Such a statement would be expected from Airbnb itself - but the prediction comes from one of the leading financial travel analysts in Europe.
In an investor note released last week, Barclays says it forecasts the sharing economy poster-child should double in size over the course of the next 12 months.
Supporting this is what European leisure analyst Vicki Stern estimates is an approximate 10% per year increase in supply in several key markets.
Stern also disagrees with the protestations from a number of hotel groups that impact of Airbnb on their sector is of limited concern.
In the short term, Barclays says, Airbnb is unlikely to have any significant influence on RevPAR growth on the existing players in the leisure hospitality sector.
Only around 10% of Airbnb bookings are estimated to come via business travellers.
Still, risks to hotel groups are likely to be felt only in key cities and in the economy/midscale range of properties.
Barclays singles out Accor as the most exposed hotel group to Airbnb (although the chain has higher leverage financially) with around 9% of of its rooms under threat.
InterContinental Hotels Group is estimated to have exposure in the region of 5% of rooms, Barclays claims.
The note goes on to forecast a massive increase in the number of available rooms over the course of the next few years.
Stern says:
"If this pace is true across the entire Airbnb group it would suggest that the 8 million room nights booked in 2012 could now stand closer to c37 million and this could rise to c129 million room nights booked within the next two years.
"Hence whatever our conclusions on the risks posed by Airbnb today, we should be aware that the threat may be twice as significant within the next year alone, should this pace of growth continue."
A figure in the region of 129 million would see Airbnb overtake IHG within three years, Stern says, although there must be a degree of caution over the forecast given that Airbnb listings are not always available every night in a calendar year.
Still, Airbnb's threat to the wider hotel industry could be twice as significant within one year due to its ongoing growth.
Stern explains:
"Furthermore we estimate that the annual supply growth contribution in key cities is as much as 7-12%, suggesting that the traditional method of looking at supply growth may soon need to also include listings from these sites."
Yet it is not all good news for Airbnb, with Barclays highlighting the worry lines that continue to hang around the brand.
Stern says the company's "fast pace of growth" could decelerate in the coming years, with it being hindered by local regulatory issues (such as New York) and question marks around payment on regional or national tourist taxes (despite recent efforts in Amsterdam).
She says:
"It is possible that increased regulations which limit the number of listings as well as requirements that make hosting more ‘onerous’ either through health and safety requirements or stricter tax requirements could well have an effect on the pace of growth for Airbnb in coming years, albeit the group is already being proactive around reacting to some of these issues and finding solutions."
