ACV Auctions (NYSE: ACVA) exploded about +44% to trade near $10.50 after Copart (NASDAQ: CPRT) agreed to buy the whole company for cash. The stock closed at just $7.22 the day before. This isn't an earnings pop or a hot data point — it's a takeover, and takeovers move a stock differently. Here's what actually happened and why it matters.

What happened

Copart signed a definitive agreement to acquire ACV for $10.50 a share in cash — a ~45% premium and about $1.9 billion in total, Copart's biggest-ever deal. It's structured as a tender offer (Copart asks shareholders to hand in their shares at $10.50), expected to close by year-end 2026, after which ACV becomes an independent Copart subsidiary run by its current team.

Because the offer is cash, the stock didn't drift — it snapped straight up to just under the deal price. From here ACVA basically stops trading on its business and starts trading on one question: will the deal close? The small gap left below $10.50 is the arbitrage spread — the sliver a trader pockets if it completes on schedule.

Why Copart wanted it

Copart is the king of salvage — it auctions wrecked and totaled cars, mostly for insurance companies. ACV is a different animal: a digital dealer-to-dealer marketplace for whole, drivable used cars. Buying ACV pushes Copart out of its insurance-totaled niche and into the far bigger dealer-wholesale flow. ACV already runs marketplace GMV of about $2.7 billion a quarter and moved 211,472 vehicles in Q2 2026 — instant scale in a channel Copart didn't have.

Is it expensive?

ACV isn't profitable, so there's no P/E to quote — it guided to a 2026 net loss of $50–54 million. On sales it's cleaner: the ~$1.9B price against 2026 revenue guidance of $845–855 million works out to roughly 2.2x forward sales. Compare that to the obvious listed peer, OPENLANE (NYSE: KAR) — the other digital wholesale platform — which trades near a $3.28B market cap on $1.93B of trailing revenue, about 1.5x sales. So Copart is paying a richer multiple than KAR fetches in the open market. That fits: you pay up to take out a faster grower, and the 45% premium is the sweetener that gets a board to say yes.

The business

ACV runs online wholesale auctions where used-car dealers buy and sell from each other, plus the services around it — vehicle inspections (its detailed condition reports are the real selling point), valuation data, transport, and financing. Its take rate is lean: fees run about $360 per vehicle, roughly half what Manheim or KAR charge. That price edge is exactly why a bigger player wanted it.

Who it touches

• OPENLANE (KAR) — the direct digital rival now faces an ACV backed by Copart's balance sheet and insurer relationships. The fight for dealer wholesale just got heavier.
• Manheim (Cox Automotive) — the roughly 42%-share incumbent of physical whole-car auctions now stares at a bigger combined online challenger.
• Carvana — bought ADESA's US physical auction sites in 2022; the remarketing map keeps redrawing around it.
• Copart shareholders — management calls the deal neutral to EPS in year one and accretive after, so near-term this is a growth bet, not an earnings kicker.

What to watch

It's a cash tender offer, so ACVA's upside is effectively capped at $10.50 unless a rival bidder appears — unlikely at this premium. The real risk is regulatory: folding a salvage giant and a fast-growing dealer platform under one roof can invite an antitrust look, and any slip past year-end widens the arb spread. Keep an eye on the tender's minimum-shares threshold and whether regulators ask a second time for information.
