BUSINESS MODEL

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 its advanced trading tier.

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.

OpenAI

OpenAI makes money primarily through API access and subscriptions. The API charges developers per token (roughly per word) for using GPT models in their applications.

ChatGPT Plus costs $20/month for individual users, ChatGPT Team is $25-30/user/month, and ChatGPT Enterprise is custom-priced. Microsoft pays OpenAI licensing fees and also resells OpenAI models through Azure OpenAI Service.

OpenAI's annualised revenue ran past $13 billion during 2025 and kept climbing from there, which is the kind of growth curve that normally only exists in a pitch deck.

HOW THEY STARTED

Coinbase

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.

OpenAI

OpenAI was founded in December 2015 as a nonprofit AI research lab. The founding donors — including Elon Musk, Sam Altman, Peter Thiel, Reid Hoffman, and Jessica Livingston — pledged $1 billion with a mission to build artificial general intelligence (AGI) that would benefit all of humanity.

The idea was that AI was too important and too dangerous to leave in the hands of Google alone.

Sam Altman became chairman while Greg Brockman (former CTO of Stripe) became president. Ilya Sutskever, one of the most respected AI researchers alive, left Google Brain to become chief scientist.

The early team was stacked with world-class researchers who published their work openly — hence "Open" AI.

But AI research turned out to be staggeringly expensive. Training large models required millions of dollars in compute.

In 2019, OpenAI created a "capped-profit" subsidiary — investors could earn up to 100x their money, but profits beyond that would flow to the nonprofit. Microsoft invested $1 billion.

The mission was still to save humanity. The method now involved making a lot of money first.

HOW THEY GREW

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.

OpenAI

ChatGPT's launch in November 2022 was the growth strategy — it just wasn't planned that way. The team expected a modest research preview.

Instead, ChatGPT hit 1 million users in 5 days and 100 million monthly active users in 2 months, making it the fastest-growing consumer application in history. The product went viral because it felt like magic — for the first time, anyone could have a natural conversation with a machine that seemed to understand them.

The Microsoft partnership provided distribution at massive scale. Microsoft integrated OpenAI models into Bing, Office 365 (Copilot), GitHub (Copilot), and Azure.

Overnight, hundreds of millions of Microsoft users had access to OpenAI technology. Microsoft's $13 billion investment was the largest AI bet in history and gave OpenAI nearly unlimited compute.

The API created an ecosystem. Thousands of startups built products on top of OpenAI's models — from customer service bots to coding assistants to content generators.

Each API customer locked themselves into OpenAI's ecosystem, creating switching costs and recurring revenue.

THE HARD PART

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, a 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 SEC dropped the case entirely in February 2025, dismissing it with no penalty and no admission that any token was a security.

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.

OpenAI

The board crisis of November 2023 nearly destroyed the company. The nonprofit board fired Sam Altman as CEO on a Friday, citing a loss of confidence.

Within 48 hours, 95% of employees threatened to quit and follow Altman to Microsoft. By Tuesday, Altman was reinstated and the board was restructured.

The incident exposed the fundamental tension between OpenAI's nonprofit governance and its for-profit ambitions — a tension it finally addressed in late 2025 by restructuring the business as a public benefit corporation sitting under the original nonprofit.

The cost of training frontier models is eye-watering. Each new GPT generation costs hundreds of millions to train.

OpenAI is reportedly spending over $7 billion annually on compute. The company is burning through cash faster than almost any startup in history, which is why it keeps raising at higher and higher valuations.

If revenue growth slows before costs stabilize, the math gets ugly.

Safety concerns are not going away. Multiple prominent researchers have left OpenAI over disagreements about the pace of development versus safety research.

Ilya Sutskever, the chief scientist who was central to the board's decision to fire Altman, left in 2024 to start a safety-focused AI lab. The public debate about whether OpenAI is moving too fast — and whether its safety commitments are genuine — grows louder with every capability improvement.
