Cardlytics stock has surged sharply in recent sessions, with Nasdaq data on September 17, 2026 showing a price move of more than 90 percent in 24 hours. A recent 1-for-10 reverse split and a weak 12-month performance frame the risk-reward profile for investors.

Cardlytics stock (ISIN US14161W1053) has seen an abrupt change in its trading profile, with Nasdaq data on September 17, 2026 indicating that the shares recently traded around USD 2.76 after a move of 92.66% over the prior 24 hours and a weekly gain of 193.09%.

Reverse split reshapes share structure

According to Robinhood, Cardlytics implemented a 1-for-10 reverse split for CDLX stock, meaning shareholders now hold 1 share for every 10 shares previously held, with fractional shares retained by the broker.

This corporate action, reported by Robinhood on September 17, 2026, reduces the number of outstanding shares and mechanically lifts the per-share price, a step often used by smaller companies to maintain exchange listing standards and potentially improve the optics of the share price.

Volatile price performance and market metrics

On September 17, 2026, TradingView data for Nasdaq-listed Cardlytics, Inc. common stock under the ticker CDLX showed a current price of USD 2.76, with the platform noting a 92.66% increase over the last 24 hours and a 148.20% rise over the past month.

The same TradingView snapshot indicated that CDLX has gained 24.35% over the past week while still being down 25.54% over the past year, highlighting a highly volatile profile with a stated volatility of 122.47% and a beta of 2.57 relative to the broader market.

In a separate stock comparison updated on September 17, 2026, the analytics portal AltIndex listed Cardlytics with a share price of USD 3.92, a market capitalization of around USD 24 million and a 12-month market cap decline of 68.5% in the marketing and advertising industry, underscoring that the recent rebound follows a prolonged period of weakness.

Fundamental context and recent performance signals

While no fresh quarterly or annual report has surfaced in the latest week-filtered search results, Cardlytics remains positioned in the digital advertising and marketing sector, where performance is often closely tied to consumer spending and the health of advertising budgets across banking and retail partners.

The steep 12-month market cap decline of 68.5% noted by AltIndex as of September 17, 2026 serves as a historical comparison against the current short-term surge of more than 90% in just one day and nearly 150% over the month, suggesting that the stock is still far from recovering its earlier valuation levels despite the recent rally.

For investors, the combination of a small market capitalization around USD 24 million, a high beta of 2.57 and triple-digit volatility implies that CDLX can move quickly in both directions, and that corporate actions like the 1-for-10 reverse split may be part of broader efforts to stabilize the listing and attract new interest in the shares.

Stock remains speculative after sharp rebound

As of September 17, 2026, Cardlytics stock trades on Nasdaq with intraday prices around USD 2.76, reflecting the post-split structure and the recent strong percentage gains but still standing well below earlier levels implied by the historical market cap figures.
