Conducting an IPO allows companies to obtain external capital from investors in exchange for ownership stakes. The capital raised in an IPO is intended to finance the company's economic growth and expansion. A challenge regarding IPOs is the pricing of shares. The study aims to investigate whether there is a relationship between industry affiliation and underpricing in IPOs on Nasdaq Stockholm and First North. The study will also examine whether underpricing differs between IPOs on First North and Nasdaq Stockholm and whether there is a relationship between market conditions and underpricing. The sample of the study consists of 197 companies operating in the Data/IT, Real Estate, Finance, Manufacturing Industry, and Pharmaceutical industries between 2017-2023. The study uses a chi 2 test and t-tests in order to answer the research questions.  The results of the study shows that there is a statistically significant relationship between underpricing and the Swedish stock market. The average underpricing was 8,99% for all IPOs in the sample. Furthermore, the study's results indicate that there is no significant relationship between industry affiliation and underpricing. Future research could examine how IPOs in the selected industries perform over time.
