higher), 48 satellites already deployed, has been operating for years (the most established of the three)
Frequency bands:
- GSAT: L-band, S-band, Band 53 (the gem — 15-year FCC license just renewed). Lower-frequency = better penetration through obstacles, weather, foliage. Lower bandwidth, lower data rate, but stable and low power. Ideal for narrowband applications.
- ASTS: Uses partner telco spectrum (Vodafone, Rakuten, AT&T) — they directly use their carrier partners' existing licensed bands. Very cheap spectrum acquisition, AND zero customer acquisition cost (the carriers' existing customers are ASTS's customers).
- Starlink: Ku/Ka high-frequency. High bandwidth but poor penetration — needs a clear sky and a dish receiver.
Direct-to-device speed comparison
- ASTS (D2D — direct to device, no antenna change): 120 Mbps download to your existing phone
- Starlink with dish: 200-400 Mbps (faster, but only with the dish)
- Starlink direct-to-phone (no dish): 17 Mbps, unstable, "future maybe 100 Mbps"
Why Starlink direct-to-phone won't work: small satellites = small transmit antenna = weak signal at the user's phone. The only way to compensate would be a larger phone antenna — but that's bounded by both cost and radiation safety limits. Phone antennas can't grow much. So the only way to deliver direct-to-phone reliably is bigger satellites with bigger antennas (ASTS's approach).
ASTS deploys ~65 m² phased-array antennas per satellite. That's huge in satellite terms. The big antenna is ASTS's moat.
ASTS also has an architecture-level advantage: fewer satellites = fewer signal hops. Starlink relies on inter-satellite relay links (signal hops between many satellites), introducing failure points. ASTS routes more directly.
GSAT use cases
GSAT's narrowband stability is perfect for:
- Emergency SOS (apple's iPhone uses GSAT)
- Asset tracking (precious cargo, vehicles)
- IoT (Internet of Things — sensor data from remote infrastructure)
- Drone/equipment telemetry
- Remote sensing & remote control
These applications don't need high data rates — they need stable connectivity in places without ground infrastructure, with low power consumption.
This is a growing market. As AI proliferates, as humanity expands beyond visible-line-of-sight infrastructure, more unmanned devices need satellite connectivity. GSAT's TAM is naturally growing — not as flashy as ASTS's direct-to-phone, but sticky and recurring.
SpaceX wants GSAT
SpaceX has been negotiating to acquire GSAT. SpaceX's frequency holdings have conflicts with GSAT's, and acquiring solves that. SpaceX is valued at ~$800B; GSAT's market cap is only $9B. A $9B acquisition for an $800B company is trivially affordable — high probability deal.
The GSAT chairman Munro (who bought the bankrupt company in the early 2000s) and CEO (whose father founded Qualcomm — deep telecom DNA) might extend GSAT's growth and sell at a higher price. So a SpaceX acquisition could send GSAT's stock up another leg when it lands.
ASTS revenue and TAM math
ASTS pitch deck claims a $1.1T TAM. Don't take that literally — that's the total market they could theoretically address.
Revenue split with carrier partners (Vodafone, Rakuten, AT&T): 50/50 on the incremental revenue. This is critical — it's not 50% of the carrier's existing pie. It's 50% of the new fees generated by ASTS coverage in dead zones (rural North America, South America, Australia, ocean/mountain coverage where carriers had no signal).
Customers in cities won't switch to satellite — they have terrestrial. ASTS's revenue comes from dead-zone augmentation.
Penetration math:
- 10% penetration of $1.1T TAM = $110B revenue. At 3x PS → $330B mcap → 10x from current $28.8B
- 1% penetration = $11B revenue. At 3x PS → $33B mcap (close to current)
- 1% penetration in 2-3 years is plausible given the carrier partnerships already locked
Management's 2027 guidance: $1B baseline, $1.5-2B upside revenue. That's already a 20x revenue multiplier from 2025's $40-50M base.
