Datavault AI stock, the successor to WiSA Technologies, Inc. (ISIN US97652W1071), continues to trade at depressed levels in 2026 after a series of securities class actions and earlier disclosures about its business prospects led to sharp price declines and ongoing legal uncertainty. As of September 18, 2026, the stock closed at USD 0.15 on Nasdaq, down 76.4 percent from USD 0.65 at the beginning of 2026, underlining how strongly the market has repriced the former WiSA business.

Class actions keep legal risk in focus

On September 20, 2026, shareholder rights law firm Pomerantz LLP announced that it is pursuing a class action lawsuit against Datavault AI Inc. over alleged violations of federal securities laws relating to disclosures between September 4, 2024 and October 30, 2025.The National Law Review reports that the lawsuit, filed in the United States District Court for the Eastern District of Pennsylvania, seeks to recover damages for investors who bought Datavault AI securities during that period and alleges misstatements about the company’s business prospects.

Earlier, on September 21, 2026, another shareholder rights firm reminded investors that a separate class action had already been filed on behalf of Datavault AI shareholders who acquired stock between September 4, 2024 and October 30, 2025.The Globe and Mail notes that this action focuses on alleged misleading statements about Datavault AI’s business and specifically highlights the market reaction on October 31, 2025, when the stock fell USD 0.49 per share, or 19.44 percent, to close at USD 2.03 after investors learned more about the company’s situation.

From WiSA Technologies to Datavault AI

Datavault AI’s current challenges are rooted in its history as WiSA Technologies, a company known for wireless audio technology and the WiSA home-theater standard.MarketBeat describes Datavault AI as formerly operating under the WiSA Technologies name, underscoring how the legacy wireless audio business and subsequent strategic pivot into data and tokenization now coexist with heightened legal scrutiny. For investors who originally entered the stock based on WiSA’s audio technology story, this corporate evolution and the accompanying legal overhang have significantly changed the risk profile.

The same MarketBeat overview shows that Datavault AI shares have dropped from USD 0.6521 at the beginning of 2026 to roughly USD 0.1537 as of mid-September 2026, a decline of 76.4 percent.MarketBeat This quantified comparison illustrates how far the stock has fallen compared with its level at the start of the year and confirms that the market now prices Datavault AI, and thus the former WiSA Technologies equity, at a fraction of its prior value amid concerns about litigation and execution risk.

Market metrics and business implications

Price data from Nasdaq-oriented portals indicate that Datavault AI stock closed at about USD 0.15 on September 18, 2026, with an after-hours indication around USD 0.16 later that day.MarketBeat While detailed intraday highs, lows and 52-week ranges are not fully enumerated in the recent summaries, the combination of a market capitalization figure above USD 10 million referenced in historical WiSA filingsStock Titan and the current low share price suggests that the equity remains highly speculative and sensitive to news. The float mentioned in earlier WiSA-related documentation at around 39.58 million sharesStock Titan also implies that relatively small absolute price moves can translate into noticeable changes in market capitalization.

From an industry perspective, WiSA Technologies had been categorized within semiconductors and related devices.Stock Titan That classification reflects the technology-heavy nature of its wireless audio solutions but now sits alongside Datavault AI’s broader data and tokenization ambitions. The divergence between the original hardware-centered WiSA focus and the current software and data-driven positioning adds another layer of complexity for investors trying to interpret fundamentals and to assess how future revenue and margin trends might look in comparison with the legacy WiSA business.

Investor takeaway and current stock level

For investors looking at WISA’s legacy equity today through the lens of Datavault AI stock, the key takeaway is that legal and strategic uncertainties have materially compressed the valuation. A documented one-day drop of 19.44 percent on October 31, 2025 to a closing price of USD 2.03The Globe and Mail, followed by a further slide to roughly USD 0.15 by September 18, 2026MarketBeat, shows how prolonged the pressure on the former WiSA stock has been. The share now trades well below its 2025 levels, and its 76.4 percent year-to-date decline in 2026 underscores that much of the former WiSA Technologies equity value has been eroded during the transition to Datavault AI amid heightened legal risk.
