The 2021 initial public offering (IPO) market launched into the year with a record start, with the most special purpose acquisition companies going public in a single week. Last week saw the introduction of 28 SPACs raising over $6.7 billion. For comparison, it took five months in 2020 for the same amount of SPACs to price, and 2020 was a hot market year for blank check companies.

Last week also saw the listing of two traditional IPOs, with both raising a combined total of $459 million, giving the new year's market a healthy start. Filing activity was also raised, with many would-be 2020 IPOs looking to get into the public market as soon as possible since the market settled following the December blockbuster debuts of Airbnb (ABNB  ) and DoorDash (DASH  ).

Cullinan Management, Inc. (CGEM  ) raised the largest offering last week, pricing its upsized offering above the upwardly revised range at $21 per share to raise $250 million at a $953 million market capitalization. The oncology-focused biotech is developing a portfolio of therapies and its lead candidate is currently in Phase I/II clinical trials. The stock finished the week up 42%.

Gracell Biotechnologies Inc. (GRCL  ) followed, pricing its offering above the range at $19 per share to raise $209 million at a $1.3 billion market cap. The Chinese oncology-focused biotech has currently two treatment candidates in Phase I clinical trials, with data expected by the second half of 2021 and 2022, respectively. The stock finished the week strong, rising 32% from its pricing.
