Morgan Stanley Bitcoin ETF sees $30.6M inflows on first day

Morgan Stanley’s Bitcoin ETF (MSBT) launched on April 8, 2026, collecting $30.6 million in inflows on its first trading day. On Polymarket, Bitcoin reaching $100,000 by December 31, 2026, is at 34% YES, down from 36% yesterday.

## Market reaction

The MSBT launch followed recent SEC approvals for spot Bitcoin ETFs, opening the door to more institutional participation. The $100,000 sub-market dipped 2 points, possibly reflecting profit-taking after the ETF’s initial excitement. The $150,000 market is unchanged at 9.5% YES.

## Why it matters

Volume data tells a more specific story. The $100,000 market trades $2,613 in USDC daily, with $2,908 needed to shift odds by 5 points. The $150,000 market is thinner: $877 in daily trading and $792 to move 5 points. A 1-point spike appeared at 2:15 AM, but large moves have been rare, pointing to a cautious market.

Morgan Stanley entering the spot Bitcoin ETF space is a concrete institutional commitment, but the 2-point dip in the $100,000 odds suggests traders want more than first-day inflows to justify higher prices. At 34¢, a YES share pays $1 if Bitcoin hits $100,000 by year-end, a 2.94x return. That payout makes sense only if you expect continued institutional adoption or favorable regulatory shifts to push Bitcoin higher over the remaining months of 2026.

## What to watch

Further ETF launches from other Wall Street firms, SEC rulings under Paul Atkins, and Bitcoin accumulation trends by institutional holders. Any of these could move the $100,000 market meaningfully in either direction.
