The Los Angeles Times reported that the social networking site will get about $25m from the two deals, which is enough to make the company profitable.
Twitter is said to have made $15m from the deal that puts its status updates on Google's search page, and $10m from Microsoft's Bing deal.
While Twitter's exponential user growth surprised most, monetising the site has appeared to be a slower process. Speculation over where revenue will come from has ranged from paid-for business accounts to advertising revenue.
None of the companies involved would confirm the figures, but the contracts themselves highlight the increasing value of the millions of updates from Twitter users every day.
