Amazon.com was forced to respond on Friday to a report which claimed that the internet’s most high profile retailer is running out of cash.

The negative publicity caused Amazon’s share price to fall 20% on Friday to an 18 month low. Its market value is approximately $10 billion, one quarter of its market value just six months ago.

Mary Meeker, analyst with investment bankers Morgan Stanley, said that there was “no upside” to Amazon’s revenue estimates.

Wall Street analyst Ravi Suria wrote, “Negative cash flow, poor working capital management, and high debt load in a hyper-competitive environment will put the company under extremely high risk” of running out of cash early next year. He added that the company is also facing significant interest payments for nearly $2 billion in debt.

Amazon has been in debt since 1997, having gone on-line in 1995. Since 1997, it has received about $2.8 billion in funding with revenues of only $2.9 billion. However, the company dismissed the reports of it running out of cash as “pure, unadulterated hogwash” and added that it is “nowhere near running out of cash.”

The negative reports affected the whole US internet share market, with Yahoo, eBay and AOL suffering heavy losses.
