Note written ·
Price against the kill line
13.3% clear of its kill line on the 13 November 2026 close.
How to read this
This note expects the shares to lag the market, so its kill line sits above the price: a close above the red mark would prove the view wrong. Prices run from low on the left to high on the right. The dot is where the stock closed on 13 November 2026, left of the mark while it is below the line; a dot right of the mark has closed through it.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides
Three months against the kill line
Daily closes, to . Red: the kill line, a daily close above $90.13, on record since 11 November 2026. The shares are down 25.0% since the close; the S&P 500 is down 2.1% over the same sessions. Figures in the note can cover a different window.
Kill line
A daily close above $90.13, which would show the shares leading the S&P 500 again. A third-quarter online marketing decline narrower than the second quarter's 19%, with AI Cloud infrastructure growth at or above 50%, would also show the shares leading.

Catalyst
The business · as of
Baidu runs China's largest search engine and earns most of its money from online marketing sold to advertisers, alongside AI Cloud services sold to businesses, ERNIE AI models and the Apollo Go robotaxi service. Second-quarter 2026 revenue was RMB31.3 billion, down 4% from a year earlier.
What is changing, and what follows · as of
- What is changing now
- On 12 November 2026, at Baidu World, the company said its Kunlunxin M100 inference chip has shipped and launched ERNIE 5.5 Flash Preview at RMB1 per million input tokens, while second-quarter ad revenue fell 19%.
- What follows for the company
- In-house chips lessen dependence on imported hardware for cloud capacity, but low model prices limit revenue per token while shrinking ad revenue, Baidu's largest income line, pressures margins.
- What follows for its customers, suppliers and competitors
- Nvidia (NVDA) faces unapproved large H200 imports into China; Alibaba (BABA) competes in AI cloud and models; Pony AI (PONY) and Waymo owner Alphabet (GOOGL) compete in robotaxis; Lyft (LYFT) partners with Apollo Go.
What the price assumes · as of
No US GAAP quarterly filing gives a valuation line for Baidu. The 13 November 2026 close of $78.14, 52.7% below the 52-week high, rests on second-quarter 2026 revenue of RMB31.3 billion, down 4%; holding it requires AI Cloud infrastructure growth near its 50% pace while online marketing falls no faster than 19%.

The thesis
Baidu's shrinking search advertising still outweighs its fast-growing AI cloud, so the American depositary share (ADS) is more likely to lag the S&P 500 than lead it over the next three months. The third-quarter report before the US open on 16 November 2026 shows whether the advertising decline is narrowing.
The ADS closed at $78.14 on 13 November 2026, down 25.0% over three months and 52.7% below its intraday 52-week high of $165.30 on 22 January 2026. It trades under its 50-day average of $84.30 and its 200-day average of $110.59. The rating is Low because the last reported quarter still showed total revenue falling. The product news from Baidu World on 12 November 2026 does not change the numbers in the quarter about to be reported.
Bullish and bearish views on Baidu, Inc. ADS
The bull case on Baidu, Inc. ADS (BIDU), in brief: cloud growth has reported scale. The bear case: advertising still outweighs cloud.
Bull case
- Cloud growth has reported scale. Baidu's second-quarter 2026 release on 18 August 2026 put AI Cloud infrastructure revenue at RMB7.3 billion, up 50% from a year earlier. The 16 November 2026 report shows whether that pace holds.
- Own chip is now shipping. Baidu said on 12 November 2026 that its Kunlunxin M100 inference chip has shipped, with the flagship M300 expected in 2027. Its own silicon reduces how much cloud capacity depends on imported Nvidia hardware.
- New model and marketplace launched. On 12 November 2026 Baidu unveiled the ERNIE 5.5 Flash Preview model, priced at RMB1 per million input tokens and RMB4 per million output tokens, and said its weights will be open-sourced by 25 November 2026. Its new Token Exchange marketplace handles over 50 million calls and 700 billion tokens a day, according to the company.
- Robotaxi reach is widening. Baidu said on 12 November 2026 that Apollo Go covers 28 cities and has logged over 240 million fully driverless kilometres. Lyft's chief executive described Baidu as one of its autonomous-vehicle partners in comments reported on 6 November 2026.
