Gravitational waves (GWs) provide a window into the early Universe and a direct probe of the epoch prior to Big Bang nucleosynthesis, which is otherwise difficult to access. In this talk, I will discuss recent progress towards accurately predicting and detecting the stochastic gravitational wave background produced at first-order cosmological phase transitions involving physics beyond the Standard Model (BSM). I will present updated prospects for probing various BSM scenarios at the future space-based interferometer LISA and highlight recent progress towards a nonperturbative determination of the phase transition parameters entering the GW spectrum. I will also comment on other promising BSM sources of gravitational radiation and complementarity with collider searches.
