April 30 is now a hard date. The SEC’s declaration that Boost Run’s registration statement is effective isn’t a routine administrative step, it’s the milestone that converts a pending transaction into a calendar event. Pulse2 confirmed the declaration, the April 30 extraordinary general meeting of Willow Lane shareholders, and the expected outcome: a combined company renamed Boost Run Inc., trading on Nasdaq under BRUN and BRUNW.
The deal itself has been in motion since September 2025. Boost Run and Willow Lane Acquisition Corp. signed their merger agreement then; what’s happened since is the machinery of a SPAC transaction working through its sequence. SEC effectiveness is typically the last major regulatory gate before the shareholder vote. Barring an unexpected development, April 30 is when investors in Willow Lane vote on whether to approve the combination and take Boost Run public.
What does Boost Run actually do? Per the company’s own description, which is how this should be understood, as company self-characterization rather than independent assessment, it provides GPU and CPU compute, Kubernetes orchestration, and storage infrastructure for enterprise AI workloads. That positions it in the same crowded field as CoreWeave, Lambda Labs, and other specialized AI cloud providers. Its path to Nasdaq via SPAC, rather than a traditional IPO, is worth noting: SPAC transactions have historically offered a faster route to public markets, at the cost of some of the institutional investor validation that comes with a traditional underwritten offering.
The scale difference between Boost Run and the deals dominating this week’s AI infrastructure headlines matters for context. CoreWeave’s reported $6.8 billion Anthropic agreement and the SpaceX/xAI merger at a reported $1.25 trillion represent the hyperscale end of the AI infrastructure market. Boost Run’s SPAC transaction represents something different: a mid-market AI infrastructure provider using the public markets to capitalize its growth, competing for enterprise customers who aren’t buying at the scale of Anthropic or Meta.
Both ends of the market are moving at the same time. That’s the more interesting observation here. The concentration of capital at the hyperscale end doesn’t appear to be squeezing out smaller competitors from accessing public equity markets, at least not yet.
For investors tracking the AI infrastructure public listing wave, April 30 is a date to watch. The AI IPO wave analysis published earlier established the broader pattern; Boost Run’s shareholder vote is a concrete near-term event within it. If the vote passes, BRUN begins trading in the days that follow. No valuation figure for the combined company has been confirmed, that’s standard pre-close territory, so avoid forward earnings or valuation speculation until post-close disclosures.
