Anduril CEO warns against IPO timing in 'hype cycle'; defense tech builder raises bar on valuations

Anduril CEO Brian Schimpf told CNBC at the Allen & Co. Sun Valley Conference that the drone and AI-weapons company is in no rush to go public, warning against IPO timing during market euphoria. Schimpf defined a successful IPO as one delivering strong investor returns within three years post-launch, not immediate stock pops. He noted that valuations for defense tech are 'crazy high' on expectations of future growth driven by Trump administration military reindustrialization plans and a defense budget on track to hit $1.5 trillion.

Anduril doubled its valuation to $61 billion in May 2026, becoming one of the most richly valued private tech companies. Peer defense startups Shield AI and Saronic also closed large funding rounds earlier this year. Schimpf cautioned that some companies are 'dangerously leading into overvalued territory in a way that could backfire,' suggesting the current market pricing may not be rational. He signaled Anduril would wait for market stability rather than capitalize on current hype—a striking contrast to the IPO rush by OpenAI, Anthropic, and SpaceX.

Meanwhile, the broader defense-tech IPO window remains tepid: SpaceX's June 2026 offering saw shares close at $201.80 on day three but have since dropped ~25% to hover just above the $150 opening price. OpenAI and Anthropic have confidentially filed for IPOs but set no timeline, with some investors skeptical at ~$1 trillion valuations. Architects: Schimpf's restraint signals that even founder-led, well-capitalized AI companies are risk-aware about market cycle timing—a sobering data point if you're evaluating whether defense-tech capex commitments or AI infrastructure spending will stay locked in through a correction.
