Oracle began trading on the New York Stock Exchange on July 15, 2013, and Tesla entered the Nasdaq-100 before that day’s market open as Oracle’s replacement. The events were linked, but they were not the same kind of change: Oracle transferred its stock listing to another exchange, while Tesla—already listed on Nasdaq—was added to an index.
Three dates explain the change
- June 21, 2013: Oracle announced it would transfer its common-stock listing from Nasdaq to the NYSE. The NYSE said Oracle was worth about $156.4 billion and called it the largest market-transfer listing in its history at the time. NYSE’s announcement
- July 8, 2013: Nasdaq announced that Tesla Motors would replace Oracle in the Nasdaq-100 and Nasdaq-100 Equal Weighted Index.
- July 15, 2013: Oracle’s NYSE listing took effect, and Tesla’s index inclusion became effective before the market opened. Nasdaq’s announcement
The announcements came on separate dates, although both changes took effect on July 15. “Oracle gave Tesla its spot” is convenient shorthand, not a literal transfer of membership: Oracle’s move made it ineligible, and Nasdaq named Tesla as the replacement under its index rules.
An exchange is not an index
Nasdaq is a stock exchange where shares can be listed and traded. The Nasdaq-100 is a separate, rules-based index of large non-financial companies listed on Nasdaq, subject to eligibility and selection criteria. Being listed on the exchange does not automatically put a company in the index, and changing exchanges can affect whether a company remains eligible.
Oracle was an existing Nasdaq-100 constituent. Once its shares moved to the NYSE, it no longer met the index’s Nasdaq-listing requirement. Contemporary coverage described relevant criteria that also included size, trading activity and a seasoning period, but the index is governed by its methodology; it is not simply a ranking of the 100 largest companies by market value.

This was not a punishment for Oracle, a sign of financial trouble, or a shutdown of its shares. The company remained publicly traded; only its listing venue changed.
Why Tesla was a notable replacement
Tesla had already been trading on Nasdaq since June 29, 2010. Its 2013 change was index membership, not an exchange move. Nasdaq’s announcement of Tesla’s original listing
When Nasdaq announced the inclusion, it put Tesla’s market capitalization at about $12.8 billion. For a relatively young public company still associated with a niche electric-car business, entry into a prominent large-company index marked a step up in market visibility. It did not mean Tesla was larger than Oracle or that the two companies had competed head-to-head for a slot; Oracle’s departure created a constituent change, and Nasdaq selected Tesla as its replacement.

What the change meant—and what it did not
Membership can make a company more visible to investors and put its shares in the portfolios of funds that track the Nasdaq-100 or benchmark against it. Those funds may need to buy or adjust holdings to reflect index changes, which can create additional trading demand around a change. The size and market effect depend on fund mechanics and other conditions; the inclusion alone does not establish a particular amount of buying or a price move.
Nor was Nasdaq’s decision an investment recommendation. Index membership can confer recognition and affect portfolio mechanics, but it does not guarantee appreciation, improve a company’s underlying business, or predict long-term performance. The evidence for this 2013 event establishes the replacement and the companies’ stated market values at the time, not that Tesla’s share price moved by a particular amount because of it.
For the exchanges, the episode had a competitive and symbolic dimension: the NYSE gained a major technology-company listing, while Nasdaq added a prominent growth company to its flagship index. The NYSE’s description of the transfer emphasized its own brand and technology reach; that is the exchange’s framing, not a confirmed explanation of Oracle’s internal decision. The public announcements establish that Oracle transferred its listing, but do not provide a detailed company rationale. It would be speculation to attribute the move to fees, trading quality, or any particular strategic motive.

The lasting distinction remains straightforward: Oracle is listed on the NYSE under ORCL, while Tesla is listed on Nasdaq under TSLA. Their investor pages confirm those venues: Oracle and Tesla. The 2013 story was a change in Oracle’s exchange listing paired with Tesla’s index inclusion—not Oracle leaving public markets or Tesla newly joining Nasdaq.
