The trading week ending June 5 was one of the busiest of the year for IPOs and earnings. 72 companies reported quarterly results, while at least five new IPOs began trading — headlined by Quantinuum (quantum computing) and INNIO (industrial energy equipment).

This Week's IPOs

Quantinuum (NYSE: QNT) debuted on the Nasdaq Thursday at $53–$55 per share, raising approximately $1.43 billion. The quantum computing hardware and software company now trades around $56, above its IPO range, with a market cap of roughly $1.76 billion.

INNIO (NYSE: INIO) was the week's largest IPO, raising $1.91 billion at $24–$27 per share. The Austrian industrial company, which makes power generators under the Jenbacher and Waukesha brands, trades at around $32 with a market cap of approximately $24 billion.

Sunshine Silver Mining & Refining (NYSE: SSMR) raised $300 million at $13.50–$16.50 per share. The company is developing the Sunshine silver mine in Idaho. The stock trades near $14.

Liftoff Mobile (Nasdaq: LFTO) raised $399 million at $20–$22 per share. The AI-powered mobile advertising platform trades around $27 — well above its IPO price — with a market cap of about $4.5 billion.

Applied Aerospace & Defense (NYSE: AADX) raised $633.75 million in a Tuesday IPO at $18–$21 per share. The company manufactures aerospace and defense subsystems. The stock trades near $17.50.

SpaceX: The Biggest IPO in History

The week's biggest story comes next week: SpaceX (Nasdaq: SPCX) is set to go public on June 12 at $135 per share, targeting a $75 billion raise — by far the largest IPO in Wall Street history. To put that in perspective, Alibaba's 2014 IPO ($25 billion) was previously the record. SpaceX's offering would be three times larger.

Earnings: A Quiet Week for Big Tech

72 earnings reports crossed the tape this week, with Tuesday (17 reports) and Wednesday (24 reports) being the busiest sessions. Among mega-cap tech, current valuation multiples remain moderate by historical standards:

  • NVIDIA (NVDA) — $205/share, P/E 31, EPS $6.52
  • Meta Platforms (META) — $593/share, P/E 21.5, EPS $27.52
  • Microsoft (MSFT) — $416/share, P/E 24.8, EPS $16.79
  • Amazon (AMZN) — $246/share, P/E 31.6, EPS $7.77
  • Apple (AAPL) — $307/share, P/E 37.2, EPS $8.27
  • Tesla (TSLA) — $391/share, P/E 358.7, EPS $1.09

Why It Matters

This week marks a renewed acceleration in the IPO market after a relatively quiet start to 2026. The strong debuts of Quantinuum and INNIO, combined with the massive SpaceX IPO on the horizon, signal robust investor appetite for new issuance — especially in technology and space-related sectors.

The Bottom Line

This week's IPOs — particularly Quantinuum and INNIO — saw strong demand and are trading above their offer prices, a healthy signal for the IPO pipeline heading deeper into June. SpaceX is the headline event everyone is watching, and it will test whether the market can absorb an offering of unprecedented size. On the earnings side, the coming week is expected to be quieter.