- The comparison year is weak. Third-quarter 2025 revenue fell 7% to RMB31.2 billion, according to Stocktwits coverage of that report. A flat or rising third quarter in 2026 would be measured against that lower figure.
- Management points to AI profit. Benzinga reported on 1 September 2026 that chief financial officer Henry He expects AI profit could start to match the legacy search business in the near term. That is a management forecast.
- The company is buying its own shares. Baidu's 23 September 2026 disclosure return records 561,800 Hong Kong Class A shares repurchased for HKD49,995,817.96.
Bear case
- Advertising still outweighs cloud. The second-quarter release reported online marketing revenue of RMB13.1 billion, down 19% from a year earlier, and total revenue of RMB31.3 billion, down 4%. Online marketing remained larger than AI Cloud infrastructure.
- Profit missed last quarter. Benzinga's earnings table shows second-quarter 2026 non-GAAP earnings of $1.06 per ADS against an estimate of $1.35, and the ADS fell more than 10% on 18 August 2026, the day of that report.
- Analysts are cutting. Barclays kept Equal-Weight and lowered its target to $80 on 26 October 2026. Deutsche Bank lowered its target the same day, citing profit estimate cuts.
- AI model pricing is low. The RMB1 per million input tokens price for ERNIE 5.5 Flash Preview, announced on 12 November 2026, points to price competition in model services that limits how much revenue each token brings in.
- Chip supply is unresolved. A report on 5 November 2026 said China has not approved large-quantity imports of Nvidia H200 chips. The M300, Baidu's flagship in-house chip, is not due until 2027.
- Robotaxi volume has regulatory friction. On the second-quarter call, Baidu reported 1 million fully driverless rides in the quarter and said ride volume was temporarily affected by operational adjustments in certain domestic cities for regulatory reasons.
- Executive departure. Baidu confirmed on 29 October 2026 that vice president Wu Tian, deputy dean of the Baidu Research Institute, has left. No successor was named.
Price setup
The ADS closed at $81.87 on 6 November 2026 and has drifted lower since, to $78.14 on 13 November 2026. Baidu World did not lift it: the close went from $79.76 on 11 November 2026 to $77.63 on 12 November 2026, the day of the chip and model announcements.
The 52-week closing low is $76.40, set on 30 October 2026; the last close sits less than $2 above it. A close below that level would put the shares at new closing lows for the year. The 50-day average of $84.30 is the nearest level overhead, and the 200-day average of $110.59 is far above. The three-month reference close was $104.12 on 17 August 2026, the session before the second-quarter report.
The report on 16 November 2026 is likely to move the shares sharply. The spread of 63-session returns across US stocks trading at least $5 million a day reached 27% in 2026, so a wide range of outcomes is normal.
Baidu is a foreign private issuer. Its latest annual report is the Form 20-F for the year ended 31 December 2025, filed on 17 March 2026, and its insiders do not file Form 4.
Catalysts ahead
- 16 November 2026: Baidu third-quarter 2026 results before the US open; call at 7:30 AM Eastern. Shows whether online marketing's 19% second-quarter decline narrows while AI Cloud infrastructure keeps growing near 50%, which decides whether cloud can offset advertising.
- ~25 November 2026 (est.): Company deadline to open-source ERNIE 5.5 Flash Preview model weights. Shows whether Baidu's new model reaches developers on the schedule it announced on 12 November 2026.
What would change the view
A daily close above $90.13, which would show the shares leading the S&P 500 again. A third-quarter online marketing decline narrower than the second quarter's 19%, with AI Cloud infrastructure growth at or above 50%, would also show the shares leading.
What it trades with
Baidu trades with other US-listed Chinese internet shares, such as Alibaba, and with Hong Kong technology names; its Hong Kong line, listed alongside the ADS since 1 September 2026, moves in the same sessions. Its cloud business ties to AI-chip supply, so US-China decisions on Nvidia hardware feed through to the shares. Apollo Go puts Baidu alongside Pony AI, Lyft and Waymo in autonomous-driving news, and US political headlines on China, such as the 12 November 2026 report on keeping the House China committee, can move the group together.
