Ark Invest built a stake of nearly 3.3 million SpaceX shares worth more than $500 million on the day the company went public in what was described as the largest IPO ever. SpaceX shares were priced at $135 and closed at $160.95, up more than 19% on their first day of trading. Data in daily statements showed Ark likely funded the purchases by trimming other positions, including selling more than $325 million of stock across at least 13 companies around the listing. The ARK Innovation ETF did most of the buying, ending the day with SpaceX representing 3.28% of its portfolio. Ark’s model projects a $2.5 trillion enterprise value for SpaceX by 2030, with a bull-case estimate near $3.1 trillion, compared with a $350 billion private valuation cited for 2024.

Bitcoin June 15–21 Ladder Sees $281,765 Volume: $68K at 69.5% vs $70K at 23.5% as Traders Cluster at the Strike

Polymarket has matched about $281,765 in volume on the Bitcoin price ladder for June 15-21, with positioning clustered around the $68,000 strike. The “↑ 68,000” line implies 69.5% Yes versus 30.5% No, while “↑ 70,000” is far less aggressive at 23.5% Yes and 76.5% No. On the downside rungs, “↓ 64,000” trades at 28.5% Yes and 71.5% No, and the deeper “↓ 60,000” sits at 4.55% Yes versus 95.45% No. The wide spread between $68,000 and $70,000 suggests traders see a moderate upside test as more plausible than a decisive breakout by the June 22, 2026 resolution time.

Watch whether implied odds continue to migrate from the $68,000 rung toward $70,000 and above as volume builds ahead of the June 22, 2026 resolution.
