ETFs and trusts hold record 11.9% of Bitcoin supply in March

ETFs and digital asset trusts now control nearly 12% of Bitcoin’s supply. The market for Bitcoin reaching $100,000 by December 2026 is at 36.5% YES, up slightly from 36% a week ago.

ETFs and DATs accumulated enough Bitcoin to reach that 11.9% threshold, and the $100,000 market has nudged up 0.5 points in response. The steady inflow tracks with growing institutional allocation. The Bitcoin $150,000 market remains at 9.5% YES, suggesting traders still discount extreme price targets heavily.

$1.32 billion flowed into ETFs in March, but the prediction market response has been muted: actual USDC volume sits at $955/day. Moving the $100,000 market 5 percentage points requires $6,646, which points to a relatively stable order book even with the bullish supply data.

What matters here is the institutional commitment these inflows represent. Sustained ETF buying could put a floor under prices and trigger retail buying pressure. With Bitcoin near $69,000, traders betting YES on the $100,000 target by December face a potential 2.74x return. That payout depends on continued ETF inflows and a cooperative macro environment.

Watch for moves from BlackRock and Fidelity specifically. Changes in their allocation pace or new product announcements could shift the $100,000 market meaningfully in either direction.
