Blue-chip shares can be a good place to look when building long-term wealth.
The best of them are not just large companies. They have strong market positions, proven management teams, and the ability to keep reinvesting for growth through different market conditions.
With that in mind, here are three ASX 200 blue-chip shares that could be worth buying now.

Goodman Group (ASX: GMG)
Goodman Group has become one of the most important infrastructure businesses on the ASX.
Its warehouses and logistics properties help companies move goods through increasingly complex supply chains. But the company's opportunity has widened in recent years as digital infrastructure becomes a larger part of its growth story.
Large-scale data centres need land, power access, planning expertise, and customers with deep balance sheets. Goodman has many of the ingredients required to serve that demand.
This gives the company a rare combination. Its core logistics business is still supported by ecommerce and supply chain investment, while its data centre pipeline gives it exposure to cloud computing and artificial intelligence.
ResMed Inc (ASX: RMD)
ResMed is another ASX 200 blue-chip share with a strong long-term case.
The company sits in a part of healthcare where demand is still building. Sleep apnoea remains underdiagnosed globally, and better awareness of sleep health continues to bring more patients into treatment.
ResMed's strength is that it is not just selling devices. Its masks, machines, software, and connected-care tools create a broader ecosystem that supports patients, clinicians, and healthcare providers.
That is important because healthcare systems are increasingly trying to deliver more care outside hospitals. ResMed's products fit neatly into that shift, helping people manage chronic conditions at home.
Its latest results also showed the business remains in good shape, with revenue growth, margin expansion, and strong cash generation. That gives investors more confidence that the company can keep investing while still delivering earnings growth.
Wesfarmers Ltd (ASX: WES)
Wesfarmers has earned its blue-chip status through decades of disciplined execution.
The group owns some of Australia's strongest retail businesses, with Bunnings at the centre. Bunnings is a retail machine with scale, customer trust, strong supplier relationships, and deep relevance to both households and trade customers.
Kmart and Officeworks add further earnings streams, while the group's chemicals and industrial operations provide exposure outside retail.
What makes Wesfarmers attractive is its capital discipline. The company has a long history of buying, building, selling, and reinvesting with shareholders in mind.
That flexibility is valuable. Wesfarmers does not need every division to fire at the same time. It has multiple levers and a management culture focused on returns.
