Morgan Stanley’s Bitcoin ETF sees $34M trading volume on debut

Morgan Stanley’s MSBT Bitcoin ETF traded $34 million on its first day, and the Bitcoin $100,000 by year-end market on Polymarket now sits at 34.5% YES, up from 30% a week ago.

Market reaction

The ETF carries a 0.14% expense ratio, undercutting competitors and giving Morgan Stanley’s advisor network a cheaper on-ramp to Bitcoin exposure. The sub-market for $150,000 by year-end is at 9.5% YES.

Why it matters

Trading volume in these prediction markets is still thin: $2,613 daily for the $100,000 target and $877 for the $150,000 target. The largest price move in the past 24 hours was a 1-point spike for both sub-markets, which suggests traders are positioning cautiously rather than making large directional bets. The ETF launch follows a period of significant outflows across Bitcoin ETFs.

What to watch

At 34.5¢, a YES share on Bitcoin hitting $100,000 by year-end pays $1 if it resolves, a 2.9x return. The key variables are continued ETF inflows and whether other large allocators follow Morgan Stanley’s move. Watch for inflow data and announcements from BlackRock and MicroStrategy in particular.
