IBM Anchored Research Triangle Park for 60 Years. It's Packing Up the Same Year the Region Pulled In $10.8 Billion.

North Carolina's 1950s economy ran on tobacco, textiles, and furniture. In 1954 the state's own Research Commission concluded its most underused asset was three research universities -- Duke, UNC-Chapel Hill, and NC State -- sitting an hour apart, and Research Triangle Park opened in 1959 as a deliberate, state-organized bet on that idea. Nothing else landed for half a decade until IBM arrived in 1965 with a 400-acre research facility built for its System/360 mainframe project, becoming the Park's anchor tenant for the next sixty years and eventually its largest employer, at times topping 10,000 workers on one site. In 2025, IBM is consolidating that same workforce into a single leased building and exploring options for its original campus, down to roughly 8,000 employees across the Triangle. The same year, North Carolina pulled in $10.8 billion in life sciences manufacturing investment -- Novo Nordisk's $4.1 billion Clayton expansion, Johnson & Johnson's $2 billion Wilson biologics campus, Fujifilm's $3.2 billion Holly Springs plant, and Biogen's newly announced $2 billion addition to roughly $10 billion it has already invested in the Triangle since 1995. Even Apple's marquee 2021 win needed a four-year extension in November 2025 after construction stalled. The Park now covers 7,000 acres and 22.5 million square feet, home to 300-plus companies and more than 50,000 employees -- and the state that built the Park by fiat in 1959 is still intervening directly, phasing its corporate income tax to zero by 2030.

Start with why North Carolina built a research park instead of waiting for one to happen. The state's 1950s economy ran on tobacco, textiles, and furniture -- low-value-add industries with a ceiling -- and in 1954 North Carolina's own Research Commission concluded its most underused asset was three research universities sitting an hour apart. UNC sociologist Howard W. Odum first proposed linking Duke, UNC-Chapel Hill, and NC State around a shared research park; Governor Luther Hodges' administration formally incorporated the Research Triangle Committee in September 1956, and Research Triangle Park opened in 1959.^[1] Five companies were on site by the end of that first year, led by the Research Triangle Institute -- now RTI International -- as the Park's literal first tenant, with Chemstrand, inventor of Astroturf, close behind.^[2]

For half a decade, the bet looked like it might not pay off. No other major tenant landed between 1960 and 1965, and people inside the project began doubting it would survive. That changed in 1965, when IBM announced a 400-acre, 600,000-square-foot research facility built specifically for its System/360 mainframe project, arriving the same year as the National Institute of Environmental Health Sciences.^[2] IBM became the Park's largest employer for the next six decades, eventually occupying a four-building, 774,000-square-foot campus that at its peak held more than 10,000 workers on a single site.^[3]

Six decades of compounding turned a few hundred thousand square feet into one of the largest research parks in the country. RTP now covers 7,000 acres and more than 22.5 million square feet of built space, up from roughly 200,000 square feet in 1960, and is home to more than 300 companies and national labs and over 50,000 full-time employees -- past the Park's dot-com-era peak of 45,000 in 2001.^[4]

And in 2025, the company that saved the Park is the one packing up. IBM is consolidating its Triangle workforce into a single leased complex, RTP 500 -- a building it sold to developer Hines for $66 million in 2023 and now rents back -- while it "explores options" for the long-term future of its original 400-acre Cornwallis Road campus.^[3] The Raleigh Chamber of Commerce now estimates roughly 8,000 IBM employees remain in the Triangle, down from a single-site peak that once topped 10,000.^[3]

While IBM shrinks, an entirely different industry is expanding into the same ground. North Carolina pulled in $10.8 billion in life sciences manufacturing investment in 2024 alone -- Novo Nordisk's $4.1 billion Clayton expansion, Johnson & Johnson's $2 billion Wilson biologics campus, and Fujifilm's $3.2 billion Holly Springs biomanufacturing plant among the largest single projects.^[5] Biogen alone has put roughly $10 billion into its Triangle manufacturing footprint since 1995 and announced another $2 billion on July 21, 2025 -- an eighth factory, its first built for antisense oligonucleotide drugs, came online that same year on top of seven already running.^[6]

The fourth region this site has found running the same seed-then-anchor mechanism -- with a twist none of the others show yet Stanford's industrial park leased land to Lockheed; MIT's Lincoln Laboratory spun Route 128 out of federal defense research; IBM and Xerox both used Upstate New York as their own founding factory town before either company moved on. Research Triangle Park runs the identical structure -- research infrastructure built first, an anchor tenant second -- except here the state built the infrastructure directly, across three competing universities, instead of one university spinning off a single lab. RTP is showing the mechanism's other half in real time: the anchor that made a region can leave, and a region built to hold one anchor turns out to hold the next one just as well. The Silicon Valley piece is here; the Boston piece is here; the Upstate New York piece is here.

The region's newest marquee win shows the same pattern isn't automatic. Apple accepted up to $845 million in North Carolina tax incentives in 2021 in exchange for a $1 billion regional investment, including a 1-million-square-foot RTP campus meant to bring roughly 3,000 jobs averaging $187,000 a year.^[7] Construction was due to start in 2026; in November 2025, the state's Economic Investment Committee granted Apple a four-year extension after the company asked to delay.^[8] Landing an anchor and keeping it on schedule are two different things, even now.

The state that built RTP by fiat in 1959 is still choosing to intervene -- just with a different tool. North Carolina's corporate income tax dropped to 2.25% in 2025 and is scheduled to fall to 2% in 2026, 1% in 2028, and zero by 2030, a five-year phase-out enacted while Biogen and Fujifilm were actively deciding where to put billions.^[9] The 1959 version of that instinct was a state government building a research park instead of waiting for one to happen. The 2030 version is a state government eliminating its own corporate tax instead of waiting for the next Biogen to ask.

RTP was never a bet on any single company, even though three decades of history let people treat IBM as the whole story. The bet was on the researchers, the buildings, and the state's own willingness to keep intervening -- and sixty years later, with its founding tenant packing boxes, that bet is the reason the Triangle just had its largest investment year on record instead of its last one.

The takeaway North Carolina built Research Triangle Park in 1959 as a deliberate state bet on its three underused research universities -- Duke, UNC, and NC State -- after tobacco and textiles stopped being enough. Nothing else landed for half a decade until IBM arrived in 1965 with a facility for its System/360 mainframe, becoming the Park's anchor tenant and largest employer for six decades, at times topping 10,000 workers on one site. In 2025 IBM is consolidating into a single leased building and exploring options for its original campus, down to roughly 8,000 Triangle employees -- the same year North Carolina pulled in $10.8 billion in life sciences manufacturing investment (Novo Nordisk, Johnson & Johnson, Fujifilm) and Biogen announced another $2 billion on top of $10 billion already invested since 1995. Even Apple's 2021 win needed a four-year timeline extension in November 2025. The Park now runs 7,000 acres, 22.5 million square feet, 300-plus companies, and 50,000-plus employees -- and the state that built it by fiat in 1959 is still intervening directly, phasing its own corporate income tax to zero by 2030. The anchor changed. The state's willingness to keep building the ground underneath it didn't.
