Coinbase

Coinbase makes money from transaction fees. Every time someone buys or sells crypto on the platform, Coinbase takes a cut — typically around 1.5% for regular users, lower for high-volume traders on Coinbase Pro.

For a company that processes billions in daily volume, that adds up fast. In the 2021 bull run, Coinbase generated $7.8 billion in revenue.

Beyond trading fees, Coinbase earns revenue from staking (users earn yield on their crypto, Coinbase takes a commission), USDC interest (Coinbase co-created the USDC stablecoin with Circle and earns interest on the reserves), custodial services for institutions, and its cloud platform for developers building on-chain apps.

SpaceX

SpaceX makes money three ways. First, launch services — companies and governments pay SpaceX to put their satellites into orbit.

A Falcon 9 launch costs about $67 million, which undercut the competition by 75% when it debuted. Second, Starlink — SpaceX's own satellite internet constellation, which is now generating over $6 billion in annual revenue from 4+ million subscribers.

Third, government contracts — NASA pays SpaceX to ferry astronauts to the International Space Station and the DoD pays for national security launches.

The secret sauce is reusability. Before SpaceX, every rocket was used once and thrown into the ocean.

SpaceX figured out how to land the first stage booster back on Earth and fly it again. A single Falcon 9 booster has flown over 20 times.

That's like the difference between throwing away an airplane after every flight versus keeping it for decades.

Brian Armstrong was working as a software engineer at Airbnb in 2010 when he read Satoshi Nakamoto's Bitcoin white paper. He became obsessed.

At the time, buying Bitcoin meant navigating sketchy exchanges, wiring money to anonymous accounts, and hoping your coins didn't get stolen. Armstrong thought: this is never going mainstream unless someone makes it dead simple.

In 2012, Armstrong got into Y Combinator and co-founded Coinbase with Fred Ehrsam, a former Goldman Sachs trader. Their pitch was straightforward — be the easiest, safest, most regulated way to buy and sell Bitcoin.

While other crypto exchanges were operating in legal gray areas, Coinbase went out of its way to get money transmitter licenses in every US state. It was slow and expensive, but it meant Coinbase was the one exchange your bank wouldn't block.

The first version was bare-bones. You linked your bank account, bought Bitcoin, and Coinbase held it for you.

That custody model — Coinbase holding your crypto — was controversial with crypto purists who preached "not your keys, not your coins." But for normal people who didn't want to manage private keys, it was exactly what they needed.

SpaceX

In 2001, Elon Musk had just sold PayPal to eBay for $1.5 billion and was sitting on roughly $180 million after taxes. Most people would buy an island.

Musk decided to buy rockets. His original idea was even weirder — he wanted to send a small greenhouse to Mars called "Mars Oasis" to reignite public interest in space exploration.

He flew to Russia three times to buy refurbished ICBMs. The Russians kept raising the price and at one point literally spat on him.

On the flight home from that last failed Russia trip, Musk opened a spreadsheet and started calculating the raw material costs of building a rocket from scratch. He realized the materials were only about 3% of the typical price of a rocket.

The rest was markup, inefficiency, and monopoly pricing by companies like Boeing and Lockheed Martin. He decided to build his own.

SpaceX was founded in June 2002 in a warehouse in El Segundo, California. Musk put in $100 million of his own money.

He hired Tom Mueller, a legendary rocket propulsion engineer who had been building rocket engines in his garage as a hobby. The first rocket, Falcon 1, was supposed to be the cheapest orbital rocket ever built.

It took six years and three spectacular explosions before it finally worked.

Coinbase

Coinbase grew with the Bitcoin price cycle. Every bull run brought a wave of new users who heard about crypto from the news or their friends and Googled "how to buy Bitcoin." Coinbase was almost always the first result.

The company spent heavily on brand advertising including a legendary Super Bowl ad in 2022 that was just a bouncing QR code — it crashed the app from the traffic surge.

The regulatory strategy was the long game. While Binance and FTX grew faster by ignoring regulations, Coinbase spent years and millions getting licensed.

When the regulatory crackdown came, Coinbase was the last exchange standing. Being "the regulated one" went from a competitive disadvantage to the only thing that mattered.

The direct listing in April 2021 was a landmark moment. Coinbase went public via direct listing at a $85 billion valuation — the largest direct listing in history at the time.

It legitimized crypto as an asset class in a way that no Bitcoin price chart ever could.

