Viking Therapeutics $VKTX, Structure Therapeutics $GPCR and Altimmune $ALT: The Next Obesity Drug Race

The obesity-drug market has moved from discovery excitement into commercial combat. That is the central change investors have to absorb. In 2023 and 2024, it was still possible to build a strong biotech story around the idea that a company had an obesity asset with meaningful weight-loss data. In May 2026 that is no longer enough. The benchmark is no longer theoretical. Patients can already get injectable semaglutide, injectable tirzepatide, oral semaglutide and oral orforglipron in the U.S. market, while older weight-management drugs still occupy price-sensitive, generic or non-incretin niches. Novo Nordisk's Wegovy pill was approved in December 2025 as an oral GLP-1 option for weight management, and Eli Lilly's Foundayo, orforglipron, was approved in April 2026 as a once-daily oral GLP-1 pill that Lilly says can be taken without food or water restrictions. Those approvals make the next phase more difficult, but also more valuable, because they validate patient demand for convenience and scale. 3 1 2
