A researcher has broken a 15-bit elliptic curve key, a new step in quantum computing capability. The Ethereum $10,000 by 2026 market on Polymarket sits at 4% YES, unchanged over the past week.
Both Ethereum and Bitcoin rely on elliptic curve cryptography (ECC) for transaction security, and an estimated $600 billion in Bitcoin sits in addresses with exposed public keys. Ethereum’s $10,000 by 2026 remains at 4%, and Bitcoin’s all-time high by December 2026 is at 18.5% YES.
The Bitcoin term structure shows traders pricing more risk into late 2026 than the near term. The September 30 market is at 10.5% YES, while December 31 jumps to 18.5% YES, an 8-percentage-point gap that implies traders expect late-2026 catalysts or resolutions.
Ethereum’s market shows minimal activity, with a combined daily USDC trade volume of $14, and moving the price requires $1,052, pointing to a thin order book vulnerable to swings from larger trades. Bitcoin markets have more liquidity with $29,669 in face value traded, though actual USDC volumes are significantly lower.
A 15-bit key is far from the 256-bit keys used in production, but the direction of progress matters. If ECC were compromised at scale, confidence in cryptocurrency security would erode. A YES share on Ethereum reaching $10,000 trades at 4¢, offering a 25x return if realized. That bet requires Ethereum to both survive the quantum threat and achieve major price appreciation.
Watch for further quantum computing results, responses from Vitalik Buterin and the Ethereum Foundation on post-quantum migration plans, and any regulatory or institutional announcements about cryptocurrency security standards.