SpaceX

SpaceX's growth strategy was simple: be cheaper than everyone, then be better than everyone, then be the only option.

They started by undercutting the launch market. The United Launch Alliance (Boeing + Lockheed Martin joint venture) was charging $300-400 million per launch.

SpaceX offered $67 million. Government agencies and commercial satellite companies started lining up.

Reusability was the real game-changer. Landing a rocket booster looked like science fiction when SpaceX first attempted it in 2013.

They failed over and over — spectacular ocean landings, explosions on drone ships, near-misses. But in December 2015, a Falcon 9 first stage landed back at Cape Canaveral.

It was the first time an orbital-class rocket had ever landed after a mission. Now they do it routinely — it's almost boring.

Starlink created a completely new revenue stream. Instead of just launching other people's satellites, SpaceX launched thousands of its own.

By 2024, Starlink had over 4 million subscribers and was generating billions in revenue. It turned SpaceX from a launch company into a telecom company.

Coinbase

The crypto winter of 2022 nearly broke the company. After the collapse of FTX, Luna, and Three Arrows Capital, crypto trading volume fell off a cliff.

Coinbase's revenue dropped from $7.8 billion in 2021 to $3.1 billion in 2022. The stock went from $342 to $35 — an 90% decline.

Armstrong laid off 18% of the company in June 2022 and another 20% in January 2023.

The SEC lawsuit was existential. In June 2023, the SEC sued Coinbase alleging that it operated as an unregistered securities exchange.

The lawsuit claimed that at least 13 crypto assets traded on Coinbase were securities. If the SEC won, it could have fundamentally broken Coinbase's business model.

The case was eventually settled in 2025 with Coinbase paying a $50 million fine but crucially not admitting that any tokens were securities.

Revenue concentration is a structural risk. Coinbase's revenue swings wildly with crypto prices and trading volume.

In bull markets, the company prints money. In bear markets, revenue evaporates.

This makes it nearly impossible to plan long-term or maintain consistent growth — Wall Street hates unpredictability.

SpaceX

The early days nearly killed the company. SpaceX's first three Falcon 1 launches all failed.

The first one in 2006 crashed 25 seconds after liftoff due to a corroded fuel line nut. The second in 2007 reached space but the second stage shut down early.

The third in 2008 failed because the first and second stages collided during separation. Musk had enough money for one more attempt.

If flight four failed, SpaceX was dead.

Flight four worked. On September 28, 2008, Falcon 1 became the first privately developed liquid-fuel rocket to reach orbit.

Musk has said he was so stressed during that period he was throwing up regularly.

The financial pressure was existential. Musk was simultaneously funding Tesla, which was also on the brink of bankruptcy in 2008.

He had to split his last $40 million between the two companies. He borrowed money for rent.

But right at the end of 2008, NASA awarded SpaceX a $1.6 billion contract to resupply the International Space Station. That contract saved the company.

Starship development has been its own saga. The rocket has exploded multiple times during testing.

Each failure costs hundreds of millions. But SpaceX treats failures as data — they move faster by blowing things up and iterating than competitors do by being cautious.

Coinbase

Coinbase is the consumer trading platform — buy, sell, and hold 250+ cryptocurrencies. Coinbase Advanced Trade (formerly Coinbase Pro) is the lower-fee, more sophisticated trading interface.

Coinbase Wallet is a self-custody wallet where users control their own keys. Coinbase Prime is the institutional platform for hedge funds, family offices, and corporations.

Base is Coinbase's own Layer 2 blockchain built on Ethereum, designed for cheap, fast transactions. USDC is the stablecoin Coinbase co-created with Circle — pegged 1:1 to the US dollar with over $30 billion in circulation.

Coinbase Commerce lets businesses accept crypto payments.

SpaceX

Falcon 9 is the workhorse — the most-launched rocket in the world. It carries satellites to orbit and astronauts to the ISS, and the first stage lands itself for reuse.

Falcon Heavy is three Falcon 9 boosters strapped together — the most powerful operational rocket in the world until Starship came along. Dragon is the spacecraft that carries astronauts and cargo to the ISS.

It's the only American vehicle currently flying humans to space. Starlink is the satellite internet service — over 6,000 satellites in orbit delivering broadband to 100+ countries.

Starship is the big one — the tallest and most powerful rocket ever built, designed to carry 100+ people to Mars. It's still in testing but has already completed a full flight.
