Tesla's addition to the S&P 500 will witness an unprecedented $80 billion trade by the end of the session on Friday, as per market reports. Tesla is poised to become the most valuable company ever added to the main Wall Street index on Monday.

The Elon Musk company's shares will then account for over 1 percent of the index, Reuters reported. Tesla shares have surged about 60 percent since mid-November.

Tesla's addition to the index will force index-tracking funds to buy over $80 billion worth of Tesla shares by the end of Friday's session so their portfolios correctly reflect the index, as per S&P Dow Jones Indices. "Index managers will need to sell a large position across the other S&P 500 constituents in order to fund the addition of TSLA, which could lead to substantial impact across the entire index," Virtu ITG Canada's head of index research, Ivan Cajic, wrote in a report this week.

Actively managed funds that benchmark their performance against the S&P 500, many of which until now have avoided investing in one of Wall Street's most controversial stocks, will also be forced to decide whether to own Tesla.

Tesla is by far the most traded stock by value on Wall Street, with $18 billion worth of its shares exchanged on average in each session over the past 12 months, easily beating Apple, in second place with average daily trades of $14 billion, according to Refinitiv.

A blockbuster quarterly report in July cleared a major hurdle related to profitability that had prevented Tesla's inclusion in the S&P 500.

About a fifth of Tesla's shares are closely held by Musk, the chief executive, and other insiders. Since the S&P 500 is weighted by the amount of companies' shares actually available on the stock market, Tesla's influence within the benchmark will be slightly diminished compared to its overall value.
