RAPT Therapeutics (RAPT) Is Up 8.0% After Index Additions And Trial Progress News Has The Bull Case Changed?

• In December 2025, RAPT Therapeutics, Inc. was added to both the NASDAQ Biotechnology Index and the S&P Biotechnology Select Industry Index, following recent clinical and financing milestones.
• This index inclusion underscores how ozureprubart’s progress, combined with a US$250,000,000 equity raise extending cash runway into mid-2028, is sharpening investor focus on RAPT’s pipeline.
• We’ll now examine how ozureprubart’s Phase 2b food allergy trial clearance shapes RAPT Therapeutics’ investment narrative and future risk profile.

What Is RAPT Therapeutics' Investment Narrative?

To own RAPT Therapeutics today, you need to believe that ozureprubart can convert promising early autoimmune and allergy data into a de-risked, multi-indication asset before the current cash runway and market enthusiasm fade. The recent index additions, alongside the US$250,000,000 raise and Phase 2b food allergy trial initiation, strengthen visibility and reduce near-term financing pressure, which had been a key risk. They also sharpen the near-term catalyst map around food allergy readouts and any move toward later-stage development in chronic spontaneous urticaria. At the same time, RAPT still has no revenue, an ongoing annual loss above US$100,000,000, and is not forecast to be profitable within three years, so the investment case remains highly binary around clinical execution and future partnering or commercialization paths.

However, one near-term overhang may now matter more than the recent index wins. The valuation report we've compiled suggests that RAPT Therapeutics' current price could be inflated.
