A developer posted to Hacker News on August 28th unveiling prmpt.cash, a platform that rewards users with cryptocurrency for simply using Claude Code. The service works by delivering non-intrusive targeted ads while you code, then splitting the advertising revenue back to users in BTC, SOL, or—notably—Anthropic's pre-IPO stock through PreStocks on Solana.

How Passive Earnings Work

The mechanic is straightforward: install or integrate prmpt.cash with your Claude Code workflow, and the platform serves contextual advertisements tailored to your coding sessions. Instead of advertising revenue going solely to the platform operator, users receive a cut in their chosen cryptocurrency. The developer claims ads are "highly targeted" to minimize disruption while maximizing relevance to developers' actual work.

The Anthropic Pre-IPO Angle

What makes prmpt.cash stand out is its payout flexibility. Beyond traditional crypto options like Bitcoin and Solana, users can opt to receive compensation in Anthropic pre-IPO stock via PreStocks—a mechanism that allows holding equity positions before a company goes public. For developers heavily invested in the AI ecosystem or confident about Anthropic's future, this could be a strategic way to accumulate exposure to the company's growth potential without direct purchasing power.

Why This Matters for Developer Economics

The intersection of crypto incentives and developer tooling isn't new—Gitcoin grants and various token-gated communities have explored similar territory. But prmpt.cash takes a different angle by embedding rewards directly into an existing workflow rather than asking developers to participate in separate ecosystems. If the ad targeting proves valuable enough to generate meaningful revenue, it could represent a sustainable model for compensating AI tool users.

Key Takeaways

  • Users earn BTC, SOL, or Anthropic pre-IPO stock through Claude Code usage
  • Revenue comes from non-intrusive targeted advertisements served during coding sessions
  • Pre-IPO Anthropic stock is accessible via PreStocks on Solana blockchain
  • Platform launched August 28, 2026 on Hacker News (score: 8)

The Bottom Line

This is a clever idea with real execution risk—ad revenue models are notoriously volatile, and whether targeted ads in coding environments generate enough to make payouts worthwhile remains unproven. But the Anthropic pre-IPO option? That's the kind of asymmetric bet that could make early adopters very happy if Anthropic's eventual IPO mirrors OpenAI or Scale AI valuations.
