  We prove that every symplectic 4-manifold admits a trisection that is
compatible with the symplectic structure in the sense that the symplectic form
induces a Weinstein structure on each of the three sectors of the trisection.
Along the way, we show that a (potentially singular) symplectic braided surface
in $\mathbb{CP}^2$ can be symplectically isotoped into bridge position.
