Having some blue chip ASX 200 shares in an investment portfolio is never a bad thing. After all, they can form a strong foundation to build out from.

But not all blue chips are equal and some should arguably be left on the sidelines.

So, which blue chip shares could be good picks for investors with $20,000 to spend as we head into a new month? Let's now take a closer look at two that analysts are tipping as buys. Here's what they are recommending to clients:

Goodman Group (ASX: GMG)

The first ASX 200 blue chip share to consider buying in August is Goodman Group.

It is a global industrial property powerhouse that owns, develops, and manages high quality, sustainable logistics properties and data centres in major global cities, that are critical to the digital economy.

At the last count, its portfolio was valued at $85.8 billion and it had $13.7 billion of development work in progress (WIP) across 66 projects. The latter is heavily focused on data centres, with over 50% of its WIP relating to these assets.

This puts Goodman in a great position to capitalise on the artificial intelligence (AI) boom and continue delivering the goods for investors long into the future.

The team at Morgan Stanley is feeling very positive about its outlook. As a result, it recently put an overweight rating and $40.47 price target on its shares.

WiseTech Global Ltd (ASX: WTC)

Another ASX 200 blue chip share that could be a buy in August is WiseTech.

It is a leading provider of logistics solutions software that helps power international supply chains.

This is achieved through the CargoWise platform, which is a cloud-based, integrated software platform that provides a comprehensive suite of tools for managing various aspects of logistics operations. This includes freight forwarding, customs and compliance, and warehouse management.

The team at Bell Potter is very positive on the company's outlook and feels that its shares are good value right now compared to peers. It notes that "WiseTech and Technology One trade on similar FY26 EV/EBITDA multiples and PE ratios and in our view WiseTech deserves to trade on a premium given its superior growth outlook."

It then adds that it believes "the premium will return, particularly if both the CTO launch and e2open acquisition are successful."

In light of the above, Bell Potter currently has a buy rating and $135.00 price target on WiseTech Global's shares.
