## Questions

### Is Spiral a venture fund?

Spiral operates as an independent team within Block, funding open-source bitcoin and Lightning Network developers through grants and sponsorships. It does not take equity positions in for-profit companies and has no external limited partners. The unit distributes its roadmap and grantee list publicly, naming contributors like Matt Corallo and supporting projects such as the Lightning Development Kit.

### How does Tidal fit into Block's investment thesis?

Block acquired a majority stake in Tidal in March 2021 for roughly $300 million in a cash-and-stock deal, with Jay-Z joining Block's board. The acquisition was positioned as a bet on creator tools and artist revenue — not a financial-investment vehicle. A small minority equity investment was reported alongside the deal, but the unit operates as an integrated subsidiary rather than a portfolio company.

### Does Block invest in venture capital funds or only direct deals?

Block's disclosed investment activity centers on direct bitcoin acquisitions, open-source developer funding, and the wholly-owned Tidal subsidiary. No significant fund-of-funds commitments or LP positions in external venture funds have been publicly disclosed. The structure leans heavily toward direct allocation rather than third-party fund commitments.
