Bitmine uplists to NYSE, authorizes $4B buyback, holds 4.8M ETH

Bitmine has moved from NYSE American to the NYSE, holding 4.8 million ETH and authorizing a $4 billion buyback. The Bitcoin $100,000 by December 31, 2026 market on Polymarket sits at 34.5% YES, down from 36% a day ago.

The Bitcoin $100,000 market has $2,613 in daily USDC volume. The Bitcoin $150,000 market sits at 9.5% YES, unchanged over the last 24 hours. The largest single move was a 1-point spike at 2:15 AM, briefly holding at 36%.

Bitmine’s uplisting is the kind of institutional move that traders typically read as bullish for Bitcoin. But the market barely reacted: odds dropped 1.5 points rather than climbing. A $4 billion buyback authorization and 4.8 million ETH on the balance sheet represent real corporate commitment to crypto, yet Polymarket bettors aren’t treating it as a catalyst. The gap between the corporate signal and the market response suggests traders want to see price action, not press releases.

A YES share priced at 35¢ pays $1 if Bitcoin hits $100,000, a 2.86x return. That bet requires believing institutional accumulation will translate into price appreciation over the next eight months.

Watch BlackRock and Fidelity ETF flows for signs of increased institutional buying. Significant net inflows could push these odds higher, while regulatory changes may work against them.
