Bitcoin replacing SHA-256 by end-of-2026 is all but ruled out. 5% sits at 5%, with $191k in volume and in recent trading has held. The pricing reflects a hard technical reality: protocol changes of this magnitude require near-universal consensus among miners, nodes, and exchanges—a process that has taken years for far simpler upgrades.
Google’s Willow quantum chip announcement in December 2024 did spark legitimate discussion about long-term cryptographic vulnerabilities. But “long-term” is the operative phrase. Bitcoin’s developers have known about quantum risk for over a decade and have already drafted post-quantum migration plans. Implementing one would demand extraordinary coordination across a decentralized network of thousands of independent operators, each with reason to delay a breaking change. A two-year window is implausibly short.
For 5% to move materially higher, you’d need either a concrete cryptographic break against SHA-256 (not a theoretical threat) or a shocking pivot by the Bitcoin core team toward an aggressive fork timeline. Neither is priced in, and neither is evident in current technical roadmaps.
FAQ
What does a 5% price mean?
It is the market-implied probability. A 5% YES price means traders collectively judge the event about 5% likely.
How does this market resolve?
On December 9, Google introduced Willow, a breakthrough state-of-the-art quantum chip. This achievement fueled speculation that Bitcoin's encryption may be vulnerable to quantum computers in the not-so-distant future (see https://www.cryptoglobe.com/latest/2024/12/does-googles-new-quantum-chip-willo
