# Every distribution platform follows a four-step cycle; cycles are getting shorter

## Claim
Every dominant distribution platform, Facebook, Google, iOS, LinkedIn, Twitter, now ChatGPT, moves through a predictable four-step cycle: competition for category, moat identification, open platform with free distribution, and lock-down with monetization. Early movers in step two get free escape velocity; late entrants get crushed. Cycles are accelerating.

## Claim
Every dominant distribution platform moves through four steps, category competition, moat identification, open platform, lock-down, and the only durable advantage is recognising the cycle and moving into the open phase before competitors do.

## Mechanism
A new platform must seed an ecosystem to win category dominance. During seeding, third-party distribution is effectively free, that is the open phase. Once the platform identifies its moat (network effects, data lock-in), it monetizes by absorbing the highest-value use cases and suppressing organic distribution. Operators who built their flywheel during the open phase have escape velocity by the time the close happens; late entrants face paid-only distribution against incumbents with audiences.

## Conditions
Holds when:
- A genuinely new distribution surface emerges (a platform, not a feature).
- Operator capital and decision speed are aligned to ride the open phase.
- The product has loops that compound during open distribution (network effects, content, data).

Fails when:
- The "platform" is actually a feature that does not develop network effects (most marketing-channel hype falls here).
- Open-phase entry is too early, there is no audience yet to harvest.
- The operator's product does not benefit from rapid scale (pure consulting, low-throughput services).

## Evidence
> "If you don't do it, your competitors are going to go to the new platform and your customer expectations change. There is no opting out of the game."

> "The cycles seem to be getting shorter and shorter so you actually have a smaller amount of time to play the game."

Examples Balfour cites: Facebook (social games, ~5 year cycle), Google (SEO → ads, ~10+ years), iOS (App Store → ATT), LinkedIn (organic feed → paid promotion). ChatGPT's window may be 1–2 years. Zynga rode the Facebook open phase to 100x growth; many missed it and were killed. Cursor beat GitHub Copilot in nine months by moving onto the AI-IDE channel faster.

## Signals
- A platform shifts from open API and free third-party distribution to paywalls, rate-limits, or feed-algorithm changes that suppress organic.
- Native first-party apps from the platform start absorbing third-party use cases.
- Acquisition CPMs rise sharply as the platform monetizes.
- Cohorts who entered during the open phase show step-change retention versus late entrants.

## Counter-evidence
The framework is descriptive and pattern-matched; not every new surface follows it. Some "platforms" (e.g., NFTs, certain crypto channels) never reach a real open phase. Operators who chase every cycle suffer from attention fragmentation; the discipline to *not* enter a fake cycle matters as much as the speed to enter a real one.
