For a few days in April, Wall Street decided that Avis Budget Group – the company that rents you a Nissan Versa at the airport counter – was worth more than Ford Motor Company. On April 1, Avis stock opened at $147.52 a share. Three weeks later, it touched $765.94 in intraday trading, a 419 percent run, before closing that day at $713.97. Based on the roughly 35.3 million shares Avis reported outstanding in its most recent annual report, that peak briefly valued the rental-car giant at around $27 billion. A week after that, the stock had collapsed 74.5 percent, closing at $182.005.
A class-action law firm has now sued over what happened in between. But the squeeze itself isn’t the interesting part. The interesting part is what Avis’s own books said the company was worth at the exact moment Wall Street was pricing it like a hot growth stock: negative $3.4 billion.
Read that again. Avis Budget Group finished the first quarter of 2026 with stockholders’ equity attributable to the company of negative $3.415 billion, according to its own SEC filings. Its liabilities exceeded its assets by more than three billion dollars. For one afternoon, traders were paying more for its stock than they were paying for shares of an automaker that actually turns a profit.
That gap is the whole story.
Here’s what actually happened. Pomerantz LLP filed the class action in the U.S. District Court for the Middle District of Florida on behalf of investors who bought, sold, or shorted Avis stock between February 20, 2025 and April 21, 2026. The defendants aren’t Avis executives. They’re Pentwater Capital Management and its founder, Matthew Halbower. Pentwater had built its stake into roughly 51 percent of Avis’s total economic interest, through a mix of stock and cash-settled swaps, by the time the stock started running. The complaint alleges Pentwater’s aggressive buying triggered a short squeeze: bearish traders forced to buy back borrowed shares to cover their positions, pushing the price higher, squeezing even more shorts. It’s the same feedback loop that turned GameStop into a household name in 2021, except this time the household name was a rental-car company most people couldn’t pick out of a lineup of stock tickers.
On April 29, Avis CEO Brian Choi told investors on an earnings call that Pentwater had sold 4.3 million shares between April 22 and 23 for proceeds of $1.75 billion. That’s the dump the lawsuit says crushed the stock for everyone still holding it.
Here’s the detail that deserves more attention than it’s gotten: Avis is not the villain in this lawsuit. It’s arguably a second victim that also happened to profit from the chaos. In June, Avis disclosed that Pentwater agreed to pay the company $650 million to settle a separate claim, one Avis itself brought, under Section 16(b) of the Securities Exchange Act. That’s the so-called short-swing profit rule, a Depression-era provision that forces anyone who owns more than 10 percent of a company’s stock to hand back any profit made from a purchase and a sale inside a six-month window. No intent required. No motive examined. It’s strict liability: prove the math, collect the check. Avis proved the math, and a hedge fund agreed to write one large enough to erase most of a year’s worth of quarterly losses, without renting out a single car.
While all of that was unfolding, Avis’s actual business, the one with the counters and the shuttle buses and the yellow key tags, was in real trouble, and it had nothing to do with hedge funds. In the fourth quarter of 2025, Avis took a $518 million impairment charge after deciding to shorten the useful life of a meaningful chunk of its U.S. electric vehicle fleet. In plain terms, the company told the SEC, in writing, that a lot of its EVs were losing value faster than it had planned for, and it needed to write them down to what they were actually worth. Full-year 2025 net loss came to $995 million on revenue of $11.7 billion. The fleet was the problem, not the customers.
This is not Avis’s first electric-vehicle write-down, and that history is worth sitting with. Rental companies bought heavily into EVs in 2021 and 2022, encouraged by automakers eager to move inventory and by tax incentives that looked better on paper than they turned out to be on a used-car lot. Rental EVs get driven hard, by strangers, with none of the babying a private owner gives a car they intend to keep. They also depend on a resale market that automakers themselves kept undercutting through repeated price cuts, dragging down what every used example was worth. We’ve written before about how fast that kind of depreciation can hit even a brand-new EV. A rental fleet is, underneath the marketing, a leveraged bet on residual value. Avis carried $18.4 billion of vehicle-program debt and $6 billion of corporate debt as of March 31. When the bet on EV residuals went wrong, there wasn’t much room to absorb it.
Even the fix says something. In December, Avis sold a batch of EVs into a joint venture specifically to collect $183 million in cash by monetizing federal tax credits, the commercial clean-vehicle credit, not the retail one, which carries none of the price caps or battery-sourcing rules that apply to ordinary buyers. Large fleet operators can structure their way around restrictions that individual car buyers can’t. That’s not scandalous. It’s just a reminder that the rules bend depending on who’s holding the keys.
None of this is even the first time Avis has played this role. CAR stock was already meme-stock royalty back in 2021, spiking wildly on thin trading for reasons that had almost nothing to do with rental cars. What’s different in 2026 is the size of the number, and the fact that this time, the underlying business had just told federal regulators it was drowning.
That’s the part worth remembering. Wall Street spent three weeks pricing Avis like it was inventing something. Avis spent the same three weeks quietly admitting it couldn’t give its own EVs away.
If you rent cars for a living, insure them, or buy the used ones once a rental company is finished with them, the stock-price theater doesn’t touch you directly. What matters is that one of the country’s largest fleet buyers just told regulators, on the record, that its electric vehicles didn’t hold value the way it assumed, for the second time this decade. That has a way of surfacing later: in what shows up at auction, in what a used EV is worth on a dealer’s lot next year, and in how cautiously the next rental company places its own EV order. Somewhere between the hedge-fund lawsuit and the settlement check, that’s the number worth holding onto. Not $765.94. Not $27 billion. Half a billion dollars in EVs that didn’t hold up, twice.
