Google owner Alphabet has made an offer to acquire US wearable device maker Fitbit, as it eyes a slice of the crowded market for fitness trackers and smartwatches, people familiar with the matter have said.
While Google has joined other major technology companies such as Apple and Samsung Electronics in developing smart phones, it has yet to develop any wearable offerings.
There is no certainty that the negotiations between Google and Fitbit will lead to any deal, the sources said, asking not to be identified because the matter is confidential.
The exact price that Google has offered for Fitbit is also unknown.
Google and Fitbit declined to comment.
Fitbit shares rose 27% on the news, giving the company a market capitalisation of $1.4 billion. Alphabet shares rose 2% to $1,293.49 last night.
A deal for Fitbit would come as its dominant share of the fitness tracking sector continues to be chipped away by cheaper offerings from companies such as China's Huawei Technologies and Xiaomi Corp.
Fitbit's fitness trackers monitor users' daily steps, calories burned and distance traveled. They also measure floors climbed, sleep duration and quality, and heart rate.
Fitbit, which helped pioneer the wearable devices craze, has been partnering with health insurers and has been making tuck-in acquisitions in the healthcare market, as part of efforts to diversify its revenue stream.
Analysts have said that much of the company's value may now lie in its health data.
Fitbit cut its 2019 revenue forecast in July, blaming disappointing sales of its newly launched cheapest smartwatch Versa Lite.
The watch is priced at $160, compared with $200 for the full version. It can track workouts and heart rate but lacks features such as the ability to store music directly.
In August, Fitbit said it had signed a contract with the Singapore government to provide fitness trackers and services in a health programme it said could reach up to 1 million users.
Fitbit in August also launched its latest smartwatch, Versa 2, adding Amazon.com voice assistant Alexa, online payments and music storage to the device's capabilities.
Fitbit would not be the first deal that Google would be carrying out in the wearables space.
Fossil Group said in January it would sell its intellectual property related to smartwatch technology under development to Google for $40m. Google's plans for these assets are not clear.
