BlackRock buys $600M in Bitcoin amid $612M ETF inflows

BlackRock purchased $600 million in Bitcoin as its ETF recorded $612 million in inflows. The Polymarket contract for Bitcoin reaching $100,000 by year-end is at 35.5% YES.

Market reaction

The $100,000 market sits at 35.5%, with $5,971 in USDC traded daily. The $150,000 target is at 9.5% YES, up from 8% a week ago. The $100,000 contract dropped 3 points earlier, though the scale of institutional inflows could push it back up.

Why it matters

$612 million in single-day ETF inflows is a direct measure of institutional demand. That money is entering a spot Bitcoin product, not futures or derivatives, which means actual BTC is being purchased and held. The size of BlackRock’s $600 million buy specifically signals that the largest asset manager in the world is increasing its Bitcoin exposure at current prices.

What to watch

Order book depth shows it takes $4,757 to move the $100,000 market by 5 points, which is moderate liquidity. The largest single move in the last 24 hours was 3 percentage points, meaning the market reacts to significant trades but isn’t easily pushed by small orders.

A YES share at 36¢ pays $1 if Bitcoin hits $100,000, a 2.78x return. The bet depends on continued institutional buying and no resolution to the geopolitical tensions currently driving demand for non-sovereign assets.

Key catalysts: further ETF inflow data, SEC regulatory announcements, and any shift toward a dovish Fed stance.
