May Mobility to go public in $1.4B SPAC merger as first pure-play robotaxi stock

May Mobility, an autonomous vehicle developer founded in 2017, is heading to the stock market through a merger with a special purpose acquisition company. According to TechCrunch, the deal with ACP Holdings Acquisition Corp. — a SPAC established by Houston-based investment manager Atlas Credit Partners — values May Mobility at $1.4 billion and could deliver more than $300 million to the company.

How the financing works

The money comes from two streams: a $120 million private investment in public equity and up to $217 million held in the SPAC's trust account. TechCrunch points out a familiar catch with such structures: shareholders of ACP Holdings can redeem their shares when the merger closes, which would shrink the amount of cash that actually lands with May Mobility.

The first pure-play robotaxi listing

Once the merger is complete, May Mobility expects to be the first publicly traded US company devoted entirely to autonomous ride-hailing. TechCrunch notes that this separates it from listed companies whose autonomy programs sit inside broader businesses, such as Tesla, Rivian and Alphabet, which owns Waymo, along with the autonomous trucking firms Aurora and Kodiak. The listing will effectively test whether public market investors want direct exposure to robotaxi economics rather than buying them bundled with a larger operation.

A partnership-first business model

May Mobility's pitch rests on what it describes as an asset-light, partnership-first approach. Rather than owning and operating a fleet itself, the company sells its autonomous vehicles to fleet partners over time while retaining control of remote supervision and software updates. In return, it collects either fixed fees or per-trip licensing fees.

Where the company stands today

May Mobility currently runs autonomous Toyota Siennas in three US locations: Atlanta, through a partnership with Lyft, and the Minnesota cities of Eden Prairie and Grand Rapids. It has recently launched its first trial deployment in Japan, and it plans commercial launches in Arlington, Texas with Uber at the end of 2026 or in early 2027.

The scale is still modest. TechCrunch reports that the company generated roughly $10 million in revenue last year while burning through around $93 million. To date, it has provided more than 550,000 paid autonomous rides covering more than 1 million miles.

What the proceeds are for

The company said the funds will support further research and development, with a particular focus on removing safety drivers from its vehicles, as well as supply chain investments aimed at cutting its bill-of-materials costs. It is also targeting new geographic deployments, some of which it expects to announce before the end of the year.

Why it matters

The listing is a test on two fronts. First, it probes whether public markets still have an appetite for pure-play autonomy ventures, given the sector's earlier SPAC failures and the wide gap between May Mobility's current revenue and its cash burn. Second, it puts the company's asset-light, partnership-driven model up against the capital-intensive, vertically integrated strategy of rivals such as Waymo. If the thesis holds, fleet operators gain a route to offering robotaxis without developing autonomy in-house, and investors get a clearer read on whether that model can sustainably make money.
