May Mobility, the Ann Arbor autonomous ride-hailing company that has already delivered more than 550,000 paid rides, has agreed to go public through a merger with ACP Holdings Acquisition Corp. at a roughly $1.4 billion valuation. The combined company will list on the Nasdaq and describes itself as the first U.S. publicly listed pure-play autonomous ride-hail technology company.
The deal shape
The transaction is expected to generate more than $300 million in proceeds, including a $120 million PIPE and up to $217 million from ACP's trust account, subject to shareholder redemptions. May Mobility posted about $10 million in 2025 revenue against a $93 million cash burn — numbers that only get manageable if the SPAC financing lets the company sustain the deployment ramp its partners are demanding.
The customer story
May's commercial deployments read as a checklist of L4 ride-hailing legitimacy: Lyft in Atlanta, Uber in Arlington, Texas beginning late 2026 or early 2027, plus municipal services in Grand Rapids and Eden Prairie, Minnesota and a trial in Japan. The strategy — plug into existing TNC networks rather than build a consumer app — differentiates it from vertically integrated peers like Waymo and Zoox.
The public-market moment
May's SPAC merger follows recent robotics-and-autonomy public-market moves including PlusAI's trucking SPAC and Agility Robotics' Churchill Capital deal. It also lands the same week Nasdaq-hopeful FPGA maker Altera confidentially filed for an IPO.
Why it matters
May Mobility's model — a pure driving-technology company rather than an operator plus fleet — was easier to fund privately. Going public forces it to price the risk of a business whose upside depends on how quickly Lyft, Uber and city partners can turn pilots into daily-service routes. If the deal clears, it becomes the first pure-play public autonomous-ride-hail stock in the U.S., which is a benchmark other L4 companies will now be measured against.
