Will Bitcoin replace SHA-256 before 2027?
5%
Real price history (past month), from Polymarket. Down-sampled to 24 points.
What the market is pricing
The market is priced at single-digit, unlikely odds for a Yes outcome, and has remained unchanged over the past week. This reflects very low market confidence that Bitcoin will replace SHA-256 within the timeframe, despite recent developments in quantum computing raising theoretical concerns about encryption vulnerabilities.
How this market resolves
This market resolves Yes if Bitcoin adopts a replacement for its SHA-256 cryptographic hash function before December 31, 2026. The resolution criteria and specific mechanism for determining adoption are not fully stated in the provided description.

What could move it
- An official Bitcoin protocol upgrade decision would be the primary driver—any formal proposal or community consensus to switch cryptographic standards could shift odds materially.
- Thin time remains before the end of 2026; as the deadline approaches without concrete movement toward a SHA-256 replacement, odds are unlikely to rise significantly.
