Nuburu is trading at $1.05, up 5.90% pre-market; the cause is unclear.

  • No new Nuburu-specific announcement explaining the September 28 pre-market move surfaced in the search.
  • September 22: Nuburu said it had funds to close the planned Tekne acquisition without another capital raise, targeting the first week of October; this predates the move and is not a confirmed catalyst.
  • Broader markets were mixed, with softer futures and technology weakness; no clear same-direction market explanation for the gain emerged.