Gross margins after deployment: 70-90%. Once satellites are launched, you can't really maintain them — you just collect subscriptions. Capex is front-loaded in 2025-2026; after that, near-pure profit.
Comparative metrics
| ASTS | GSAT | |
|---|---|---|
| Market cap | $28.8B | $9B (3x ASTS smaller) |
| P/B | 17 | 24 |
| P/S | 738 | 33 |
| Revenue (2025 est.) | $39-50M | $270M |
| Gross margin | Negative (still investing) | 35% |
| Headcount | 580 | 390 |
| Revenue CAGR (recent) | ~1000% | ~30% |
| Debt | $720M | $570M |
| Debt/Equity | 2.5% | 6.3% |
| Leverage (ROE/ROA) | 2x | 4x |
GSAT is mature — already monetizing, decent margins, strong moat, predictable.
ASTS is pre-revenue acceleration — extreme PS now, but if the build succeeds, revenue compounds dramatically.
Ownership
ASTS: - Public/retail: 34% (low, healthy) - Closely held: 50%+ (huge insider commitment) - Top holders: Rakuten 11% (two entities — Investment Mgmt + Group), Vanguard 7%, BlackRock 3.8%, Alphabet (Google) 3%+, AT&T 2%+, Vodafone 1%+ - AND Google has been increasing its position recently - These telco partners' positions effectively reinforce the moat — they're invested in ASTS succeeding
GSAT: - Public/retail: 15% (very low) - Munro (founder): ~60% (was 58%, recently added 2 percentage points) - CEO holds a slice - Heavy founder concentration
ASTS share count expanded from 90M (with 79M free float) to 278M, but free float as % of total has dropped to ~50% — so in proportional terms, more shares are now closely held, not fewer. Insiders' confidence is increasing despite the ATM/convertible raises.
Growth trajectory projections
ASTS: - 2025: ~1000% revenue CAGR (low base) - 2026: ~500% growth (transition year — heavy launch cadence) - 2027: ~300% growth (now substantial base)
To get from $50M (2025) to $1B (2027 guidance) is 20x in 2 years. Decomposed: 5x × 3x = 15x — even slightly ahead of guidance.
2026 = volatile inflection year for ASTS. Every successful launch raises forward expectations and re-rates the stock; every failure or delay sends it down hard.
GSAT: - ~30% revenue CAGR (sustained) - But stock could appreciate 30-50%/year (or more) because as revenue grows on a fixed-cost satellite base, margins expand and cash accumulates — capital-return story compounds. Many mature companies grow 20-30% revenue but stocks compound 50% annually due to the operational leverage on a fixed asset base. - Possibly undervalued. GSAT could be a 30-50% annualized stock for years.
Speaker's portfolio plan
ASTS — heaviest position. Pay attention to entry timing — volatility is high, and add/trim around the swings. Highest expected return of the four, also highest variance.
PL — second priority. Wait for a pullback. PL has more satellites than BKSY, more mature, deeper image archive. Their moat compounds over time. A "scary good" imagery business.
GSAT — third priority. 30-50% annualized base case, plus potential SpaceX acquisition catalyst. Stable.
Skip: IRDM (squeezed by GSAT). Can't invest in Starlink directly.
Final take
ASTS = the moonshot bet — biggest upside, biggest variance, 2026 is execution year.
GSAT = the stable compounder — 30%+ revenue CAGR, expanding margins, possible $20-30B+ acquisition by SpaceX.
Starlink = uninvestable but doesn't kill ASTS.
ASTS has 580 engineers, against SpaceX. They're not really "competing" with SpaceX — they're carving out the direct-to-phone slice that SpaceX architecturally can't address. AT&T, Rakuten, Google, Vodafone — these are sophisticated investors with their own teams who validated ASTS. Their continued holding is a meaningful signal. Failure probability = small. Success probability = large.
OK that's the synthesis. May your performance keep improving. Wishing everyone financial freedom soon. See you next time. Bye-bye.
